Covering Sevenoaks and nearby
From shops and surgeries to schools, care homes and private houses, any building in the TN13 and TN14 postcode districts can be covered for drive unit replacement. Specialist engineers working under our management carry out the work, and you deal with us as the contracting party from start to finish.
Many buildings in Sevenoaks are older, with timber frames, thick walls, steps or uneven thresholds. These affect where an operator and sensors can go, and the engineer checks them on site before anything is fitted or adjusted.
Nearby towns we also list for drive unit replacement (straight-line distance): Tonbridge (6.5 miles), Orpington (8.1 miles), Swanley (8.6 miles), Tunbridge Wells (10.2 miles), Sidcup (11.2 miles), Caterham (11.6 miles).
What to think about for drive unit replacement in Sevenoaks
- 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.
- 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.
- Ask for the paperwork. A converted door should come with its risk assessment, Declaration of Conformity and user instructions, which belong with your building and maintenance records.
- 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.
- Busy retail entrances in Sevenoaks may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.

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
- 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 Sevenoaks.
- 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.
Send the make and model from the operator cover of your door in Sevenoaks, and we will arrange a survey at no cost for a replacement drive unit.
Drive unit replacement in Sevenoaks: questions
Will you remove the old operator from our premises in Sevenoaks?
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.
Can you give me a price for drive unit replacement in Sevenoaks?
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 Sevenoaks 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 Sevenoaks?
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 lead time should we expect in Sevenoaks?
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.
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 Sevenoaks is agreed before work starts.
What power supply is needed for drive unit replacement in Sevenoaks?
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.
Which building regulations apply to a new automatic entrance in Sevenoaks?
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.
