Home energy efficiencies: Desirable but too costly?


To accompany our home energy calculator, we asked the British homeowner which energy efficiencies they'd like to make, and what's stopping them from doing so.

50% said making energy efficiencies was "Too expensive", while 20% "Don't believe they'll see a return on investment".

We also asked respondents which efficiencies they would make in their home if there were no financial, legislative or circumstantial constraints, giving us the following top three:
1. Triple Glazing (46%)
2. Solar panels (43%)
3. Floor insulation (26%)


Judging from our energy efficiency calculator, homeowners fears of costly efficiences that don't provide value could be well-founded: making the three most desirable efficiencies in the home has an upfront cost of £10,465, which means it would take 40 years to get a return on the investment. Still, energy efficiencies can be made in the home without a big upfront cost. You could get a great rate on a loan by using our loans comparison tool. Elsewhere, here are five ways every homeowner can start to save money through a more energy efficient home:

  • Change your energy supplier. You could save in excess of £400 a year by comparing gas and electric energy prices and making a switch.
  • Don't leave appliances on standby. By switching off at the plug instead of leaving an applicance on standby, you could save around £30 a year.
  • Turn down your thermostat. Cut 10% from your heating bill by lowering the temperature of your thermostat by one degree - it could deliver a saving of £80 a year.
  • Be smarter in the kitchen. If you're making just the one brew, only fill the kettle with the amount you need and save around £6 a year.
  • Get some help. The government has initiatives in place that can help you pay for energy efficiencies in the home.
