Approved Document H: Drainage and waste disposal

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

Part H concerns drainage and waste disposal, including foul drainage and relevant rainwater and waste arrangements. Good access for inspection and maintenance is part of a useful design. Building-regulations review does not remove the need to establish separate sewer connection, build-over or other consents where applicable.

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

When to use this guide

  • Planning an extension, new drainage connection or drainage alteration
  • Coordinating underground drainage before foundations and floor work
  • Arranging access for inspection, testing and future maintenance

Keep these records

  • Survey, drainage design and relevant consent correspondence
  • Inspection and test records
  • As-installed drainage and access information

Common mistakes

  • Assuming building-control approval grants every sewer-related consent.
  • Covering underground work before agreed checks and records have been completed.

When to get specialist help

Use competent drainage and structural input where existing sewers, uncertain routes or nearby foundations affect the proposal.

About this library

The library covers the 42 subjects listed here; it is not every law affecting construction, an official government publication or a project-specific compliance decision. Building Regulations, Approved Documents, workplace safety duties and planning permissions have different roles.

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.
