Key checks for Hitchin projects
Glazed area limits
Each door design allows a maximum glazed area and aperture positions. Bigger glass needs a door tested for it.
Accessibility
Opening forces, vision panel zones and contrast need to work with accessibility guidance as well as fire.
Ongoing checks
Residential blocks in England over 11 metres need regular fire door checks under the Fire Safety (England) Regulations 2022; glazed doors are included.
Fire glazing rules in England
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.

Yes, some steel, aluminium and timber doorsets are tested with large or full-height glazing. The glass must be the type and size in the evidence.

Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
