What to think about for drive unit replacement in County Londonderry
- Busy retail entrances in County Londonderry may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- Listed buildings and conservation areas in County Londonderry make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Hospitals and care homes in County Londonderry may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.
- Ask for the paperwork. A converted door should come with its risk assessment, Declaration of Conformity and user instructions, which belong with your building and maintenance records.
- 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
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.
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
- Describe what you need. Whether the job is drive unit replacement for a busy entrance or for a single internal door, a brief description and some photos let us understand it and plan a survey visit in County Londonderry.
- Free visit to the site. An engineer working under our management assesses the opening, the existing door and frame, the floor and the electrical supply, and notes any access, consent or timing issues to plan around.
- Your fixed quotation. The quote is fixed for the work it describes and lists each item, including any removal, making good and electrical work. It also states the lead time, the payment stages and the warranty terms.
- Fitting and sign-off. Work goes ahead on dates agreed with you. Once fitted, the door is adjusted and its safety functions are tested and recorded with reference to BS EN 16005, and you are shown how to use it.

Drive unit replacement in County Londonderry: questions
How long will our entrance in County Londonderry 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 price range should I expect for drive unit replacement in County Londonderry?
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 County Londonderry confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you provide paperwork for the converted door in County Londonderry?
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 the replacement in County Londonderry include a service plan?
It can. After the changeover we recommend a service interval based on how heavily the door is used, and a service contract can be set up with a written record of each visit. Servicing is priced separately and agreed in writing before any visit takes place.
Do you service doors in County Londonderry after installing them?
Yes. We recommend a trained engineer checks the safety functions at least once a year, with service intervals set by the manufacturer's instructions and how heavily the door is used; busy doors are often serviced more often. Servicing can follow on from the installation, with the price agreed in writing and a record left after every visit.
What happens to the old door when a new one is fitted in County Londonderry?
If the work replaces an existing door, frame or operator, removal and disposal are listed in the quote. The old door comes out only when the new one is ready to go in, so the opening is not left empty for longer than necessary. Making good to the surrounding wall, floor or ceiling is included where the quote says so.
Which accessibility law applies in County Londonderry?
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.
