At Tophouse Assessments, we specialise in assisting designers, property builders, building companies, contractors and architects from across Portsmouth and Hampshire to meet all building regulations during their construction projects.

Sure, there are many companies out there that will offer you a fast Building Regulation L1a compliance service that ignores quality and focuses on cheap air leakage testing and SAP calculations. They deliver weak and extremely costly solutions that, at a later date, require thousands of pounds spent on solar panels or extra insulation. These could easily be avoided by hiring a company with more expertise. So why settle?
