How to reduce your energy bill in the UK

Energy bills are one of the largest fixed costs for most UK households. While some factors are outside your control — like the energy price cap — there are meaningful actions you can take to reduce consumption and make sure you are on the right tariff.

Check you are on the best tariff

If you are on your supplier's standard variable tariff, you may be paying more than necessary. Use a comparison site to check whether switching tariff or supplier would save you money. The energy market has stabilised compared to 2022-2023, and deals are available again. Check Ofgem's guidance on what the price cap means for your tariff.

Reduce heating costs

• Turn your thermostat down by 1°C — research suggests this can reduce heating bills by around 10%
• Heat only the rooms you use, where possible
• Check your boiler is serviced and running efficiently
• Bleed radiators if some are cold at the top — trapped air reduces efficiency
• Use a timer so heating is only on when needed
• Check if your property qualifies for a Government boiler or insulation grant (GOV.UK has current schemes)

Reduce electricity costs

• Switch to LED bulbs if you have not already — they use significantly less electricity
• Turn appliances off standby — standby costs UK households meaningful amounts each year
• Use your washing machine at 30°C or 40°C rather than 60°C for most loads
• Only run dishwashers and washing machines with full loads
• Check if your tariff offers cheaper off-peak rates (Economy 7) and shift usage accordingly

Check for support you may be entitled to

The Warm Home Discount scheme, Cold Weather Payments and Winter Fuel Payment are available to qualifying households. GOV.UK lists current eligibility criteria. Energy suppliers are also required to offer Priority Services Register to vulnerable customers — contact your supplier to ask about this.
