Regulations for design and construction: Knowledge hub

Key takeaways

Regulations are mandatory rules and statutory instruments that govern how buildings are designed, constructed, and occupied—unlike voluntary policies, they carry legal force. Compliance ensures health, safety, accessibility, energy efficiency, and structural performance, while preventing enforcement action, fines, or delays.

This knowledge hub relates specifically to the building regulations. For other regulations see:

The buildings regulations and why they matter

The building regulations set minimum standards for all aspects from structural integrity to fire safety and energy efficiency. They set out:

• What qualifies as ‘building work’ and so falls under the control of the regulations.
• What types of buildings are exempt (such as temporary buildings).
• The notification procedures that must be followed when starting, carrying out, and completing building work.
• Requirements for specific aspects of building design and construction.

A series of approved documents provide general guidance about how specific aspects of building design and construction can comply with the Building Regulations.
