When it comes to building compliance, APT Sound Testing offers more than just a tick-box service. We provide a friendly, professional, and highly responsive approach to acoustic consultancy and compliance testing. Our mission is simple: to help clients across the UK meet regulatory requirements quickly, efficiently, and cost-effectively.
Whether you’re a self-builder working on a dream home or a large-scale developer overseeing complex projects, our team is here to support you every step of the way. With UKAS-accredited sound and air testing services, expert consultancy, and cutting-edge thermal imaging inspections, APT Sound Testing is a trusted partner for hundreds of clients in London and beyond.
Comprehensive UKAS Accredited Sound Testing
At the heart of our service offering is UKAS-accredited sound insulation testing, carried out in accordance with Approved Document E of the Building Regulations. This essential compliance testing applies to:
-
Residential buildings (new builds and conversions)
-
Commercial buildings
-
Schools and educational facilities
-
Any structures containing rooms for residential purposes (e.g. care homes, hotels)
Sound testing is critical to ensure that airborne and impact noise levels remain within acceptable limits. At APT, we not only test but also advise. Our experienced engineers are always on hand to offer practical acoustic design recommendations to improve performance and help our clients pass on the first attempt.
Experienced Engineers with a Proactive Mindset
What sets APT Sound Testing apart is our team of highly skilled and proactive engineers. With years of experience across sectors, we understand the challenges that can arise in real-world construction projects. We don’t just turn up and test, we work with you to overcome issues before they become problems.
Unlike many in the industry, we never subcontract our work. Everything is managed and executed by our in-house team. This means seamless coordination, high-quality standards, and faster turnaround times.
We’re also proud to offer dual UKAS accreditation for both sound and air tightness testing. This allows us to combine services in a single visit, cutting down on time, cost, and scheduling headaches for our clients.
Air Tightness Testing – Seamless & Efficient
Air leakage can have a significant impact on energy performance and regulatory compliance. Our in-house air tightness testing services are designed to complement our acoustic services, allowing us to deliver a comprehensive pre-completion package.
By offering both air and sound testing together, we reduce the need for multiple visits and streamline the certification process. This integrated approach is especially valued by developers working to tight timelines and budgets.
Advanced Thermal Imaging Inspections
In today’s energy-conscious world, understanding where a building is losing heat is more important than ever. Our thermal imaging surveys provide a non-invasive way to detect insulation defects, thermal bridges, air leaks, and more.
These inspections are valuable for both domestic and commercial clients, helping to:
-
Lower heating and cooling costs
-
Improve occupant comfort
-
Identify hidden structural issues
-
Boost health and safety through early detection
We always consider key environmental factors during thermal inspections, such as weather, wind speed, temperature differences, and building surface properties, to ensure the most accurate results.
