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.

Important notice
Along with many other businesses and brands around the world, 2020 has presented us with a number of challenges. Ensuring our customers and colleagues remain safe has been our top priority and to achieve this we have had to implement new ways of working, make changes to our production and customer services.
As our busy winter approaches, and with the continuing global situation, the impact can be seen in a number of ways:
- Extended call times to our teams on the telephone
- Longer than normal time to reply to email and customer enquiries
- Availability for certain products is based on our supply chain which can mean they are out of stock for an indeterminate period
- Delivery times on orders may be extended due to logistics and postal issues
- Delays or even the inability to carry out repairs to products.
We apologise for any issues this may cause you. We are committed to ensuring we look after our most vulnerable customers first, basing our replies on individual circumstances and those with total lack of heating.
Thank you for your patience - read our full update for more information and recommendations that may speed up how we can help you.
