Cost of living 2026: what you can claim back

Inflation has cooled, but the cost of living in the UK remains sharply higher than it was four years ago. The schemes below are the ones that move the most money for the most ordinary households this year. The list is in priority order: not by the size of any individual win, but by the realistic combination of how likely you are to qualify and how big the typical payout is.

Cost of living 2026: what you can claim back

The top five for 2026

If you do nothing else this year, do these in this order:

Marriage Allowance, if you are married or civilly partnered with one basic-rate taxpayer and one non-taxpayer. Up to £1,260 for a first-time claim. Full guide →
Council Tax Single Person Discount, if you are the only adult counted in your home. Around £570 a year in England, plus backdating. Full guide →
Lodge a Motor Finance complaint with the lender now if you had a car finance agreement between April 2007 and November 2024. A court suspended part of the FCA scheme on 2 July 2026, so there is no payout date and no letter to wait for. Complaining is free and open until 31 August 2027. The FCA estimate averages about £830 an agreement. Full guide → How to check →
Mastercard Merricks settlement, if you were a UK adult between 1992 and 2008. Around £45 each (estimate) for five minutes of registration when the portal opens. Full guide →
Uniform or Professional Subs tax relief, if you wear a uniform or pay a professional body. £12 to £200+ a year, four years of backdating. Full guide →

Household bills

Three schemes that quietly take money off the running cost of your home:

Water Surface Drainage Rebate if rainwater from your roof goes into a soakaway, watercourse, or private drain rather than the public sewer. £30 to £120 a year, six years of backdating. Full guide →
Broadband and landline auto-compensation if you have had service drop-outs, missed engineer appointments, or a delayed service start. Daily rates set by Ofcom. Full guide →
Smart meter missed appointment: £30 per missed slot. Full guide →

If you are employed

HMRC has a row of small reliefs that compound nicely:

Marriage Allowance if you are married/CP with the right income split.
Uniform tax relief if you wear work clothing you launder yourself.
Professional Subscriptions if you pay an annual fee to a body on HMRC List 3.
Working From Home if your employer requires you to work at home (post-2022 rules tightened).
Overpaid PAYE / P800: log into your Personal Tax Account and check for any reconciliation due. Median refund ~£200.

If you use transport regularly

The four pipelines we automate, and the realistic numbers for each:

Train Delay Repay: ~£60 to £200 a year for a regular commuter. Full guide →
UK261 flight compensation: typically £220 per long delay; many people have one or two qualifying journeys a year. Full guide →
TfL refunds: ~£100 to £400 a year for a regular commuter, often hidden in incomplete journeys you did not notice. Full guide →
UK parking fines: appeals are free; 33% of challenged council PCNs are overturned. Worth doing if a fine looks unjust. Full guide →

Longer-term wins

Council Tax Wrong Band Challenge, with the full risk warnings. Big upside, real downside, careful process. Full guide →
Tenancy Deposit Protection penalty if your landlord did not protect the deposit on time. Full guide →
Pension pot tracing via the free Pension Tracing Service if you have changed jobs more than two or three times in your career. Average lost pot is around £9,500.
Pension Credit if you or a parent is over State Pension age and on a low income. Average award around £3,900 a year and unlocks several other discounts.

Questions readers ask

Why is Marriage Allowance number one?

Because it is high-probability for a large pool (around two million eligible UK couples), the payout is meaningful (£252 a year plus four years of backdating), the form is genuinely free, and the result feels concrete. Few interventions hit that combination.

I am on benefits. Are there things specific to me?

Yes. Pension Credit if you are over State Pension age (worth around £3,900 a year on average and unlocks Warm Home Discount and free TV licence over 75). Council Tax Reduction. The Household Support Fund through your local council. We have not built deep guides for these yet because the rules vary by council, but the gov.uk pages and Citizens Advice cover them well.

I rent. Where should I focus?

Tenancy Deposit Protection if you have any uncertainty about the deposit. Council Tax Single Person Discount if applicable. Water surface drainage if your home is not on a public sewer. The renting category often has the highest individual payouts (deposit penalties can be £3,000+) but lower frequency than the tax-relief items.
