Covering Molesey and nearby
We cover the whole of the KT8 postcode district, along with nearby towns in Surrey. 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.
Independent businesses in Molesey often have one entrance and cannot close for long. Work is usually scheduled early, late or on a quiet day, and where a door must be out of use for a period, we plan to keep the entrance usable or secure.
Nearby towns we also list for drive unit replacement (straight-line distance): Sunbury-on-Thames (1.7 miles), Walton-on-Thames (1.7 miles), Feltham (3.5 miles), Surbiton (3.6 miles), Twickenham (3.6 miles), Kingston upon Thames (3.7 miles).
What to think about for drive unit replacement in Molesey
- 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.
- 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.
- Doors linked to the fire alarm or access control in Molesey 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 Molesey make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.

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
- Send photos and the address. A few pictures of the door from both sides, the address in Molesey 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.
Send the make and model from the operator cover of your door in Molesey, and we will arrange a survey at no cost for a replacement drive unit.
Drive unit replacement in Molesey: questions
Do you replace automatic door drive units in Molesey?
Yes. We are the contracting party for drive unit replacements in Molesey, 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.
How much should I budget for drive unit replacement in Molesey?
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 Molesey 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 Molesey 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.
Will you remove the old operator from our premises in Molesey?
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.
Is there a warranty on drive unit replacement?
Yes. The warranty terms for the equipment and the installation are set out in your written quote, so you can see exactly what is covered before you accept. Keeping the door serviced at the recommended intervals helps keep it in good order, and the quote explains any conditions that apply to the warranty.
Can automatic doors be fitted to a listed building in Molesey?
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 Molesey 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.
