What to think about for drive unit replacement in Marlow
- Listed buildings and conservation areas in Marlow make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Hospitals and care homes in Marlow may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.
- Busy retail entrances in Marlow may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- Doors linked to the fire alarm or access control in Marlow need those links rewired to the new controller. Let us know which systems connect to the door.
- 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
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.
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
- 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 Marlow.
- 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.
If parts for your door in Marlow 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 Marlow: questions
What if the frame of our door in Marlow 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.
How much should I budget for drive unit replacement in Marlow?
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 Marlow confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you provide paperwork for the converted door in Marlow?
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.
How long will our entrance in Marlow 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.
Do I need permission from a landlord or the council before work in Marlow?
It depends on the building. Tenants usually need the landlord's written consent before changing an entrance, and some changes to a shopfront or external door need planning permission. The survey notes anything that may need consent. We can supply drawings and product details to support an application, but the owner or tenant makes it.
How do you make sure the door works for disabled visitors in Marlow?
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.
Which building regulations apply to a new automatic entrance in Marlow?
In England the guidance is Approved Document M (Volume 2) for access, Approved Document B for fire safety and escape routes, and Approved Document K for glazing and powered doors. A new entrance can count as building work, so building control should be involved before it is ordered.
