Building Regulations

Building Regulation Part ‘L’

building regulations

Dwellings account for 27% of the UK’s carbon dioxide emissions and Government is committed to reducing them and to reduced energy consumption via a number of initiatives to reduce Global Warming. Part ‘L’ – Conservation of Fuel and Power – of the Building Regulations are the mechanism by which these intended reductions will be achieved. Dwellings and extensions constructed to current Building Regulations will comply with Part ‘L’ requirements and will already have a good standard of thermal insulation.

If you are having a new house or an extension built your architect, or other qualified agent, will have to submit an application for Building Regulations Approval to the Local Authority’s Building Control Service.

This submission must contain a Standard Assessment Procedure (SAP) calculation to assess the energy performance of the dwelling based on its characteristics and systems installed. The indicators of the energy performance are energy consumption per unit floor area, an energy cost rating (the SAP rating), an Environmental Impact rating based on carbon dioxide emissions and a Dwelling Carbon Dioxide Emission Rate (DER).

Modern electric heating systems are 100% compatible with Part ‘L’ requirements. Electric underfloor and ceiling heating systems are permitted under National Standards, Part ‘L’ of the Building Regulations, NHBC guidelines, policy initiative PPS 22. TEHVA (The Electric Heating and Ventilation Association) provides guidance to specifiers and designers of electric heating systems in the form of Document DOM 8 (Guidance to the Design of Electric Space Heating Systems).
