Covering Harpenden and nearby
Sites across the AL5 postcode district are visited by specialist automatic door engineers working under our management. They travel to Harpenden for automatic sliding doors as bookings come in, so dates depend on the diary rather than a fixed local team, and we give you the earliest date we can offer when you book.
Independent businesses in Harpenden often have one entrance and cannot close for long. Work is usually scheduled early, late or on a quiet day, and where a door must be out of use for a period, we plan to keep the entrance usable or secure.
Nearby towns we also list for automatic sliding doors (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 automatic sliding doors in Harpenden
- Power is needed near the head of the door, usually from a fused spur. If there is no supply nearby, allow for an electrician to run one before the fitting day so the door can be commissioned straight away.
- Wind blowing straight at an entrance can make sliding leaves drag or cause the door to open when nobody is there. On exposed frontages across Hertfordshire, a partial opening mode or a draught lobby is worth considering.
- Entrances in Harpenden that sit on an escape route need the fire strategy checked before the door is designed, because that decides whether break-out leaves, alarm-linked opening or battery opening are required.
- Shops that use a roller shutter at night need the new header to sit below the shutter box and clear of its guide channels. Both are measured at survey so the door and shutter can work together.
- Schools, libraries and council buildings often prefer installation during holidays or at weekends. That is usually possible, as long as the dates are known when the order is placed and the door can be made in time.

Standards and rules in England
In Great Britain a new or converted powered door must meet the Supply of Machinery (Safety) Regulations 2008 before it is first used, and can carry the UKCA or the CE marking. 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.
Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, which can include altering a physical feature such as a heavy entrance door. New entrances and some alterations count as building work, so check with building control before the work is ordered.
How it works
- Describe what you need. Whether the job is automatic sliding doors for a busy entrance or for a single internal door, a brief description and some photos let us understand it and plan a survey visit in Harpenden.
- Free visit to the site. An engineer working under our management assesses the opening, the existing door and frame, the floor and the electrical supply, and notes any access, consent or timing issues to plan around.
- Your fixed quotation. The quote is fixed for the work it describes and lists each item, including any removal, making good and electrical work. It also states the lead time, the payment stages and the warranty terms.
- Fitting and sign-off. Work goes ahead on dates agreed with you. Once fitted, the door is adjusted and its safety functions are tested and recorded with reference to BS EN 16005, and you are shown how to use it.
Send us a photo of the doorway and its postcode, and we will arrange a free site survey in Harpenden and a fixed, itemised quote for a new sliding entrance.
Automatic sliding doors in Harpenden: questions
Do we need consent for a new entrance in Harpenden?
It depends on the building. A change to how a shopfront looks may need planning permission, and listed buildings may need listed building consent. Your local planning authority decides. We flag the question at survey and can provide drawings and product details to support an application if one is needed.
Is there a guide price for automatic sliding doors in Harpenden?
Our guide is £4,495 to £12,995 excluding VAT (per door set), the same guide prices 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 the old door in Harpenden be removed and taken away?
Yes. Removal of the existing door and frame is listed as a line in the quote, along with making good around the opening. Glass and aluminium are taken away for recycling where possible. If the old door belongs to a landlord, tell us at survey so its removal can be agreed with them before the work is booked.
Who checks that a new sliding door in Harpenden is safe?
The installing engineer sets the speeds, forces and sensor zones, tests the door and completes a site-specific risk assessment before handing it over. You keep the test record and the risk assessment for your own files, and they form the baseline for every service visit and inspection after that.
What do you need from us for parking and access in Harpenden?
Somewhere for the engineer's van as close to the entrance as possible, and a clear working area around the door. If parking is restricted, loading rules apply or the site has security procedures, tell us when you book. Those details go into the plan so the visit is not held up on the day.
How much disruption should we expect while the work is done in Harpenden?
Most installations take one visit or a short series of visits, with dust and noise kept to the area around the door. The engineer screens off the work area, keeps a route in or out where possible and clears up before leaving. Larger entrances, lobbies or structural changes take longer, and the quote explains how that work is phased.
Who is responsible for automatic doors on escape routes in Harpenden?
Under the Regulatory Reform (Fire Safety) Order 2005 the responsible person for the premises must make sure escape routes work and fire safety equipment is maintained. Automatic doors on an escape route need fail-safe opening or break-out, set by the fire strategy.
