UK broadband study finds households overpaying by hundreds

A hand-checked study of 377 broadband deals across 33 UK providers says many households are paying loyalty penalties after contracts end, while cheap social tariffs starting at £12.50 a month remain widely unclaimed. The findings matter because they point to hundreds of pounds in avoidable annual costs for out-of-contract customers and eligible low-income households.

Why it matters: - Out-of-contract broadband customers are paying a loyalty penalty that can add up to hundreds of pounds over a typical contract. - Social tariffs can cut broadband bills sharply for households on qualifying benefits, but most eligible households are not using them. - The gap hits both higher-income households that drift off contract and lower-income households that qualify for cheaper support but do not know it exists.

What happened: - BroadbandSwitch.uk hand-checked 377 broadband deals from 33 UK providers and compared each price with the provider's own listing. - The study found that households staying with the same provider after contract expiry are often paying more than they need to. - The study also found that social tariffs, the lower-cost broadband packages for people receiving qualifying benefits, are going unclaimed by many eligible households. - The evidence pack for the study is published on the BroadbandSwitch.uk website, where households can also compare deals and check social tariff eligibility. - Media enquiries can be submitted at the company's media page.

The details: - Ofcom reports that 28% of UK broadband customers are out of contract. - Ofcom also reports that those out-of-contract customers pay between £7 and £9 more a month than people on current deals. - That gap equals £84 to £108 a year, or £168 to £216 over two years, before any mid-contract price rise. - The cheapest verified deal in the study was £14 a month for full fibre from Community Fibre in London. - The average cheapest deal across all 33 providers was £22.55 a month. - Gigabit full fibre now starts at £20 a month. - Social tariff prices verified in the study start at £12.50 a month. - Ofcom reports that around 70% of eligible households do not know social tariffs exist, which helps explain the low take-up. - For a family on a lower income, the difference between a standard deal and a social tariff can exceed £150 a year. - Since 17 January 2025, providers have had to state any mid-contract price rise in pounds and pence rather than as a percentage. - Several large providers, including BT, EE, Plusnet, TalkTalk and Virgin Media, add a fixed £4 a month increase each year on the deals checked. - That fixed rise totals £96 over a two-year contract. - Smaller networks including YouFibre, Zen, Fibrus and Truespeed hold their price for the full contract. - The study was sorted by what a household pays across the first year. - Prices depend on postcode.

Between the lines: - The biggest savings are not always on the best-known brands. - Newer networks can undercut legacy providers, but availability varies street by street. - The market appears to reward inertia, especially when customers do not check whether they have fallen out of contract. - Awareness is a major barrier for social tariffs, so the cheapest option may also be the hardest to find.

What's next: - BroadbandSwitch.uk says households should check whether anyone in the home receives a qualifying benefit, since a social tariff may be the cheapest route. - The study advises households to check their postcode because the lowest prices come from newer networks that do not reach every area. - The study also urges customers to avoid drifting out of contract, where the loyalty penalty applies. - Dr Alex J. Martin-Smith said the main priority is raising awareness so eligible households do not miss cheaper tariffs and customers who forgot to switch can still save money.

The bottom line: - The cheapest broadband deals are available, but many UK households are paying more because they are out of contract or unaware of social tariffs.
