Gas Boiler Energy Performance
Domestic gas heating boilers in the UK are rated according to energy efficiency.
The organisation which determines a gas central heating boiler’s grading is SEDBUK (Season Efficiency of Domestic Boilers in the UK). SEDBUK. Boiler ratings are determined are determined at the time when the boiler and hot water / heating system is installed, although it is possible to have it assessed at any time by a Domestic Energy Assessor.
Boiler and central heating performance contributes to the overall energy performance of your property and is included in any Energy Performance Certificate or Report Boiler performance is measured as a percentage although the European Grading method (A-G according to energy usage performance) is also often included for consistency.
The energy efficiency of gas boilers (the free boilers available in the UK are gas boilers) is assessed on a variety of factors including –
- Seasonal conditions
- Boiler / heating usage patterns
- Housing occupancy at the time of boiler installation
- Boiler storage conditions
- Boiler Location
- Boiler insulation
Other factors deemed to affect the energy efficiency of boilers such as climate and the age of a boiler are also taken into account when assessing a boiler’s performance. The boiler rating system is designed to be a fair and accurate method of determining boiler efficiency, regardless of manufacturer.
Energy Performance certificates
All boilers installed the UK now must have an energy performance certificate. They also must have a Grade A rating.
If your boiler is not A rated you my be entitled to a free boiler via the boiler grant scheme. In order to qualify for a free boiler your existing boiler must not be a condensing boiler.
If you are unsure about your boiler or its energy rating you can get it surveyed by a Domestic Energy Assessor. The assessor will come to your home and determine the energy-efficiency grade of your boiler and tell you if you qualify for a grant.

Boiler efficiency – energy savings
Government boiler grants have been put in place so that homes can be more energy efficient. All boilers installed in the UK via the Free Boiler Grant Scheme are A-rated Gas Condensing Boilers which use less energy to heat your home and hot water. Condensing Boilers
This means that because less energy is being used there is a reduction in harmful CO2 emissions being released into the environment.
Installing an energy-efficient boiler will also mean savings on your gas /heating bills. An A rated gas boiler will heat your home and hot water for less.
The table below shows how much you can save by installing an A rated gas boiler via the Free Boiler Scheme.
