Covering Hounslow and nearby
Addresses anywhere in the TW3 and TW4 postcode districts can book drive unit replacement through us. The engineer who attends works under our management and travels to the site. There is no branch in Hounslow, so the price, the booking and the paperwork all come from one place.
Space for materials and tools is limited at many addresses in Hounslow, especially on narrow or pedestrianised streets in Greater London. Larger door sets are delivered for the time of fitting, and access and parking restrictions are planned into the visit.
Nearby towns we also list for drive unit replacement (straight-line distance): Twickenham (1.9 miles), Richmond (2.4 miles), Feltham (2.7 miles), Southall (2.8 miles), Ealing (3.9 miles), Greenford (4.2 miles).
What to think about for drive unit replacement in Hounslow
- Older shopfronts in Hounslow 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.
- Business parks and office blocks in Hounslow with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Ask for the paperwork. A converted door should come with its risk assessment, Declaration of Conformity and user instructions, which belong with your building and maintenance records.
- 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
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.
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
- Start with a short enquiry. Use the form, phone or email. Tell us whether the work is a new door, an upgrade or an opener for a home, and we arrange the next step for your site in Hounslow.
- Measured survey. The free survey confirms what will fit and what the entrance needs: opening width, door type, activation, safety sensors and behaviour on power loss or fire alarm, matched to how the building is used.
- Written price, no surprises. A fixed, itemised quote sets out the specification, the work involved, the expected lead time and the warranty terms. You can ask questions or change the specification before accepting it.
- Installed and commissioned. The door is installed with as little disruption as possible, then set up and tested for its hazard zones. Before leaving, the engineer explains the controls and hands over the documents for your records.
If parts for your door in Hounslow 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 Hounslow: questions
Will you remove the old operator from our premises in Hounslow?
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.
What is the guide price for drive unit replacement in Hounslow?
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 Hounslow confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Can the replacement in Hounslow 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.
Do you replace automatic door drive units in Hounslow?
Yes. We are the contracting party for drive unit replacements in Hounslow, 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 happens once the installation in Hounslow is finished?
The engineer tests every function, including the safety sensors and the behaviour on power loss, and sets the door up with reference to BS EN 16005. You are shown how to use the controls and which simple checks to make, and you receive the handover documents, including the test record and any conformity paperwork that applies to the work.
What does the free site survey in Hounslow 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.
Who is responsible for automatic doors on escape routes in Hounslow?
Under the Regulatory Reform (Fire Safety) Order 2005 the responsible person for the premises must make sure escape routes work and fire safety equipment is maintained. Automatic doors on an escape route need fail-safe opening or break-out, set by the fire strategy.
