Coverage across Hertfordshire
For sensor upgrades and replacement anywhere in Hertfordshire, you deal with one contracting party and one written price. We organise the visit, brief the engineer, who works under our management, and keep the paperwork together afterwards. Below you will find the towns we list in this part of England, 19 in all; if your address sits outside them, the arrangements are exactly the same.

What to think about for sensor upgrades and replacement in Hertfordshire
- 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.
- Shiny, wet or newly polished floors can confuse infrared safety sensors. Mention any recent floor changes at your building in Hertfordshire so the zones can be set for the new surface.
- 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.
- Doors with side screens may need a light curtain on the leaf edge or post to protect the gap. This is one of the most common upgrades on older sliding doors.
- Care settings in Hertfordshire often need longer hold-open times and wider safety zones for residents who move slowly, use walking frames or pause in the doorway.
Sensor upgrades and replacement in Hertfordshire: 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
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.
No law sets a fixed service interval. We recommend that 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, and that someone on site carries out simple regular checks and keeps a record.
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.
How it works
- Make contact. Phone, email or use the form. Tell us the type of door, what it is doing and whether it is safe to use, so the right visit for sensor upgrades and replacement can be planned.
- Written visit price. The cost of attending is agreed in writing before the visit is booked. For a planned service or inspection, the price per door and what each visit includes are set out at the same time.
- On-site work. The engineer, working under our management, checks the door from end to end, deals with the fault or the service, and tests every safety function and sensor setting before signing the door off.
- Report and quote. You receive a report of the findings. Where a repair, part or upgrade is recommended, it is quoted in writing so you can decide, and the door is left in a safe state if it cannot be used.
Ask for a price on new safety or activation sensors in Hertfordshire. Each one is set up for the door's hazard zones and tested before the engineer leaves.
Sensor upgrades and replacement in Hertfordshire: questions
Can a risk assessment in Hertfordshire 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 price range should I expect for sensor upgrades and replacement in Hertfordshire?
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 Hertfordshire, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Our door in Hertfordshire 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.
Do you replace automatic door sensors in Hertfordshire?
Yes. Sensor replacement and upgrades in Hertfordshire are booked and managed by us and carried out by engineers who specialise in automatic doors. They work on sensors for sliding, swing, folding and revolving doors from most makers. The visit cost is set in writing before they attend, and each new sensor is tested before they leave.
How soon can an engineer get to Hertfordshire?
We do not promise response times. When you book, we give you the earliest date we can offer and confirm it once the price is agreed. If the door is unsafe in the meantime, it is usually best to switch it off or set it to a safe mode, put up a sign and keep people clear of it.
How often should automatic doors in Hertfordshire 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 Hertfordshire 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.
