Not all fibre broadband is the same. Most UK homes currently have FTTC (Fibre to the Cabinet) — fibre runs from the telephone exchange to a street cabinet, then copper wire from the cabinet to your home. This is what most providers advertise as 'fibre' but delivers speeds of only 30-80Mbps. Full fibre (FTTP — Fibre to the Premises) runs optical fibre cable all the way into your home, delivering speeds of 100Mbps to 1Gbps+ with significantly better reliability. In 2026, full fibre is available to approximately 60-70% of UK premises and growing rapidly.
Key Facts 2026
FTTC ('standard fibre'): 30-80Mbps download | FTTP (full fibre): 100Mbps-1Gbps+ | UK full fibre coverage: ~60-70% of premises | Check availability: openreach.com/fibre-checker

Is Full Fibre Worth Upgrading To? UK 2026
Household Profile
Upgrade Recommended?
Reason
Single user, light browsing and email
No — FTTC is fine
Current 30-80Mbps more than enough
Couple, HD streaming and some WFH
Maybe — if upload is a bottleneck
FTTP solves slow upload speeds for video calls
Family of 4 with multiple devices, 4K TV
Yes — strong recommendation
FTTP eliminates buffering and connection drops
Gamer or streamer
Yes
Lower latency and more stable connection on full fibre
Multiple WFH in same household
Yes — essential
Upload speed crucial; FTTC upload often inadequate
Rural area with poor copper speeds
Check FTTP availability
If FTTP is available, even basic packages beat poor FTTC
Who Provides Full Fibre UK 2026?
Full fibre rollout is accelerating across the UK in 2026. The main infrastructure builders: Openreach (BT Group) — the largest; building full fibre to ~25 million premises by 2026; Virgin Media O2 (cable network — not FTTP but similar speeds); and alternative network providers (altnets) including CityFibre (reaches over 8 million premises), Hyperoptic (urban flats), Toob (South of England), MS3 (Wales/Midlands), and Community Fibre (London). Many ISPs including Sky, BT, Vodafone, TalkTalk, and Plusnet use Openreach's full fibre infrastructure. Check availability at openreach.com/fibre-checker for your postcode.
Switching to Full Fibre Broadband UK — What to Expect
Check availability at openreach.com/fibre-checker or on any major ISP's website using your postcode
Engineer visit required — FTTP installation requires an Openreach engineer to install a new optical fibre termination point (ONT) in your home; typically takes 2-4 hours
No disruption during installation — most installations run alongside existing phone/broadband with a quick switchover at the end
New router required — your existing FTTC router typically won't work with FTTP; the ISP will supply a new one
Contract considerations — if you're in contract with your current provider, check early termination fees before switching; if your current provider offers FTTP on the same infrastructure, switching with them avoids ETFs
Compare on switching — prices vary significantly; MoneySuperMarket and Uswitch compare FTTP deals by postcode
Frequently Asked Questions
What is the difference between FTTC and FTTP broadband UK?
FTTC (Fibre to the Cabinet) runs optical fibre from the telephone exchange to a green street cabinet, then uses existing copper telephone wires from the cabinet to your home. This limits speeds to 30-80Mbps and degrades with distance. FTTP (Fibre to the Premises / full fibre) runs optical fibre all the way into your home, delivering 100Mbps-1Gbps+ with consistent speeds regardless of distance from the exchange.
Is full fibre broadband available in my area UK?
Check at openreach.com/fibre-checker by entering your postcode. Alternatively, most major ISP websites (BT, Sky, Vodafone) will tell you the fastest available speed when you enter your postcode during a quote. In April 2026, full fibre is available to approximately 60-70% of UK premises and coverage is expanding rapidly.
Do I need a new router for full fibre UK?
Yes — full fibre connections require a new router compatible with the FTTP technology. Your ISP will provide a new router as part of the installation. The Openreach engineer installs an Optical Network Terminal (ONT) box — the FTTP equivalent of a phone socket — and your new router connects to this. You don't need to buy a separate router unless you want to upgrade beyond the ISP-supplied one.
Can I keep my phone number when switching broadband UK?
Yes — you can keep your home phone number when switching broadband providers. If you are switching from BT or an Openreach-based ISP, your number transfers automatically. If switching from or to Virgin Media (a separate network), you may need to arrange a number port. Inform your new provider you want to keep your number when signing up.
