UK Households Spend £6,157 a Year on Bills — What Cashback on That Is Actually Worth

The average UK household spends £118.40 a week — £6,156.80 a year — on housing (net), fuel and power, according to the Office for National Statistics. That's exactly the kind of recurring direct debit spending — energy, water, council tax, broadband — that cashback current accounts are built to reward. Applying real, clearly-labelled cashback rates to that figure shows what it's actually worth, and what it isn't.

The source figure

ONS Family Spending in the UK, financial year ending March 2025, published 11 June 2026, puts average weekly UK household expenditure on housing (net), fuel and power at £118.40 — the single largest category of household spend, at 18% of the £676.60 weekly total. Annualised: £6,156.80.

This category is a reasonable proxy for "bills you'd pay by direct debit regardless" — it's not spending you'd do to chase a reward, which is the only kind of spending worth running through a cashback calculation. It excludes groceries, fuel at the pump and discretionary card spending, which some cashback products also reward — so the figures below are a floor, not a ceiling.

What a range of real cashback rates is worth on that

These are illustrative rates in the range UK cashback current accounts and bill-cashback schemes have advertised — not a live offer from any named provider. Net of a typical £2–£3 monthly account fee, and before any cap:

Cashback rate	Gross annual reward on £6,156.80	Less a £3/month fee	Net annual value
0.5%	£30.78	−£36	−£5.22 (fee exceeds reward)
1%	£61.57	−£36	£25.57
2%	£123.14	−£36	£87.14
3%	£184.70	−£36	£148.70

The table makes the actual decision visible: at 0.5%, a £3 monthly fee wipes out the reward entirely — the account would need to be fee-free, or the rate higher, to be worth holding for bills alone. Most of the real value in bill-cashback accounts sits at 1%+ once a fee applies, and many real products also apply a monthly cap well below the uncapped figures shown here — check the cap first, because it usually binds before the rate does. Run your own bills through the net cashback calculator with a specific account's actual rate, cap and fee.

Why this is a floor, not an average person's total

Two things this figure deliberately doesn't do:

• It's not "the average household's cashback." No public data tracks actual UK cashback uptake or redemption, so this isn't an estimate of what households currently earn — it's what the spending they already have would return under stated rates, which is a fair test of whether a specific account is worth opening.
• It only covers one ONS category. Households also spend on food, transport fuel and communications — some of which qualifies for cashback on other products (supermarket cashback cards, fuel cards). Adding those would raise the eligible base above £6,156.80, not lower it.

The comparison that actually matters

The number that matters for any individual household isn't the ONS average — it's your own recurring direct debits against the specific account's fee, cap and rate.
