Covering Westminster and nearby
Sites across the SW1A, SW1E, SW1H, SW1V, SW1Y and W2 postcode districts are visited by specialist automatic door engineers working under our management. They travel to Westminster for drive unit replacement as bookings come in, so dates depend on the diary rather than a fixed local team, and we give you the earliest date we can offer when you book.
Getting a van close to the door is often the hardest part of a London job. Red routes, controlled parking zones and loading rules vary from street to street, so access and parking restrictions are planned into the visit to Westminster before it is booked.
Nearby towns we also list for drive unit replacement (straight-line distance): Chelsea (1.6 miles), Battersea (1.8 miles), the City of London (2.2 miles), Kensington (2.4 miles), Clapham (2.4 miles), Brixton (2.5 miles).
What to think about for drive unit replacement in Westminster
- 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.
- Doors linked to the fire alarm or access control in Westminster 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.
- Listed buildings and conservation areas in Westminster make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Hospitals and care homes in Westminster may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.

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
- Send photos and the address. A few pictures of the door from both sides, the address in Westminster and a note of who uses the entrance help us understand the job before anyone visits the site.
- No-cost survey on site. We arrange a survey at a time that suits the building. The engineer records measurements, fixings and power, plus any constraints such as listed status, opening hours or access for deliveries.
- Itemised quote to approve. We price every element of the work on drive unit replacement separately in a written quote that you can check, share and approve. Lead time and payment stages are stated, and nothing is ordered until you accept.
- Fit, test and hand over. On the agreed dates the engineer installs the equipment, commissions the operator and tests each safety function. You get a demonstration, the test record and any conformity paperwork that applies to the work.
If parts for your door in Westminster 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 Westminster: questions
Can you fit a new operator to a door another company installed in Westminster?
Yes. We replace drive units on doors whoever fitted them. The survey identifies the existing header, leaves and track, and adapter plates usually let a new drive unit from one of the major European operator brands fit without changing the frame.
What will drive unit replacement in Westminster 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 Westminster confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
What if the frame of our door in Westminster is not worth keeping?
Then we will tell you. Damaged or corroded frames, glass that is not safety glass, or an opening that is too narrow for the people using it are all reasons to choose a new door instead. We can quote both options so you can compare them side by side.
Will you remove the old operator from our premises in Westminster?
Yes. The old drive unit, sensors and any other replaced parts are taken away as part of the job, and the work area is left clean. Disposal is included in the fixed quote, so there is nothing extra to arrange or pay for afterwards.
Do you service doors in Westminster after installing them?
Yes. 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. Servicing can follow on from the installation, with the price agreed in writing and a record left after every visit.
How are payments structured for work in Westminster?
Payment stages are set out in the quote before you accept it. Larger or made-to-order jobs may involve a deposit and a balance on completion, while smaller jobs may be invoiced once the work is finished. Nothing is charged for the survey itself, and the terms you accept are the terms that apply.
Do businesses in Westminster 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.
