We provide fire door hold-open devices across Greater London, covering 82 towns and 279 postcode districts, including London, Islington and City of Westminster.

Fire door work in Greater London spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.
Types of hold-open
Electromagnetic door holders are wall or floor magnets wired to the fire alarm. Hold-open closers combine the closer and the hold-open in one unit. Free-swing closers let the door move freely and close it on alarm. Some battery units listen for the alarm sound; these must be suitable for the alarm system and the building. The right choice depends on the door, the alarm and how people use the space.
Rules and responsibilities in Greater London
The rules that apply to fire doors in Greater London 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. Enforcement of fire safety law in Greater London sits with the London Fire Brigade.
Where a Greater London 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.

Questions
Do you provide fire door hold-open devices across Greater London?
Yes. We cover all of Greater London, including London and Islington. Surveys and written quotes are free.
Is it legal to wedge open a fire door?
Wedging a fire door open defeats its purpose and is likely to breach the duties under fire safety law. A hold-open device that releases on alarm is the safe alternative.
What is the difference between a hold-open and a free-swing closer?
A hold-open keeps the door at a fixed open position. A free-swing closer lets the door move freely, as if no closer were fitted, until the alarm sounds.
