Do you need Energy Efficiency Advice on buying a new boiler?

The typical home central heating boiler accounts for around 60% of your average spend on household energy bills. A new A rated efficient boiler can make a big difference.

It does not matter if you are having a boiler installed for the first time or if you are having a replacement boiler, or even upgrading you’re old heating system. It does not make any difference if you are a Gas, Oil or LPG energy user as this article will be of interest to all.

On average if you change your old G rated boiler (for example an old gas fired back boiler) with a new high efficiency condensing boiler whilst at the same time improving your overall heating controls, you should significantly reduce your household energy bills – saving as much as £225 a year.

The current lifespan of a new modern A rated high efficiency condensing boiler is around 12 years. Fitting a new boiler and heating controls could save you a quarter of your heating bills.

If your current boiler is 15 years old or more then it is most likely to be a G rated boiler. To replace any old G rated boiler with a new efficient A rated condensing boiler will save you money although if your boiler is younger any savings will be less.

Boiler Types.

There are 2 types of high efficiency condensing boiler; Combination (combi) and System or Open Vented.

Combination or Combi condensing boilers provide all your central heating requirements and the boiler is sized against the number of radiators/ under floor heating and the total heat requirement for the home. Whilst at the same time providing instant hot water without the need for a hot water storage cylinder.

System or Open Vented condensing boilers provide all your central heating requirements and the boiler is sized against the number or radiators/ under floor heating and the total heat requirements for your home. Although with this system type a hot water storage cylinder is required to store the required hot water.


The cost for replacing an old boiler can vary house to house and also where in the UK you live and the availability of qualified professionals to fit the new boiler. The main variables to consider when considering the possible cost of a new boiler are, the existing type of heating system, the labour needed, whether the new boiler needs re-sitting in your home and how much remedial work is required.
