Switching to full fibre from FTTC: what changes at home? A practical 2026 UK guide

1. FTTC versus FTTP: the technical difference and why it matters

Understanding the technical difference between FTTC and FTTP helps explain why the upgrade is worthwhile and what physically changes at home.

• FTTC (Fibre to the Cabinet) is part fibre, part copper. Per broadband.co.uk, FTTC stands for Fibre to the Cabinet; fibre optic cables run from the local exchange to a green street cabinet you'll have walked past on UK pavements; from there your home is connected using your existing copper phone lines to complete the circuit. Per broadband.co.uk, FTTC broadband typically gives download speeds between 40 and 80 Mbps.
• FTTP (Fibre to the Premises) is full fibre with no copper. Per broadband.co.uk, FTTP stands for Fibre to the Premises; fibre optic cables run directly from the service provider's network into your home or office. Per broadband.co.uk, fibre optic cables are designed to carry large amounts of data quickly; that's why FTTP can offer incredibly fast speeds. It's also called full fibre broadband because there's no copper in the internet connection at all. The result is a more reliable, consistent internet.
• Speed difference is substantial. Per CompareFibre, current FTTC delivers under 50 Mbps in many areas due to distance from cabinet degrading speeds and households experiencing peak-hour congestion (evening 7-11pm speeds degrading); FTTP 150 Mbps delivers 3x speed improvement enabling 4K streaming, professional working from home, and gaming. Higher FTTP tiers reach 300 Mbps, 500 Mbps, 900 Mbps, 1.6 Gbps (EE Full Fibre 1.6 Gbps £47.99/mo), or 2.2 Gbps (Vodafone Pro II on CityFibre).
• Reliability difference is also substantial. Per The VoIP Shop, full fibre uses fibre for the full distance, so the signal stays strong at all times. Copper segments on FTTC are subject to electromagnetic interference, water ingress, and signal degradation over distance; full fibre eliminates these.
• Upload speed. FTTC typically delivers up to 20 Mbps upload (slower than 80 Mbps download asymmetric). FTTP entry tiers are typically asymmetric (BT Full Fibre 100 has 30 Mbps upload; Plusnet Full Fibre 145 has approximately 30 Mbps upload), but mid-to-high tiers from 500 Mbps upward typically offer symmetric or near-symmetric upload, particularly on altnet XGS-PON networks (Hyperoptic at every tier, Vodafone Pro II at 2.2 Gbps symmetric, Toob 900 Mbps symmetric).
• Latency. Per Fusion Fibre Group, full fibre broadband reduces lag and improves online performance; FTTP typically delivers 5-15 ms ping versus FTTC at 20-40 ms. This matters most for online gaming, video calling, and real-time collaboration tools.
• Future-proofing. Per The Unite Group, SoGEA does not depend on the PSTN so FTTC-derivative broadband-only services are unaffected by the 31 January 2027 PSTN switch-off; however, FTTP is the long-term path with Openreach planning the full fibre upgrade across the UK and BT having already announced legacy line price doubling by October 2026 per ISPreview UK.

2. What physically changes at home during the upgrade

The physical changes at home when upgrading from FTTC to FTTP are straightforward and reversible. Per CompareFibre and Fusion Fibre Group, the main visible differences are the new fibre cable route, the small external junction box, plus the internal ONT. This section walks through each change.

• New fibre cable from the street to your property. Per CompareFibre, the engineer runs a fibre cable from the nearest distribution point to your home; this is typically through existing underground ducts (where the existing copper phone line is fed underground) or overhead from a pole (where the existing copper is fed from poles). Per BT Community, in some areas the Openreach phone lines are fed from poles and in others underground; if your area has phone lines fed from poles, the chances are the fibre will also be fed overhead.
• Small external junction box. Per CompareFibre, the engineer installs an external junction box (a small white plastic enclosure) on the property exterior wall near the fibre entry point; this junction box connects the underground or overhead fibre cable from the street to the premises. The box is roughly the size of a small paperback book.
• New small hole through an external wall (if needed). Per CompareFibre, if no existing duct or entry point can be reused, the engineer drills a small hole approximately 10mm through an external wall. Per The VoIP Shop, the engineer makes the hole tidy. Per CompareFibre, the engineer discusses the route with you before drilling and makes good the hole afterwards. Where an existing phone line entry hole is reusable, no new hole is needed.
• Internal Optical Network Terminal (ONT). Per CompareFibre, an ONT is the box the engineer installs to connect the incoming fibre cable to your router; it is typically mounted on an internal wall near where the fibre enters your home. Per Fusion Fibre Group, the ONT is usually placed near a power socket and close to where your router will be located. Per CompareFibre, the ONT is usually about the size of a paperback book. Per The VoIP Shop, the unit stays powered at all times because it drives your internet connection; it stays silent and plugs into a standard socket.
• Router connects to the ONT via Ethernet, not the master phone socket. Per the BBS guide on full fibre versus FTTC, the router connects to the ONT via Ethernet rather than to a master phone socket as on FTTC. This is the most fundamental shift in home setup. Your existing Ethernet-connected devices (smart TVs, games consoles, hardwired desktops) connect to the new router as before; Wi-Fi-connected devices reconnect to the new router's Wi-Fi network using the new credentials.
• Master phone socket no longer carries broadband. Per the BBS guide on full fibre versus FTTC, the existing master phone socket on the wall (typically the NTE5A or NTE5C type) no longer carries broadband signal once FTTP is active. If you want to keep landline calling capability, the phone connects to the back of the new FTTP router via a digital voice adapter (or directly into a router socket designed for this purpose) per ISPreview UK; the master phone socket itself becomes redundant for both broadband and voice.
• Power requirement. Per The VoIP Shop, the ONT stays powered at all times. An additional power socket near the ONT location is needed; most installations use the same power socket that previously powered the FTTC router (or a nearby socket). Power consumption is minimal (typically 5-10 W).
• New router (typically provided). Most major UK ISPs supply a new router suited to FTTP speeds. BT supplies the Smart Hub or Smart Hub Plus depending on speed tier; Sky supplies the Sky Broadband Hub or Sky Hub Plus mesh router; Vodafone supplies the Vodafone WiFi Hub for FTTP; EE supplies the EE Smart Hub; Plusnet supplies the Plusnet Hub Two; altnets including Hyperoptic, Community Fibre, plus Zen Internet supply their own FTTP-suited routers. The new router typically supports Wi-Fi 6 or Wi-Fi 6E and delivers materially better Wi-Fi than older FTTC routers.

3. The engineer visit: what to expect on the day

The engineer visit is the main practical event in the FTTC-to-FTTP upgrade. Per CompareFibre, FTTP installation typically takes 2-4 hours and requires someone over 18 at home. This section walks through what happens during the visit.

• Appointment window and adult presence required. Per CompareFibre, an adult aged 18 or over must be present at the property for the duration of the appointment; appointment windows are typically 4 hours. Per CompareFibre, for Openreach installs covering BT, Sky, Plusnet, Vodafone, EE, NOW Broadband and others, an Openreach engineer arrives during a booked morning (8am-1pm) or afternoon (1pm-6pm) slot.
• Engineer arrival and external survey. Per CompareFibre, the engineer first surveys the outside of the property to identify the best cable route, through existing ducts, along walls, or overhead; they explain the planned route and confirm the ONT location with you before starting work.
• Cable route from the street to the home. Per CompareFibre, the engineer runs fibre from the nearest street distribution point through existing underground ducts where available, or overhead from a pole, to a small external junction box on the property exterior wall. Where existing ducts are reusable (typically the existing phone line route), no new outdoor work is needed beyond fitting the junction box.
• Drilling if needed. Per CompareFibre, if no duct exists, the engineer drills a small hole approximately 10mm through an external wall. Per Fusion Fibre Group and The VoIP Shop, the hole is tidy; the engineer discusses the entry point with you before drilling. Per CompareFibre, where an existing phone line hole can be reused for fibre, no new drilling is needed.
• ONT mounting and configuration. Per CompareFibre, inside the property the ONT is mounted on the wall and connected to the fibre cable. Per The VoIP Shop, the engineer checks that the ONT shows the correct lights and confirms the signal is stable. Per Fusion Fibre Group, the ONT is usually placed near a power socket and close to where the router will be located.
• Router connection and configuration. Per CompareFibre, the ISP's router then plugs into the ONT via an Ethernet cable. Per Fusion Fibre Group, the engineer connects your router to the ONT and configures it for your new ultrafast broadband.
• Speed test on completion. Per CompareFibre, the engineer tests the connection to confirm speeds match your package; for example, a 900 Mbps package should deliver at least 700-800 Mbps over a wired test. This test is the moment to verify the line is delivering close to the headline package speed.
• Cleanup and walk-through. The engineer cleans up any debris from drilling, makes good any hole around the cable, and walks you through the new equipment, including how to log into the router admin interface, how to access the Wi-Fi network with the new credentials, and how to contact support if issues arise.

4. What stays the same: devices, Wi-Fi, phone number

The FTTC-to-FTTP upgrade introduces new equipment but most of your home tech stays the same. Understanding what stays the same helps set expectations and avoids unnecessary purchases.

• All your devices stay the same. Laptops, smartphones, tablets, smart TVs, games consoles, smart home devices (Alexa, Google Home, smart bulbs, smart thermostats, smart doorbells, security cameras), printers, plus other Wi-Fi or Ethernet-connected devices all keep working with the new router. No device replacement is needed.
• Wi-Fi typically improves. Provider-supplied FTTP routers typically deliver materially better Wi-Fi than older FTTC routers (Wi-Fi 6 or Wi-Fi 6E versus older Wi-Fi 5); range, capacity for multi-device households, plus speed for individual devices all improve substantially. Households on older FTTC routers often see meaningfully better Wi-Fi performance even before considering the line speed improvement.
• Mesh systems and third-party Wi-Fi extensions transfer. If you've added BT Whole Home, Sky Hub Plus mesh, Virgin Media Pod, or third-party mesh systems (Eero, Google Nest WiFi, TP-Link Deco, Asus ZenWiFi) to your existing FTTC setup, these typically continue working with the new FTTP router; reconfigure the mesh system to point at the new router.
• Phone number can be retained through Digital Voice. Per Which?, BT Digital Voice retains your existing phone number through the broadband; equivalent services from Sky, TalkTalk, plus other major UK ISPs work the same way. Per gov.uk, you can typically keep your existing landline number when migrating; number portability between providers follows standard UK number portability rules. See the BBS guide on switching broadband without a landline for the framework.
• Existing Ethernet cable runs in your home stay the same. If you have Ethernet cable runs in walls, in skirting, or behind furniture, these all continue working; the new router has the same RJ45 Ethernet ports as your old one.
• Smart home automation rules stay the same. Smart home routines, voice assistant configurations (Alexa skills, Google Home routines, Apple HomeKit automations), security camera schedules, plus other automation all keep working through the new router as long as devices reconnect to the new Wi-Fi network with the new credentials.
• VPN configurations stay the same. Personal VPN setups (NordVPN, ExpressVPN, ProtonVPN, Mullvad), corporate VPN connections for working from home, plus router-level VPN configurations all keep working through the new connection; the FTTP line typically delivers materially better VPN throughput than FTTC due to the higher upload speed.
• Email accounts and online services stay the same. Your provider may issue a new email address (BT and TalkTalk historically supplied email accounts); these typically transfer or continue alongside the new service. Per the BBS guide on switching broadband, where you switch provider as part of the FTTP upgrade, the old provider typically maintains email accounts for 90 days after service cessation per major UK ISP terms of service.

5. Order-to-activation timeline and process

The standard FTTC-to-FTTP upgrade timeline is 1-2 weeks per CompareFibre. This section walks through each step.

1. Step 1 (day 0): Check FTTP availability at your address. Run a postcode check at the chosen provider's website to confirm Openreach FTTP (or altnet FTTP) is available. Per Openreach via ISPreview UK March 2026, FTTP coverage has reached 22 million UK premises with 25 million targeted by December 2026; some addresses are still awaiting build.
2. Step 2 (day 0): Compare packages and place the order. Compare FTTP packages across providers (BT, Sky, Vodafone, TalkTalk, EE, Plusnet, NOW Broadband, Zen Internet on Openreach plus altnet retail brands). Place the order online or by phone; the One Touch Switch process per CompareFibre handles cross-provider transitions through the new provider only if you're switching ISP as part of the upgrade.
3. Step 3 (day 1-3): Order confirmation and engineer appointment booking. Per CompareFibre, the new provider sets a switch date typically within 10 working days; you receive confirmation by email or text along with details of any new equipment being sent. The engineer appointment is typically 4-10 days after order placement.
4. Step 4 (day 4-10): Equipment delivery (router). The new router arrives by post 1-3 days before the engineer appointment. Don't connect it yet; the engineer will set it up on the install day.
5. Step 5 (day 7-14): Engineer visit and FTTP installation. Per CompareFibre, FTTP installation typically takes 2-4 hours and requires someone over 18 at home; the engineer surveys the property, runs fibre from the street, mounts the external junction box and internal ONT, connects the router, tests the connection, and walks you through the new setup. Service typically activates immediately at the end of the install.
6. Step 6 (day 7-14): Old service ceases. Per CompareFibre, if you are switching from an existing broadband service, your old service will stop at the same time your new service activates; for cross-provider switches via One Touch Switch the cessation is automated through the TOTSCo Hub messaging platform per the BBS guide on One Touch Switch.
7. Step 7 (day 14-28): Equipment return for old provider. Where switching to a different provider as part of the FTTP upgrade, return the old provider's router and equipment using the prepaid return service per provider terms (typically within 14-28 days of switch); failure to return may result in a non-return charge typically £30-£50.
8. Step 8 (day 14-30): Final billing reconciliation. Final bill from old provider; first bill from new provider; any pro-rata refunds or charges. Where Automatic Compensation is due (per Ofcom, £6.10 per day for activation delays, £30.49 per missed engineer appointment under April 2026 rates), this is typically credited to your new account or paid as a refund.

6. Openreach FTTP availability and rollout in 2026

Openreach is the dominant UK FTTP infrastructure provider supporting most major UK ISPs. Per ISPreview UK March 2026, Openreach's FTTP network has so far covered 22 million UK premises with the average build rate currently around 1 million UK premises per quarter and a take-up rate of 38% (rising to over 50% in older cohorts). This section covers Openreach FTTP availability.

• Current footprint (January 2026 baseline) and growth. Per CompareFibre and ISPreview UK, Openreach's network expansion reached 17.1 million premises (50% UK coverage) by January 2026; per ISPreview UK March 2026, the network has so far covered 22 million UK premises (approximately 65% of the UK's c.33m premises). Average build rate of around 1 million UK premises per quarter continues.
• 2026 target. Per ISPreview UK and Openreach, the operator is currently investing up to £15 billion to expand the coverage of its full fibre network to 25 million premises by December 2026, including around 6.2 million in rural or semi-rural areas.
• 2030 target. Per ISPreview UK, Openreach has expressed an ambition to reach up to 30 million premises by 2030 (out of approximately 33 million in the UK), although this is partly dependent upon a favourable outcome from Ofcom's next Telecoms Access Review 2026 (TAR) and government policy on planning and taxation.
• Build rate and resources. Per ISPreview UK, Openreach currently has 15,000 people focused on UK FTTP deployment with the average per-premises build cost continuing to hover around £300 (roughly £1.2bn per year).
• Speed capability. Per ISPreview UK, the new network is currently capable of delivering download speeds of up to 1.8 Gbps (uploads of 1 Gbps are also possible in some Project Gigabit build areas) via older GPON technology; Openreach is also about to trial real speeds of up to 8.5 Gbps via the new XGS-PON full fibre network across tens of thousands of premises around Guildford.
• Available ISPs on Openreach FTTP. Per ISPreview UK, the new service once live can be ordered via various ISPs including BT, Sky Broadband, TalkTalk, Vodafone, EE, Plusnet, NOW Broadband, Zen Internet, plus many more. Openreach maintains a public list of FTTP-supporting ISPs; the choice is wide.
• Not currently an automatic upgrade. Per ISPreview UK, FTTP is not currently an automatic upgrade from FTTC, although some ISPs have started to do free automatic upgrades as older copper-based services and lines are slowly withdrawn. Per the EE Community discussion, only certain packages have what is known as the Full Fibre Guarantee where it is supposed to be a somewhat automatic upgrade to the entry level tier of Full Fibre plans (Fibre 67 to Full Fibre 150 for example).
• Build transparency. Per ISPreview UK March 2026, Openreach has refreshed the status of all 3,525 exchanges selected for commercial build to give people clearer information about when to expect full fibre build to start; the latest March 2026 build plan and interactive map gives transparency on commercial rollout up to the December 2026 target.

7. Major UK ISP FTTP packages compared

Comparing major UK ISP FTTP packages helps surface genuine value across the market. This section provides an overview of the most popular FTTP options.

8. Altnet FTTP options where Openreach hasn't reached

Where Openreach FTTP hasn't reached your address yet, UK altnet providers may offer FTTP coverage. Per CompareFibre, regional altnets including Hyperoptic, Community Fibre, plus Gigaclear collectively cover 2-3 million premises; the wider altnet ecosystem covers more. This section covers the major altnet FTTP options.

• CityFibre wholesale FTTP. Used by Vodafone Pro II up to 2.2 Gbps, Sky Gigafast, TalkTalk Future Fibre, Zen Internet, plus retail altnets including Cuckoo, Giganet, iDNET. CityFibre covers approximately 4.7 million UK premises (4.5 million ready for service per ISPreview March 2026).
• Hyperoptic. UK-wide altnet specialising in MDU (multi-dwelling unit) buildings. Per Opensignal December 2025, Hyperoptic serves 1.9 million UK premises with top-five Ofcom customer satisfaction (approximately 4 complaints per 100,000 customers). Symmetric upload speeds at every tier from 50 Mbps to 1 Gbps; monthly rolling contracts available; Hyperoptic Fair Fibre social tariff at £12/mo for 50 Mbps for qualifying households.
• Community Fibre. London-only altnet with strong customer satisfaction. Per Opensignal December 2025, Community Fibre outright tops Download and Upload Speeds, Consistent Quality, Reliability Experience, plus jointly leads in Video Experience in London.
• Gigaclear. Rural-focused altnet with substantial UK rural FTTP coverage; particularly strong in rural Oxfordshire, Gloucestershire, Devon, Berkshire, plus other rural counties where Openreach FTTP is later in the build pipeline.
• YouFibre. UK altnet with growing footprint; symmetric speeds at higher tiers; competitive pricing. Recently merged with brsk per ISPreview.
• Toob. Altnet operating on CityFibre wholesale plus its own builds; per toob, 900 Mbps symmetric with the toobpromise (fixed price for contract term). Active across CityFibre footprint including Swindon, Slough, plus other CityFibre locations.
• BeFibre. UK altnet with regional builds plus partnerships with major networks.
• brsk. UK altnet with strong Manchester, Leeds and Bradford, plus wider regional presence; per Opensignal December 2025, brsk shares the top position across all metrics in Manchester and Leeds and Bradford.
• Netomnia (4th Utility). UK altnet with strong MDU presence; 4th Utility specialises in apartment block broadband with monthly rolling contracts.
• Ogi. Welsh altnet with substantial Wales coverage including Cardiff, Swansea, Newport, plus rural Wales builds.
• Other regional builders. Truespeed in South West, Voneus in rural England, plus dozens of smaller altnets and regional builders provide FTTP in specific regions.

9. Cost changes: typical pricing differences and savings

Upgrading from FTTC to FTTP typically delivers materially better speeds at competitive pricing; in many cases the FTTP package matches or beats the FTTC plus phone line equivalent. This section covers the typical cost dynamics.

• FTTC + phone line baseline. A typical UK 2026 FTTC plus phone line bundle runs approximately £30-£40 per month at the headline 65-80 Mbps tier including line rental. Per Connection Technologies, traditional FTTC at £30 per month plus £18 line rental was £48 per month; modern bundles have integrated line rental into headline pricing.
• FTTP entry tier pricing. Vodafone Full Fibre 80 from approximately £22/mo; Plusnet Full Fibre 74 from approximately £24/mo; BT Full Fibre 100 from approximately £30/mo; Sky Full Fibre 100 around £28-£32/mo. All broadband-only (no line rental).
• Typical net change at the entry FTTP tier. Switching from a £35/mo FTTC bundle to Vodafone Full Fibre 80 at £22/mo saves approximately £13/mo while delivering similar speeds; switching to BT Full Fibre 100 at £30/mo saves approximately £5/mo while delivering 100 Mbps versus FTTC's typically sub-50 Mbps real-world speed per CompareFibre.
• FTTP mid tier pricing. BT Full Fibre 500 around £40/mo; Sky Full Fibre 500 around £37-£40/mo; Plusnet Full Fibre 500 around £33/mo; Vodafone Full Fibre 500 around £29/mo. All broadband-only.
• FTTP premium tier pricing. BT Full Fibre 900 around £45/mo; Sky Full Fibre 900 around £42/mo; EE Full Fibre 1.6 Gbps £47.99/mo (the highest standard Openreach tier); Vodafone Pro II 2.2 Gbps on CityFibre around £60-£70/mo; Virgin Media Gig1 1.1 Gbps around £43-£48/mo (cable network); Hyperoptic 1 Gbps symmetric around £40-£50/mo.
• Mid-contract rises. Per the BBS guide on UK broadband mid-contract rises, major UK ISPs apply approximately £3-£4 per month April 2026 increases (BT and EE £4/mo flat from 31 March 2026; Sky £3/mo flat from 1 April 2026; Vodafone £3.50/mo from April 2026 for contracts post 2 July 2024; Virgin Media £4/mo new contracts and £3.50/mo in-contract from April 2026). Most altnets including Hyperoptic, Zen Internet (Contract Price Promise), plus Toob (toobpromise) offer fixed pricing or no mid-contract rises during the contract term.
• Setup fees. Per CompareFibre, setup fees are usually £0 on 18-24 month contracts. Engineer install for FTTP is typically included in the contract; new builds since December 2022 must have FTTP infrastructure pre-installed under building regulations per CompareFibre, so installation is often even simpler.
• Social tariffs. Where FTTP is being chosen during a household budget tightening or after qualifying for benefits (Universal Credit, Pension Credit, Income Support, similar), social tariffs are available: BT Home Essentials at £15/mo for 36 Mbps; Hyperoptic Fair Fibre at £12/mo for 50 Mbps in connected MDU buildings; Virgin Media Essential Broadband. See the BBS UK broadband social tariffs guide.

10. Related UK consumer rights (cooling-off, automatic compensation, ADR)

Upgrading from FTTC to FTTP interacts with the wider 2026 UK consumer protection framework. This section covers the relevant rights.

• 14-day cooling-off period. Per CompareFibre, customers have a 14-day cooling-off period after signing any new broadband contract during which they can cancel without penalty. This applies to all FTTP orders. Per CompareFibre, providers cannot charge exit fees during the cooling-off period.
• Voluntary Code of Practice on Broadband Speeds. Per Ofcom, the right to exit if speeds fall below the Guaranteed Minimum Speed (GMS) and aren't restored within 30 days applies to FTTP services. Most major UK ISPs (BT, EE, Plusnet, Sky, NOW Broadband, Vodafone, TalkTalk, Virgin Media, Zen Internet) are signatories per Ofcom. See the BBS guide on leaving broadband early due to poor speeds.
• Automatic Compensation scheme with April 2026 rates. Per Ofcom and CompareFibre, the scheme pays £6.10 per day if your service is not activated by the agreed date under April 2026 rates; £30.49 for missed engineer appointments; £10.74 per day for total loss of service after two working days. This is particularly relevant during the FTTP install where engineer delays can occur.
• Telecoms Consumer Charter (introduced February 2026). Sector-wide Charter setting out minimum customer service standards across UK ISPs.
• One Touch Switch. Per CompareFibre and Switchity, OTS launched 12 September 2024 lets customers change provider by contacting only the new provider; over 1.6 million households used OTS in its first year. Where you're switching ISP as part of the FTTP upgrade, OTS handles the cross-provider transition through the new provider only.
• End-of-contract notification. Per CompareFibre, providers must send an end-of-contract notification 10-40 days before the existing FTTC deal expires, clearly showing what you're currently paying and the best deals available. This is the natural trigger to consider FTTP upgrade.
• Alternative Dispute Resolution (ADR). Per Consumer Voice, all UK broadband providers must be members of an ADR scheme (Communications Ombudsman or CISAS). After 8 weeks of unresolved complaint, customers can escalate to ADR for binding adjudication; this applies to FTTP install disputes equally to other broadband matters.
• Wayleave protections via TILPA 2021. In flat blocks (MDU buildings), the Telecommunications Infrastructure (Leasehold Property) Act 2021 framework applies if landlord wayleave is needed and not provided within 35 days; broadband companies may seek court access per Rocket Lawyer UK. See the BBS guide on switching broadband in a rented property.
• Consumer Rights Act 2015. Underlying statutory protection: services must be "fit for purpose" and "of satisfactory quality"; alternative legal route where Voluntary Code or specific provider commitments don't apply.

11. Practical scenarios: rural household, urban professional, family upgrade

This section walks through three typical UK 2026 scenarios to illustrate how FTTC-to-FTTP upgrades work in practice.

Scenario 1: The rural household where Openreach FTTP has just arrived

The Williams family lives in a rural Berkshire village (RG postcode area). They've been on FTTC at approximately 35 Mbps for years; speeds drop to under 25 Mbps during evening peak hours. Openreach has just completed the FTTP build for their village and they receive a letter from BT inviting them to upgrade.

• Step 1: Compare options. The family checks BT's BT Full Fibre 100 at approximately £30/mo (similar to current bundle), BT Full Fibre 500 at approximately £40/mo (premium upgrade), Vodafone Full Fibre 80 at approximately £22/mo (cheapest option for entry-level FTTP), plus Plusnet Full Fibre 145 at approximately £27/mo (BT Group value brand). They choose BT Full Fibre 500 for premium speed.
• Step 2: Place order. Order placed online with BT; engineer appointment booked for 9 days later. Router delivered by post 5 days before install.
• Step 3: Engineer install. Openreach engineer arrives in the morning slot per CompareFibre; surveys the property; runs new fibre cable from the existing pole route (overhead) to the front of the house through an existing duct; installs small external junction box; runs fibre through existing phone line entry hole; mounts ONT inside near the existing FTTC router location; connects new BT Smart Hub Plus router; tests connection at 540 Mbps download, 75 Mbps upload (above the BT Full Fibre 500 GMS).
• Step 4: Family reconnects devices. Smart TVs, laptops, phones, smart home devices, plus games consoles all reconnect to the new BT Wi-Fi network using new credentials. No device replacement needed. Wi-Fi performance materially improved by the new Wi-Fi 6 router.
• Step 5: Old FTTC service ceases automatically. Per CompareFibre, the old service stops at the same time the new service activates. Old router returned to BT in the prepaid return bag within 14 days.
• Outcome. 500 Mbps consistent FTTP service replacing previously 25-35 Mbps FTTC; £40/mo replacing previously £35/mo FTTC plus line bundle; family ready for the PSTN switch-off scheduled 31 January 2027 per Ofcom and gov.uk; phone retained through Digital Voice with the same number.

Scenario 2: The urban professional moving from FTTC to altnet FTTP via OTS

Sophia rents a flat in central Manchester (M1 postcode). Her building has both Openreach and brsk infrastructure (per Opensignal December 2025, brsk shares the top position across all metrics in Manchester). She's currently on a Sky FTTC bundle approaching contract end and wants to upgrade to a high-speed altnet FTTP service.

• Step 1: Compare options. Sky FTTP on Openreach (BT-Group brand uses Openreach FTTP); Vodafone Pro II on CityFibre at 2.2 Gbps; brsk symmetric on its own network with strong customer satisfaction; Hyperoptic in connected MDU buildings. Sophia chooses brsk for the symmetric speeds plus Manchester customer satisfaction leadership per Opensignal December 2025.
• Step 2: Order via One Touch Switch. Per CompareFibre, OTS handles the cross-provider transition through the new provider only. brsk's order process uses OTS to coordinate cessation of the existing Sky FTTC service.
• Step 3: brsk engineer install. brsk engineer attends within 7 days; brsk's wayleave with the building means in-flat installation is straightforward; ONT mounted near existing FTTC router location; brsk router connected; symmetric 1 Gbps service active same day.
• Step 4: Sky FTTC service ceases via OTS. Per CompareFibre, the OTS process automatically coordinates Sky's cessation through the TOTSCo Hub messaging platform. Sky's final bill arrives within 30 days; Sky equipment returned in prepaid return bag.
• Outcome. Symmetric 1 Gbps brsk FTTP replacing approximately 60 Mbps FTTC; substantially better Wi-Fi from the new router; Sophia's working-from-home video calling, content creation, plus cloud syncing all materially improved.

Scenario 3: The family upgrade with Hyperoptic in a London MDU

The Khan family rents a flat in Canary Wharf (E14 postcode). The building has both Openreach FTTC plus Hyperoptic infrastructure (Hyperoptic has wayleave with the building). They've been on a Plusnet FTTC contract; they want symmetric high speeds plus monthly rolling flexibility for tenancy mobility.

• Step 1: Compare options. Plusnet Full Fibre 145 on Openreach FTTP at approximately £27/mo; BT Full Fibre 500 at approximately £40/mo; Hyperoptic 500 Mbps symmetric monthly rolling at approximately £35/mo. The family chooses Hyperoptic for symmetric upload (one parent runs a small business with cloud syncing), monthly rolling flexibility (12-month tenancy with potential renewal uncertainty), plus Hyperoptic's top-five Ofcom customer satisfaction.
• Step 2: Order via One Touch Switch. Per CompareFibre, OTS handles the cross-provider transition. Hyperoptic order placed online; in-flat installation arranged within 7 days given Hyperoptic's wayleave.
• Step 3: Hyperoptic engineer install. Hyperoptic engineer attends; in-flat installation uses existing Hyperoptic riser infrastructure; ONT mounted near existing FTTC router location; Hyperoptic router connected; symmetric 500 Mbps service active same day.
• Step 4: Plusnet FTTC service ceases via OTS. Plusnet's cessation handled automatically through OTS; Plusnet final bill arrives within 30 days.

12. Five questions to ask before upgrading from FTTC to FTTP

Before placing a UK FTTP order in 2026, work through these five questions to confirm the order is right for your situation.

1. What FTTP options are available at my address? Run a postcode check at major UK ISP websites plus altnet checkers. Per ISPreview UK March 2026, Openreach FTTP has reached 22 million UK premises; CityFibre 4.7 million; altnets including Hyperoptic in MDU buildings, Community Fibre London-only, Gigaclear rural, plus YouFibre, Toob, BeFibre, brsk, Netomnia, Ogi cover further premises. Most UK 2026 FTTC addresses have multiple FTTP options.
2. What speed do I need? Light usage 30-100 Mbps suits casual streaming; standard 100-300 Mbps suits multi-device working from home; premium 500-900 Mbps suits content creation plus heavy household usage; multi-gigabit (Vodafone Pro II 2.2 Gbps, EE 1.6 Gbps) suits enthusiast use. See the BBS speed and needs hub.
3. Do I need symmetric upload? Working from home with heavy uploads, video calling, content creation, cloud syncing, plus live streaming benefit from symmetric upload. Hyperoptic (every tier symmetric), Community Fibre (every tier), Toob (900 Mbps symmetric), Vodafone Pro II 2.2 Gbps (symmetric on CityFibre), plus altnet XGS-PON networks deliver this. Most major UK ISPs on Openreach are asymmetric at lower tiers.
4. What contract length suits my situation? Long-term homeowners benefit from 24-month contracts (lowest pricing); renters with 12-month tenancy may prefer 12-month or monthly rolling (Hyperoptic monthly rolling, NOW Broadband no-contract option, Three 5G home broadband for fully transferable). See the BBS broadband contract lengths guide.
5. Do I want to keep my landline number? If yes, Digital Voice (BT Digital Voice, Sky Voice, TalkTalk Voice) per Which? retains the number through the broadband; the phone connects to the back of the new FTTP router. If no, simply order broadband-only. See the BBS guide on switching broadband without a landline.
