Covering Welling and nearby
Homes, businesses and public buildings throughout the DA16 postcode district can arrange drive unit replacement with us. We are the contracting party and organise every visit; the engineer, who works under our management, travels in to Welling for the job rather than working from premises in town.
Frontages in Welling can be narrow, and many London streets include listed buildings or conservation areas where changes to a shopfront need consent. Slimline operators and folding doors are often the practical options, as is a discreet operator fitted to the existing door.
Nearby towns we also list for drive unit replacement (straight-line distance): Bexleyheath (1.4 miles), Sidcup (2.5 miles), Eltham (2.5 miles), Woolwich (2.7 miles), Thamesmead (2.9 miles), Erith (3.2 miles).
What to think about for drive unit replacement in Welling
- 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.
- Listed buildings and conservation areas in Welling make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Doors linked to the fire alarm or access control in Welling need those links rewired to the new controller. Let us know which systems connect to the door.
- Older shopfronts in Welling may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- Hospitals and care homes in Welling 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
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.
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
- 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 Welling, 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.
Send the make and model from the operator cover of your door in Welling, and we will arrange a survey at no cost for a replacement drive unit.
Drive unit replacement in Welling: questions
Do you replace automatic door drive units in Welling?
Yes. We are the contracting party for drive unit replacements in Welling, and the survey and changeover are carried out by specialist engineers we manage. The survey is free and checks that the frame and leaves are worth keeping. You then receive a fixed, itemised quote for the new operator, sensors and any other parts the door needs.
How are prices worked out for drive unit replacement in Welling?
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 Welling 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 Welling?
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.
How long will our entrance in Welling 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 does the free site survey in Welling involve?
An engineer working under our management visits the building, measures the opening, checks the frame, floor, head height and power supply, and looks at how people use the entrance. The survey is free and carries no obligation. Afterwards you receive a fixed, itemised written quote for drive unit replacement, with drawings where the door type needs them.
What is the lead time for drive unit replacement in Welling?
Lead times depend on the door type and what has to be made to order. As a guide, operators and accessible door kits are typically two to four weeks from order, and complete sliding entrances typically four to eight weeks from drawing approval. Curved, revolving and hermetic doors usually take longer. The expected lead time is stated in your quote.
Do businesses in Welling 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.
