UK broadband loyalty penalty can cost households up to £108 a year

A new BroadbandSwitch.uk report says UK broadband customers out of contract are paying up to £108 more a year for the same service, while £824 million in social tariff support goes unclaimed. The findings highlight how staying put can quietly raise bills, especially for older, slower connections and low-income households.

Why it matters: - Out-of-contract broadband customers are paying more for the same service, turning loyalty into a measurable household cost. - The gap can reach £108 a year, which adds pressure on budgets already facing higher prices in essential markets. - The report also points to a large amount of unclaimed social tariff support that could reduce bills for eligible households.

What happened: - BroadbandSwitch.uk published The Loyalty Penalty on July 22, 2026. - The report draws on data from Ofcom, Citizens Advice, INCA, Point Topic and audited results from BT and Virgin Media O2. - It finds that customers out of contract pay £7 a month more for standalone broadband, £8 more for broadband and landline bundles, and £9 more for bundles that include TV. - At the end of June 2025, 28% of UK broadband customers were out of contract for at least one service in their bundle.

The details: - The monthly penalty is not flat across products. - On broadband and landline bundles, the gap ranges from £4.17 a month on a standard package to £7.94 a month on an ultrafast package. - That equals about £50 a year on the low end, £82 a year in the middle and £95 a year at the top of that range. - 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 rose 17% in real terms, or 22% in cash terms. - Those slower packages are tied to older copper lines and are held disproportionately by older households. - Broadband social tariffs are discounted packages, typically priced at £12.50 to £20 a month, for households on Universal Credit, Pension Credit and other qualifying benefits. - Social tariffs can save an eligible household around £200 a year. - In June 2025, 532,000 households were on a social tariff. - That represented 8.6% of the roughly 6.2 million households eligible for the support. - Ofcom found that 70% of eligible households did not know the tariffs existed. - Citizens Advice estimated that £824 million of social tariff support goes unclaimed every year. - BroadbandSwitch.uk founder Dr Alex J. Martin-Smith said the social tariff section was included to help households most affected by the penalty.

Between the lines: - The report suggests the biggest risk is not just higher bills, but inertia. - Ofcom says most out-of-contract customers, though not all, could save by switching or re-contracting. - Just 19% of over-64s switched a communications service last year, compared with 29% of adults age 25 to 44. - Among social grades, 21% of DE households switched versus 27% of AB households. - Low-income households already pay a poverty premium averaging £217 a year across essential markets. - The report says the overall market is improving: the out-of-contract pool fell from 40% in 2019 to 28%, and switching rose from 14% to 18%. - BT's consumer broadband average revenue fell 1% to £41.80. - Challenger fibre 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 new price increase must now be set out in pounds and pence before a customer signs. - The last round of old inflation-linked increases worked through legacy contracts in April 2026.

What's next: - BroadbandSwitch.uk says households should check when their contract ends, since providers are required to tell customers. - Households receiving Universal Credit or Pension Credit should check social tariffs first because they offer the biggest saving in the report. - Customers on old, slow packages should compare deals at their address, especially as full fibre reached 82% of UK homes by January 2026. - The report argues that many full fibre deals cost the same or less while delivering much faster speeds. - The Loyalty Penalty is Report No. 28 from BroadbandSwitch.uk. - The report runs 27 pages, cites 35 named primary sources, grades each figure by evidence strength and is free to read with no signup. - BroadbandSwitch.uk says no provider saw the report before publication.
