UK household bills are one of the biggest drains on take-home pay. Tackling them systematically — rather than one at a time — can save £1,000 to £3,000 or more per year. This checklist covers every major bill category in priority order.
Energy Bills
Energy is often the largest household bill. With the Ofgem price cap governing most standard variable tariffs, comparison and switching opportunities arise each quarter. Always check whether a fixed tariff with a reputable supplier beats the cap.
- Compare fixed vs variable tariff each quarter
- Check for ECO4 eligibility — free insulation could save £300-£500/year
- Warm Home Discount: £150 off electricity for eligible households
- Smart meter: eliminates estimated bills, enables time-of-use tariffs
- Draught-proofing: low-cost DIY saves £30-£80/year
Broadband and Phone
Broadband and phone contracts are often overpaid. The combination of switching and SIM-only mobile can save £400-£600/year.
- Check contract end date — out-of-contract broadband is expensive
- Switch broadband via comparison: typical saving £10-£20/month
- Mobile: switch to SIM-only after handset is paid off
- Social tariffs: broadband from £12/month if on UC or Pension Credit
- Negotiate with current provider before switching — often matches new deals
How long does broadband switching take?
Switching between Openreach-based providers typically takes 7-14 days with no interruption via the One-Touch Switching process. Your new provider manages the whole thing.
Insurance
Never auto-renew any insurance. Car insurance, home insurance, and life insurance should all be shopped annually.
- Car insurance: compare 25 days before renewal for cheapest rates
- Home insurance: switch annually — never auto-renew
- Use comparison sites AND check insurer directly for some
- Stack cashback from TopCashback or Quidco on insurance purchases
- Review whether all add-ons are necessary — accidental damage, legal cover, etc.
Council Tax
Council tax is one of the most underchallenged and underdiscounted bills. Check your band, check for discounts, and apply for reduction if applicable.
- Check your council tax band: 50% of UK homes may be in wrong band
- Appeal band challenge: averages £1,700 saving if successful
- Single person discount: 25% if only adult in property
- Council Tax Reduction: up to 100% off for lowest incomes
- Student exemption: full-time students pay nothing
