Covering Sidcup and nearby
Homes, businesses and public buildings throughout the DA14 and DA15 postcode districts can arrange drive unit replacement with us. We are the contracting party and organise every visit; the engineer, who works under our management, travels in to Sidcup for the job rather than working from premises in town.
Many London entrances can only be worked on outside trading hours. For sites in Sidcup, early starts, evenings and weekends can be arranged, with any extra cost set out in the written price before the job is confirmed.
Nearby towns we also list for drive unit replacement (straight-line distance): Welling (2.5 miles), Eltham (2.8 miles), Bexleyheath (3.0 miles), Orpington (3.6 miles), Swanley (3.6 miles), Bromley (4.1 miles).
What to think about for drive unit replacement in Sidcup
- Doors linked to the fire alarm or access control in Sidcup need those links rewired to the new controller. Let us know which systems connect to the door.
- Check the power supply. A dedicated fused spur and isolator near the door is usually needed, and older installations sometimes need electrical work before the new operator goes in.
- Older shopfronts in Sidcup may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- If the door is on an escape route, the new drive unit must be set up to open, break out or be openable by hand, as the building's fire strategy requires.
- Battery backup is easier to add with a new drive unit. It lets the door open or close safely in a power cut, which matters most on escape routes.

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.
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. 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.
How it works
- Describe what you need. Whether the job is drive unit replacement for a busy entrance or for a single internal door, a brief description and some photos let us understand it and plan a survey visit in Sidcup.
- Free visit to the site. An engineer working under our management assesses the opening, the existing door and frame, the floor and the electrical supply, and notes any access, consent or timing issues to plan around.
- Your fixed quotation. The quote is fixed for the work it describes and lists each item, including any removal, making good and electrical work. It also states the lead time, the payment stages and the warranty terms.
- Fitting and sign-off. Work goes ahead on dates agreed with you. Once fitted, the door is adjusted and its safety functions are tested and recorded with reference to BS EN 16005, and you are shown how to use it.
If parts for your door in Sidcup are obsolete, talk to us before replacing the entrance. A free survey shows what can be kept and what it will cost.
Drive unit replacement in Sidcup: questions
Can the replacement in Sidcup include a service plan?
It can. After the changeover we recommend a service interval based on how heavily the door is used, and a service contract can be set up with a written record of each visit. Servicing is priced separately and agreed in writing before any visit takes place.
What will drive unit replacement in Sidcup cost?
Our guide is £1,995 to £3,995 excluding VAT (per door), the same guide prices we use across the UK. The free site survey in Sidcup confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you provide paperwork for the converted door in Sidcup?
Yes. When we fit a new drive unit we prepare the paperwork for the finished door, including the risk assessment, Declaration of Conformity and user instructions, and hand it over with the test results and settings. It belongs with your building records.
How long will our entrance in Sidcup be closed for the changeover?
A standard sliding door changeover typically takes a day, and a swing operator often less. The work can be scheduled early, after closing or at a weekend so it causes less disruption. Your quote shows the planned date and how long the entrance will be out of use.
Can installation in Sidcup happen outside opening hours?
Yes. Many shops, surgeries and offices prefer work early in the morning, in the evening or at weekends, when the entrance is quietest. Tell us your constraints when you enquire and they are built into the plan. Any extra cost for out-of-hours work is shown in the written quote rather than added afterwards.
What do you need from us for parking and access in Sidcup?
Somewhere for the engineer's van as close to the entrance as possible, and a clear working area around the door. If parking is restricted, loading rules apply or the site has security procedures, tell us when you book. Those details go into the plan so the visit is not held up on the day.
Which building regulations apply to a new automatic entrance in Sidcup?
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.
