Direct answer: Upgrading from copper to fibre broadband when Openreach FTTP reaches your address in 2026 is now the right move for most UK households. The Public Switched Telephone Network (PSTN) will be retired on 31 January 2027, so a copper-based ADSL or FTTC service has at most 20 months of life left. Check FTTP availability at your exact address, compare Total Contract Value, plan for an engineer install, and confirm how your home phone will work after the move.

Key facts on copper to fibre upgrades (May 2026)

Check what is genuinely live at your exact address before deciding.

What does upgrading from copper to fibre when Openreach arrives actually mean?

It means your address has gained Openreach Fibre to the Premises (FTTP), where a fibre-optic cable runs all the way from the exchange to your home.

This is a genuine infrastructure change, not a faster package on the same line. ADSL and FTTC services use copper for the final leg of the connection. ADSL runs copper the whole way from the exchange to your house; FTTC runs fibre to your local street cabinet, then copper from there to your home. Both depend on the copper Public Switched Telephone Network. FTTP removes copper entirely between the exchange and your property.

That change carries three practical consequences. First, your speed becomes far less sensitive to the distance from the exchange or cabinet; it depends instead on the package you buy. Second, a new piece of equipment, the Optical Network Terminal or ONT, is installed inside your home where the fibre enters. Third, the way your home phone works changes, because the PSTN is being retired on 31 January 2027 (Openreach, 2026). Any voice service on a new FTTP line is delivered over the broadband connection as digital voice (also called Voice over IP or VoIP), not over a separate copper pair.

The bigger context matters. Ofcom's Connected Nations update, Spring 2026 records 82% of UK residential premises (24.9 million homes) with FTTP available as of January 2026, up from 78% in July 2025 (Ofcom, 2026a). Gigabit-capable coverage, which combines FTTP and Virgin Media's HFC cable network, sits at 89%. By February 2026, Openreach had also issued FTTC and ADSL stop-sell notices on 1,281 telephone exchanges, covering around 12.5 million premises (Openreach, 2026). Where stop-sell applies, you cannot sign a new copper contract or recontract on an existing copper service. The natural decision is to move to FTTP now, on your terms, rather than be migrated in the final months of the switch-off.

For the technology basics in plain English, see our full fibre vs FTTC vs cable vs 4G/5G guide.

Should you switch as soon as Openreach fibre becomes available?

For most households, yes. The case for waiting becomes weaker every month of 2026 as the PSTN switch-off approaches.

If you are out of contract, the decision is straightforward. Run a postcode check and see whether FTTP deals undercut what you are paying for copper. In many UK postcodes in 2026, an entry-level Openreach FTTP package from BT, Sky, Plusnet, NOW Broadband, Vodafone or an altnet retailer costs the same as, or less than, the equivalent FTTC deal. Altnets such as Community Fibre (London), YouFibre (on the Netomnia network), Gigaclear (rural England), Toob (south coast), Brsk and BeFibre often price more aggressively still inside their build footprints.

If you are still mid-contract, the maths is different. Early exit charges typically equal the remaining monthly fees minus VAT, which can be substantial on a long contract. Compare the cost of staying versus exiting and switching by adding the exit charge to the new package's Total Contract Value. Our exit and setup fees guide walks through the calculation.

One pressure point is increasingly hard to ignore. Openreach has confirmed wholesale price increases on legacy Wholesale Line Rental products through 2026: a 20% rise on 1 April, a further 40% on 1 July, and another 40% on 1 October (Openreach, 2026). These are wholesale increases, so retail providers may or may not pass them through, but the direction of travel is clear: copper services are being made progressively more expensive to encourage migration. Anyone still on copper on 31 January 2027 will be moved to a basic fallback called Emergency Voice Access (EVAC), which is not equivalent to a normal phone line.

There is also the renewal timing angle. If your current contract is within four months of ending, lining up the FTTP switch around your contract end avoids exit charges and uses the One Touch Switch process cleanly. If your copper service is causing problems now, paying an exit fee can still be worth it once you have done the maths.

How is full fibre different from your current copper line?

Full fibre is faster, more symmetrical, more stable, and far less sensitive to distance than copper broadband.

The headline speed difference is the most visible change. A typical UK FTTC line delivers 30 to 70 Mbps download and 7 to 20 Mbps upload, depending on distance from the cabinet. Entry-level FTTP starts at 50 to 80 Mbps and rises to 1 Gbps or beyond, with many altnets offering symmetrical or near-symmetrical upload speeds. Ofcom's Connected Nations UK Report 2025 records average UK fixed-line data use at 583 GB per connection per month in July 2025, with full fibre connections averaging 738 GB, around 30% higher than other connection types (Ofcom, 2025a). Modern household demand has outgrown what FTTC was designed to deliver.

The less obvious differences matter more day to day. FTTC speeds drop noticeably the further your home sits from the street cabinet. Two houses in the same postcode can show different real-world speeds because of line length and condition. FTTP performance is set by the package you buy, not by the copper between you and the cabinet. That makes the service more predictable, especially during peak evening hours when contention used to slow many copper-based connections.

Upload speed is the unsung gain. Video calls, cloud backups, large file transfers and any kind of remote working or content creation depend on upload performance. An FTTC upload at 10 Mbps will frustrate a household running two simultaneous Teams or Zoom calls. A 100 Mbps symmetric FTTP line handles the same load without effort.

If you want a plain-English benchmark for what different speed tiers actually suit, see our broadband speed guide. If your concern is which provider sells FTTP at your address, the FTTP broadband deals page lists current live options. Our specific FTTC to FTTP transition guide covers the practical changes inside the home.

What happens during installation?

An Openreach FTTP install is an engineer visit that lasts 60 to 120 minutes for a standard property, with a new fibre route into the home and a small piece of equipment fitted internally.

The engineer's first job is to run a fibre cable from the nearest Openreach connection point (usually a pole or underground duct) to the outside of your house. This goes through a small box on the external wall. Inside, the fibre terminates in an Optical Network Terminal, the ONT, which is typically a small white plastic unit roughly the size of a paperback book. Your broadband router then plugs into the ONT via an Ethernet cable.

The ONT location matters more than people realise. The natural place to fit it is where the fibre enters, which is often near the front door, in a porch, or under the stairs. That is not always the best place for your router. If your home office or main TV is upstairs, ask the engineer about extending the cable to a better location or moving the router away from the ONT using a long Ethernet cable. This is the moment to plan Wi-Fi coverage for the whole home, not just the room nearest the fibre entry point.

Three practical points before the visit. First, if the property is rented, confirm with the landlord that the engineer can drill a small hole through the external wall. Most landlords are fine with this, but it is courteous to ask, and a few tenancy agreements specifically require permission. Second, your old copper line usually stays live for a short overlap, then ceases automatically once the FTTP service is activated, so you should not lose connectivity. Third, if your install is non-standard (long driveway, difficult cable route, listed building, no existing duct), Openreach may need a second visit and may charge an additional fee. Ask the provider to flag any non-standard work in advance.

Where your FTTP order is also a provider switch, the One Touch Switch process handles the cancellation of your old contract automatically. Over 2 million UK customers have used One Touch Switch since launch on 12 September 2024 (Ofcom, 2025b). You contact the new provider only; they manage the rest through the central TOTSCo messaging hub. Our step-by-step switching guide covers the full process.

Will your home phone still work after the upgrade?

Yes, but it will work in a different way. On a full fibre line, voice calls are delivered as digital voice over your broadband connection, not over a separate copper pair.

Digital voice (sometimes branded as BT Digital Voice, Sky Talk, Virgin Media VoIP, or similar) routes calls over the internet rather than the PSTN. In day-to-day use, you still pick up a phone and dial a number, and you can usually keep your existing landline number through a port. The handset normally plugs into the router rather than a wall socket. Inbound and outbound calls work as before for most households.

Two important caveats apply. First, during a power cut, your broadband and phone both go down unless you have a battery backup. On a traditional copper line, the phone usually still worked because the line carried its own power from the exchange. Providers offering digital voice are required to provide a battery backup solution free of charge to vulnerable customers and those who use the line for telecare devices. Second, telecare and personal alarm devices that were designed for analogue lines may need replacing or reconfiguring to work reliably on digital voice. This is why Openreach launched its nationwide Prove Telecare service in October 2025, giving providers a safe way to test telecare devices before migrating customers (Openreach, 2025a).

If anyone in the household uses a care alarm, a health pendant, a personal emergency response system, a security alarm linked to a phone line, or relies on a landline for medical reasons, raise this with the provider before placing the order. Our guide on switching broadband with care alarms covers the conversation in detail, and our broadband for pensioners page covers the wider considerations. Our digital voice guide explains how the new service works in practice.

For households that no longer use a landline, this part is simpler. Choose a broadband-only FTTP service where available. Many altnets and most Openreach retailers now default to broadband-only with digital voice as an optional add-on.

How do you choose the right provider on the Openreach network?

Start with Total Contract Value, contract terms and service fit, not brand familiarity.

Many UK providers sell broadband on the Openreach FTTP network: BT, Sky, TalkTalk, Vodafone, EE, Plusnet, NOW Broadband and Zen are among the most established, with a longer tail of value retailers and altnets-that-resell-Openreach also active. Their packages differ on monthly price, setup fee, contract length, included router, customer service ratings, and the size of the April price rise. For 2026, BT, EE and Plusnet apply £4 a month in April; Virgin Media (cable network) £4; TalkTalk £4; Sky £3; Vodafone £3.50. Several altnets, including Community Fibre, Zen, Cuckoo, YouFibre and Toob, commit to no mid-contract rise at all. Our in-contract price rises tracker documents the position for each major provider.

Three rules of thumb help you choose well. First, match the speed tier to your real usage. Most UK households do not need a gigabit line; a 100 to 300 Mbps FTTP package handles streaming, gaming, home working and several simultaneous video calls comfortably. Second, calculate Total Contract Value, not the headline monthly price. Add monthly price across the minimum term, plus setup, plus the April rise. Two packages at similar headline prices can differ by £80 to £150 across a 24-month term. Third, check whether the provider you are considering is signed up to the Ofcom Broadband Speeds Code of Practice (most are), which gives you a right to exit penalty-free if the minimum guaranteed speed cannot be delivered.

To start with provider rather than price, our compare by provider hub lists every major UK provider with their current contract lengths, technologies and price rises. If budget is the binding constraint, our pages on the broadband deals under £25 and broadband deals under £30 are sensible filters once you have a shortlist.

Copper versus Openreach full fibre: the trade-offs at a glance

The big gains are speed, upload performance and reliability. The trade-offs are installation timing, contract commitment, and the change in how voice works.

If you only browse lightly, your copper connection is cheap and stable, and your contract is still in force, there is no rule forcing an immediate switch this week. For most households, however, copper is now poor value once full fibre is available, and the same monthly spend buys a much stronger service.

What if you work from home or run a small business?

A fibre upgrade is usually easier to justify when your connection affects income, calls or customer service.

Remote workers tend to notice the upload speed improvement first. A 100 Mbps symmetric FTTP line handles two simultaneous Teams or Zoom calls without effort, where a 10 Mbps FTTC upload could not. Cloud backups, large file transfers and any work involving video uploads also improve dramatically. If your role depends on a stable connection, our broadband for home working guide covers the speed and reliability benchmarks.

For sole traders and micro-businesses, the upgrade case is even stronger. Copper-line faults rise as the network ages, and Openreach's stop-sell programme will end new copper provisioning in your area before the formal switch-off. If card payments, online bookings, EPOS or guest Wi-Fi depend on the line, the move to FTTP is a continuity decision as much as a performance one. Some very small operations are well served by residential FTTP; others benefit from business-grade service-level terms, static IP and a 4G or 5G backup connection. Our business broadband hub sets out where the line tends to sit.

If affordability is the constraint, households on Universal Credit, Pension Credit, Employment and Support Allowance, Jobseeker's Allowance or Income Support should check UK social tariffs. Several major providers offer FTTP social tariffs from £12 to £20 a month, and these are usually exempt from the April price rise.

Frequently asked questions

Do I have to use Openreach as my provider?

No. Openreach builds and maintains the wholesale fibre network, but you buy your broadband from a retail provider. Over 700 communications providers use the Openreach network, including BT, Sky, TalkTalk, Vodafone, EE, Plusnet, NOW Broadband and Zen. Your choice of retail provider determines price, customer service, router and contract terms.

Will switching from copper to fibre cause downtime?

Usually no, or very little. Your old copper line typically stays active for a short overlap and then ceases automatically once the FTTP service is activated. Do not cancel your old service manually unless your provider tells you to. Where One Touch Switch applies, the switching messages and timings are coordinated automatically.

Is full fibre always worth paying extra for?

In May 2026, FTTP is often the same price as or cheaper than the equivalent FTTC service, particularly from altnets and value retailers. It is worth comparing both for your address before assuming FTTP is a premium option. In many UK postcodes, the same monthly spend now buys an FTTP service that is two to ten times faster than the FTTC service it replaces.

Can I keep my landline number when moving to fibre?

Usually yes. Your provider should port the number from the old service to the new digital voice service. Confirm the number transfer before placing the order, particularly if you are switching providers as well as switching from copper to fibre. Cancelling the old service manually before the port completes can lose the number permanently.

What happens if Openreach fibre is available but my current provider does not sell it yet?

Compare alternatives at your address. Another retail provider on the Openreach network may already be selling FTTP at your postcode, or an altnet such as Community Fibre, YouFibre, Gigaclear or Toob may be live nearby. Use One Touch Switch to move to the new provider; you do not need permission from your current one.

Does One Touch Switch apply to copper to fibre upgrades?

Where you are switching to a different retail provider, One Touch Switch applies. Where you are upgrading from copper to FTTP with the same provider, the provider handles the migration internally. In either case, you only need to contact the new provider; the gaining provider manages the cancellation of the old service through the central TOTSCo messaging hub.
