Building Regulations Part H is the section of the Building Regulations 2010 covering drainage and waste disposal in England and Wales. The Approved Document H sets out the minimum requirements for foul water drainage, wastewater treatment, rainwater drainage, building over sewers, separate systems and solid waste storage. The regulations apply to new builds, extensions, material alterations and changes of use across Greater London and the wider UK. Compliance is enforced by Local Authority Building Control or Approved Inspectors, who review designs at submission and inspect work at key stages including testing. Practical implications for homeowners include the need for properly trapped fittings, adequate pipe gradients, accessible inspection chambers and approved soakaway design. The full formal reference document is the Building Regulations 2010 (as amended) and the accompanying Approved Document H.
