Covering Purley and nearby
We do not keep premises in Purley. Instead, enquiries about drive unit replacement come to us, we agree the price in writing, and a specialist engineer working under our management travels to the address in the CR8 postcode district on a date that suits the site.
Getting a van close to the door is often the hardest part of a London job. Red routes, controlled parking zones and loading rules vary from street to street, so access and parking restrictions are planned into the visit to Purley before it is booked.
Nearby towns we also list for drive unit replacement (straight-line distance): Carshalton (3.2 miles), Croydon (3.3 miles), Sutton (3.9 miles), Caterham (4.0 miles), Mitcham (5.2 miles), Morden (5.6 miles).
What to think about for drive unit replacement in Purley
- 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.
- Hospitals and care homes in Purley may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.
- Older shopfronts in Purley may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- Heavy glass leaves need an operator rated for their weight. The survey records the size and glass type of each leaf so the right drive unit is specified.
- Listed buildings and conservation areas in Purley 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
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.
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 Purley, 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.

Drive unit replacement in Purley: questions
Do you provide paperwork for the converted door in Purley?
Yes. When we fit a new drive unit we prepare the paperwork for the finished door, including the risk assessment, Declaration of Conformity and user instructions, and hand it over with the test results and settings. It belongs with your building records.
What price range should I expect for drive unit replacement in Purley?
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 Purley confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
What lead time should we expect in Purley?
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.
Can you fit a new operator to a door another company installed in Purley?
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 do you make sure the door works for disabled visitors in Purley?
We look at who uses the entrance: wheelchair users, people with walking aids, parents with buggies and older visitors. That shapes the opening width, the opening speed, the hold-open time and where push pads or sensors go. Service providers and employers have duties to make reasonable adjustments under equality and accessibility law, and an automatic door is a common one.
What power supply is needed for drive unit replacement in Purley?
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.
Who is responsible for automatic doors on escape routes in Purley?
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.
