Gas-fired boilers installed after 1 April 2005 must be condensing boilers, whether they are replacements or new installations.
This is a requirement of the Building Regulations for England & Wales, Part L1 (Conservation of Fuel and Power).
In exceptional circumstances it is permissible to install a non-condensing boiler instead of a condensing boiler, provided that an assessment of the property by a competent person confirms that the additional cost of installing a condensing boiler is exceptionally high.
The assessor must identify the lowest additional cost for an installation anywhere in the building, irrespective of the boiler position chosen by the owner.
