How much can you save with energy efficient boilers ...

Boilers account for around 60% of all domestic CO2 emissions according to the Energy Saving Trust.

So it's no surprise that one of the most effective ways of reducing your energy bills is to replace an old or inefficient boiler, generally those over 15 years old. All modern boiler systems are designed to be energy efficient and need less fuel to run with the most efficient condensing boilers using 30-40% less.

Installing a new boiler is expensive but the savings you could make through lower heating bills can help you recover the cost within 3-5 years and the savings would continue long after. Even so, there may be grants available in your area to help you with the cost of purchase and installation. Contact your local Energy Saving Trust Advice Centre on 0800 512012 for more details.

How to buy a high efficiency condensing boiler?

You could first contact your local Energy Saving Trust Advice Centre for information on any grants that are available and a list of approved installers.

You should also check that the installer is an approved member of either CORGI for gas appliances, or OFTEC for oil fired appliances. For gas-fired boilers contact a local CORGI registered installer or for oil-fired boilers contact OFTEC.

When choosing a particular make and model, look out for the Energy Saving Recommended logo and bear in mind that boilers are rated according to how much of the fuel they consume is converted to heat, as a percentage. This rating is called SEDBUK or Seasonal Efficiency of Domestic Boilers in the UK. These ratings are from A to G with A-rated boilers being more than 90% efficient.
