Energy bills are one of the biggest household costs in the UK. Even with the energy price cap, the average household pays over £1,700 per year on gas and electricity. The good news is that there are dozens of practical ways to reduce that figure — some free, some requiring a small investment that pays for itself quickly.
Switch to a Better Tariff
Heating: The Biggest Cost
- •Turn the thermostat down 1°C: This alone can save £80-£100 per year. Most people can't feel a 1-degree difference.
- •Use a timer: Don't heat an empty house. Set your heating to come on 30 minutes before you wake up and switch off when you leave.
- •Heat the room, not the house: Close doors to rooms you're not using. Use a portable electric heater for one room if it's cheaper than heating the whole house.
- •Bleed your radiators: Trapped air makes radiators less efficient. Bleed them at the start of winter. It takes 5 minutes with a radiator key.
- •Use thermostatic radiator valves (TRVs): Set different temperatures for different rooms. Bedrooms don't need to be as warm as the living room.
Insulation and Draught-Proofing
- •Loft insulation: If you have less than 270mm, topping up is cheap (sometimes free through government grants) and saves £150-£250 per year.
- •Cavity wall insulation: Saves £100-£300 per year. Check if your home is eligible through the Energy Company Obligation (ECO) scheme.
- •Draught-proofing: Seal gaps around windows, doors, letterboxes, and keyholes. A £20 draught-proofing kit can save £30-£50 per year.
- •Curtains and blinds: Thick curtains across windows and external doors reduce heat loss significantly. Close them at dusk.
- •Hot water tank jacket: If you have an uninsulated hot water cylinder, a £15 jacket saves about £35 per year.
Electricity Quick Wins
- •LED bulbs: Replace any remaining halogen or incandescent bulbs. LEDs use 80% less energy and last years longer.
- •Turn things off at the plug: Standby mode on TVs, consoles, and chargers wastes £50-£80 per year across a typical household.
- •Wash at 30°C: Modern detergents work perfectly at 30°C. Heating water is the expensive part of a washing cycle.
- •Air dry clothes: Tumble dryers are one of the most energy-hungry appliances. Use a drying rack or outdoor line when possible.
- •Use the microwave: Microwaves use far less energy than ovens for reheating and small meals. Air fryers are also more efficient than conventional ovens.
Government Help and Grants
- •Winter Fuel Payment: £200-£300 for households with someone over State Pension age.
- •Warm Home Discount: £150 off your electricity bill if you're on certain benefits or low income.
- •ECO4 scheme: Free insulation and heating improvements for eligible households. Check with your energy supplier.
- •Boiler Upgrade Scheme: Grants of £5,000-£7,500 towards heat pumps. Worth considering if your boiler needs replacing.
FAQ
Should I get a smart meter?+
Yes. Smart meters are free and show you exactly what you're spending in real time. Studies show people with smart meters reduce their energy use by 3-5% just from the awareness. You also get accurate bills instead of estimates.
Is it cheaper to leave the heating on low all day?+
No. This is a persistent myth. The Energy Saving Trust confirms it's cheaper to heat your home only when you need it, using a timer. Leaving it on low all day loses heat continuously through walls and windows.
Are solar panels worth it in the UK?+
Increasingly yes, even in cloudy Britain. A typical 4kW system costs £5,000-£7,000 and saves £500-£800 per year. With the Smart Export Guarantee paying for excess electricity, payback is typically 8-12 years. After that, it's free electricity.
