Covering Chiswick and nearby
We cover the whole of the W4 postcode district, along with nearby towns in Greater London. You book each visit for drive unit replacement directly with us, and a specialist automatic door engineer working under our management travels to your site on the agreed date.
Security matters on busy London streets, so entrances in Chiswick often need doors that lock firmly at night and work with alarms, shutters or access control. The operator, the locking and any shutter are planned together so they work in the right order.
Nearby towns we also list for drive unit replacement (straight-line distance): Hammersmith (1.3 miles), Acton (1.4 miles), Shepherd's Bush (1.8 miles), Ealing (2.3 miles), Fulham (2.7 miles), Putney (2.8 miles).
What to think about for drive unit replacement in Chiswick
- Business parks and office blocks in Chiswick with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Listed buildings and conservation areas in Chiswick make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Busy retail entrances in Chiswick may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- 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.

Standards and rules in England
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.
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.
How it works
- Get in touch. Call, email or use the form with the address and what you have in mind. If you are not sure which type of door suits, describe the entrance and we will suggest the options worth considering.
- Survey and advice. The survey costs nothing and carries no obligation. The engineer checks the site and explains which options suit the entrance, the people using it and the budget, before anything is priced.
- Quote in writing. You receive a fixed, itemised quote for drive unit replacement in Chiswick, covering equipment, installation, testing and handover, with the lead time and payment stages set out clearly.
- Install, test, explain. The engineer installs and commissions the door, tests the sensors, safety functions and emergency behaviour, and walks you through the controls. The handover pack records what was installed and tested.
If parts for your door in Chiswick 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 Chiswick: questions
What lead time should we expect in Chiswick?
Once the quote is accepted, drive units are typically 2 to 4 weeks to arrive, depending on the length and weight rating needed. The changeover date is agreed with you as soon as the parts are confirmed, and it can be planned around your opening hours.
What price range should I expect for drive unit replacement in Chiswick?
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 Chiswick 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 Chiswick 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 Chiswick?
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.
How are payments structured for work in Chiswick?
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.
Can automatic doors be fitted to a listed building in Chiswick?
Often, yes, but listed building consent is normally needed for changes that affect the character of the building, inside or out. Slim operators, concealed fixings and automating the existing door can all reduce the visual impact. Speak to the conservation officer at the local planning authority early; we can provide drawings and specifications to help.
Do businesses in Chiswick 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.
