Covering Derry/Londonderry and nearby

Weather matters for entrances that face open car parks, which is common on retail and business parks around Derry/Londonderry and elsewhere in County Londonderry. Exposed doors can be pushed by wind and let heat escape, so draught lobbies, good seals and correctly set sensors are worth considering.
Nearby towns we also list for telescopic 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 telescopic sliding doors in Derry/Londonderry
- Power for the operator usually comes from a fused spur at the head of the door. Where the nearest supply is some distance away, plan for an electrician to run a new circuit before the fitting day.
- A telescopic header is deeper than a standard one. In older buildings in Derry/Londonderry with low ceilings or decorative fanlights, the survey checks whether the header can sit above the opening or needs to be recessed.
- Grit and leaves blown into the threshold collect in floor guide channels. Entrances facing a car park or open ground benefit from a matwell or canopy, which also keeps rain off the sensors.
- Medical centres in Derry/Londonderry often share a frontage with a pharmacy or other units. Check who owns the shopfront and whether the landlord needs to approve a new entrance before the survey drawing is finalised.
- Floor guides on two sets of leaves need a level, firm floor. Cracked screed, rocking tiles or a sloping threshold should be put right before fitting, and the quote will say who does it.

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 telescopic 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.

Telescopic sliding doors in Derry/Londonderry: questions
Can you fit telescopic sliding doors in Derry/Londonderry?
Yes. We arrange supply and installation in Derry/Londonderry and the rest of County Londonderry. Specialist automatic door engineers working under our management carry out the survey and the fitting, and we stay the contracting party throughout, so one company is responsible for the drawing, the quote, the installation and the handover paperwork.
How are prices worked out for telescopic sliding doors in Derry/Londonderry?
Our guide starts from £6,995 excluding VAT (per door set), the same guide price 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.
Do we need to close our building in Derry/Londonderry while the door is fitted?
Usually not for long. Most telescopic entrances take one to two days on site, and the opening can be secured overnight. Where the entrance is the only way in, we plan the work around your hours, use another entrance if there is one, or work early or at weekends, with any extra cost shown in the quote.
Can you look after the door in Derry/Londonderry once it is installed?
Yes. We can quote planned servicing for the new door, with each visit priced in writing beforehand and the interval set by how heavily the door is used and the manufacturer's instructions. Busy entrances such as hospitals and supermarkets are usually serviced more often than quieter offices.
Is there a warranty on telescopic sliding doors?
Yes. The warranty terms for the equipment and the installation are set out in your written quote, so you can see exactly what is covered before you accept. Keeping the door serviced at the recommended intervals helps keep it in good order, and the quote explains any conditions that apply to the warranty.
Can automatic doors be fitted to a listed building in Derry/Londonderry?
Often, yes, but listed building consent is normally needed for changes that affect the character of the building, inside or out. Slim operators, concealed fixings and automating the existing door can all reduce the visual impact. Speak to the conservation officer at the local planning authority early; we can provide drawings and specifications to help.
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.
