APT Sound Testing & Acoustic Design Services
When it comes to meeting acoustic requirements and building regulations, having the right expertise on your side makes all the difference. At APT Sound Testing, we provide comprehensive sound testing and acoustic design services for a wide range of projects across the UK.
Our work spans residential and commercial developments, as well as schools and buildings that include rooms for residential use. To make things even easier for our clients, we also offer in-house UKAS-accredited air tightness testing. By combining services into one seamless package, we help reduce costs, simplify project coordination, and keep everything running smoothly. All of our sound testing is carried out in accordance with Approved Document E of the Building Regulations.

Experienced Engineers, Reliable Results
Our team of skilled sound testing engineers is committed to delivering a high standard of service on every project. Beyond testing, we provide practical acoustic design advice to help clients achieve the required performance standards. This proactive approach not only supports compliance but also helps avoid costly delays when it comes to final approvals and building completion.
A Diverse Client Base
Over the years, we’ve worked with clients across both the public and private sectors. Our portfolio includes everyone from individual self-builders to major housing developers. We also support specialist environments such as cleanrooms, working with organisations in the healthcare and banking sectors.
What keeps clients coming back is our combination of technical expertise and a friendly, responsive service. In fact, we’re proud to have one of the highest return-client rates in the UK’s pre-completion testing and consultancy sector. Every project is handled entirely in-house—no subcontracting—ensuring consistency, quality, and accountability from start to finish.
Fast, Flexible, and Client-Focused
With a central London office and a well-resourced team, we’re able to respond quickly to testing and survey requests. We understand that construction timelines don’t always follow a 9–5 schedule, which is why we also offer short-notice bookings and weekend testing when required—something particularly valued in sectors like banking.
Our experience in acoustic design has helped us develop a deep understanding of both client needs and project challenges. As a multi-UKAS accredited laboratory operating to strict ISO standards, we deliver a dependable, high-quality service throughout every stage of the project lifecycle.
Practical Solutions, Modern Equipment
We take the time to understand each client’s requirements and provide practical, cost-effective solutions that also consider buildability. By integrating acoustic consultancy, design, and pre-completion testing into a single package, we streamline the entire process.
To ensure accuracy and efficiency, we use the latest UKAS-calibrated testing and survey equipment. Continuous investment in both our team and our technology allows us to maintain high standards and deliver reliable results every time.
