Fire door hold-open devices: our service in Hertfordshire
Our fire door hold-open devices service runs throughout Hertfordshire. Main towns include Watford, Hemel Hempstead and Stevenage, and we cover the smaller places in between.
We coordinate with your fire alarm contractor in Hertfordshire so every hold-open releases when it should. Free-swing closers suit Hertfordshire settings where residents or pupils find doors hard to open.
Managing agents, landlords, schools, care providers, businesses and homeowners in Hertfordshire can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
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 Hertfordshire
In Hertfordshire, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Hertfordshire building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Common questions
Do you provide fire door hold-open devices across Hertfordshire?
Yes. We cover all of Hertfordshire, including Watford and Hemel Hempstead. Surveys and written quotes are free.
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.
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.
