Our ventilation testing service helps you comply with part F of the building regulations that is key to the completion of any new building development.

As air tightness in buildings improves, so too must the ventilation, in order to prevent the build-up of black mould. We often carry out ventilation testing at the same time as air tightness tests to keep costs as low as possible for housebuilders.

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 ventilation testing.

Quality

We consistently provide exceptional service to help clients pass their ventilation test on the first visit. 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.

Who We Work With

Ventilation testing plays a vital part in many building projects. Here’s a brief introduction to the most common variations. 

Part F Ventilation Testing

Ventilation testing is a requirement under part F of the building regulations for all new property developments and is normally carried out right at the end of the project, just before residents move in.  While all new build dwellings require a Part F ventilation test, building control does not always ask for it. 

MVHR Commissioning

Mechanical Ventilation with Heat Recovery (MVHR) systems are increasingly being used in energy-efficient buildings as they can be calibrated to use very little electricity. This calibration, called MVHR commissioning, needs to be carried out by an experienced air tester.

MVHR commissioning involves testing and adjusting the fan speed in each fan unit to optimise its performance. Fan flow rates need to be recorded before the system can be certified.

Our engineers are experienced in both types of ventilation testing and can advise on the best approach for your project.
