On average up to 60% of your energy bill is for energy to heat your home. The easiest way to reduce your energy costs is to make sure you have a modern efficient boiler, however there are many other ways to improve your efficiency and bring down those energy costs. If you would like to know how to save hundreds of pounds a year on your energy bill then keep reading and we will guide you.

The Boiler

The boiler is at the core of your home heating system and you may be eligible for a brand new one completely free! Our government is always trying to meet new energy consumption targets and one of the ways they are trying to achieve this is to give access to free boilers for eligible households.
You may be eligible if your household meets one of the following criteria:
  • The current boiler is over 10 years old
  • The current boiler is inefficient (F or G rated)
  • The current boiler has been condemned
  • The current boiler has parts that are obsolete


If you believe you may be eligible for a free boiler (supply and installation) then simply give us a call and we will take the necessary details for assess your situation for a claim.
Even if you are not eligible for a free boiler it still may be financially beneficial to upgrade your current boiler depending on its performance and fuel type.
The following shows the average fuel costs and efficiency for different boiler types and property types:
Boiler TypeFlatSemi-DetachedDetachedEfficiency
Old Gas Heavy Weight £779 £1,204 £1,705 55%
Old Gas Light Weight £659 £1,019 £1,442 65%
New Non-Condensing £549 £849 £1,202 78%
New Condensing £481 £744 £1,053 89%

(A boiler that is 15 years old or more is classed as 'old' in the above calculations. A lightweight boiler can be attached to a wall; a heavyweight boiler is floor standing.)

Energy Saving Measures



A powerflush will clean out any debris, rust and sludge that has accumulated within your central heating system and restore the full circulation of water, improving the output of your boiler and radiators.



Sludge in your central heating system is a mix of metal oxides, which means it is magnetic. A Magnaclean is a clever invention that uses powerful magnets to filter and catch the metal oxides in your system.



Inhibitor is designed to ensure your central heating system doesn't develop rust and metal oxide waste. All new installations from AA Plumbing will have inhibitor added to the system.


Thermostat / TRV's

Fitting a thermostat can save you £30 a year (based on a 3 bedroom home). TRV's give you even more control and customers have reported savings of 30% or more by targeting the rooms they want to heat.


Insulation Jackets

An insulation jacket will fit around your water tank (if applicable) and can save you £40 a year through reducing up to 75% of the heat escaping through the walls of the water tank.


Radiator Reflector / Fans

Reflectors are fitted behind your radiator and reduce the heat wasted through the external wall. Radfans sit on top of your radiator and blow the warm air directly into the room rather than just up.

Heat Loss Surveys

AA Plumbing undertakes heat loss surveys for a range of domestic customers, development companies and estate agents. One of our surveyors will visit your property to take measurements and make note of the materials used in the construction of your property.
From the information gathered we will calculate the energy requirement for each room.
Our heat loss report will provide you with all the figures used in the calculations and recommend a radiator size for each room.
