What to think about for sensor upgrades and replacement in Sunbury-on-Thames
- 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.
- Shopping parades and older shopfronts in Sunbury-on-Thames sometimes have low transoms or canopies that limit where a sensor can be mounted. The engineer checks height and angle first.
- Corridor doors that people walk past rather than through may work better on a touch-free switch than a motion sensor, cutting needless openings and heat loss.
- After a near miss at a door in Sunbury-on-Thames, keep a note of what happened and where the person was standing. It helps the engineer judge which zone the sensor failed to cover.
- 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 upgrades and replacement in Sunbury-on-Thames: 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
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.
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
- 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.

Sensor upgrades and replacement in Sunbury-on-Thames: questions
Can you price new sensors for my door in Sunbury-on-Thames from photos?
Often, yes. Photos of the sensor, the door from both sides and the label on the operator cover usually tell us which sensor is needed and whether it suits the controller. We can then quote the sensor and fitting in advance, with the visit price confirmed before anyone travels.
How much should I budget for sensor upgrades and replacement in Sunbury-on-Thames?
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 Sunbury-on-Thames, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Will you record the sensor settings for our building in Sunbury-on-Thames?
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.
Can you upgrade sensors on an old door in Sunbury-on-Thames?
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.
How is the visit price set for work in Sunbury-on-Thames?
We agree the visit price with you in writing before an engineer attends. It is based on the type of door, the work requested and the location. If parts or further work are needed once the engineer has found the cause, those are quoted before they are done, so the cost never moves without your agreement.
Can you price a repair in Sunbury-on-Thames 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.
Do businesses in Sunbury-on-Thames 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.
