You probably realise that if your boiler is getting on a bit, you could be burning hard earned cash on wasted energy. There are many “A” rated boilers available from from a range of different manufactures. What does “A” rated mean.Below is a graphic showing the SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK).

SEDBUK, boiler efficiency

The least efficient rating of “G” indicates an efficiency of 70% or less, thats if the old boiler is serviced regularly. A new “A” rated boiler offers a burning efficiency of 90% or above and could provide noticeable savings over the course of a year. It’s worth thinking about, your money is hard earned and its better in your pocket. A new boiler may not be as expensive as you may imagine.
