Covering Larne and nearby
Our coverage of Larne takes in the BT40 postcode district and the neighbouring parts of County Antrim. If your address sits close to a boundary, it is still covered: send the postcode with your enquiry about drive unit replacement and we will confirm the arrangements and the price in writing.
Many buildings in Larne are older, with timber frames, thick walls, steps or uneven thresholds. These affect where an operator and sensors can go, and the engineer checks them on site before anything is fitted or adjusted.
Nearby towns we also list for drive unit replacement (straight-line distance): Carrickfergus (9.3 miles), Ballyclare (10.0 miles), Newtownabbey (13.6 miles), Dundonald (17.8 miles).
What to think about for drive unit replacement in Larne
- Business parks and office blocks in Larne 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 Larne need those links rewired to the new controller. Let us know which systems connect to the door.
- 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.
- 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.
- Hospitals and care homes in Larne may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.

Standards and rules in Northern Ireland
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 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.
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 Larne, 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.

Drive unit replacement in Larne: questions
Do you provide paperwork for the converted door in Larne?
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.
Can you give me a price for drive unit replacement in Larne?
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 Larne 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 Larne?
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.
How long will our entrance in Larne 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 should I send before the survey in Larne?
A few photos of the door from inside and outside, rough measurements of the opening, the address and a note of how the entrance is used. If the door already has an operator, a photo of any label on it helps. With that, the engineer arrives prepared, the survey takes less of your time and we can put the quote for drive unit replacement together more easily.
How do you make sure the door works for disabled visitors in Larne?
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 the building regulations in Northern Ireland say about powered doors?
The Building Regulations (Northern Ireland) 2012 require a powered door to have a means to prevent it trapping anyone and a means to open it if the power fails. Guidance on access is in Technical Booklet R, and new entrances need building control approval.
