Best Broadband Deals UK 2026
Full-fibre is now available to over 70% of UK homes — and it's often cheaper than slower copper. Switching at renewal can knock £15-£25 a month off your bill.
What you get
- Postcode checker shows what's available at your address
- Full-fibre (FTTP) speeds up to 1Gbps
- New-customer cashback up to £200
- Free routers, gift cards and bundled streaming
- Out-of-contract? You're paying 30-50% over the odds
How to choose
Check what fibre you can actually get
FTTP (full fibre) is best. FTTC (fibre to cabinet) tops out around 80Mbps. ADSL is yesterday's tech — only if nothing else is available.
Speed: be honest
Two streamers + occasional gaming need ~100Mbps. A houseful of 4K and remote work, 300Mbps+. Don't pay for 900Mbps unless you'll use it.
Watch the mid-contract hike
Most UK ISPs raise prices by CPI + 3.9% each April. Build that into your monthly cost comparison.
Don't auto-renew
Out-of-contract customers pay £15-£25 more per month than new-customer prices for identical service. Switch every contract.

FAQs
- Do I need a landline?
- Not for full-fibre. Most new FTTP deals are broadband-only.
- Will an engineer need to visit?
- Only if you're moving to a different technology (e.g. ADSL to FTTP).
- What speed do I need for 4K Netflix?
- 25Mbps per simultaneous 4K stream. 100Mbps is plenty for most UK homes.
