BREEAM acoustics: the credits, secured.

Post-construction measurement in a sample of finished rooms: airborne sound insulation between spaces, indoor ambient noise levels, and reverberation time where the building type calls for it. The results are compared against the criteria for your building (BS 8233:2014 for offices, BB93:2015 for schools, HTM 08-01 for healthcare) and the measurements must be made by a suitably qualified acoustician. The results feed straight into the post-construction evidence pack.

Pol 05 (“reduction of noise pollution”) deals with the noise your new building makes. Where there are noise-sensitive premises near the site, it requires a noise impact assessment following BS 4142, comparing plant noise from the development against the existing background sound level. If the rating level is too high, attenuation measures are required, which is why it pays to check plant selections before they're purchased, not after.

Yes. Both Hea 05 and Pol 05 require the assessment and measurement work to be carried out by a suitably qualified acoustician: someone with a recognised acoustics qualification and corporate membership of the Institute of Acoustics, plus relevant experience. Murray Acoustics meets that definition, so the appointment covers the compliance requirement as well as the technical work.

When the pre-assessment is being put together, typically at RIBA Stage 2 or 3. Design-stage certification needs design-stage evidence, and the credits are far cheaper to secure while constructions and plant selections can still change. The final measurements need finished, quiet rooms, so testing is booked near practical completion, and the report lands within five working days of the survey.

Every project is a fixed fee agreed up front, so we don't publish a price list. Send the pre-assessment or the credit target and a brief description of the building and we'll come straight back with a figure covering design review, testing and evidence. No day rates, no surprises.

Yes. WELL v2's Sound concept covers sound mapping, maximum noise levels, reverberation time and sound-reducing surfaces, among other features. The work is the same shape as BREEAM: design review against the thresholds, then measurement for performance verification. We prepare the documentation your WELL reviewer needs.
