Changes to the Building Regulations for England and Wales, introduced in 2003, mean that new and converted residential developments must comply with stringent new sound insulation requrements.

The changes introduced a requirement for approved test bodies to carry out pre-completion testing (PCT) of actual sound insulation performance in many new and converted residences.

Approved Document E of the Building Regulations contains the required sound insulation standards with reference to noise indices such as DnT,w + Ctr and L’nT. Fortunately, our clients do not need to understand the complexities of these indices, as Hepworth Acoustics will deal with all of the technicalities of meeting the requirements.

Hepworth Acoustics provides a full service which can include checking the initial design for compliance with the Regulations and inspecting the construction to ensure that the sound insulation will be achieved in practice. This service will ensure that there are no surprises arising shortly before handover of the property.

Finally, we are approved under the Association of Noise Consultants Registration Scheme for carrying out sound insulation testing, so our reports and ANC certificates will keep the Building Control Officer happy and demonstrate compliance with the standards. Since 2003, we have carried out over 4,000 sound insulation tests, and on the rare occasion when we have not been involved at the design stage, and a construction has failed to meet the requirements, we have been able to recommend successful remedial works.
