Covering Harpenden and nearby
We cover the whole of the AL5 postcode district, along with nearby towns in Hertfordshire. You book each visit for fire door hold-open devices directly with us, and a specialist automatic door engineer working under our management travels to your site on the agreed date.
Doors at quieter sites in Harpenden and elsewhere in Hertfordshire can go many years between checks. A safety inspection looks at how the sensors, closing behaviour and emergency functions are working, and gives you a written record to keep on file.
Nearby towns we also list for fire door hold-open devices (straight-line distance): St Albans (4.7 miles), Luton (5.0 miles), Hemel Hempstead (5.9 miles), Welwyn Garden City (6.5 miles), Hatfield (6.8 miles), Dunstable (8.5 miles).
What to think about for fire door hold-open devices in Harpenden
- Fire doors on stairs and protected escape routes need particular care. The fire risk assessment may allow some of them to be held open and not others, so pricing is door by door.
- Busy office corridors suit wall magnets that hold doors right back against the wall, out of the way of people and trolleys, until the alarm releases them.
- Hard-wired magnets need a power supply near each door. In buildings in Harpenden where that is awkward, battery units avoid running new cables along finished corridors.
- Think about who tests the fire alarm each week at your building in Harpenden. Adding a walk past the held-open doors to that test is the easiest way to confirm they release.
- Doors that open too far from a wall for a wall magnet can use a floor-mounted unit or a magnet on an extension arm. The survey measures where each door rests when open.

Standards and rules in England
Workplace law (the Workplace (Health, Safety and Welfare) Regulations 1992) expects powered doors to have suitable and effective features to stop them trapping anyone and, where needed for safety, to open by hand unless they open automatically if the power fails. Doors at work must also be kept in efficient working order under a suitable system of maintenance.
Fire doors that are held open must close automatically when the fire alarm operates. Where hold-open devices can be used is decided by the fire risk assessment, which is the job of the responsible person under the Regulatory Reform (Fire Safety) Order 2005.
How it works
- Get in touch. Call, email or use the form with the address and what you have in mind. If you are not sure which type of door suits, describe the entrance and we will suggest the options worth considering.
- Survey and advice. The survey costs nothing and carries no obligation. The engineer checks the site and explains which options suit the entrance, the people using it and the budget, before anything is priced.
- Quote in writing. You receive a fixed, itemised quote for fire door hold-open devices in Harpenden, covering equipment, installation, testing and handover, with the lead time and payment stages set out clearly.
- Install, test, explain. The engineer installs and commissions the door, tests the sensors, safety functions and emergency behaviour, and walks you through the controls. The handover pack records what was installed and tested.
Send us a list of the doors you want held open at your building in Harpenden, plus any notes from your fire risk assessment, and we will arrange a survey at no cost.
Fire door hold-open devices in Harpenden: questions
How soon can hold-open devices be fitted in Harpenden?
Once the quote is accepted, supply is typically 1 to 3 weeks, and fitting a few devices on one floor usually takes a day. Larger jobs are planned in stages so doors are never left without protection. Your quote shows the expected programme, and fitting dates are agreed with you before work starts.
What will fire door hold-open devices in Harpenden cost?
Our guide starts from £145 excluding VAT (per door), the same guide price we use across the UK. The free site survey in Harpenden confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Can you work with the fire alarm company that maintains our system in Harpenden?
Yes, and for wired devices we usually need to. The connection at the alarm panel is made by, or agreed with, the engineer who looks after your alarm. We share the device details with them and agree the visits, so the alarm and the doors can be tested together once the work is finished.
Do care homes in Harpenden use free-swing closers?
Many do. A free-swing closer lets residents open their bedroom door without pushing against a closer, and it still shuts the door when the fire alarm operates. Whether it suits each room depends on the home's fire risk assessment and evacuation strategy, which we read before recommending any device.
Can installation in Harpenden happen outside opening hours?
Yes. Many shops, surgeries and offices prefer work early in the morning, in the evening or at weekends, when the entrance is quietest. Tell us your constraints when you enquire and they are built into the plan. Any extra cost for out-of-hours work is shown in the written quote rather than added afterwards.
Will the building stay secure while the entrance is being changed?
We plan to keep the entrance usable or secure throughout. Where a door has to come out, the work is sequenced so the opening is closed up before the engineer leaves, or a temporary door or hoarding is arranged when a longer gap cannot be avoided. How this is handled for your site in Harpenden is agreed before work starts.
Which building regulations apply to a new automatic entrance in Harpenden?
In England the guidance is Approved Document M (Volume 2) for access, Approved Document B for fire safety and escape routes, and Approved Document K for glazing and powered doors. A new entrance can count as building work, so building control should be involved before it is ordered.
