Top 10 energy saving tips

Follow our energy saving tips for quick and easy ways to save energy, lower your bills and improve your carbon footprint. 

We’ve ordered these tips so those with the biggest impact on your bills are first. But if you follow all 10, you could save on your energy bills up to:

  • £351 a year in Great Britain (GB)
  • £416 a year in Northern Ireland (NI)

01

Draught-proof your windows and doors

Unless your home is a new build, you’ll lose some heat through draughts: 

  • around doors and windows 
  • through gaps around the floor 
  • through the chimney 

Getting professional draught-proofing for your windows and doors can save you around £85 in GB and £95 in NI. Professional draught-proofing can cost around £250, but DIY draught proofing can be much cheaper. 

02

Avoid the tumble dryer

Avoid using a tumble dryer for your clothes. Line drying your clothes in warmer weather, or on racks inside the house, can save you £50 a year in GB and £60 in NI. 

03

Spend less time in the shower

Keeping your shower time to just four minutes could save you £45 a year in GB and £65 in NI on your energy bills. If you need some help sticking to that time, we have a list of four-minute shower songs on our water saving tips blog

04

Switch appliances off standby

You can save around £45 a year in GB and £55 in NI just by remembering to turn your appliances off standby mode. 

You can turn almost all electrical appliances off at the plug without upsetting their programming. You can also buy standby savers, which let you turn all your appliances off standby in one go to save electricity. 

Check the instructions for any appliances you aren’t sure about. You may need to leave some satellite and digital TV recorders plugged in so they can track any programmes you want to record. Also remember that some appliances, like fridges and freezers, need to be on all the time. 

Find out which appliances use the most electricity in your home. 

05

Top up your hot water cylinder insulation

If you have a loose 25mm jacket, why not top it up with a British Standard Jacket (80mm thick)? Doing this will help you save £40 a year in GB and £45 in NI. 

Insulating your water tank, pipes and radiators is a quick and easy way to save money on your energy bills. 

06

Don’t overfill your kettle, and fit a tap aerator

Kettles are one of the most used appliances in the kitchen, especially during big TV and sports events. But many people often boil the kettle with more water than they need. 

Avoid overfilling the kettle and you can save yourself £10 a year in GB and £12 in NI on your electricity bill. 

You should also think about fitting an aerator onto your kitchen tap. An aerator is a small gadget with tiny holes that attaches to the spout of your tap. This reduces the amount of water coming out without affecting how it washes or rinses. It’s relatively cheap, easy to install and could save you £20 a year in GB and £20 in NI. 

07

Use fewer, colder washes for your laundry

Save £27 a year in GB and £30 in NI on your electricity bill by making small changes in how you use your washing machine: 

  • Wash your clothes on a 30°C cycle instead of higher temperatures. 
  • Reduce your washing machine use by one run per week for a year. 
08

Fill your dishwasher

Only run your dishwasher when it’s full so you don’t have to run it as often. Reducing your dishwasher use by one run per week for a year could save you £11 a year in GB and £15 in NI. 

09

Swap your bath for a shower

Swapping one bath a week to a four-minute shower could save you £10 a year in GB and £10 in NI.

Find out how saving water at home can help your energy bills and the environment. 

10

Turn off your lights

Turn your lights off when you’re not using them or when you leave a room. This saves you around £8 a year in GB and £9 in NI on your energy bills. 

Also, replacing all the lights in your home with LED bulbs could help you save even more
