Free Boilers

Boilers account for around 55% of what you spend in a year on energy bills, so an efficient boiler makes a big difference.

Replacing an old gas boiler with an A-rated high-efficiency condensing boiler and improving your heating controls will significantly cut your home's carbon dioxide emissions - and could save you as much as £310 a year.

Boilers installed in the UK are required to be condensing boilers. These are far more efficient than traditional boilers as they release gas at just 55 degrees Celsius (rather than 180 degrees), therefore requiring less energy to generate the same amount of heat.

Saving with New A Rated Boiler?

Old Boiler Rating

  • G ( < 70 % )
  • F ( 70–74 % )
  • E ( 74–78 % )
  • D ( 78–82 % )

Annual Saving

  • £ 310
  • £ 205
  • £ 155
  • £ 105

CO2 Reduction / Annam

  • 1,200 kg
  • 810 kg
  • 610 kg
  • 430 kg

These are estimated figures based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached gas heated home with three bedrooms.

The costs for replacing a boiler will vary, but a straightforward gas boiler replacement will typically cost around £2,300.

Saving with New A Rated Boiler?

Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue. A condensing boiler has a bigger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

Sometimes the flue gases get so cool that the water vapour in the gas condenses out (hence the name). When this happens, even more energy is recovered from the condensing vapour, and the efficiency gets higher still.
