Part L 

With Part L of the Building Regulations driving the reduction of carbon emissions in buildings, the design and specification of the building fabric will have to be improved, whatever the fuel. If you are planning a private new build, it's good to know that compliance with Building Regulations Part L can be straightforward using the latest Dimplex heating systems, and that the standard required for compliance is achievable using electric heating systems.

As more of our electricity is generated using low carbon sources, and with the acknowledgement from DECC that electric heating plays a fundamental part in the objective of creating a low carbon world, gaining compliance with electric heating systems will get easier over time.

Building Regulations/Part L Compliance

In addition to designing schemes, the team also provides advice over the phone on complying with relevant building regulations, and over the years has helped many customers find a solution to their regulation nightmares.
