Guildford's Most Accurate Air Pressure Testing

High quality, affordable and trusted SAP calculations and air pressure testing across Guildford.

While you will find various companies across the industry that offer a 'takeaway' Building Regulation L1a compliance service that focused on cheap SAP calculations and air leakage testing, they consistently deliver costly and weak solutions that lead to you spending thousands of pounds on extra insulation or solar panels. These additional costs could easily have been avoided with more expertise; which is where we at Tophouse Assessments comes in.

We will explore the most effective and reliable ways of ensuring that you meet all current Building Regulations for your new builds, extensions or conversions. So call Guildford's specialists in air leakage testing and SAP calculations at Tophouse Assessments today on 01634 799115.
