If you’re involved in a new build or conversion project, you’ve likely come across the requirement for sound insulation testing. It’s a vital part of building compliance, helping ensure your development meets acoustic performance standards under Part E of the Building Regulations. But how much should you expect to pay – and what exactly is included?
In this guide, we’ll break down the typical sound insulation testing cost, explain the factors that affect pricing, and show you what to expect when you book a sound insulation test with Air Tightness Solutions.

What Is Sound Insulation Testing?
Sound insulation testing (also known as acoustic testing or sound testing) measures how effectively separating walls and floors reduce the transmission of airborne and impact noise between dwellings. It’s a legal requirement under Approved Document E for:
- New builds containing multiple dwellings (e.g. flats)
- Conversions where buildings are split into separate living units
- Semi-detached or terraced houses with shared walls
At Air Tightness Solutions, we provide UKAS-calibrated testing services to help ensure your property complies – and you get certified results you can rely on.
What Types of Sound Insulation Tests Are There?
There are two main types of sound insulation testing:
- Airborne Sound Tests – measure sound transmitted through the air (e.g. voices, music)
- Impact Sound Tests – measure structure-borne noise (e.g. footsteps on a floor)
Both are required under Part E for most developments.
Air Tightness Solutions offers both test types as part of our comprehensive service, delivered across the UK within 24 hours of booking.
Additional Acoustic Assessments
Certain property types — such as student accommodation, care homes, hospitals, and schools — may also require Environmental Acoustic Surveys, including Noise Sensitive Premises Assessments.
In contrast, commercial workplaces fall under the Control of Noise at Work Regulations 2005, which set limits on noise exposure for employees (e.g. max 87dB). If you’re unsure which regulations apply to your project, our team can advise.
