Building Regulation Part L Condensing Boilers

All new and replacement boilers in homes should now be of the condensing type, if it is appropriate for your property. A simple procedure will determine whether a condensing boiler can be fitted. This involves assessing the installation along with:

• The property type
• The fuel
• Whether the boiler needs to be moved
• The need for an extended flue
• The need for a condensing pump or soak-away

All gas boilers must be installed by a CORGI registered installer who will advise you whether a condensing boiler is appropriate for your property and provide you with a declaration form for you to keep. (An OFTEC installer will advise you for oil fired boilers). You should keep this form.

This came into force on 1 April 2005 for gas boilers and comes into force on 1 April 2007 for oil fired boilers.

Condensing boilers are more efficient than the conventional type and are available in standard and combination models. Better efficiency means that your heating bills will be reduced.
