Covering Harpenden and nearby
We cover the whole of the AL5 postcode district, along with nearby towns in Hertfordshire. You book each visit for automating an existing door directly with us, and a specialist automatic door engineer working under our management travels to your site on the agreed date.
Many buildings in Harpenden are older, with timber frames, thick walls, steps or uneven thresholds. These affect where an operator and sensors can go, and the engineer checks them on site before anything is fitted or adjusted.
Nearby towns we also list for automating an existing door (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 automating an existing door in Harpenden
- Check how the door hangs now. A door that drops, rubs on the floor or needs a shoulder to close will need its hinges or frame sorted before an operator goes on.
- If the door is on an escape route, keep the existing panic or emergency hardware working. The operator should not stop the door opening by hand in an emergency.
- Listed buildings and conservation areas in Harpenden may need consent for an operator on an original door. Mounting it on the inside face usually keeps the street view the same.
- Shop fronts on high streets in Harpenden often have narrow aluminium frames. The survey checks the transom can carry the operator without flexing, and whether it needs reinforcing.
- Think about how the door is locked. If it is locked by key every night, an electric lock or keep may be worth adding so the door can be secured without switching the operator off.

Standards and rules in England
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. Fitting an automatic door helps, but does not on its own guarantee those duties are met.
Whoever motorises a manual door, or builds an automatic door from separate parts, may take on the manufacturer’s legal duties for the finished door: a risk assessment, a technical file kept available for the authorities, a Declaration of Conformity, the conformity marking and instructions. You receive the Declaration of Conformity and the instructions at handover. 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.
How it works
- Describe what you need. Whether the job is automating an existing door 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.
Tell us about the door, how it is used and who uses it, and we will plan a retrofit for your building in Harpenden.
Automating an existing door in Harpenden: questions
Can you automate a fire door at our premises in Harpenden?
Usually, using an operator designed for fire doors and wired to the fire alarm so the door closes when the alarm operates. We check the door's rating and condition first. A fire door that does not close and seal properly needs repairing before an operator goes on.
What do you charge for automating an existing door in Harpenden?
Our guide starts from £1,795 excluding VAT (per door), the same guide price we use across the UK. For homes that is from £2,154 including VAT. 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 automate a front door at a house in Harpenden?
Yes. Front doors at home are often automated for wheelchair users and people with limited grip, usually with an electric keep or lock so the door locks itself as it closes. Home prices are quoted including VAT, and the survey is free.
Will automating our door in Harpenden need planning permission?
Fitting an operator to an existing door does not usually need planning permission, but a listed building may need consent for fixings or new switches on the outside. In a conservation area, mounting the operator inside often avoids any change to the street view. Check with the planning authority if in doubt.
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.
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.
