Covering Farnham and nearby
Sites across the GU9 and GU10 postcode districts are visited by specialist automatic door engineers working under our management. They travel to Farnham 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.
GP surgeries, dental practices and pharmacies in Farnham often serve older patients and people with limited mobility. A low-energy swing operator, or a gentle sliding door with a push pad, can make a real difference at entrances like these.
Nearby towns we also list for drive unit replacement (straight-line distance): Aldershot (2.8 miles), Fleet (5.0 miles), Farnborough (5.8 miles), Bordon (7.5 miles), Godalming (8.3 miles), Alton (8.8 miles).
What to think about for drive unit replacement in Farnham
- Business parks and office blocks in Farnham with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- 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.
- Listed buildings and conservation areas in Farnham make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- 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.
- Doors linked to the fire alarm or access control in Farnham need those links rewired to the new controller. Let us know which systems connect to the door.

Standards and rules in England
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.
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
- Tell us about the entrance. Send the address, a few photos and a rough size of the opening, and say how the door is used. That is enough for us to suggest options for drive unit replacement and book a survey in Farnham.
- Free site survey. A specialist engineer working under our management measures the opening, checks the frame, floor, head height and power, and talks through how people use the entrance. There is no charge and no obligation.
- Fixed written quote. You receive a fixed, itemised written quote with the specification, lead time, payment stages and warranty terms. The price does not change unless the scope does, and any change is agreed in writing first.
- Installation and handover. The door is fitted on the agreed dates, then set up, tested and documented with reference to BS EN 16005. You are shown the controls and the simple checks to make, and receive the handover paperwork.

Drive unit replacement in Farnham: questions
Can you fit a new operator to a door another company installed in Farnham?
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 do you charge for drive unit replacement in Farnham?
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 Farnham 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 Farnham 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.
Can the replacement in Farnham 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.
What power supply is needed for drive unit replacement in Farnham?
Most powered doors need a fused spur close to the operator, and some activation and access control devices also need a low-voltage link. The survey checks what is already there. If a new supply is required, the quote says whether we arrange it or your own electrician does, so nothing is left unclear on the day.
What happens once the installation in Farnham 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.
Do businesses in Farnham 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.
