Do you cover Warwick, Leamington Spa and Stratford?

Yes. We cover the whole of Warwickshire including Warwick, Royal Leamington Spa, Stratford-upon-Avon, Rugby, Nuneaton, Kenilworth, Bedworth, and Southam. Warwickshire sits between our Worcester base and the West Midlands conurbation, so we travel through the county regularly and maintain regular testing slots.

Sound insulation testing in Warwickshire

Accredited Part E testing across Warwickshire — from Warwick to Rugby.

Sound insulation testing equipment in Warwickshire

Warwickshire sits between our Worcester base and the West Midlands conurbation, making it one of our most accessible testing areas. With a mix of new build housing estates, apartment developments, and period property conversions across the county, we maintain regular testing slots and can often accommodate same-week bookings.

Sound insulation testing measures how effectively separating walls and floors prevent sound from passing between adjoining dwellings. Airborne tests measure speech and music transmission (DnT,w + Ctr in dB); impact tests measure footstep noise through floors (L’nT,w in dB).

Part E of the Building Regulations requires all new build attached dwellings, apartments, and material change-of-use conversions to demonstrate acceptable sound insulation before building control sign-off.

Beyond compliance, good sound insulation is one of the strongest predictors of resident satisfaction. Flanking transmission, poor junction detailing, and incomplete acoustic barriers are the most common causes of failure — all preventable with design-stage decisions and quality control.

Part E minimum standards

≥ 45 dB

DnT,w + Ctr airborne — new build

≤ 62 dB impact L’nT,w for separating floors between apartments. Conversions have a relaxed airborne standard of 43 dB DnT,w + Ctr.

Scope confirmation. We confirm exactly which walls and floors require testing based on your development type, layout, and the number of units — before you book.

The test process

What happens on the day of your sound test.

A typical sound test takes between two and four hours on site.

Site readiness check

We walk the building with your site team, confirming that separating walls and floors are complete, rooms are accessible on both sides, and no construction activity is underway that could affect results.

Airborne wall tests

A calibrated loudspeaker generates broadband noise in the source room. Sound levels are measured in both source and receiving rooms to calculate the sound reduction index across the separating wall.

Floor tests — airborne & impact

For apartments, airborne floor tests use the same loudspeaker method. Impact tests use a standard tapping machine on the upper floor while sound levels are measured in the room below.

Report & certificate

Test report issued within 24 hours. If the building passes, a compliance certificate is provided for Building Control submission. If it fails, we provide guidance on remediation and arrange a re-test.

Preparation

Getting your build ready — and avoiding a re-test.

Sound insulation tests are highly sensitive to the condition of separating elements and surrounding finishes. Incomplete plasterwork, missing acoustic membranes, or unsealed service penetrations can all cause a failure that would have been avoided with a finished build.

No floor coverings should be laid on separating floors before testing. Carpet and underlay can artificially improve impact test results, and Building Control will not accept results taken with coverings in place. Hard flooring can remain if it is the permanent finish.

We provide a pre-booking checklist at the point of enquiry so your site team can confirm readiness before we attend. This avoids wasted visits and re-test costs.

FAQ

Common questions about sound insulation testing in Warwickshire.

It depends on your development type. All separating walls require airborne testing. Separating floors between apartments require both airborne and impact tests. Houses with separating walls only (terraced or semi-detached) require airborne wall tests only.

If you're unsure which tests apply, contact us and we'll confirm based on your building type and layout.

If a test fails, our report will include the measured result, the shortfall against the required standard, and guidance on the most likely causes. Common reasons include flanking transmission, unsealed gaps around service penetrations, incomplete skimming of party walls, or missing acoustic membranes.

In most cases we can advise on targeted remedial measures that don't require demolition of the separating element. Once remediation is complete, a re-test is arranged.

Yes — this is something we actively encourage for developments that require both tests. Combining air tightness and sound insulation testing on the same site visit reduces programme disruption, cuts travel costs, and means fewer site attendances overall.

Yes. We test all Part E development types in Warwickshire, including material change-of-use conversions. Conversions have a slightly relaxed minimum standard of 43 dB DnT,w + Ctr for airborne tests (compared to 45 dB for new builds) to account for the constraints of working within an existing structure.

The test methodology and preparation requirements are the same.

Yes. We cover the whole of Warwickshire including Warwick, Royal Leamington Spa, Stratford-upon-Avon, Rugby, Nuneaton, Kenilworth, Bedworth, and Southam. We travel through the county regularly and maintain regular testing slots across all areas.

Warwickshire is close to our Worcester base and well within our core service area. We typically have same-week availability and can often accommodate short-notice bookings. Contact us on 01386 365145 to check current availability.

A standard set of tests for a typical pair of semi-detached or terraced houses — two airborne wall tests — usually takes around two hours on site. For an apartment block requiring airborne wall tests, airborne floor tests, and impact tests, allow a full working day depending on the number of units.
