Approved Document E: Resistance to sound

Statutory guidance · England-focused reference · Editorial source review:

Part E concerns resistance to sound in relevant residential buildings and schools. The applicable requirements and evidence depend on building use and whether the work is new construction or a conversion. Acoustic performance is affected by junctions and workmanship as well as the chosen wall or floor build-up.

Independent explanation, not an official approval or project-specific legal/design advice.

When to use this guide

  • Creating or converting flats or rooms for residential use
  • Specifying separating walls/floors or coordinating service penetrations
  • Planning acoustic evidence, inspection and any required testing

Keep these records

  • Acoustic design and junction information
  • Installation and pre-cover inspection records
  • Applicable test reports or other accepted evidence

Common mistakes

  • Relying on the rating of an isolated product as proof of the completed construction.
  • Assuming a detail suitable for a new building automatically suits a conversion.

When to get specialist help

Use competent acoustic advice where construction is unusual, noise transmission is uncertain or the proposed evidence route is unclear.

Scope and edition

Landing publication date 4 March 2015; confirm applicable edition and project-specific test/evidence route. Building use and work type affect the requirements. Do not assume one acoustic detail or test route suits every conversion or new building.

Sound insulation in dwelling-houses, flats, rooms for residential use and schools.

Use the official source to check the current text, amendments not yet incorporated, commencement and project-specific transition. A published future edition is not automatically the rule applying to your work.

About this library

Editorial source review: . Check the current official text, commencement dates, outstanding amendments and transitional arrangements before relying on a requirement. Publication date is not necessarily the date a rule applies. A relevant competent professional or authority must resolve project-specific questions.
