Sevenoaks' Leading Air Tightness Testing Experts

Working across Sevenoaks and Kent, we specialise in helping architects, designers, property builders, contractors and building companies to meet Building Regulation L1a for new properties and homes. 

There are a variety of companies across Kent and the rest of the UK that offer a 'takeaway' Building Regulation L1a compliance service that focuses on and provides cheap SAP calculations and air leakage testing. However, they deliver potentially costly and weak solutions that then require thousands of pounds spent on extra insulation or solar panels. These could all be avoided with more air pressure testing expertise, which is where Tophouse Assessments comes in.

Working for clients throughout Sevenoaks and Kent, we design and craft the most successful and very best SAP calculation and air tightness testing regimes for very fair prices. Utilising our extensive experience in the industry, we explore the most effective and reliable ways of enabling you to meet building regulations for your extensions, new builds and conversions.

We will provide you with the very best compliance services optimised to reduce your build costs - and still enable you to build better homes across Sevenoaks and Kent. So put your future builds in our expert hands and call Tophouse Assessments today on 01634 799115.
