How to reduce your energy bills at home

Energy remains one of the largest household costs in the UK. Small behavioural changes and a few simple checks can make a meaningful difference to your bill.

Energy bills have remained elevated for UK households following the price rises of recent years. While you cannot control the unit rate, there are practical steps that can reduce how much energy you use — and the difference they make to an annual bill is often more significant than people expect.

Check you are on the right tariff

With energy prices having moved significantly, it is worth comparing your current deal against available tariffs. Use a comparison site to check whether you would benefit from switching. Even if you are on a fixed tariff, knowing your options helps you make a decision when it ends.

Submit meter readings regularly

If you do not have a smart meter, submitting regular meter readings ensures you are billed for what you actually use rather than estimated amounts. Estimated readings can lead to overpayment that takes months to credit back. Monthly readings take less than a minute.

Check your boiler and heating settings

Heating accounts for the majority of energy use in most UK homes. Lowering your thermostat by one degree can reduce your heating bill by around ten per cent. Checking that your boiler flow temperature is set correctly for your system is worth doing — many combi boilers are set higher than necessary from installation.

Switch devices off standby

Devices left on standby account for a small but measurable portion of electricity use. Smart plugs with timers or power strips with individual switches make it easier to fully cut power to entertainment systems, chargers, and kitchen appliances that do not need to stay on overnight.

Check whether you qualify for energy support schemes

Schemes like the Warm Home Discount, Cold Weather Payments, and Winter Fuel Payment are available to qualifying households. Eligibility depends on your circumstances. The Benefits Checker in Ask Fin can help you identify whether you might be entitled to any of these.
