Energy Efficiency Testing & Reporting
If you’re working to tight deadlines on a new development, managing retrofit projects under PAS 2035 or the ECO4 scheme, or just trying to cut energy bills at home, you need testing you can trust.
AVT UK’s UKAS-certified team combines airtightness testing, ventilation compliance assessments and ultrasonic air leak detection into one complete energy assessment, giving you a clear picture of how your building really performs — and where it can do better.
- Developers get verified data for Part L and EPC testing without costly delays.
- Retrofit teams get the proof they need for compliance and funding.
- Homeowners see exactly where their property loses heat and how to make it more efficient.
Fast, clear, and straightforward from start to finish.
Who Energy Efficiency Testing Helps
Our energy assessment and reporting services support every stage of the build or retrofit process — helping you stay compliant, save time, and make measurable progress toward better energy conservation.
- Developers: Keep projects moving with quick, compliant testing that supports building energy ratings, EPC requirements, and Building Control approval — avoiding delays and costly rework.
- Retrofit teams: Get the verified data you need to meet PAS 2035 and ECO4 scheme standards. Our reports provide solid proof that your work meets modern efficiency expectations.
- Homeowners: See how your home energy performance stacks up and where you can save energy. From spotting heat loss to improving ventilation, our reports give you simple, practical ways to cut costs and improve comfort.
Our results are trusted by retrofit coordinators, energy assessors, and Building Control inspectors — giving everyone reliable data for confident, accurate sign-off.
What Is an Energy Efficiency Test
An energy efficiency test measures how well a building holds heat, moves air, and prevents unnecessary energy loss.
It combines airtightness checks, insulation analysis, and ventilation testing into a single energy assessment, giving you a clear picture of real-world performance.
That data becomes a straightforward, actionable energy efficiency report showing where your building performs well and where improvements could save energy, reduce costs, or boost its building energy rating.
If you’re a developer, you’ll get verified results for Part L and EPC compliance — cutting the risk of retesting and project delays.
If you’re part of a retrofit team, you’ll have the evidence you need for PAS 2035 and ECO4 submissions, ready to prove compliance without the paperwork stress.
And if you’re a homeowner, we’ll help you see how your home uses energy — and where a few simple tweaks to insulation or ventilation could make it warmer, cheaper to run, and far more comfortable.
Every energy efficiency test follows UKAS standards, feeding directly into EPC calculations and regulatory compliance.
The result is clear, factual insight that helps you stay efficient and in control of your energy usage.
Why Energy Performance Testing Matters
Energy performance isn’t just about ticking compliance boxes — it’s about cost, comfort, and carbon.
If you’re a developer, poor data can lead to failed Part L sign-off and expensive project delays.
If you work in retrofit, weak evidence can hold up ECO4 funding or fail PAS 2035 checks.
And if you’re a homeowner, it’s a chance to see where your home’s working well — and where small changes could make it warmer, cheaper to run, and more efficient.
Our energy efficiency testing and reporting helps you avoid those problems by giving you verified, easy-to-understand results. You can use the data to:
- Support EPC certification and energy performance certificate tests
- Demonstrate compliance for ECO4 retrofit projects
- Improve energy conservation and building energy ratings across your property portfolio
Good data leads to good decisions — it’s how you cut waste, save energy, and create buildings that feel better to live or work in.
