Covering Greenwich and nearby
We do not keep premises in Greenwich. Instead, enquiries about drive unit replacement come to us, we agree the price in writing, and a specialist engineer working under our management travels to the address in the SE10 postcode district on a date that suits the site.
Transport hubs, large stations and busy retail streets in and around Greenwich put automatic doors under near-constant use. Heavy-duty operators, break-out leaves on escape routes and regular servicing are typical requirements at entrances this busy.
Nearby towns we also list for drive unit replacement (straight-line distance): Lewisham (0.9 miles), Canary Wharf (1.9 miles), Catford (2.3 miles), Peckham (2.5 miles), Canning Town (2.8 miles), Eltham (3.3 miles).
What to think about for drive unit replacement in Greenwich
- Business parks and office blocks in Greenwich with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Worn floor guides and rollers can shorten the life of a new operator. It is often worth replacing them during the same visit rather than coming back later.
- 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.
- Busy retail entrances in Greenwich may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- 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.
Whoever motorises a manual door, or builds an automatic door from separate parts, may take on the manufacturer’s legal duties for the finished door: a risk assessment, a technical file kept available for the authorities, a Declaration of Conformity, the conformity marking and instructions. You receive the Declaration of Conformity and the instructions at handover. In Great Britain a new or converted powered door must meet the Supply of Machinery (Safety) Regulations 2008 before it is first used, and can carry the UKCA or the CE marking.
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 Greenwich.
- 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 Greenwich 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 Greenwich: questions
Can you fit a new operator to a door another company installed in Greenwich?
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.
How much should I budget for drive unit replacement in Greenwich?
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 Greenwich confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
How long will our entrance in Greenwich 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.
Do you replace automatic door drive units in Greenwich?
Yes. We are the contracting party for drive unit replacements in Greenwich, and the survey and changeover are carried out by specialist engineers we manage. The survey is free and checks that the frame and leaves are worth keeping. You then receive a fixed, itemised quote for the new operator, sensors and any other parts the door needs.
What does the free site survey in Greenwich involve?
An engineer working under our management visits the building, measures the opening, checks the frame, floor, head height and power supply, and looks at how people use the entrance. The survey is free and carries no obligation. Afterwards you receive a fixed, itemised written quote for drive unit replacement, with drawings where the door type needs them.
How are payments structured for work in Greenwich?
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 Greenwich 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.
