Passive House is an approach to building design that sets the highest standards of energy efficiency in the world. Ensuring the building envelope is airtight plays a key role in this, requiring more air tightness tests to be carried out using a more rigorous methodology than for standard properties. 

Our local passive house air testing engineers are always delighted to work on Passive House projects because the end product – a super energy-efficient, airtight building – has a higher energy performance than a typical property.

Also referred to as “Passivhaus”, or low energy air tightness testing, the main variations between a normal project and a Passive House one include the standards set (you need to achieve far lower air leakage scores), the process followed (the building must be pressurised, then depressurised), and the number of tests required (at least three tests must be carried out along the construction timeline).

Why work with us?

Experience

Our testing engineers have over 25 years of combined experience, with thousands of tests under our belts.

There is not much we haven’t seen, meaning that we can provide on-site advice on every aspect of air tightness testing.

Quality

We consistently provide exceptional service to help clients pass their air test on the first visit, offering our knowledge to help them find leaks in their buildings and rectify any issues.

If your property is unlikely to pass, we will advise on how to fix this.

Speed

Our office-based staff work hard to book all appointments as quickly as the delivery schedule allows.

95% of all tests take place within two weeks of the initial booking, with the majority of certificates provided within 24 hours of the site visit.

Pricing

Our rate card prices for all services are reviewed regularly, so we’re confident that you won’t find a better service for a better price anywhere else.

If you think you’ve found one, we’ll either beat or match it.

Support

Navigating the complexity of energy efficiency, decarbonisation, and building regulation updates isn’t easy. We’ve worked hard to explain a range of topics related to building testing in plain English to help non-experts get the information they need.
