We'll Help Your London Property Meet Building Regulations L1A and L1B

New building site in LondonWorking across London, we specialise in the assessment of existing and new buildings for Building Regulations parts L1A and L1B.

With building regulations changing every year and getting stricter and stricter when it comes to fabric energy efficiency and air leakages, it's vitally important to have your London buildings assessed by experienced professionals.

Building regulations across London are now set so low that innovative and new technologies and designs are required to ensure that the dwellings pass.  

At Tophouse Assessments, we combine decades of building and construction expertise and experience with full certifications and qualifications to accurately assess your London building design to the latest building regulations L1A and L1B. We also work closely with London architects and designers from the initial stage of the project to ensure the building complies.

We work across London, so call our experienced and qualified team today on 01634 799115 for free building regulations Part L advice and a no obligation quotation.
