Energy Efficiency

Cutting down for lower carbon emissions

You can do so much more for the environment from the comfort of your home besides signing up to our green tariff.

Here’s some of the quick changes you can make to help you budget, save energy and reduce bills. Try them them – you’ll see the difference.

Top Tips:

  • Fancy a cuppa? Only boil as much water as you need.
  • Cover pots and pans when cooking – they’ll boil faster!
  • Defrost your freezer regularly.
  • If you only have a small meal to heat up, using a microwave rather than an oven could save you time and energy.
  • Wash your clothes at 30 degrees – it can be just as effective.
  • Only run your washing machine and / or dishwasher with full loads.
  • Minimise tumble-drying – hang clothes up outdoors or use a clotheshorse indoors where possible.
  • Turning your central heating down by 1 degree could cut your heating bills by up to as much as 10%.
  • Turn your immersion heater down by 1 degree – you’ll save energy and you won’t notice the difference.
  • Use energy-efficient light bulbs.
  • Go paperless for your bills, including with ClickEnergy.


If your home isn’t insulated, you could be losing up to 26% of your heat through the roof and 33% through the walls.

  • Cavity wall insulation could save you up to £115* off your heating bill each year.
  • Use draught excluders.
  • Install double-glazing windows to keep the heat in – and close your curtains at night.

Heating and Hot Water

  • Have your boiler serviced regularly. If the boiler’s old, it’s probably inefficient – so think about replacing it.
  • Make sure your boiler has an insulating jacket.
  • Feeling a bit chilly? Put on a jumper or curl up under a blanket and you’ll be less tempted to turn up the heat.

Washing machines, tumble driers and dishwashers

  • Wash your clothes at 30% - most powders work well at lower temperatures.
  • Consider replacing your old dishwasher with a new Energy Saving Recommended model.
  • Wait until you have a full load for your dishwasher or washing machine, and use the economy cycle if possible.

Smaller appliances – from kettles to radios

  • Don’t leave appliances on standby – turn them off at the wall.
  • Buying a new appliance? Look for the Energy Efficiency Recommended logo.

Lighting – from bulbs to bedside lamps

In most houses lighting takes up roughly 20% of the electricity bill.

  • Fit energy-saving bulbs. They use up to 80% less electricity than standard ones and last around 10 times longer.
  • If you’re leaving a room, remember to turn off the light. It will save energy and money.

Fridges and freezers

  • Keeping the fridge full means that it doesn’t have to work as hard as there’s less empty space to keep cool.
  • Buying a new fridge-freezer? Look for the Energy Saving Recommended stamp.
