Fire door hold-open devices for Barnet buildings
From the EN5 postcode district outwards, we take on fire door hold-open devices across Barnet for homes, blocks and workplaces.
Around Barnet, clinics, purpose-built blocks of flats and shared houses all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
Where doors in Barnet care homes, schools or offices are being wedged open, a hold-open device is the safe fix. We coordinate with your fire alarm contractor in Barnet so every hold-open releases when it should.
Working with your alarm contractor
Hard-wired hold-opens need an interface with the fire alarm, which is usually designed and certified by your fire alarm contractor. We fit and commission the door side and coordinate the interface, then test that every device releases when the alarm operates.
What you get:
- Coordination of alarm interface
- Hold-open and free-swing closers
- Electromagnetic holders to BS EN 1155
- Assessment of door use and alarm system
The regulations behind fire doors in Barnet
The rules that apply to fire doors in Barnet are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts. In London, the London Fire Brigade is the enforcing authority for fire safety law.
Where a Barnet block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Is it legal to wedge open a fire door?
