From 1 July 2015, there are changes to Building Regulations in relation to sound transmission between dwellings.
Transition Arrangements: This change applies to works, or buildings in which a material change of use takes place, where the works or the change of use commence or takes place, as the case may be on or after 1 July 2015. Technical Guidance Document E – Sound dated 1997, also ceases to have effect from that date.

Important points to note:
- This does not just apply to new buildings. Extensions, changes of use and material alterations must comply with the new standard and be tested.
- In the case of material alterations or changes of use to protected structures, an acoustic assessment of the existing structure should be carried out, including a sound insulation test and an expert may have to be employed.
- Testing has to be carried out at completion by a competent tester.
- Testing should be carried out on a proportion of dwellings on development sites as part of the construction process. Guidance on this is included. (Note: Certifiers may find that this is not adequate as they have to provide a separate Certificate of Compliance (Completion) for each dwelling).
- Construction details for masonry and timber framed party walls and floors are included in the new TGD.
- The design of building services, their position in the building and the building structure should be considered at an early stage in the design process, to reduce their impact on occupants of apartment buildings.
- The layout of buildings and position of rooms should be considered carefully at an early design stage.
- Lightweight structures need special consideration and it may be appropriate to support noisy plant on a separate, rigid structure.
