London's Passivhaus Air Tightness Testing Specialists

Proven, accurate and first class passivhaus air tightness testing solutions across London.

While you might find other companies in the industry offering what we'd call 'takeaway' Building Regulation L1a compliance service that focuses on cheap air tightness testing, they consistently deliver costly and weak solutions that then require you to spend thousands of pounds on solar panels or increased insulation. These additional costs could easily have been avoided with more expertise; which is where London's experts at Tophouse Assessments comes in.

Working for designers, architects and builders across London and the South East, we only ever quote competitive and fair prices that enable us to craft and design the most accurate and best passivhaus air tightness testing solutions. Boasting extensive experience, we will explore the most cost effective ways of enabling you to meet all current Building Regulations for your passivhaus development.

As one of London's leading air tightness testing companies, we will provide you with the very best compliance services that are optimised to reduce your build costs and enable you to build better homes throughout the region. Call Tophouse Assessments today on 01634 799115.
