Covering Northfleet and nearby
Addresses anywhere in the DA10 and DA11 postcode districts can book sensor upgrades and replacement through us. The engineer who attends works under our management and travels to the site. There is no branch in Northfleet, so the price, the booking and the paperwork all come from one place.
Many buildings in Northfleet 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 sensor upgrades and replacement (straight-line distance): Gravesend (2.0 miles), Grays (2.0 miles), South Ockendon (4.6 miles), Dartford (4.8 miles), Erith (7.0 miles), Stanford-le-Hope (7.1 miles).
What to think about for sensor upgrades and replacement in Northfleet
- 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 Northfleet, keep a note of what happened and where the person was standing. It helps the engineer judge which zone the sensor failed to cover.
- Shopping parades and older shopfronts in Northfleet sometimes have low transoms or canopies that limit where a sensor can be mounted. The engineer checks height and angle first.
- 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.
Sensor upgrades and replacement in Northfleet: 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 Northfleet, 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 Northfleet, and we will confirm the visit price and the likely sensor before booking an engineer.
Sensor upgrades and replacement in Northfleet: questions
Can you price new sensors for my door in Northfleet 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.
Is there a guide price for sensor upgrades and replacement in Northfleet?
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 Northfleet, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Can you upgrade sensors on an old door in Northfleet?
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.
Our door in Northfleet 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 offer service contracts in Northfleet?
Yes. A service contract sets out how many visits a year each door receives, what each visit includes and the price, all agreed in writing before you sign. Contracts suit sites with several doors or busy entrances, because visits are planned ahead and the records stay in one place. Contract length and notice terms are shown in the agreement.
Do you leave a written record after each visit in Northfleet?
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.
Which building regulations apply to a new automatic entrance in Northfleet?
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.
