Airtightness testing for builders to cut energy use

We help builders across the UK with airtightness testing because getting it right first time saves stress, time and money. When air leaks out of a new build, it drives up heating bills, creates draughts and can lead to failed tests that delay handover. That’s why we plan early, walk the site with builders before the walls go up and offer advice to spot problems while they’re easy to fix. Testing only takes about an hour, and we’ll show you where leaks are if needed. We’ve done thousands of tests, and the ones that pass first time usually started with good prep.

EPC for New Builds Made Simple and Easy to Understand

When you build a new home, one of the key things you’ll need is something called an Energy Performance Certificate, or EPC. We help with this from start to finish, starting with SAP calculations, which are like a test on how well your home will use fuel and power. Once your build is complete, we check everything again and make sure your EPC gets logged properly. A good rating means lower bills and a cosier home, which is great for you or anyone looking to buy later. We’re here to help make the whole process simple and stress-free.

Most new builds in the UK need this test to meet Part L of the Building Regulations. If you’re building or renovating, we help you get ready, carry out the test and pinpoint any problems early.

Get SAP Air Tightness Certification UK with Our Help

SAP air tightness certification checks how well a home keeps warm air in and stops draughts getting through gaps and cracks. We test this by using a fan to push or pull air through the building and measure how much escapes. If too much leaks out, your house will be harder to heat and cost more to run. We help builders and homeowners across the UK get their homes ready to pass this test, offering advice along the way. Once it passes, you get a certificate which is part of what’s needed to meet building rules and get an Energy Performance Certificate.
