What is Building Regulations Approved Document E?

Building Regulations Approved Document E relates to the sound insulation and acoustic performance of buildings in the UK. It provides guidance on how to meet the legal requirements for sound insulation between dwellings, as well as between different parts of a building, to ensure adequate protection against noise.

The document outlines the performance standards for airborne and impact sound insulation, and it offers recommendations for construction methods, materials, and testing procedures to achieve these standards. It applies to new buildings, conversions, and certain alterations to existing structures, aiming to create a comfortable living environment by minimizing noise disturbance.

Why is Building Regulations Approved Document E important?

Building Regulations Approved Document E is important for several reasons:

1. Noise Control: It establishes standards for sound insulation, helping to reduce noise pollution between dwellings and different areas within buildings, promoting a more comfortable living environment.

2. Health and Wellbeing: Excessive noise can negatively impact physical and mental health. By regulating sound insulation, the document helps ensure residents’ peace and comfort.

3. Quality of Life: Good acoustic design enhances the overall quality of life for occupants, making homes and buildings more enjoyable and functional.

4. Legal Compliance: Following the guidelines in Document E is essential for compliance with building regulations, which is a legal requirement in the UK. Non-compliance can lead to penalties or issues when selling properties.

5. Market Value: Properties with good sound insulation may have a higher market value, as potential buyers often prioritize noise control in their decision-making.

6. Construction Standards: The document provides a framework for builders, architects, and designers, ensuring that sound insulation is considered during the planning and construction phases.

Is Building Regulations Approved Document E a legal requirement?

Yes, Building Regulations Approved Document E is a legal requirement in England and Wales. It provides guidance on how to comply with the legal standards for sound insulation in buildings, as laid out in Part E of the Building Regulations 2010.

Approved Document E specifically deals with the resistance to the passage of sound in different types of buildings, including:

  • New dwellings (houses, flats, etc.)
  • Rooms for residential purposes (such as hotels, hostels, etc.)
  • Schools and other educational buildings
  • Commercial or mixed-use buildings where noise control is a concern


While the document itself offers guidance on how to meet the legal requirements, Part E of the regulations must be adhered to by law. Compliance is necessary during the construction of new buildings or major renovations to existing ones. If a project does not meet these standards, it could result in penalties, additional costs, or delays to the project’s approval or completion. Local authorities or building inspectors typically enforce these requirements during the building control process.
