Covering Derry/Londonderry and nearby
We do not keep premises in Derry/Londonderry. Instead, enquiries about automatic sliding doors come to us, we agree the price in writing, and a specialist engineer working under our management travels to the address in the BT47 and BT48 postcode districts on a date that suits the site.
Around Derry/Londonderry 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 automatic sliding doors (straight-line distance): Strabane (13.6 miles), Limavady (14.7 miles), Coleraine (27.1 miles), Omagh (27.5 miles).
What to think about for automatic sliding doors in Derry/Londonderry
- Business park offices around Derry/Londonderry often have a reception door that is busy for an hour each morning and quiet for the rest of the day. A timer on the programme switch can lock it out of hours without anyone remembering to.
- Shops that use a roller shutter at night need the new header to sit below the shutter box and clear of its guide channels. Both are measured at survey so the door and shutter can work together.
- Where a building in Derry/Londonderry is listed or sits in a conservation area, a new entrance may need consent first. Slim frames, a colour matched to the existing shopfront and careful drawings can all help an application.
- Schools, libraries and council buildings often prefer installation during holidays or at weekends. That is usually possible, as long as the dates are known when the order is placed and the door can be made in time.
- Surgeries and clinics need wide, easy access for wheelchairs, walking frames and the occasional stretcher. A clear opening of at least 1,000 mm is, in our view, a sensible starting point, and wider still where trolleys or beds pass through.

Standards and rules in Northern Ireland
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 to buildings is in Technical Booklet R, and building control approval is needed for new entrances.
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
- Send photos and the address. A few pictures of the door from both sides, the address in Derry/Londonderry 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 automatic sliding doors 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.
Book a survey in Derry/Londonderry and an engineer will measure the opening, check the power and floor, and talk you through the sliding layouts that fit.
Automatic sliding doors in Derry/Londonderry: questions
How long will the doorway in Derry/Londonderry be out of action?
For a straightforward replacement, the opening is usually secure again by the end of the first day, with the door fully working by the end of the second. Larger shopfront changes take longer. How the doorway will be kept safe and secure overnight is agreed with you before work starts.
What is the guide price for automatic sliding doors in Derry/Londonderry?
Our guide is £4,495 to £12,995 excluding VAT (per door set), the same guide prices we use across the UK. The free site survey in Derry/Londonderry confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Who checks that a new sliding door in Derry/Londonderry is safe?
The installing engineer sets the speeds, forces and sensor zones, tests the door and completes a site-specific risk assessment before handing it over. You keep the test record and the risk assessment for your own files, and they form the baseline for every service visit and inspection after that.
Will a new sliding door in Derry/Londonderry work with our alarm and access control?
In most cases, yes. The operator can take signals from a fire alarm panel, a card reader, a keypad, an intercom or a timer. Tell us what you have at the survey, and the quote will show the interface work and who is responsible for each connection, whether that is us, your electrician or your alarm company.
How much disruption should we expect while the work is done in Derry/Londonderry?
Most installations take one visit or a short series of visits, with dust and noise kept to the area around the door. The engineer screens off the work area, keeps a route in or out where possible and clears up before leaving. Larger entrances, lobbies or structural changes take longer, and the quote explains how that work is phased.
What happens once the installation in Derry/Londonderry 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.
