Building Regulations topic map

A conversation aid for homeowners: the official subject headings to raise with a competent designer, builder and certifier, not a design specification or compliance checklist.

Important: the Building Regulations contain functional requirements. Official Technical Guidance Documents describe recognised approaches, but project-specific design and compliance decisions belong with competent professionals.

Structure and site

Part A addresses structure. Part C covers site preparation and resistance to moisture; Part D addresses materials and workmanship. Record which drawings, calculations, specifications and product information address these topics.

Fire and movement

Part B covers fire safety. Part K addresses stairways, ladders, ramps and guards. Keep the design-team explanation with the relevant drawing revision instead of reducing these topics to a supplier brochure statement.

Indoor environment

Part E addresses sound, Part F ventilation and Part G hygiene. Ask how the specified systems work together, who is responsible for commissioning where applicable, and which records will be handed over.

Water and heat

Part H covers drainage and waste-water disposal. Part J addresses heat-producing appliances. File service layouts, appliance information and later changes with the project’s controlled design set.

Energy

Part L addresses conservation of fuel and energy. Keep the applicable edition and project assessment records with the design file. A marketing energy label or general product claim is not a project compliance record.

Access and use

Part M addresses access and use. Ask the project designer how the applicable requirements are reflected in drawings and specifications, and keep the issued answer with the project file.

Turn the map into a document index

For each topic judged relevant by the project team, record the responsible person, current document reference, revision date and any inspection or completion record expected. Leave an item open when evidence is missing; this private index helps organise the file but does not itself demonstrate compliance.
