Household bills — energy, broadband, insurance, subscriptions, council tax — are often the fastest route to meaningful savings because many people are paying significantly more than they need to. A systematic review of each bill, done once a year, can save hundreds of pounds annually with minimal effort.
Energy bills
Energy is typically the largest household bill outside of rent or mortgage. Key actions:
- Check the Ofgem price cap — the cap sets a maximum unit rate, but some tariffs from smaller suppliers or fixed deals may be cheaper
- Submit regular meter readings — estimated bills can lead to overpaying and then scrambling to catch up
- Reduce usage — turning the thermostat down by 1°C saves around 10% on heating bills. Switching to LED bulbs, reducing standby usage, and washing at 30°C all add up
- Apply for available grants — the Warm Home Discount, Cold Weather Payments, and local authority energy efficiency grants are available to eligible households
Broadband and phone
Loyalty rarely pays in telecoms — providers routinely charge existing customers more than new ones. Check your contract end date and compare deals on comparison sites (MoneySuperMarket, uSwitch, Broadband Genie) when your contract expires. Switching can save £100–£200 per year on broadband alone. Many providers also offer significant discounts if you bundle broadband and mobile.
Insurance
Auto-renewing insurance policies almost always result in paying more than necessary. Compare home, car, and life insurance on comparison sites annually — the savings for new customers versus renewal prices are often substantial. Use two or three comparison sites as they don’t all cover the same providers.
Subscriptions
Most households are paying for subscriptions they rarely use. Audit yours — streaming services, gym memberships, delivery passes, software, magazines, apps — and cancel anything you haven’t actively used in the past month. Subscription creep is one of the most common hidden sources of wasted money.
Council tax
Check you’re in the right council tax band — a significant number of UK properties are incorrectly banded, often too high. You can check your band and challenge it via the Valuation Office Agency (England and Wales) or the Scottish Assessors Association (Scotland). Also check eligibility for council tax discounts — a 25% single person discount applies if you live alone, and various other discounts and exemptions exist.
Water bills
If you live alone or in a small household, switching to a water meter can significantly reduce your water bill. Contact your water provider to request a meter — you can usually revert to a rateable value charge within a trial period if it turns out to be more expensive.
Frequently asked questions
How much can I save by switching energy suppliers?
This depends on current market conditions and the Ofgem price cap. When fixed deals are cheaper than the variable cap, switching can save hundreds per year. Always compare on uSwitch or MoneySuperMarket before switching.
What bills can I negotiate?
Broadband, mobile, and TV packages are the most commonly negotiable. Call your provider when your contract is ending, have a competitor quote ready, and ask for a better deal — retention teams often have access to offers not advertised publicly.
How do I check if I’m in the wrong council tax band?
Check the Valuation Office Agency website (voa.gov.uk) to see your property’s band and compare it to similar neighbouring properties. If yours appears higher, you can submit a challenge — if successful, you’ll receive a refund backdated to when you moved in.
