Saving Energy With Food and Drink

5. Your fridge doesn’t need to be any colder than 4° C, turn it down if it’s colder than this.

6. Check the energy rating on all appliances you purchase, you want A-rated products only.

7. Halogen ovens use around 70% less electricity than standard ovens. Think about this next time you purchase one.

8. Cook in batches. If you already use a slow-cooker, cook enough for another meal and freeze it (which also fills the void in the freezer).

9. Only buy the size fridge freezer you need. Cooling air, costs money.

10. After your dishwasher finishes the wash cycle, let the contents air dry rather than using the drying cycle.

11. Ovens use lots of energy, stop opening that door!

12. Like heated plates? Use them as a lid for pans for 30 seconds each rather than using a microwave.

13. But if you prefer to microwave, wipe them over with water first, as the heat will distribute evenly.

14. Your freezer can be set at 18° C, turn it down if it’s set below this (some will be set at up to 21° C

15. If you have a dodgy fridge door, or a deteriorating seal, use a fridge door latch to stop cold air being released.

16. Don’t overfill a kettle. Only boil the amount of water that’s needed. Up to £7 per year in savings.

17. Fill up your kettle directly after use. This will help warm up the water ready for your next cuppa’

18. Invest in a slow cooker. They use 3x less electricity than a normal oven.

Read more from Miss Thrifty.

19. Clean the coils on the back of your fridge/freezer. This will help to improve efficiency.

20. Keep heat in when cooking. Use lids on all pots and pans.

21. Reduce the need to defrost in the microwave where possible. Remove items from the freezer prior to cooking.

22. Use a chest freezer over a fridge/freezer where possible, they are more energy efficient.

23. Defrost your freezer. Keeping ice cold is a waste of money!

Read more from First Utility.

24. Limit use of an extractor fan and open windows instead (in summer months).

25. Don’t use the oven for re-heating, use the microwave. The oven uses a tonne of energy!

26. Clean filters on dishwashers, washing machines and dishwashers to improve efficiency.

27. Use the right size pan, for the right size hob. Reduce heat loss.

Read more from Nourished Kitchen.

28. Switch off the hob a few minutes before food is finished cooking. It will continue to cook.

40. Build a solar WIFI booster for your garden. OK. Maybe not as big as this one.


41. Glossy paints will reflect light much better, meaning you won’t have to have high wattage bulbs.

42. Convert your exercise bike into a generator. You do exercise, right?

Saving Energy Outdoors

43. Junk-mail wedged open your letterbox and left your house cold? Use a post-box instead.

44. Solar outdoor lighting can be used for places like pergolas and BBQ seating areas. You don’t need to rely on mains electricity.

63. Save up to £145 per year by insulating your loft

Read more from Love Energy Savings.

64. Board out your loft. Not only will this further insulate the area, but it will stop loft insulation being compressed (which reduces efficiency).

65. Use rugs on tiled or hard-floor areas. This will naturally make your house feel warmer, removing the need to increase the heat.

66. Don’t just insulate the loft, make sure the loft hatch is insulated too using insulation strips

67. Get Government funded cavity wall insulation.

Read more from Gov.UK.

68. Check your loft insulation hasn’t degraded over time. Top up if necessary. This could save you £25 per year.

Saving Energy Via Central Heating Systems

69. A kinetic fan will help circulate heat around a room, making it feel warmer.

70. Save up to £350 by having your boiler replaced.

71. Install an outdoor sensor and reduce gas usage by 2%.

72. New radiators can improve efficiency by up to 50%.

73. Using TRVs on radiators will allow you to control heat and reduce wastage.

74. Central heating pumps usually have 3 settings. Turning this down (where possible) will reduce electricity consumption.

75. Products such as Radflek will reflect the heat from radiators back into the room (rather than the wall).

76. Install thermostats in a central location. If it’s installed by a door or window, cold drafts will trick it into thinking the room is colder than it is (and cost you more in gas).

77. Turn down the room thermostat by just a few degrees to save energy (and approximately £45/year per 1 degree reduction).

78. Leave room between radiators and furniture, so the heat can circulate around the room.

79. Get curtains turned up so they fit easily behind radiators, rather than in front of them. This will help heat circulate around the room.

80. Using a dual flush system can reduce water wastage by 50%.

81. Tap aerators will mix water with air. Flow rate is reduced but it will seem like pressure isn’t.

82. A smart thermostat allows you to set a max setting from your phone. No amount of finger turning can get it above this setting.

83. A boiler losing pressure is under unnecessary strain. Get it fixed as soon as possible.

84. Get a radiator booster. This absorbs heat from behind radiators and fans it around the room.

85. Get an automatic bleed valve for radiators. Keeping radiators bled is essential to their efficiency.

86. Use a central place to charge devices. Approximately 8% of household energy, is doing nothing. Flick the switch when you’re done.

87. Set heating to come on before you get home (and the temperature rise slowly) rather than putting it on full blast (the later uses more energy).

88. Use a water efficient shower and save up to £50 per year on gas.

Read from the Energy Saving Trust.

89. Fit an efficient shower head and save £40 per year.

From Water Wise.

90. Reduce the pressure setting on your shower.

    That is ONE. BIG. LIST! Never came across such an exhaustive list of tips before. We follow most of them with the most recent addition being the smart meter by Ohm Assistant (https://ohmassistant.com/). This is built with machine learning so no sensors in individual appliances and therefore non-bulky and easy to set up. By this, we’re able to monitor the power consumption of our devices on our smartphones.
