Sound insulation testing measures exactly how well walls and floors reduce the transfer of noise between attached homes, flats, or commercial spaces. If your building has separating walls or floors between different dwellings, this test is usually a strict legal requirement before handover.
Our comprehensive acoustic testing checks two distinct types of noise transmission:
The final results determine whether your construction successfully meets the rigorous standards set out in Approved Document E (Part E) of the Building Regulations. Ultimately, it’s an essential part of creating homes that are quiet, private, and comfortable for everyone living there.
Book Your Acoustic Test Today →Passing your acoustic test is not just about avoiding fines; it's about protecting property value and ensuring occupant well-being.
Provides the mandatory legal proof required by Building Control that your construction meets the acoustic standards of Approved Document E.
Verifies that the separating walls and floors physically installed on site actually deliver the acoustic performance promised in the design stage.
Protects future occupants from unwanted noise transmission, guaranteeing privacy and dramatically reducing the likelihood of neighbourly disputes.
A pass certificate is an essential document in your handover pack, allowing the swift progression of your building's sale or rental processes.
Demonstrating robust, high-quality acoustic construction makes a property significantly more attractive and valuable to prospective buyers or tenants.
Identifying acoustic failures before occupants move in allows for targeted remedial action, saving you from disastrously expensive retrospective fixes later.
We make acoustic testing straightforward, providing expert support from the moment you book until your certificate is issued.
We carry out tests using UKAS-calibrated equipment—including high-powered loudspeakers, precise tapping machines, and sensitive microphones—to check sound levels accurately.
Acoustic data can be complex. Our team explains the results in clear, simple terms immediately on site, so you know exactly where your project stands.
If your property fails to meet the required decibel targets, we don't just leave. We provide instant, expert advice on how to locate the acoustic leak and fix the issue.
We offer flexible scheduling to meet your project timeline. Upon passing, you’ll receive a detailed, UKAS-accredited certificate accepted by Building Control nationwide.
Securing your Building Control sign-off relies heavily on Pre-Completion Testing (PCT). Under the latest updates to the UK Building Regulations, demonstrating robust sound insulation between newly attached dwellings is non-negotiable.
Building Control requires testing for two completely different physical phenomena to ensure full acoustic comfort for the end-user.
Conducted on both separating walls and separating floors. We use a powerful omni-directional speaker to generate steady 'pink noise' (around 100dB) in a source room. We then measure how much of that specific noise frequency transfers through the wall or floor into the adjoining receiver room.
Conducted only on separating floors. We use a specialized, calibrated tapping machine that drops small metal hammers onto the floor structure. Microphones in the room directly below measure the transmitted vibration noise, simulating the sound of heavy footsteps or dragged furniture.
Before we arrive on site, your building must be in an appropriate condition. All doors and windows must be fitted and fully sealable. The rooms must be completely empty of furniture, and critically, no cosmetic floor coverings (like carpet or laminate) should be installed before the impact test, as these artificially inflate the pass score.
Acoustic tests don't fail randomly. The vast majority of Part E failures stem from construction detailing errors rather than poor material choices:
Sound travels around the separating wall through shared structural elements, like a continuous floor joist or unsealed blockwork cavity.
Plumbing pipes, HVAC ducts, or electrical sockets installed back-to-back across a separating wall create a direct tunnel for airborne noise.
If a resilient acoustic floor layer is accidentally nailed down or bridged by a rigid skirting board, impact sound will bypass the insulation entirely.
Internal doors leading to shared corridors lacking proper acoustic drop seals or heavy-duty fire strips will leak substantial airborne noise.
We handle complex acoustic testing for developers across London and the UK.
