Covering Morden and nearby
We cover the whole of the SM4 postcode district, along with nearby towns in Greater London. You book each visit for drive unit replacement directly with us, and a specialist automatic door engineer working under our management travels to your site on the agreed date.
Space for materials and tools is limited at many addresses in Morden, especially on narrow or pedestrianised streets in Greater London. Larger door sets are delivered for the time of fitting, and access and parking restrictions are planned into the visit.
Nearby towns we also list for drive unit replacement (straight-line distance): Mitcham (1.3 miles), Wimbledon (1.7 miles), Tooting (2.4 miles), Carshalton (2.5 miles), Sutton (3.3 miles), Streatham (3.6 miles).
What to think about for drive unit replacement in Morden
- 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 Morden make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- 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.
- If the door is on an escape route, the new drive unit must be set up to open, break out or be openable by hand, as the building's fire strategy requires.
- 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.

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 Morden.
- 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.
If parts for your door in Morden 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 Morden: questions
Do you provide paperwork for the converted door in Morden?
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 will drive unit replacement in Morden cost?
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 Morden 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 Morden?
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.
Do you replace automatic door drive units in Morden?
Yes. We are the contracting party for drive unit replacements in Morden, 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.
Can installation in Morden happen outside opening hours?
Yes. Many shops, surgeries and offices prefer work early in the morning, in the evening or at weekends, when the entrance is quietest. Tell us your constraints when you enquire and they are built into the plan. Any extra cost for out-of-hours work is shown in the written quote rather than added afterwards.
What do you need from us for parking and access in Morden?
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.
Which building regulations apply to a new automatic entrance in Morden?
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.
