Covering Derby and nearby
Requests for drive unit replacement in Derby are handled by us and passed to a specialist engineer working under our management. Coverage includes the DE1, DE3, DE21, DE22, DE23 and DE24 postcode districts: town-centre premises, business and retail sites, public buildings and residential streets alike.
City-centre entrances tend to be the busiest doors of all: shopping centres, stations, hospitals and office towers can see thousands of passes a day. In Derby, that usually means heavy-duty operators, careful sensor set-up and servicing at intervals matched to the traffic.
Nearby towns we also list for drive unit replacement (straight-line distance): Belper (6.9 miles), Ilkeston (7.7 miles), Heanor (8.1 miles), Ripley (8.3 miles), Long Eaton (8.7 miles), Eastwood (9.1 miles).
What to think about for drive unit replacement in Derby
- 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 Derby with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- 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.
- 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.
- 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.

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.
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
- 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 Derby, 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.
Tired of repeat breakdowns at your entrance in Derby? Ask us to compare a new operator with a new door, so you can choose with both prices in front of you.
Drive unit replacement in Derby: questions
What if the frame of our door in Derby 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.
Can you give me a price for drive unit replacement in Derby?
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 Derby confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Will you remove the old operator from our premises in Derby?
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 fit a new operator to a door another company installed in Derby?
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.
Do you service doors in Derby after installing them?
Yes. We recommend a trained engineer checks the safety functions at least once a year, with service intervals set by the manufacturer's instructions and how heavily the door is used; busy doors are often serviced more often. Servicing can follow on from the installation, with the price agreed in writing and a record left after every visit.
What does the written quote for drive unit replacement in Derby 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.
Do businesses in Derby 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.
