Cheapest Fibre Broadband Deals in 2026

The cheapest fibre broadband in the UK starts from £18 per month with NOW Broadband Super Fibre offering 36 Mbps. TalkTalk Fibre 65 costs £24 per month, Plusnet Fibre starts at £22, and Cuckoo offers 80 Mbps from £22 on a flexible rolling contract with no price rises. All deliver reliable fibre speeds suitable for everyday internet use.

Cheapest Fibre Deals Under £25 Per Month

Several providers offer fibre broadband below £25 per month in 2026. NOW Broadband leads with Super Fibre at 36 Mbps for £18 per month on a 12-month contract with no setup fee. Plusnet Unlimited Fibre delivers 36 Mbps from £22 per month with a small setup fee typically around £5. Cuckoo offers 80 Mbps for £22 per month on rolling monthly contracts — particularly good value as there are no price rises and no exit fees. TalkTalk Fibre 65 provides 67 Mbps from £24 per month on an 18-month deal. For slightly more, EE Fibre offers 36 Mbps from £24 per month with the added perk of data boosts on EE mobile plans. All these packages use the Openreach network, meaning availability is identical regardless of which provider you choose.

Budget Full-Fibre Options

Full-fibre FTTP packages are increasingly competitive on price. Hyperoptic offers 50 Mbps for £20 per month in connected buildings — often the cheapest true fibre deal available. Community Fibre provides 150 Mbps for £22 per month across London, outstanding value per megabit. BRSK delivers 100 Mbps from £24 per month in its growing network footprint. Shell Energy Broadband offers FTTP packages from £25 per month where available. These alt-net providers often undercut major ISPs because they own their own infrastructure and have lower wholesale costs. Full-fibre connections deliver more reliable speeds than part-fibre FTTC, with less variation between peak and off-peak performance. If FTTP is available at your address, it is usually worth choosing over a similarly-priced FTTC package.

How to Find the Cheapest Deal for Your Address

Broadband availability varies dramatically by postcode. Start by entering your postcode on comparison sites to see which providers and packages serve your address. The cheapest national deal may not be available locally. In areas with alt-net competition from providers like Toob, Trooli or Voneus, prices are often lower due to competitive pressure. Urban areas with multiple network operators consistently offer cheaper deals than rural locations served by only Openreach. Check whether your address has FTTP — if so, full-fibre packages often cost the same or less than older FTTC deals. Contact providers directly as well, since some deals are only available on their own websites and do not appear on comparison sites. BT and Virgin Media in particular sometimes offer web-exclusive prices.

Avoiding Cheap Deals That Cost More Long Term

A low monthly price can be misleading if other costs are high. Check the setup fee — a £0 per month saving is pointless if you pay £60 upfront. Factor in annual price rises; Sky adds £3 per month each April and Vodafone adds £3.50, so your £22 deal becomes £25.50 in year two. Consider the out-of-contract price, which can be 50 percent higher. Short 12-month contracts from NOW Broadband mean you renegotiate sooner, potentially getting another cheap deal. Longer 24-month contracts lock in a price but expose you to more price rises. The total contract cost — monthly fee times contract length, plus setup fee, plus price rises — is the only reliable comparison metric. A £24 per month deal with no rises and no setup fee often beats an £18 deal with £30 setup and £4 annual increases.
