Covering Lisburn and nearby
Engineers working under our management travel to addresses across the BT27 and BT28 postcode districts for drive unit replacement. There is no depot or showroom in Lisburn; you arrange everything with us by phone, email or the form on this page, and we confirm the price in writing first.
Around Lisburn there is usually a mix of retail parks, business parks and town-centre shops, each with different door needs. A retail park unit may need a wide bi-parting door for trolleys, while a town-centre shop often has a narrow frontage better suited to a single slider or a folding door.
Nearby towns we also list for drive unit replacement (straight-line distance): Belfast (6.7 miles), Dundonald (10.6 miles), Newtownabbey (10.7 miles), Holywood (11.6 miles), Comber (11.8 miles), Lurgan (12.6 miles).
What to think about for drive unit replacement in Lisburn
- 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 Lisburn with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- 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.
- Busy retail entrances in Lisburn may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- 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 Northern Ireland
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 Northern Ireland machinery, including a new or converted powered door, carries the CE marking (with UKNI added where a UK body carried out the conformity assessment), and the EU Machinery Regulation applies there from 20 January 2027.
Workplace law (the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993) 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 Lisburn.
- 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.
Keep the frame, replace the drive. Arrange a free survey in Lisburn and receive a fixed quote covering the new operator, sensors and paperwork.
Drive unit replacement in Lisburn: questions
What lead time should we expect in Lisburn?
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.
What is the guide price for drive unit replacement in Lisburn?
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 Lisburn confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
How long will our entrance in Lisburn 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.
Will you remove the old operator from our premises in Lisburn?
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 do you make sure the door works for disabled visitors in Lisburn?
We look at who uses the entrance: wheelchair users, people with walking aids, parents with buggies and older visitors. That shapes the opening width, the opening speed, the hold-open time and where push pads or sensors go. Service providers and employers have duties to make reasonable adjustments under equality and accessibility law, and an automatic door is a common one.
What do you need from us for parking and access in Lisburn?
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 accessibility law applies in Lisburn?
In Northern Ireland the Disability Discrimination Act 1995 applies, because the Equality Act 2010 does not extend there. Service providers and employers are expected to make reasonable adjustments for disabled people, and an automatic door is a common one at entrances.
