Ashford's Leading Air Pressure Testing Specialists!

Want to make sure your building meets Building Regulation L1a? At Tophouse Assessments, we specialise in assisting building companies, designers, architects, property builders and contractors across Ashford and Kent. 

There are many companies that will offer a takeaway Building Regulation L1a compliance service that ignores quality and focuses on cheap SAP calculations and air leakage testing. They therefore deliver weak and costly solutions that then require thousands of pounds spent on extra insulation or solar panels. These could easily have been avoided with more expertise; which is where we come in.

Working for domestic and commercial clients across Ashford and Kent, we quote fair and competitive prices that enable us to design and craft the very best air pressure testing and SAP calculation regimes. We utilise our decades of experience and expertise to explore the most cost effective ways of enabling you to meet building regulations for your conversions, new builds or extensions.

We aim to provide you with the very best compliance services, optimised to reduce your build costs while still enabling you to build better homes and domestic properties. Put your future builds in our experienced hands. Call Tophouse Assessments today on 01634 799115.
