Top five ways to save on your energy bills as the clocks go back

With winter on its way, make key energy savings

Adjusting the temperature on a thermostat

Adjusting your thermostat is one simple way to save on your energy bills

When the clocks go back, it’s time to snuggle to the sofa, pop a blanket over your knees and take our expert advice on how to save money on your energy bills during the winter.

From home insulation to getting the best boiler service, we have tips that could save you hundreds of pounds.

So whether you’re looking at servicing a Best Buy boiler, or getting the best deal from one of the best energy companies, read on.

1. Cut the draughts – save £50 a year

Full draughtproofing could save you up to £50 a year and most methods are simple to do yourself.

For example, a weatherbar to stop cold air coming in under your front door, or a letterbox draught excluder, are both available at many DIY shops.

You’ll need the help of a professional for some jobs and homes, such as older buildings with single glazing.

Visit our full guide to draughtproofing to find out what simple changes you could make, what you’ll need to get a professional in for and what draughtproofing methods you should avoid.

2. Turn down your thermostat – save £85 to £90

Turning down the heating in rooms, even by just 1°C, can save you around £85 a year, according to the Energy Saving Trust.

Set the room thermostat to 18°C and then turn it up by one degree each day until you find a temperature you and your family are comfortable with. 

The temperature shouldn’t drop below 16°C for elderly people and those with mobility problems.

3.  Insulate your home – save £300

Insulating both your loft and cavity walls can save you up to £300: up to £140 a year by insulating your loft and £160 with cavity wall insulation.

Professionally installed loft insulation for a typical three-bedroom, semi-detached house with gas central heating costs around £300. 

It will take around two years to pay for itself through the savings you’ll make on your heating bills, but after that you’ll be saving.

Insulating cavity walls can save around £160 a year, with a payback time of three years.

4. Switch your energy supplier – save £297

If your fixed energy deal is coming to an end soon, don’t wait to switch your energy tariff. 

If you do nothing, you will be transferred onto your supplier’s standard tariff, which could be more expensive.

Our research found that – if you’re on a standard tariff with one of the Big Six energy companies – you could save up to £297 a year by switching to the cheapest deal.

5. Get a boiler service – save your life

Boilers can be very dangerous if they go wrong, so it’s important to get a good boiler service every year. 

But, our recent undercover investigation, which used hidden cameras, revealed a number of boiler servicing engineers breaking the law and making dangerous mistakes.
