Building air leakage testing UK
Air Tightness

Building air leakage testing UK helps keep homes warm

We test how much air leaks in or out of a building when it’s meant to be sealed up tight. This matters because if too much air escapes, your heating or cooling has to work harder, meaning higher bills and more stress down the line. At Ratio Seven, we help builders, developers and homeowners across the UK check their buildings meet the rules set out in Building Regulations Part L. We make the process simple by finding hidden gaps and explaining everything clearly, so you can fix small problems early and avoid costly delays later. Ready to book or ask questions? We’re here to help.

Certified Air Pressure Testing UK Helps Keep Homes Airtight

We get asked all the time what air pressure testing is and why it’s needed, so here’s the easy answer: it checks how much air leaks from your building. Too many gaps make your home cold and expensive to heat, and it can even stop you from passing building regulations. We use special fans and equipment to find where the leaks are, then help you fix them if needed. The test helps with your energy rating too, which means lower bills and a warmer home. At Ratio Seven, we make the whole thing simple from start to finish and guide you every step.

Whether you’re planning a new home or fixing up an older one, we spot issues early so you don’t waste time or money. We keep things simple, clear and focused, so your build stays on track without any nasty surprises or last-minute stress.

When you’re starting a building project in the UK, getting the right advice on building rules early on can save headaches later.

We take the stress out of it by reviewing your plans, finding any issues, and working with your team to fix them before build time. Whether you’re building from scratch or improving what you’ve got, we make sure it all lines up with what building control needs to see.

How Domestic Energy Assessments UK Work with SAP Ratings

When you're building or selling a home in the UK, you’ll probably hear about SAP assessments and they can sound a bit confusing at first. We help people understand what they mean and why they matter. A SAP assessment looks at how much energy a home will use and gives it a score, which then turns into the letter rating you see on an EPC (A to G). We work with builders and homeowners across the country to guide you through the steps, help you meet building rules, and make sure your home is built to be warmer, greener and cheaper to run.
