Covering Chelmsford and nearby
We do not keep premises in Chelmsford. Instead, enquiries about drive unit replacement come to us, we agree the price in writing, and a specialist engineer working under our management travels to the address in the CM1 and CM2 postcode districts on a date that suits the site.
Health centres, GP surgeries and clinics around Chelmsford need doors that open gently and stay open long enough for patients using walking aids or wheelchairs. Low-energy operators, push pads and careful sensor set-up matter more here than sheer speed.
Nearby towns we also list for drive unit replacement (straight-line distance): Billericay (7.7 miles), Witham (8.5 miles), Maldon (8.8 miles), Wickford (8.9 miles), Braintree (10.5 miles), Brentwood (10.6 miles).
What to think about for drive unit replacement in Chelmsford
- 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 Chelmsford with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Doors linked to the fire alarm or access control in Chelmsford need those links rewired to the new controller. Let us know which systems connect to the door.
- 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.
- Hospitals and care homes in Chelmsford may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.

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
- Send photos and the address. A few pictures of the door from both sides, the address in Chelmsford and a note of who uses the entrance help us understand the job before anyone visits the site.
- No-cost survey on site. We arrange a survey at a time that suits the building. The engineer records measurements, fixings and power, plus any constraints such as listed status, opening hours or access for deliveries.
- Itemised quote to approve. We price every element of the work on drive unit replacement separately in a written quote that you can check, share and approve. Lead time and payment stages are stated, and nothing is ordered until you accept.
- Fit, test and hand over. On the agreed dates the engineer installs the equipment, commissions the operator and tests each safety function. You get a demonstration, the test record and any conformity paperwork that applies to the work.
If parts for your door in Chelmsford 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 Chelmsford: questions
Can the replacement in Chelmsford 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.
How are prices worked out for drive unit replacement in Chelmsford?
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 Chelmsford confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
What if the frame of our door in Chelmsford 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 long will our entrance in Chelmsford 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.
What happens once the installation in Chelmsford is finished?
The engineer tests every function, including the safety sensors and the behaviour on power loss, and sets the door up with reference to BS EN 16005. You are shown how to use the controls and which simple checks to make, and you receive the handover documents, including the test record and any conformity paperwork that applies to the work.
What do you need from us for parking and access in Chelmsford?
Somewhere for the engineer's van as close to the entrance as possible, and a clear working area around the door. If parking is restricted, loading rules apply or the site has security procedures, tell us when you book. Those details go into the plan so the visit is not held up on the day.
Do businesses in Chelmsford 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.
