UK home broadband is delivered over four fundamentally different technologies in 2026: full fibre to the premises (FTTP), fibre to the cabinet plus copper (FTTC), Virgin Media's hybrid fibre-coaxial cable (HFC), and 4G or 5G mobile-network home broadband. Each has materially different download speed limits, upload speed profiles, reliability characteristics, footprint coverage, and per-month costs, and the right answer for your household depends on what is built at your specific address rather than which technology is theoretically best. Full fibre is the fastest and most consistent at residential prices, with Openreach FTTP now at approximately 85 percent of UK premises by end of 2026 and altnet operators (CityFibre, Hyperoptic, Community Fibre, Gigaclear, YouFibre, BeFibre, Toob, Zzoomm and others) adding further coverage on top. FTTC is the most widely available at approximately 95 percent of UK premises but the medium-term picture is changing rapidly because the PSTN switch-off scheduled 31 January 2027 ends the copper telephone line that FTTC depends on, with Openreach actively migrating customers to FTTP or digital voice over broadband. Virgin Media HFC cable covers approximately 52 percent of UK premises with strong download speeds (Gig1 at 1,130 Mbps is the UK's fastest widely-available standard download tier) and the Nexfibre FTTP joint venture (acquired fully by Virgin Media O2 in February 2026) extends symmetric multi-gigabit to approximately 5 million premises. 4G home broadband is widespread; 5G home broadband has accelerated since the VodafoneThree merger completed 31 May 2025 created the UK's largest mobile network by customer count and materially expanded 5G capacity. This guide explains each technology in 2026 terms, when each is the right choice, and how to check what is actually available at your address.
Full fibre (FTTP) is the best technology for almost every household in 2026 if it is available at your address: fastest, most consistent, symmetric upload, no copper-degradation issues, and unaffected by the 31 January 2027 PSTN switch-off. Cable (Virgin Media HFC) delivers the UK's fastest widely-available standard download tier (Gig1 at 1,130 Mbps) but with asymmetric upload (52 Mbps on Gig1) and is restricted to the approximately 52 percent of UK premises Virgin Media has built; the Nexfibre FTTP joint venture (acquired by Virgin Media O2 February 2026) extends symmetric multi-gigabit to approximately 5 million premises. FTTC remains widely available (approximately 95 percent UK coverage) and competitively priced for light-to-moderate household use but is materially slower than FTTP or cable and is being actively superseded as Openreach drives the FTTP rollout ahead of the PSTN switch-off. 4G and 5G home broadband are the right choice for households where fixed-line options are limited, for renters who want flexibility, and for short-term setups; post-VodafoneThree-merger 5G coverage and capacity have improved materially across the UK. Run a postcode check to see what is actually built at your address before deciding which technology to choose.
Fibre-optic cable from the exchange directly into your home, terminating at an Optical Network Terminal (ONT). Speeds 100 Mbps to 3,000 Mbps (Community Fibre 3 Gig is UK's fastest residential tier). Symmetric or near-symmetric upload on most plans. Approximately 85 percent UK coverage by end 2026 (Openreach plus altnets). The right choice when available.
Fibre to the green street cabinet, then existing copper telephone line to your home. Speeds 30 Mbps to 80 Mbps; upload 10 to 20 Mbps; performance drops with cable distance from the cabinet. Approximately 95 percent UK coverage but receding ahead of the 31 January 2027 PSTN switch-off. Sensible default for light-to-moderate use where FTTP is not yet available.
Coaxial cable to your home with fibre backhaul to the local node. Speeds 132 Mbps to 1,130 Mbps on HFC; upload asymmetric (52 Mbps on Gig1). Plus Nexfibre FTTP at up to 2,000 Mbps symmetric on Gig2 across approximately 5 million premises. Approximately 52 percent UK coverage on HFC plus the Nexfibre footprint. Strong for download-heavy households where FTTP not yet available.
Wireless connection from a 4G or 5G mast to an indoor router. 4G typical 10 to 50 Mbps; 5G typical 100 to 300 Mbps practical. Setup is near-instant; rolling 30-day contracts widely available. Right choice for renters, short-term setups, and households with limited fixed-line options. Post-VodafoneThree-merger 5G coverage (31 May 2025) is materially improved.

See live deals at your postcodeThe five-row matrix below summarises the four UK home broadband delivery technologies on speed, upload, reliability, best-fit use, and 2026 UK coverage. 4G and 5G are listed separately because their speed and coverage characteristics are materially different despite both being mobile-network home broadband.
| Technology | How it works | Typical speeds | Upload | Reliability | Best for | UK coverage 2026 |
|---|---|---|---|---|---|---|
| FTTP (full fibre) | Fibre-optic cable direct to your premises terminating at an ONT | 100 Mbps to 3,000 Mbps; Community Fibre 3 Gig is UK's fastest residential symmetric tier | Symmetric or near-symmetric on most altnet plans (e.g. 1,000 Mbps up on 1 Gig); 115 Mbps up on Openreach FTTP gigabit (asymmetric) | Very high; not affected by line distance, electrical interference, or wet weather | Heavy streaming, gaming, home working, video calls, multi-user households, large file uploads, future-proofing | ~85% (Openreach plus altnets, end 2026) |
| FTTC | Fibre to the green street cabinet, then existing copper telephone line to your home | 30 to 80 Mbps download; varies with distance from cabinet | 10 to 20 Mbps | Moderate; performance degrades over longer copper runs and in wet weather | Light-to-moderate use: browsing, email, single-screen HD streaming, where FTTP not yet built | ~95% but receding (PSTN switch-off 31 January 2027) |
| Cable (Virgin Media HFC) | Coaxial cable to your home with fibre backhaul to the local Virgin Media node | 132 to 1,130 Mbps download depending on package | Asymmetric: 20 to 52 Mbps; Gig1 caps at 52 Mbps up | Generally good but shared local bandwidth can cause peak-time slowdowns | High-download households where FTTP not yet available; Volt mobile-bundle households | ~52% (Virgin Media HFC footprint) |
| Nexfibre FTTP (Virgin Media) | XGS-PON FTTP from Virgin Media O2 retailing on the Nexfibre joint venture (acquired Feb 2026) | Up to 2,000 Mbps symmetric on Gig2 | Symmetric (2,000 Mbps up on Gig2) | Very high; FTTP characteristics | Multi-gigabit households on Virgin Media platform; Volt customers wanting symmetric | ~5 million premises and growing |
| 4G home broadband | Wireless from a 4G mobile mast to an indoor router with SIM card | 10 to 50 Mbps practical; depends on signal and congestion | Typically 5 to 15 Mbps | Variable; affected by weather, building materials, and distance from mast | Rural areas, renters, temporary setups, where fixed-line not in scope | Widespread outdoor coverage; indoor varies significantly |
| 5G home broadband | Wireless from a 5G mast to a 5G-capable indoor router | 100 to 300 Mbps practical (theoretical peak much higher) | 10 to 50 Mbps | Good where signal is strong but range is shorter than 4G | Urban and suburban households wanting fast wireless without fixed install | Concentrated in towns and cities; expanding post-VodafoneThree merger |
Full fibre, technically fibre to the premises (FTTP), runs a fibre-optic cable from the exchange directly into your home. Because the entire route is glass fibre rather than copper, data travels as pulses of light rather than electrical signals, and the connection is therefore not affected by line length, electrical interference, or wet weather. This makes FTTP the most consistent broadband technology available in the UK in 2026, with download speed determined by the package you buy rather than by physical line characteristics.
UK FTTP retail covers a wide range of speeds and providers in 2026. Openreach FTTP retailers (BT, Sky, Vodafone, EE, TalkTalk, Plusnet, NOW, Zen, Cuckoo and many smaller providers) typically offer plans from 100 Mbps to 900 Mbps, with selected areas served by flagship multi-gigabit tiers (Sky 2.5 Gigafast+ at 2,500 Mbps symmetric in selected Openreach FTTP areas, Vodafone Pro II Symmetric Gigafast at 2,300 Mbps symmetric). Altnet operators running their own FTTP networks include Hyperoptic (UK-wide MDU-focused, up to 2,000 Mbps symmetric Hyperfast 2 Gig), Community Fibre (London-only, up to 3,000 Mbps symmetric 3 Gig, the UK's fastest residential tier), Gigaclear (rural-focused), YouFibre (with Brsk migrating in by 16 March 2026), BeFibre (now part of the Zzoomm brand integration of February 2026), Toob, 4th Utility, Connect Fibre, Fibrus (Northern Ireland), Ogi (Wales), Quickline (rural Yorkshire), Trooli (Kent and South East), Truespeed (South West), WightFibre (Isle of Wight), and Zzoomm (the FullFibre Group brand serving 110 plus UK market towns). Virgin Media O2 retails Nexfibre FTTP at up to 2,000 Mbps symmetric on Gig2 across approximately 5 million premises following the February 2026 full acquisition of the Nexfibre joint venture from its previous Liberty Global plus InfraVia structure.
The single biggest practical advantage of FTTP over other technologies is upload speed. On a typical Openreach FTTC line at 80 Mbps download, upload is approximately 20 Mbps, and uploading a 5 GB video file takes around 30 minutes. On a typical Openreach FTTP gigabit line at 900 Mbps download, upload is approximately 115 Mbps, and the same upload finishes in under five minutes. On an altnet FTTP gigabit at 1,000 Mbps symmetric (Hyperoptic, Community Fibre, YouFibre, Gigaclear, Toob, etc.), upload is the full 1,000 Mbps and the same file uploads in approximately 40 seconds. For households who upload large files, run cloud backups, work in video production, run home servers, or use video calls intensively, the symmetric-upload advantage of altnet FTTP is the most concrete reason to choose an altnet over Openreach or Virgin Media at the same headline download speed.
Installation usually involves an Openreach or altnet engineer running fibre cable from the nearest distribution point into your property and fitting an Optical Network Terminal (ONT) inside the home. The router connects to the ONT via Ethernet rather than to a master phone socket as on FTTC. Installation is typically free on a new contract though the process can take two to four weeks from order to activation, longer in some flat blocks where wayleave permission from a freeholder or management company may be needed first. The Automatic Compensation scheme pays £6.10 per day for activation delays beyond the agreed start date.
The main 2026 limitation of FTTP remains availability. While Openreach FTTP coverage is approximately 85 percent of UK premises by end of 2026 (up from approximately 60 percent at end of 2024), and altnet operators are adding several million premises on top, full fibre has not yet reached every UK address. Rural areas in particular may face longer waits, though projects like Project Gigabit (the UK government's £5 billion programme to bring gigabit-capable broadband to hard-to-reach areas) are accelerating rural rollout via altnets including Gigaclear, Fibrus, and Quickline. You can check whether FTTP is live at your postcode using the tools described in the availability section below.
FTTC stands for fibre to the cabinet. Fibre-optic cable runs from the exchange to the green street cabinet in your neighbourhood, but the final stretch (the so-called "last mile") from the cabinet to your home uses the existing copper telephone line. This last-mile copper is the bottleneck: the further your property is from the cabinet, the more signal attenuation occurs over the copper run, and the slower your connection will be.
Typical UK FTTC download speeds range from approximately 30 Mbps to 80 Mbps in 2026, though Ofcom data shows that average speeds for FTTC customers tend to sit around 50 Mbps in practice. Upload speeds are much lower than download, usually 10 to 20 Mbps. If your home is more than approximately 400 metres of copper cable from the cabinet, you may see materially lower performance than the headline figures: Openreach estimates that for every 100 metres of copper beyond the cabinet, speeds can drop by approximately 1.5 to 2 Mbps download. Internal wiring quality, the age of your master socket, micro-filter condition, and whether the in-home wiring runs near electrical sources all affect performance further.
FTTC's main 2026 strength is availability. It covers approximately 95 percent of UK premises, making it the default superfast option in many areas where FTTP has not yet been built. Pricing tends to be competitive because multiple major retailers (BT, Sky, TalkTalk, Vodafone, EE, Plusnet, NOW, Zen) resell Openreach FTTC under their own brand names with monthly prices typically ranging from approximately £25 to £35 per month for the headline tier. If you are on a basic ADSL connection (the older copper-only technology that still serves a small percentage of UK premises in remote rural areas) and FTTP has not reached you yet, upgrading to FTTC is usually a straightforward improvement.
Beyond the PSTN switch-off transition, FTTC's other limitation is that copper lines are inherently susceptible to interference and degradation over time. Performance can dip during heavy rain, ageing copper in older properties tends to underperform, and FTTC simply cannot scale to the gigabit speeds that FTTP and cable can deliver: an FTTC line is physically capped by the copper layer at approximately 80 Mbps regardless of what speed your provider sells. As multi-device households grow (smart TVs, multiple streaming subscriptions, work-from-home video calls, gaming consoles, smart-home devices), FTTC's headroom is increasingly tight.
Cable broadband in the UK is delivered exclusively over the Virgin Media O2 network, which runs hybrid fibre-coaxial (HFC) infrastructure: fibre runs from the local exchange to a Virgin Media street node, and from that node, coaxial cable carries the signal the rest of the way to your property. Because coaxial cable has materially more bandwidth capacity than the twisted-pair copper telephone line that FTTC uses, cable can deliver significantly faster download speeds than FTTC, with packages ranging from approximately 132 Mbps (M125 entry tier) up to 1,130 Mbps (Gig1, the UK's fastest widely-available standard download tier).
The HFC tier ladder in 2026 runs M125 (132 Mbps), M250 (264 Mbps), M350 (362 Mbps), M500 (516 Mbps), and Gig1 (1,130 Mbps download). Upload speeds on HFC are structurally asymmetric: Gig1 caps at 52 Mbps upload despite delivering 1,130 Mbps download. This is because the HFC architecture allocates more spectrum to downstream than to upstream, reflecting the historical assumption that household traffic is predominantly download-led. For most household use (browsing, streaming, video calls), this asymmetry is invisible; for upload-heavy use (cloud backups, large file uploads, video production), it is genuinely a constraint.
Virgin Media O2 acquired Nexfibre fully in February 2026 from the previous Liberty Global plus InfraVia joint venture structure. Nexfibre is XGS-PON FTTP (the same fibre technology used by Hyperoptic, Community Fibre, CityFibre, and the latest Openreach FTTP) and now covers approximately 5 million UK premises with continued buildout. Virgin Media retails on Nexfibre via the Gig2 tier at 2,000 Mbps symmetric (the only true symmetric multi-gigabit tier on the Virgin Media platform), and Volt customers benefit from the same Nexfibre symmetric speeds where available. At the household level, this means Virgin Media's network proposition in 2026 is effectively two networks: HFC cable in the original ~52 percent footprint with strong download speeds but asymmetric upload; plus Nexfibre FTTP in approximately 5 million premises with full symmetric multi-gigabit.
Cable does not require a telephone line, so you will not pay a line rental charge. Installation involves running coaxial cable into your property if one is not already present (which can be more disruptive than an Openreach or altnet FTTP install in some properties), or activating the existing Virgin Media line if cable was previously installed at the address. Installation is usually included with a new contract. Virgin Media supplies the Hub 5 (Wi-Fi 6) router as standard on most HFC tiers, the Hub 5x for Gig2 XGS-PON Nexfibre customers, and older Hub 3 or Hub 4 still in some legacy field installations.
Cable's main 2026 limitations are footprint and the asymmetric upload structure. Outside the approximately 52 percent of UK premises in the HFC footprint plus the 5 million Nexfibre premises, cable is simply not in scope and the comparison ends there. The HFC asymmetric upload also makes cable less suitable for video conferencing households or households who routinely upload large files, where Openreach FTTP at 115 Mbps up or altnet FTTP at full symmetric upload is materially better. Virgin Media's contract lengths in 2026 are 18-month standard on most consumer plans and 24-month on Volt bundles; out-of-contract pricing increases meaningfully so worth checking what the monthly cost reverts to after any introductory period ends.
4G and 5G home broadband replace the physical cable into your home with a wireless connection to a nearby mobile mast. The provider supplies a plug-in router (sometimes called a hub or home gateway) that contains a SIM card and connects to the 4G or 5G mobile network. Your devices then connect to this router over Wi-Fi or Ethernet exactly as they would on a fixed-line connection, and from your devices' perspective the experience is largely the same as fixed-line broadband. The 2026 UK proposition has been materially reshaped by the VodafoneThree merger that completed on 31 May 2025 and created the UK's largest mobile network by customer count, which has improved 5G coverage and capacity across the merged Vodafone-and-Three footprint and increased competitive pressure on EE and O2 in the home-broadband-over-mobile space.
For 4G home broadband, real-world download speeds usually fall between 10 and 50 Mbps, depending on signal strength, distance from the mast, and how many other users share the cell at the time of day you are using it. This is enough for general browsing, email, standard-definition or single-screen HD streaming, video calls, and most day-to-day household use, but may struggle with simultaneous HD streams across multiple devices or large downloads. Upload speeds on 4G home broadband typically sit at 5 to 15 Mbps. Latency on 4G is materially higher than on fixed-line fibre (typically 30 to 60 milliseconds vs 5 to 15 milliseconds on FTTP), which can affect competitive online gaming, real-time voice calls, and time-sensitive applications. 4G home broadband typical providers in 2026 include Three (the Three 5G Hub also operates on 4G in non-5G areas), EE 4GEE Home Router, Vodafone GigaCube 4G, and O2 Home Wireless. Most 4G home plans are available on rolling 30-day contracts which makes 4G home broadband a strong fit for renters, students, and households in temporary accommodation.
For 5G home broadband, real-world speeds are significantly faster: typically 100 to 300 Mbps practical in areas with strong mid-band 5G coverage, with some users reporting peaks above 500 Mbps in ideal conditions. Upload on 5G home broadband typically sits at 10 to 50 Mbps, materially better than 4G but still well below altnet FTTP symmetric upload. Latency on 5G is approximately 15 to 30 milliseconds, much closer to fixed-line fibre than 4G. The trade-off is that 5G signals have a shorter range than 4G and are more easily blocked by walls and buildings, so indoor performance depends heavily on the placement of your router and the proximity of the nearest 5G mast. 5G home broadband 2026 providers include Three 5G Hub (the most established UK proposition), EE 5G Smart Hub Plus (with the most extensive UK 5G mast footprint via BT Group), Vodafone GigaCube 5G (now benefiting from the merged VodafoneThree network), and O2 5G Home Broadband (via Virgin Media O2).
Both 4G and 5G home broadband are particularly attractive for renters, people in temporary accommodation, rural households where fixed-line speeds are poor, and households who need to be online quickly without waiting two to four weeks for a fixed-line install (4G and 5G hubs can be online within minutes of plugging in). Many 4G and 5G home broadband plans are available on 30-day rolling contracts giving flexibility to cancel without penalty, though lower per-month pricing is available on 12-month or 24-month plans. Setup is near-instant: plug in the router, wait for it to connect to the network, and you are online. No engineer visit required.
The main 2026 limitations of 4G and 5G home broadband are inherent to wireless technology. Speeds can fluctuate throughout the day as the mobile cell becomes congested at peak times (early evening typically the worst), adverse weather can degrade signal, and indoor performance depends on the building structure: brick walls, double-glazing with metallic film, and reinforced concrete all attenuate the signal materially. Latency, while improved on 5G, remains higher than fixed-line fibre and can affect competitive online gaming or real-time professional applications. Data caps still apply on some plans (typically the cheaper tiers), although unlimited data plans are increasingly common. Before committing, check the signal strength at your specific address using the provider's coverage checker, and take advantage of any trial period or 14-day cooling-off window to verify real-world performance.
Availability varies street by street and even building by building in the same postcode, so checking your specific address is essential. In 2026, the four main checks below cover the full UK broadband technology picture.
If none of these checks show a suitable fixed-line option at your address, a 4G or 5G home broadband plan can bridge the gap until further fixed-line rollout reaches your area. The four UK mobile networks (BT/EE, VodafoneThree, O2 via Virgin Media O2) all offer mobile-network home broadband with 4G or 5G hubs that are typically online within minutes of plugging in. For urgent needs, mobile-network home broadband can also work as a temporary backup while you wait for a fixed-line install.
The right technology choice depends on what is actually available at your address rather than which technology is theoretically best. Use the framework below as a starting point, then verify with a postcode check.

Full fibre, technically fibre to the premises (FTTP), runs a fibre-optic cable from the exchange directly into your home, with the entire route being glass fibre. FTTC stands for fibre to the cabinet: fibre runs from the exchange to the green street cabinet in your neighbourhood, but the final stretch from the cabinet to your home uses the existing copper telephone line. This last-mile copper is the bottleneck on FTTC and the reason FTTP is materially faster, more consistent, and more future-proof. Typical FTTP speeds in 2026 range from 100 Mbps to 3,000 Mbps with symmetric or near-symmetric upload on most plans. Typical FTTC speeds are 30 to 80 Mbps download with 10 to 20 Mbps upload, and performance drops the further your home is from the street cabinet. FTTP is unaffected by line distance, electrical interference, or wet weather; FTTC is sensitive to all three. As Openreach completes the FTTP rollout (approximately 85 percent UK coverage by end of 2026, target near-universal by end of 2030) and the PSTN switch-off on 31 January 2027 ends the copper telephone line that FTTC depends on, FTTC is being phased out as the standard UK home broadband technology. In 2026, choose FTTP if available; choose FTTC only if FTTP is not yet built at your address and you cannot wait.
For most households in 2026, yes. The price gap between FTTC and entry-level FTTP packages has narrowed considerably, and in many cases FTTP at 100 to 150 Mbps is now comparable in monthly cost to FTTC at 67 to 80 Mbps. Where FTTC and FTTP are both retailed by the same provider on Openreach (BT, Sky, EE, TalkTalk, Vodafone, Plusnet, NOW, Zen and others), the monthly price difference is often under £5 per month for materially better service. Altnet FTTP (Hyperoptic, Community Fibre, YouFibre, Gigaclear, Toob, Zzoomm and others) often prices below equivalent Openreach FTTC. The genuine practical gains from FTTP are consistency (no line-distance degradation, no weather sensitivity), upload speed (up to 1,000 Mbps symmetric on altnet FTTP gigabit vs 20 Mbps on FTTC), latency (5 to 15 milliseconds on FTTP vs 25 to 50 milliseconds on FTTC), future-proofing (FTTP scales to multi-gigabit speeds; FTTC is physically capped near 80 Mbps regardless of provider), and freedom from the 31 January 2027 PSTN switch-off transition. If you work from home, join video calls regularly, have multiple people streaming simultaneously, or upload large files, the difference is materially noticeable. For a single user doing only light browsing on a single device, FTTC may still be sufficient short-term, but FTTP is the better long-term choice when available.
Often yes, but it depends on whether the building has been connected. Some newer developments are pre-wired for FTTP at construction, in which case FTTP is typically available immediately on a new contract. In older blocks, the provider (Openreach or an altnet such as Hyperoptic, Community Fibre, or others) may need wayleave permission from the freeholder or management company before installing fibre into the building's main intake point and running in-building cabling to individual flats. Wayleave negotiation can cause delays of weeks to months, so it is worth checking with your building manager and the relevant provider early in the process. Hyperoptic specialises in multi-dwelling units (blocks of flats) across 50 plus UK cities and towns, with deep MDU specialism that other altnets typically do not match. Community Fibre operates extensively across Greater London including via council partnerships (Hackney, Tower Hamlets, Lewisham, Southwark, Lambeth, Newham, Wandsworth, Camden, Islington and others) where the council acts as freeholder and grants estate-wide wayleave for fibre installation. Once a flat block has FTTP installed by any provider, every flat in the block can typically order service. If your block does not yet have FTTP, you can register interest on Openreach's site or with relevant altnets to flag demand to the freeholder.
In areas with strong mid-band 5G coverage, the download speeds can be comparable to mid-tier fibre packages: 100 to 300 Mbps practical with peaks above 500 Mbps in ideal conditions. However, 5G is more susceptible to fluctuations than fibre because the connection runs over the air to a mobile mast: signal strength, network congestion at peak hours, weather, and physical obstructions (walls, double-glazing, reinforced concrete) all affect performance. Latency is generally higher than on a wired fibre connection (15 to 30 milliseconds on 5G vs 5 to 15 milliseconds on FTTP), which may affect time-sensitive applications such as competitive online gaming or real-time professional voice or video. Indoor performance varies materially with building structure: brick walls and metallic-film double-glazing both attenuate 5G signal, sometimes to the point where the 5G hub falls back to 4G or struggles to maintain a usable connection. For general use (browsing, streaming, video calls, working from home), 5G home broadband can be a strong fixed-line alternative where 5G coverage at your specific address is genuinely strong. Run a coverage check with the provider, place the hub near a window or external wall facing the nearest mast, and take advantage of any trial period or 14-day cooling-off window to verify real-world performance before committing. Fibre remains more predictable than 5G if available, but 5G in 2026 is materially better than it was in 2024 thanks to the post-VodafoneThree-merger network expansion.
FTTC speeds are heavily influenced by the length and quality of the copper line between the green street cabinet and your property. Openreach estimates that for every 100 metres of copper beyond the cabinet, download speeds can drop by approximately 1.5 to 2 Mbps. If your home is 400 metres or more from the cabinet on the copper run, your achievable speed may be materially below the headline 80 Mbps maximum. Internal wiring quality also plays a role: ageing master sockets, the position of the master socket relative to where you place the router, micro-filter condition, in-home extension wiring running near electrical sources, and the age of the copper drop-wire from the pole or pavement into the property all affect performance. Wet weather can degrade copper performance further, particularly if the drop-wire has degraded insulation. If your speed is consistently well below what was estimated at sign-up, contact your provider and ask them to investigate. They may be able to send an engineer to check the line, replace the drop-wire if it has degraded, or in some cases re-provision the line with different DSL parameters that are better matched to your line characteristics. In the medium term, the only real solution to slow FTTC is to upgrade to FTTP when it becomes available at your address.
Not necessarily in 2026. FTTP, cable (Virgin Media HFC and Nexfibre), and 4G or 5G home broadband all work without a traditional copper phone line. FTTC does still use the copper telephone line for the data carrier from the green street cabinet to your home, but most providers now offer broadband-only packages without a landline voice service (you have the broadband over the line but no telephone phone number or voice service active). If you rarely use a landline phone, removing the voice service can reduce your monthly bill by approximately £5 to £10 per month depending on provider and plan. After the 31 January 2027 PSTN switch-off, the traditional copper landline voice service will no longer exist for any UK premises, and any landline phone service will run as digital voice over your broadband connection. Vulnerable customers who depend on a landline for medical alarms, care-line services, or who have accessibility needs should talk to their provider about the digital voice migration plan well ahead of the 2027 deadline; your provider should contact you proactively but it is worth checking if you have not heard from them. Ofcom has issued regulatory guidance on the migration including a £23.8 million fine to Virgin Media in December 2025 over failures affecting vulnerable landline customers during the migration.
The Public Switched Telephone Network (PSTN) switch-off scheduled for 31 January 2027 ends the underlying copper voice service that the UK telephone network has run on for over a century. For FTTC broadband customers specifically, the practical impact depends on what services you currently have. If you have FTTC plus a copper landline phone, the landline voice service moves to digital voice over your broadband connection: your provider will supply a new digital voice adapter (often built into a new router) and your existing phone handset plugs into the adapter rather than into a wall socket. Your broadband itself (the FTTC layer) may continue on the still-active broadband bearer that Openreach maintains over the copper for some time after the voice PSTN switches off, or you may be migrated to FTTP if FTTP is now available at your address. If you have FTTC and broadband only (no landline phone), the practical impact on you is smaller: your broadband continues, and the PSTN switch-off affects you only insofar as Openreach is actively migrating customers to FTTP where available to reduce the long-term operational burden of maintaining copper. In the medium term, FTTP will replace FTTC as the standard UK home broadband technology; for new contracts in 2026, we recommend choosing FTTP if available at your address rather than committing to a longer-term FTTC contract that may need to be re-provisioned during the term. Vulnerable customers with care alarms, medical pendants, or accessibility-dependent landline services should engage proactively with their provider on the digital voice migration; do not wait until late 2026 to address this.
The fastest single-source check in 2026 is the Ofcom coverage checker at ofcom.org.uk, which gives an overview of fixed and mobile broadband options at your postcode in a single view, drawing on data from Openreach, Virgin Media, the major altnets, and the four UK mobile networks. For more detail, run the Openreach fibre availability checker at openreach.com (covers FTTP and FTTC for the BT, Sky, EE, TalkTalk, Vodafone, Plusnet, NOW, Zen and other Openreach retailer footprint, approximately 95 percent of UK premises), the Virgin Media availability checker at virginmedia.com (HFC cable plus Nexfibre FTTP), and the websites of any altnets known to operate in your area (Hyperoptic, Community Fibre, CityFibre, Gigaclear, YouFibre, BeFibre, Toob, 4th Utility, Connect Fibre, Fibrus, Ogi, Quickline, Trooli, Truespeed, WightFibre, Zzoomm and others). Or use our independent postcode comparison at broadbandswitch.uk/compare which combines results from 35 plus UK providers in a single view with live pricing, contract length, and feature filters. If you live in a flat or apartment block, the in-building infrastructure can vary even within a single street: ask your building manager which providers have laid fibre into the block, and check provider sites directly using the full address rather than just the postcode.
