If you want the same supplier for gas and electricity, then getting a dual-fuel deal will nearly always be cheaper. 

But if you don't mind having separate suppliers, then our research found that going for the cheapest electricity supplier and the cheapest gas supplier would save you even more money.

2. Turn down your thermostat: save £90

Reducing room temperatures by just 1ºC can cut heating bills by up to £85-£90 a year in a typical home, according to the Energy Saving Trust. So put on a jumper rather than turn up the heating.

Already turned down your thermostat? Save even more by turning down the radiators in rarely used or empty rooms and by programming your heating to turn off when you're not there. For more advice, see our top five tips to effectively using your home heating controls.

You might also find a smart thermostat, which lets you operate your heating remotely via the internet, could help you save money. We've tried out smart thermostats - including Nest, Hive and Honeywell Evohome. To find out more, go to .

3. Replace light bulbs: save £70

Energy-saving light bulbs can help you cut your energy bills easily. If you replace 10 light bulbs in your house with energy-saving ones, you could save about £70 a year.

Remember, energy-saving light bulbs do last longer than traditional ones - most CFLs claim lifetimes upwards of 6,000 hours, and LEDs around 25,000 hours, whereas traditional light bulbs last around 1,000 hours.

Replacing just one 60W incandescent with an LED bulb can save almost £7.50 per year. And with Best Buy bulbs from around £5, they can pay for themselves within 12 months. To find out more, see our light bulb reviews.

Already use energy-saving bulbs? Remember to switch off lights when not in use, and use the best bulb for the size of room or the job it will do.

4. Cut draughts: save £50

Stopping heat from escaping through unwanted gaps could help you save up to £50 a year. Take a look at the following areas:

  • Windows Use draught-proofing strips around the frame, Brush strips work better for sash windows.
  • Doors Use draught-proofing strips for gaps around the edges, and brush or hinged-flap draught excluders on the bottom of doors.
  • Chimney and fireplace If you don't use your fireplace, use an inflatable pillow to block the chimney, or fit a cap over the chimney pot
  • Floorboards and skirting Floorboards need to move, so use a flexible silicone-based filler to fill the gaps
  • Loft hatchesYou can prevent hot air escaping by using draught-proofing strips.

Already repaired large draughty areas? Consider smaller holes that let in air, such as keyholes and letterboxes.

5. Choose energy-efficient appliances: save up to £247

If you're replacing an appliance, you can cut your electricity bills by choosing the most energy-efficient model. For example, running costs for washing machines vary between £11 and £50 per year. 

In all our lab tests we reveal the annual running costs for each large appliance, from TVs to fridges. Just check out our energy running cost calculators page for links to tools which tell you how much appliances cost to run, and which ones will be the cheapest.

Choosing the most energy-efficient models can result in annual savings of around £39 for a washing machine, £100 for a tumble dryer and £62 for a fridge-freezer. And our research shows swapping all your kitchen appliances for energy-saving ones could save up to £247 a year.

6. Get a new boiler: save up to £340 a year

Replacing an old G-rated gas boiler which has no controls with a new condensing model, including a programmer, could trim up to £340 a year from the gas bill of a typical home.

But a new boiler is expensive, costing around £2,500 when you include installation. So if saving money is your priority, it’s probably not worth replacing your boiler until it’s beyond economic repair. 

For detailed information on the savings you could make by replacing different types of boilers, read our guide to .

Already replaced your boiler? Make sure you're using it efficiently. Ensure radiators are working properly, and use the boiler programmer so the heating only comes on when you need it.   

Loft insulation

7. Home insulation: save up to £300

Insulating both your loft and cavity walls can save you up to £300, and there are currently a number of free insulation deals to help you pay for it.

Laying loft insulation to a thickness of 270mm in a typical non-insulated three-bedroom semi could trim £140 a year from energy bills, as less heat will be lost through the roof. 

Insulating cavity walls can save around £160 a year. Solid-wall insulation, although more expensive to fit, could save you £260 in the same type of house.

Monitors cost from around £25, but some gas and electricity suppliers give them away free. Read our energy monitor reviews to choose the best energy monitor for you.
