What to think about for automating an existing door in Derry/Londonderry
- Shop fronts on high streets in Derry/Londonderry often have narrow aluminium frames. The survey checks the transom can carry the operator without flexing, and whether it needs reinforcing.
- Older buildings in Derry/Londonderry often have heavy timber doors on floor springs. Some floor springs can be adapted, but many need replacing with hinges, which adds to the cost.
- Glass in a door that will be automated should be safety glass. Older doors in Derry/Londonderry may have panes that need replacing before the work goes ahead.
- Think about how the door is locked. If it is locked by key every night, an electric lock or keep may be worth adding so the door can be secured without switching the operator off.
- Schools and community buildings in Derry/Londonderry may prefer the work done in holidays or after hours. Ask for any out-of-hours working to be priced in the quote.

Standards and rules in Northern Ireland
In Northern Ireland, disability access duties come from the Disability Discrimination Act 1995, because the Equality Act 2010 does not apply there. Service providers and employers are expected to make reasonable adjustments, and an automatic door is a common one at entrances. Fitting an automatic door helps, but does not on its own guarantee those duties are met.
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.
How it works
- Tell us about the entrance. Send the address, a few photos and a rough size of the opening, and say how the door is used. That is enough for us to suggest options for automating an existing door and book a survey in Derry/Londonderry.
- Free site survey. A specialist engineer working under our management measures the opening, checks the frame, floor, head height and power, and talks through how people use the entrance. There is no charge and no obligation.
- Fixed written quote. You receive a fixed, itemised written quote with the specification, lead time, payment stages and warranty terms. The price does not change unless the scope does, and any change is agreed in writing first.
- Installation and handover. The door is fitted on the agreed dates, then set up, tested and documented with reference to BS EN 16005. You are shown the controls and the simple checks to make, and receive the handover paperwork.

Automating an existing door in Derry/Londonderry: questions
Will automating our door in Derry/Londonderry need planning permission?
Fitting an operator to an existing door does not usually need planning permission, but a listed building may need consent for fixings or new switches on the outside. In a conservation area, mounting the operator inside often avoids any change to the street view. Check with the planning authority if in doubt.

Our guide starts from £1,795 excluding VAT (per door), the same guide price we use across the UK. For homes that is from £2,154 including VAT.

Can you automate the existing doors at our building in Derry/Londonderry?
In most cases, yes. We check each door at a free survey, including the hinges, frame, glass, locks and power, and then quote a fixed price. If a door is not a good candidate, we explain why and what it would take to fix it, or quote a replacement instead.
Can you automate a fire door at our premises in Derry/Londonderry?
Usually, using an operator designed for fire doors and wired to the fire alarm so the door closes when the alarm operates. We check the door's rating and condition first. A fire door that does not close and seal properly needs repairing before an operator goes on.
How do you make sure the door works for disabled visitors in Derry/Londonderry?
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 does the written quote for automating an existing door in Derry/Londonderry include?
The quote lists each item separately: the door or equipment, installation, electrical connections where we provide them, removal of anything being replaced, testing and handover. It is a fixed price for the work described, so it does not change unless the scope changes, and any change is agreed with you in writing first.
Which marking should a new automatic door in Derry/Londonderry carry?
In Northern Ireland machinery carries the CE marking, with UKNI added where a UK body carried out the conformity assessment. The EU Machinery Regulation applies in Northern Ireland from 20 January 2027.
