Condensing Boilers

The type and condition of your boiler is a major factor in its efficiency and therefore a modern condensing boiler will definitely save you money on your heating bills.

Important Information about changes to Building Regulations

From 1 April 2005, all new gas boilers fitted in England and Wales must be high-efficiency condensing boilers.

This change will not apply to oil-fired central-heating boilers until 1 April 2007. This change will not apply to warm air central heating.

You have probably heard about climate change and global warming being caused by the increasing amounts of carbon dioxide being released into the atmosphere. Around 16% of the carbon dioxide that the UK produces comes from the gas and oil boilers that we use to heat our homes.

This change is taking place because condensing boilers are more efficient, cost less to run and produce less carbon dioxide.

What is a high-efficiency condensing boiler?

Condensing boilers are high-efficiency boilers that produce less carbon dioxide. They reduce the amount of heat that escapes via the flue, compared with normal boilers. Condensing boilers also convert 86% or more of the fuel they use into heat and many carry the 'Energy Efficiency Recommended' logo.

When you change your old boiler for a condensing boiler, you will:

It is very easy to fit a high efficiency boiler. The only difference is that as an installer we also needs to fit a condensation pipe. However, there may be a few homes where it would too be difficult or expensive to do this. Your installer will be able to assess your home and if this is the case, we will be able to advise you on what type of boiler can be fitted instead.

Do I have to change my boiler now?

No. The new standards apply only if you decide to change your existing boiler.

Do I need to do anything now?

No, you do not need to do anything until you decide to have a new boiler fitted in your home.

Will I receive anything in writing when I have a new boiler installed?

From 1st April 2005, your local authority must be told when you have a new or replacement boiler fitted. Your installer should do this for you, and you should receive one of the following certificates: If your boiler is installed by a Gas Safe registered engineer, you will get a 'building regulations compliance' certificate from Gas Safe after the work has been completed. Gas Safe will tell the local authority that you have had a new or replacement boiler fitted.

You should keep these certificates as you may need them when you sell your home.

If an appliance has not been fitted by a Gas Safe registered engineer then the installer will not be able to register your appliance and therefore you will not get the certificate.
