Air Tightness, Ventilation & Building Compliance Advice
This is where we share plain-English guidance on building performance, compliance, and energy efficiency — without the waffle.
Our blog covers the real issues we see on site every week, from air leakage and heat loss to ventilation, testing, and getting projects over the line without delays.
Whether you’re a builder, developer, retrofit professional, or a homeowner trying to understand what’s actually going on in your property, you’ll find clear explanations and practical takeaways here.
Nearly half of rental homes could fail the updated Decent Homes Standard - and expectations for landlords are tightening fast.

Failed a Part L air tightness test and not sure what’s gone wrong? You’re not alone. Most failures come down to small gaps across the building, not one big issue.

If your commercial energy costs are creeping up and you’re not sure why, you’re not alone. A business energy audit gives you a clear picture of how your building is actually performing — highlighting where heat is lost, where air is leaking, and what’s driving your costs. This guide explains what a commercial energy audit involves and how it helps you prioritise the right fixes, not just the obvious ones.
If your energy bills feel higher than they should be, you’re not alone. While rising prices play a part, the real issue is often how well your home holds onto heat. This guide explains why your gas and electricity bills might be so high, what “normal” looks like, and the hidden problems — like heat loss, air leakage, and ventilation — that could be driving your costs up behind the scenes.
A new build can look finished on the surface and still leak air in all the wrong places. Those hidden gaps can lead to failed tests, delays, and costly rework — or cold, uncomfortable homes with higher energy bills. This guide explains what causes air leaks in new builds, where they typically occur, and how they’re accurately found, so you can fix the real problem early and keep your project on track.
If your home or building feels cold, drafty, or just not performing as it should, the issue usually comes down to heat loss, air leakage, or ventilation. The challenge is knowing what to test — and why. This guide breaks down the different types of building energy assessments in plain English, so you can understand what each one actually tells you and choose the right approach before spending money on the wrong fixes.
