Building Regulation Part L Compliance Advice & Reports


Part L Compliance Checks are required for nearly all new buildings, including extensions with total useful floor areas greater than 100m2 and greater than 25% of the total useful floor area of the existing building.

New buildings are appraised in accordance with Approved Document L2 and awarded a PASS or FAIL.

In order to achieve a PASS buildings have to meet the following criteria:

  • Building Emission Rate must be less or equal to Target Emission Rate (BER<= TER)
  • Buildings should perform no worse than minimum standards (assessment of U-values, fixed services, lighting levels, air permeability of the building)
  • Buildings must not overheat in the summer

We are able to offer compliance checks on Non-Domestic Buildings in accordance with AD Part L2A or L2B.
