Covering Cambridge and nearby
If your building is in Cambridge, or anywhere in the CB1, CB2, CB3, CB4 and CB5 postcode districts, we can arrange drive unit replacement. Visits are booked with you in advance, timed around opening hours where that matters, and carried out by engineers who work under our management.
Supermarkets and larger stores in and around Cambridge often trade long hours, so work on their entrances is usually planned for early mornings or late evenings. Where a store has more than one entrance, keeping one in use while the other is worked on is part of the plan.
Nearby towns we also list for drive unit replacement (straight-line distance): Newmarket (12.6 miles), Ely (15.1 miles), Huntingdon (15.7 miles), Haverhill (15.9 miles), St Neots (16.3 miles), Letchworth (21.1 miles).
What to think about for drive unit replacement in Cambridge
- 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.
- 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.
- Busy retail entrances in Cambridge may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- 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.
- Business parks and office blocks in Cambridge with several identical doors can replace operators in phases, keeping at least one entrance open at all times.

Standards and rules in England
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.
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
- 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 Cambridge.
- 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 Cambridge: questions
Can the replacement in Cambridge include a service plan?
It can. After the changeover we recommend a service interval based on how heavily the door is used, and a service contract can be set up with a written record of each visit. Servicing is priced separately and agreed in writing before any visit takes place.
What do you charge for drive unit replacement in Cambridge?
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 Cambridge 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 Cambridge?
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 you remove the old operator from our premises in Cambridge?
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 does the written quote for drive unit replacement in Cambridge 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.
How are payments structured for work in Cambridge?
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.
Do businesses in Cambridge 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.
