What to think about for drive unit replacement in Dorking
- Doors linked to the fire alarm or access control in Dorking need those links rewired to the new controller. Let us know which systems connect to the door.
- Business parks and office blocks in Dorking 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.
- Hospitals and care homes in Dorking may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.
- 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.

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
- 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 Dorking.
- 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.

Drive unit replacement in Dorking: questions
Will you remove the old operator from our premises in Dorking?
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 price range should I expect for drive unit replacement in Dorking?
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 Dorking 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 Dorking 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.
Can you fit a new operator to a door another company installed in Dorking?
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 are payments structured for work in Dorking?
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.
What happens to the old door when a new one is fitted in Dorking?
If the work replaces an existing door, frame or operator, removal and disposal are listed in the quote. The old door comes out only when the new one is ready to go in, so the opening is not left empty for longer than necessary. Making good to the surrounding wall, floor or ceiling is included where the quote says so.
Do businesses in Dorking 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.
