Stop overpaying for UK broadband: the £34.50 average and how to beat it

The average UK household pays around £34.50 a month for broadband. Entry-level full fibre from smaller networks starts around £17-£23 for 100-160 Mbit/s, a typical 150 Mbit/s plan sits in the low-to-mid £20s, and gigabit deals land between £25 and £40 for new customers.

Ofcom's 2026 pricing report found prices fell about 6% in real terms in the year to September 2025 — but those falls go to switchers. Around 28% of customers are out of contract and paying roughly £7 to £9 a month more than they need to. That is £84 to £108 a year for doing nothing.

Since January 2025 Ofcom has banned percentage and inflation-linked mid-contract rises on new contracts: any increase must be stated in pounds and pence when you sign. In April 2026 most big providers applied a fixed rise of £3 to £4 a month.

Add every monthly payment across the contract, add the setup or activation fee, then divide by the number of months. A £27 deal with a £35 setup fee over 24 months is really £28.46 a month. Include any stated mid-contract rise in the total.

Then divide the true monthly cost by the average download speed to get cost per Mbps. That is the only fair way to compare a £22 150 Mbit/s deal against a £35 gigabit one — and it is what the broadband calculator does for you.

Cashback and reward cards are real money but only if you claim them, and gift-card cashback usually needs claiming inside a narrow window after activation.

A 4K stream needs roughly 25 Mbit/s, video calls far less, and most homes are comfortable well below gigabit. Speed only matters when several people are doing heavy things at once or you routinely move very large files.

If your Wi-Fi is the bottleneck — thick walls, a router in a cupboard, an ageing laptop — a faster line changes nothing. Move the router into the open, use the 5 GHz band nearby, and try a mesh unit before paying more every month.

Diary the end of your minimum term; providers must tell you when it is approaching and what you would pay by staying. Compare across providers, then call your current one and say you are leaving — retention offers are often as good as the new-customer deals.

If you do move, most UK providers now use One Touch Switch: you contact only the new provider and they handle the rest, including cancelling the old service. Households on Universal Credit, Pension Credit and some other benefits can get social tariffs from around £12.50 a month, worth roughly £200 a year.
