Boiler legislation

In 2005 the Government changed the Building Regulations so that only gas or oil boilers of a specific efficiency could be installed. Furthermore, Boiler Plus Legislation was introduced on the 6th April 2018 and changed legislation around heating manufacture and installation in the UK.

Regulations since 2005

As of 2005, Building Regulations changed so that only gas or oil boilers of a specific efficiency could be installed, both for replacement and new installations.

A condensing boiler will need to safely dispose of condensed water within the building’s waste water system. However, there are circumstances where the only alternative is to run the pipe externally.

In this instance the pipe needs to be increased to have an internal diameter of at least 30mm and should be insulated, or supporting solutions such as internal insulation or trace heating products should be fitted to help prevent freezing.

New 2018 legislation

On the 6th April 2018 Boiler Plus Legislation was introduced to improve the energy efficiency of homes across the UK.

It stated that all gas boilers have to meet certain requirements which give consumers greater choice, greater control and tangible savings on their energy bills.

When installing a combination boiler, at least one of four additional energy saving measures must now be included:

  • Smart controls
  • Flue gas heat recovery
  • Weather compensation
  • Load compensation
