What to check
Use these prompts with the responsible project team. Ticking a box does not certify compliance.
You can tick these prompts while reviewing the project.
Keep these records
- Requirement-to-evidence matrix showing who demonstrates each applicable requirement.
- Approved information, controlled revisions and inspection photographs.
- Commissioning, testing, completion and required building-user information.
Common mistakes
- Using a Welsh Approved Document for an England project because both originate from the 2010 instrument.
- Assuming a successful inspection transfers the designer's or contractor's compliance responsibilities.
When to get specialist help
Ask a competent designer and the appropriate building-control body when scope, compliance strategy or the applicable transitional requirements are unclear.
Scope and edition
Sources reviewed 17 October 2026. This is the amended framework, not a frozen 2010 code. England and Wales have diverged; check geography, commencement, transitional protection and subsequent amendments for the project.
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
Independent, plain-English reference notes by Saeed Azarshab. 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.
