In the UK, installing steel doors must comply with specific building regulations to ensure safety, security, and energy efficiency:

Security Standards: For residential properties, steel doors should meet the requirements of Approved Document Q, which specifies standards for doors to resist physical attacks by opportunistic burglars. This includes the use of high-quality locks and reinforced frames.

Fire Safety: Depending on their location and purpose, steel doors may need to meet fire resistance standards as outlined in Approved Document B. This ensures they can withstand fire for a specified period, aiding in safe evacuation. (GOV.UK)

Thermal Performance: Steel doors must adhere to Approved Document L, which relates to the energy efficiency of a property. This includes ensuring the door is fitted correctly with no gaps, is of the correct thickness, and uses appropriate materials to limit heat loss. The thermal efficiency of a door needs to have a minimum U-value of 1.8W/(㎡K).

For comprehensive details, refer to the UK government’s Building Regulations Approved Documents.
