The cost to do so? Nothing.
LED light bulb replacements
Replacing the bulbs in your house with LEDs can cost around £280. In a year, it could save you around £139.
Switch off electrical appliances
Getting into the habit of switching off electrical appliances, such as your TV and laptop, rather than leaving them on standby costs absolutely. However, it can save you around £48 a year.
On the topic of electrical appliances, if you're looking to upgrade, make sure you keep an eye out for energy-efficient appliances.

Turn off the lights
Did you even grow up in the UK if your parents didn't say the house was like the Blackpool illuminations if you left a single light on?
They may have been slightly exaggerating, but they are right. Switching off the lights when you're not in the room could save you £17 a year (and doesn't cost you anything to do!).
Avoid the tumble dryer
Tumble dryers use a lot of energy to dry your clothes. You can save money by hanging your washing on the line in warmer weather or by using an indoor drying rack in cooler months.
Making this change costs £0, but can save you £52 a year.
Don't overfill the kettle
By simply filling up the kettle with only the water you need, you can save yourself £10 a year.
Increase the jacket thickness on your hot water cylinder
When you wear more layers, you feel warmer, and the same goes for your hot water cylinder.
Increasing the jacket thickness on your hot water cylinder to 80mm can cost £50, and save you around £34 a year. Not a bad little saving each year for what is essentially a coat!
Wash clothes at a lower temperature
Do you really need to wash all of your clothes on the hottest wash possible?
Simply turning the temperature down on your washing machine from 50 degrees C to 30 degrees C can save you around £25 a year.
Better still, it costs you absolutely nothing to do, and your clothes will still be clean.
Defrost your freezer
The frostier your freezer, the harder it's got to work to keep your food frozen. The best way to get it running at its optimum is to defrost it. This costs you nothing but can save you £44 a year.
