About APT Sound Testing in London
At APT Sound Testing, we deliver UKAS-accredited sound testing services across London and throughout the UK, helping developers and building professionals meet the requirements of Approved Document E of the Building Regulations. Our expertise spans residential and commercial developments, schools, and buildings containing rooms for residential purposes — ensuring every project achieves the acoustic standards required for completion.
Comprehensive Acoustic Testing & Consultancy
Our experienced team of sound test engineers is committed to delivering exceptional service at every stage of your project. Beyond testing, we provide practical acoustic design advice to help you achieve compliance efficiently and cost-effectively. By identifying potential issues early, we support our clients in securing a smooth path to passing sound insulation testing and achieving building sign-off.
To make the process even more seamless, we also offer UKAS-accredited air tightness testing in-house. By combining services under one roof, we reduce costs, eliminate coordination challenges, and simplify project management.
Trusted by Clients Across Sectors
With many years of industry experience, we support a diverse client base across both public and private sectors. From self-builders and independent developers to some of the UK’s largest housing providers, our team has built long-standing relationships based on reliability and results. We also work with healthcare authorities and financial institutions, delivering specialist cleanroom testing where precision and compliance are critical.
Our proactive approach and friendly service have earned us one of the highest return-client rates in the UK’s pre-completion testing and consultancy sector. Every project is handled entirely in-house — we never subcontract — giving you confidence in the consistency and quality of our work.
Fast Response, Flexible Service
As one of the few acoustic consultancies with a central London office, we’re perfectly positioned to respond quickly to survey and testing requirements. We understand that construction timelines can change at short notice, which is why we have the capacity to accommodate last-minute testing and weekend working when required — a service particularly valued in sectors such as banking and commercial fit-outs.
Quality Assured from Start to Finish
Our highly trained engineers use the latest UKAS-calibrated acoustic testing equipment, ensuring accurate and reliable results every time. As a multi-UKAS accredited laboratory operating to strict ISO standards, we maintain the highest levels of quality assurance throughout every stage of the project lifecycle.
Continuous investment in both our people and technology enables us to deliver an efficient, responsive service focused on customer satisfaction. We take the time to understand each client’s needs and offer practical, buildable, and cost-effective solutions that integrate acoustic design and pre-completion testing into one streamlined package.
