Covering Harpenden and nearby
Engineers working under our management travel to addresses across the AL5 postcode district for sensor upgrades and replacement. There is no depot or showroom in Harpenden; you arrange everything with us by phone, email or the form on this page, and we confirm the price in writing first.
Libraries, health centres and council buildings in Harpenden still need accessible entrances, whatever their size. A single automatic door with a push pad or touch-free switch is often enough to give everyone easy access.
Nearby towns we also list for sensor upgrades and replacement (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 sensor upgrades and replacement in Harpenden
- Sensor changes on escape route doors must never stop the door opening when it needs to. The engineer checks the door's escape mode after any sensor work.
- Swing doors in narrow corridors need sensors on the leaf to protect people on both sides. The engineer checks the swing path and any walls or fittings close by.
- After a near miss at a door in Harpenden, keep a note of what happened and where the person was standing. It helps the engineer judge which zone the sensor failed to cover.
- Sites in Harpenden that open early or close late may want sensor work done outside trading hours. Tell us the quieter times when you book the visit.
- If several doors at one site have the same old sensor, replacing them together keeps the doors behaving consistently and may reduce the cost per sensor.
Sensor upgrades and replacement in Harpenden: guide prices
The visit price is agreed in writing before an engineer attends; parts and any further work are quoted before they are done. Guide price: typically £195 to £495 ex VAT.
| Item | Guide price | Notes |
|---|---|---|
| Add or replace a safety or activation sensor | £195 – £495 | per sensor fitted, ex VAT |
| Touch-free switch or push pad | £145 – £395 | per switch, ex VAT |
| Side-screen or light-curtain protection | from £295 | per door, ex VAT; on survey |
Sensor prices cover the part, fitting and set-up. If a sensor is fitted on a visit of its own, the visit charge (from £95 ex VAT) is added, and we confirm the total in writing before an engineer attends. Each sensor is set up for the door and tested before the engineer leaves.
Standards and rules in England
BS EN 16005 is the current standard for the safety in use of powered pedestrian doors, and BS 7036-0:2014 is the British code of practice for risk assessment and risk reduction used alongside it. Standards are not law in themselves, but they are the recognised benchmark for showing an automatic door is safe to use, and we set up, test and document doors with reference to them. Standards are not retrospective, so an older door does not become unlawful when a standard is updated; a site-specific risk assessment shows whether any upgrades are sensible.
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. HSE guidance on those regulations says the frequency of maintenance depends on the equipment and the manufacturer’s information.
How it works
- Share the details. Send the address in Harpenden, the door type and make if you know it, and a description or video of the problem. For servicing, tell us how many doors there are and how busy each one is.
- Price confirmed in writing. We agree the visit price in writing before an engineer attends. Some straightforward repairs can be priced in full from photos and the make and model of the door.
- Diagnosis and repair. A specialist engineer attends on the agreed date, finds the cause, repairs or services the door, and tests its operation, sensors and safety functions with reference to BS EN 16005.
- Written record. Each visit ends with a written record for your files. Anything still outstanding, such as parts on order or recommended upgrades, is quoted before any further work is done.

Sensor upgrades and replacement in Harpenden: questions
Can a risk assessment in Harpenden tell us which sensors we need?
Yes. A safety inspection tests each hazard zone and records where sensor coverage is missing or poor. The report then lists the sensors or light curtains needed, and we can quote those items exactly as listed, or you can pass the report to another competent installer.
What will sensor upgrades and replacement in Harpenden cost?
Our guide is £195 to £495 excluding VAT (per sensor fitted), the same guide prices we use across the UK. We agree the visit price in writing before an engineer attends in Harpenden, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Our door in Harpenden closes on people. Is that a sensor fault?
It is likely, and the door should be treated as unsafe. Switch it to a safe mode, such as manual or open, and keep people away from the leaves. Tell us it is unsafe and we will give you the earliest visit we can offer, then the engineer will check the safety sensors and their zones.
Will you record the sensor settings for our building in Harpenden?
Yes. The job report lists each sensor fitted, its position, the settings used and the test results. Keep it with your service records, as it helps future engineers and shows the door's safety set-up was checked after the work. The same details are useful if an insurer or inspector asks.
Do you leave a written record after each visit in Harpenden?
Yes. Every visit ends with a written record of what was checked, what was done and anything that still needs attention. For safety inspections you receive a report of the findings and a site-specific risk assessment. Keeping these on file is the usual way to show that a workplace door is maintained and in good working order.
How often should automatic doors in Harpenden be serviced?
No law sets a fixed interval. We recommend a trained engineer checks the safety functions at least once a year, with service intervals set by the manufacturer's instructions and how heavily the door is used; busy doors are often serviced more often. Site staff should also carry out simple regular checks and keep a record of them.
Do businesses in Harpenden have to fit automatic doors?
No law says every building must have automatic doors. Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, and building regulations guidance in England calls for a powered door where an entrance door would otherwise be too heavy to open. An automatic door is often the simplest way to meet both.
