Cheapest Superfast Broadband Deals

If you just need reliable broadband for browsing and streaming, superfast deals from Plusnet, NOW Broadband and Vodafone start from around £18–20/month. These packages deliver 60–80 Mbps over the Openreach FTTC network — more than enough for a household of one or two people. Contract lengths are typically 18 or 24 months. Plusnet’s 66 Mbps plan often comes in at £19.99/month on a 24-month term with no setup fee, while Vodafone’s 73 Mbps Superfast 2 deal undercuts at around £18/month on an 18-month contract. NOW Broadband offers rolling monthly contracts from £20/month for greater flexibility. Before signing up, always check the annual mid-contract price rise amount — most providers add £3–4/month each April, which can significantly increase your total cost over two years.

Best Full Fibre Deals Under £25/Month

Full fibre (FTTP) has become remarkably affordable. Vodafone’s 150 Mbps FTTP plan starts at around £21/month, while Community Fibre offers 150 Mbps from £22/month in London. Virgin Media’s 362 Mbps M350 package is available from around £25/month on an 18-month deal. FTTP coverage now reaches 82% of UK premises, with over 11.56 million active connections — overtaking FTTC for the first time in Q3 2025. These plans deliver far more consistent speeds than part-fibre FTTC alternatives and offer substantially better upload performance, making them ideal for video calls, cloud backups and working from home. Prices have fallen sharply as competition between Openreach-based providers and alt-nets has increased.

Best Broadband for Speed

For households that need maximum bandwidth — gamers, streamers, large families or home workers uploading big files — gigabit packages offer the fastest speeds available. Hyperoptic’s 1 Gbps plan starts from around £30/month in supported buildings, making it one of the cheapest gigabit deals in the UK. Community Fibre’s 1 Gbps package costs roughly £32/month in London, while Virgin Media’s Gig1 plan is available from about £35/month. BT’s Full Fibre 900 costs more at around £40/month but includes BT’s Wi-Fi guarantee. The average UK broadband speed is now 157 Mbps, so a gigabit connection puts you well above the national average. See our broadband speeds guide to work out what speed your household actually needs before committing to the fastest tier.

How to Find the Best Deal for Your Address

Availability varies by postcode, so start by running a postcode check to see which providers serve your address. Compare the total contract cost, not just the headline monthly price — factor in setup fees (typically £0–30), the annual mid-contract price rise and any router delivery charge. Shorter 18-month contracts give flexibility; 24-month deals often have lower monthly rates. Check whether you’re still inside your minimum term, because switching before it ends usually means paying an early exit fee. If your contract has ended, you’re on a rolling deal and free to leave at any time. Use our guide on how to switch broadband to walk through the One Touch Switch process, which lets your new provider handle everything in around 10–14 working days.
