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 Erith before it is booked.

What to think about for drive unit replacement in Erith
- Business parks and office blocks in Erith with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- 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.
- 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.
- 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.
- 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.

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.
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 Erith.
- 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 Erith 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 Erith: questions
Can you fit a new operator to a door another company installed in Erith?
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 Erith?
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 Erith 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 Erith?
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 if the frame of our door in Erith 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.
Will the building stay secure while the entrance is being changed?
We plan to keep the entrance usable or secure throughout. Where a door has to come out, the work is sequenced so the opening is closed up before the engineer leaves, or a temporary door or hoarding is arranged when a longer gap cannot be avoided. How this is handled for your site in Erith is agreed before work starts.
What does the written quote for drive unit replacement in Erith include?
The quote lists each item separately: the door or equipment, installation, electrical connections where we provide them, removal of anything being replaced, testing and handover. It is a fixed price for the work described, so it does not change unless the scope changes, and any change is agreed with you in writing first.
Which building regulations apply to a new automatic entrance in Erith?
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.
