Tonbridge's Air Tightness Testing Experts

Proven, accurate and first class air leakage and pressure testing and SAP calculations for clients across Tonbridge and Kent.

While there are a variety of companies in the industry that offer what could best be called a 'takeaway' Building Regulation Part L1a compliance service that focuses on cheap SAP calculations and air tightness testing, they consistently deliver costly and weak solutions that then require thousands of pounds to be spent on extra insulation or solar panels. These additional costs could easily have been avoided with more expertise; which is where Tophouse Assessments comes in.

Working for designers, architects and builders across Tonbridge and Kent, we quote competitive and fair prices that enable us to design and craft the most accurate and very best SAP calculations and air pressure testing. Boasting decades of experience, we will explore the most effective ways of enabling you to meet all Building Regulations for your conversions, new builds or extensions. 

As one of London and Kent's leading air tightness and pressure testing companies, we will provide you with the very best compliance services that are perfectly optimised to reduce your build costs and allow you to build better homes throughout Tonbridge and Kent.
