Acoustic Testing helps you demonstrate compliance with the sound insulation requirements that apply to your development before completion – delivered through our trusted ANC-accredited testing partner.

Pre-completion sound insulation testing is a legal requirement for newly built dwellings, conversions and residential units such as flats, hotels and care homes – governed by Approved Document E in England and Wales, Section 5 in Scotland and Technical Booklet G in Northern Ireland. Testing must be carried out by a suitably qualified, accredited acoustic consultant, and the results directly affect Building Control sign-off – get it wrong, or leave it too late in the build programme, and it can hold up completion.

We don’t carry out acoustic testing directly – instead, we refer this work to our trusted partner organisation, Acoustic Consultants, registered under the Association of Noise Consultants (ANC) accredited scheme, in the same way they refer air tightness testing work to us. It means you get specialist, accredited acoustic testing without having to source and vet a separate consultant yourself.

Why work with us?

Experience

We work with Acoustic Consultants, a long-standing, ANC-accredited testing partner for all acoustic testing referrals, in a reciprocal relationship – they refer their air tightness testing needs to us in turn. It means you’re introduced to a consultant we know and trust, not an unknown name from a search result.

Blake Lucas, Director at Acoustic Consultants – Air tightness testing

What is acoustic testing, and when is it required?

Acoustic testing (pre-completion sound insulation testing) is a legal requirement for newly built dwellings, conversions, and residential units such as flats, hotels and care homes. It confirms that party walls and floors meet the sound insulation standards set out in Approved Document E (England & Wales), Section 5 of the Building Standards (Scotland) or Technical Booklet G (Northern Ireland) before Building Control will sign off the development.

What performance standards does the test need to meet?

New Build (walls & floors): airborne sound insulation must achieve a minimum of 45 dB DnT,w+Ctr (higher is better), and impact sound insulation must not exceed 62 dB L’nT,w (lower is better).

Conversion / Material Change of Use: airborne sound insulation must achieve a minimum of 43 dB DnT,w+Ctr (higher is better), and impact sound insulation must not exceed 64 dB L’nT,w (lower is better).

What do the tests actually measure?

Tests cover two types of sound: airborne sound (speech, TV, general noise) transmitted through party walls and floors and impact sound (footsteps, moving furniture) transmitted through party floors, measured using a calibrated tapping machine.

How many tests will my development need?

Standard regulations require one set of tests for every 10 units in a group or sub-group. A standard test set generally includes 2 airborne wall tests, 2 airborne floor tests and 2 impact floor tests between habitable rooms.

When on-site does testing need to happen?

Testing must take place pre-completion once the building envelope is fully sealed (walls plastered, internal and external doors and windows fitted, power operational) but before soft floor coverings such as carpets, laminate or underlay go down.

Who’s qualified to carry out the test, can I do it myself?

Building Control only accepts results from a qualified acoustic consultant accredited through UKAS or the ANC Registration Scheme – our partner, Acoustic Consultants, is registered under the latter.
