Covering Cambridge and nearby
We do not keep premises in Cambridge. Instead, enquiries about sensor upgrades and replacement come to us, we agree the price in writing, and a specialist engineer working under our management travels to the address in the CB1, CB2, CB3, CB4 and CB5 postcode districts on a date that suits the site.
Schools and colleges in and around Cambridge often want work done in the holidays, when entrances can be taken out of use without disrupting pupils. Planning ahead for half-term or summer dates makes it easier to find a slot that suits the timetable.
Nearby towns we also list for sensor upgrades and replacement (straight-line distance): Newmarket (12.6 miles), Ely (15.1 miles), Huntingdon (15.7 miles), Haverhill (15.9 miles), St Neots (16.3 miles), Letchworth (21.1 miles).
What to think about for sensor upgrades and replacement in Cambridge
- After a near miss at a door in Cambridge, keep a note of what happened and where the person was standing. It helps the engineer judge which zone the sensor failed to cover.
- 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.
- Rain, snow and blowing leaves can trigger radar sensors over exposed doors. Some sensors filter weather better than others, which the engineer weighs up when choosing a replacement.
- 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.
- 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.
Sensor upgrades and replacement in Cambridge: 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.
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.
How it works
- Share the details. Send the address in Cambridge, 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.
Send a photo of the door and sensor at your building in Cambridge, and we will confirm the visit price and the likely sensor before booking an engineer.
Sensor upgrades and replacement in Cambridge: questions
Will new sensors stop false openings at our entrance in Cambridge?
Usually. Modern sensors can ignore cross traffic and detect only people moving towards the door, and the zone can be narrowed. If the entrance faces a busy street or catches heavy weather, the engineer may suggest a sensor that filters those conditions better.
What do you charge for sensor upgrades and replacement in Cambridge?
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 Cambridge, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Our door in Cambridge 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.
Can you upgrade sensors on an old door in Cambridge?
Most older doors can take modern sensors. A few very old controllers cannot monitor current safety sensors. If yours is one of them, we explain whether a controller upgrade or a new drive unit is the better option, and quote it, before any work is done.
What should I tell you when reporting a fault in Cambridge?
The address, the type of door, what it is doing or not doing, when the problem started and whether it is safe to use. A photo of the operator label showing the make, and a short video of the fault, help a great deal. With that, we can agree the visit price in writing and send an engineer with the right parts where possible.
Can you price a repair in Cambridge from photos?
Sometimes. Clear photos of the door, the operator cover and any label showing the make and model, plus a description of what the door is doing, can let us price a likely repair before a visit. Where the cause is not obvious, we agree a diagnostic visit price in writing first and quote the repair afterwards.
Which building regulations apply to a new automatic entrance in Cambridge?
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.
