Don’t Get Caught Out — Why Air Text Measures Is Essential…
An air tightness test measures how much air leaks through gaps, cracks, and openings in your property. Uncontrolled air leakage can lead to significant heat loss, higher energy bills, and reduced comfort. Our test provides accurate data on how well your home or development retains heat, helping you comply with building standards and identify improvements that boost efficiency and comfort.

Improve your property’s energy efficiency and ensure building compliance with a professional Air Tightness Test. Our expert assessments help identify hidden air leaks, reduce heat loss, and improve overall comfort.
What an Air Tightness Test Identifies
- Draughts and hidden gaps– that allow warm air to escape.
- Heat loss through poorly sealed areas –including windows, doors, and service penetrations.
- Construction defects – that affect overall energy performance.
- Hidden air leakage areas – not visible through standard inspections. commercial buildings.
- Points of failure – that impact new-build compliance.
- Factors reducing efficiency – that limit the effectiveness of insulation and ventilation.
- Future technology limitations – issues that may affect systems like heat pumps.alid EPC to qualify.

In simple terms: no valid EPC can mean no sale, no tenancy, and possible penalties. Our job is to make sure that never becomes your problem.
Who Needs an EPC?
If you’re asking, “Do I need an EPC?” the answer is almost always yes if:
You’re a homeowner planning to sell or remortgage
You’re a landlord starting a new tenancy or renewing a tenancy
You’re a property manager dealing with multiple flats, houses or mixed-use buildings
You’re a developer with new-builds or conversions
You’re a professional advisor (estate agent, mortgage broker, solicitor) supporting clients who must stay compliant
If the building is being marketed for sale or rent, or has just been built or significantly altered, an EPC is almost always required.
Not sure? Tell us what you’re planning, and we’ll confirm whether you need one and what type.
How Does an EPC Assessment Work?
If you’ve never booked an EPC before, it can sound more complicated than it really is. Here’s how our process works from start to finish.
Step 1 – Get a Free, No-Obligation Quote
You share a few basic details:
Property type (house, flat, unit, etc.)
Size and number of floors
Location
Intended use (sale, let, remortgage, compliance check)
We’ll confirm a clear fixed price and offer you the earliest appointment.
Step 2 – Book Your Survey
We arrange a visit time that suits you. On the day, a qualified EPC assessor will:
Inspect walls, roofs, floors and windows
Check heating systems, boilers and controls
Look at lighting, insulation and hot water systems
Take measurements and photos for the report
Most surveys take 30–90 minutes, depending on the size and complexity of the building.
Step 3 – We Produce Your EPC
Back at the office, we enter all the data into accredited software. This generates your:
Energy rating (A–G)
Estimated energy costs
Recommended improvements
We then lodge your certificate on the official register and email you a digital copy.
Step 4 – We Explain the Results
If you’d like, we’ll walk you through:
What your rating means
Which recommendations are worth doing first
How upgrades could affect future ratings
You don’t just get a piece of paper — you get a clear plan.
