The 'Low or Zero Carbon Energy Sources: Strategic Guide (LZC)' supports the inclusion of low or zero carbon energy sources in Part L of the Building Regulations and Approved Documents L1A, L1B, L2A and L2B. Chapter 4 deals with micro-CHP.
As micro-CHP systems operate within the context of the building, the equipment, installation and testing must all comply with the relevant standards. Details of these standards are set out in full in the LZC guide.
The guide also sets out the factors to be considered for the purposes of calculating the potential of a micro-CHP system to contribute towards lowering the carbon dioxide emissions of a building in order for it to meet the compliance requirements of Part L.
Building regulations also apply to other aspects of the work such as electrical installation and plumbing work. It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to the relevant Competent Person Scheme.
