BT Fibre Broadband — Packages, Prices and Speeds (2026)

BT fibre broadband starts from around £24.99 per month for Fibre Essential (36 Mbps) and goes up to Full Fibre 900 (900 Mbps) from approximately £45–£55 per month. BT covers 95% of UK premises with part-fibre (FTTC) and around 65% with full fibre (FTTP) via the Openreach network, with a target of 85% FTTP coverage by December 2026.

BT Fibre Broadband Packages Explained

BT offers six main broadband tiers in 2026. Fibre Essential delivers average speeds of 36 Mbps and costs from £24.99 per month. Fibre 1 offers 50 Mbps, while Fibre 2 provides 67 Mbps from around £25.99 per month with a £70 reward card.

BT Full Fibre Coverage and Availability

BT's part-fibre (FTTC) network reaches roughly 95% of UK premises through Openreach, making it one of the most widely available providers in the country. Full fibre (FTTP) coverage stands at approximately 65% via Openreach as of early 2026, with thousands of homes being connected daily. Openreach aims to reach 25 million premises (around 85%) with FTTP by December 2026. If full fibre is not yet available at your address, BT's part-fibre deals (Fibre Essential, Fibre 1 and Fibre 2) still offer a solid upgrade over ADSL. BT also offers EE Mobile Backup on its Halo 3+ packages — if your fixed line goes down, the router switches to EE's 4G or 5G network automatically, keeping you online.

BT Fibre Speeds: Real-World Performance

Independent tests show BT Full Fibre 900 consistently delivers over 850 Mbps download over ethernet and around 400 Mbps over Wi-Fi in the same room via the Smart Hub 2. Upload speeds on the top residential tier sit at approximately 110 Mbps — adequate for most users but notably lower than the symmetrical uploads offered by altnet providers like Toob or Hyperoptic. On the part-fibre side, Fibre 2 typically delivers close to its 67 Mbps average, with upload speeds around 19 Mbps. BT's Stay Fast Guarantee means you can claim a £20 reward if speeds fall below the minimum guaranteed level, even during peak hours (8–10pm). For households needing consistent coverage across a large home, BT's Complete Wi-Fi add-on (£12 per month) includes Wi-Fi disc extenders and a £100 money-back guarantee if coverage does not improve.

BT Price Rises and Contract Terms

BT applies a fixed annual price increase each April. For 2026, the rise is £4 per month across all BT and EE broadband packages — following Ofcom's ban on opaque CPI+X percentage-based rises from January 2025. On a 24-month contract, that means your monthly bill increases by £4 from month 13 onwards. For example, Fibre 2 at £25.99 per month rises to £29.99 from April 2027. BT does offer occasional promotional deals with no price rise in the first year, so it pays to check current offers. If you want to avoid mid-contract increases entirely, alternative providers like Cuckoo and Toob guarantee fixed pricing for the full contract term.

BT Fibre Broadband FAQs

Can I get BT Full Fibre at my address?

BT Full Fibre (FTTP) covers approximately 65% of UK premises as of early 2026, with coverage expanding daily. Enter your postcode on CompareFibre or BT's website to check availability. If FTTP is not available, BT's part-fibre (FTTC) packages cover 95% of the UK.

What is BT's Stay Fast Guarantee?

BT guarantees a minimum download speed on Full Fibre packages. If your speed drops below this level, you can claim a £20 BT Reward Card. The guarantee covers speed to the hub, not Wi-Fi speeds in other rooms of your home.

How much does BT broadband cost per month?

BT fibre broadband starts from £24.99 per month for Fibre Essential (36 Mbps). Full Fibre packages range from around £29 to £55 per month depending on speed tier. All plans are subject to a £4 per month annual price rise each April.

Does BT have price rises during a contract?

Yes. BT applies a fixed £4 per month increase each April. Ofcom banned percentage-based CPI+X rises in January 2025, so all providers now state a clear pound amount. Some BT promotional deals delay the first rise until the second year of a 24-month contract.
