UK broadband loyalty penalty costs households up to £108 a year

A new BroadbandSwitch.uk report says UK broadband customers out of contract pay more for the same service, with the gap reaching £108 a year. The study also says hundreds of millions of pounds in social tariff support remains unclaimed, especially among households least likely to switch.

Why it matters: - Millions of UK households are paying more for broadband even when they receive the same service as next-door neighbours. - The report says the biggest drivers of overpaying are being out of contract and not knowing about cheaper social tariffs. - The findings matter most for low-income households, older customers and people on older, slower lines.

What happened: - BroadbandSwitch.uk published its report, The Loyalty Penalty, on July 22, 2026. - The study pulls together data from Ofcom, Citizens Advice, INCA, Point Topic, and audited results from BT and Virgin Media O2. - It finds that out-of-contract customers pay £7 a month more for standalone broadband, £8 more for broadband and landline bundles, and £9 more for bundles that include TV. - That gap adds up to as much as £108 a year. - At the end of June 2025, 28% of UK broadband customers were out of contract for at least one service in their bundle. - Ofcom says most, but not all, of those customers could save by switching or re-contracting.

The details: - The price gap is not uniform across products. - On broadband and landline bundles, the monthly penalty ranges from £4.17 on a standard package to £7.94 on an ultrafast package. - That works out to roughly £50, £82 and £95 a year depending on tier. - In the year to July 2025, average standalone broadband prices fell 6% in real terms across five speed tiers. - The slowest sub-30 Mbit/s packages were the exception, rising 17% in real terms and 22% in cash terms. - Those older copper-line packages are held disproportionately by older households. - Broadband social tariffs typically cost £12.50 to £20 a month and are available to households on Universal Credit, Pension Credit and other qualifying benefits. - A qualifying household can save around £200 a year by moving to a social tariff. - In June 2025, 532,000 households were on a social tariff, equal to 8.6% of the roughly 6.2 million eligible households. - Ofcom found that 70% of eligible households did not know the tariffs existed. - Citizens Advice estimated that £824 million in social tariff support goes unclaimed each year. - Dr Alex J. Martin-Smith said the social tariff section was included to help households most affected by the penalty. - Just 19% of over-64s switched a communications service last year, compared with 29% of people aged 25 to 44. - By social grade, 21% of DE households switched compared with 27% of AB households. - Low-income households already pay a poverty premium averaging £217 a year across essential markets.

Between the lines: - The report suggests the loyalty penalty is real, but it is also shrinking. - The out-of-contract share has fallen from 40% in 2019 to 28%. - Switching has risen from 14% to 18%. - BT's consumer broadband average revenue fell 1% to £41.80, showing price pressure at major providers. - Challenger fibre networks are winning customers fastest after leaning on price certainty. - Those networks added around 850,000 customers in 2025, while Openreach lost about 860,000 lines. - Since Jan. 17, 2025, Ofcom has banned inflation-linked mid-contract price rises in new contracts. - Any increase must now be set out in pounds and pence before a customer signs. - April 2026 was the last round of the old inflation-linked increases for legacy contracts. - Martin-Smith called the loyalty penalty a consumer harm that charges people for doing nothing wrong.

What's next: - The report urges households to check when their contract ends, because providers must tell customers that date. - It says households receiving Universal Credit or Pension Credit should check social tariffs first. - It also says customers on old, slow packages should compare deals at their address, because full fibre reached 82% of UK homes by January 2026 and often costs the same or less for much faster speeds. - The report is No. 28 from BroadbandSwitch.uk, runs 27 pages, cites 35 named primary sources, and grades each figure by how strongly it is evidenced. - BroadbandSwitch.uk says the report is free to read with no signup, and no provider saw it before publication.

The bottom line: - UK broadband customers can still pay more simply by staying put, but the gap is narrowing as switching rises, contract rules tighten and social tariffs remain underused.
