Covering Harrow and nearby
Homes, businesses and public buildings throughout the HA1, HA2 and HA3 postcode districts can arrange drive unit replacement with us. We are the contracting party and organise every visit; the engineer, who works under our management, travels in to Harrow for the job rather than working from premises in town.
Office entrances in Harrow commonly combine automatic doors with turnstiles, concierge desks and card access. When the operator is wired into those systems, staff pass through quickly, visitors are let in from reception and the building locks down outside working hours.
Nearby towns we also list for drive unit replacement (straight-line distance): Wembley (2.3 miles), Edgware (3.4 miles), Greenford (3.6 miles), Ruislip (3.9 miles), Bushey (4.6 miles), Ealing (4.8 miles).
What to think about for drive unit replacement in Harrow
- 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.
- 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.
- Older shopfronts in Harrow may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- If the door is on an escape route, the new drive unit must be set up to open, break out or be openable by hand, as the building's fire strategy requires.
- Worn floor guides and rollers can shorten the life of a new operator. It is often worth replacing them during the same visit rather than coming back later.

Standards and rules in England
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 Great Britain a new or converted powered door must meet the Supply of Machinery (Safety) Regulations 2008 before it is first used, and can carry the UKCA or the CE marking.
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 Harrow.
- 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 Harrow: questions
How long will our entrance in Harrow 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.
How are prices worked out for drive unit replacement in Harrow?
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 Harrow 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 Harrow?
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 Harrow 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.
How do you make sure the door works for disabled visitors in Harrow?
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.
Do I need permission from a landlord or the council before work in Harrow?
It depends on the building. Tenants usually need the landlord's written consent before changing an entrance, and some changes to a shopfront or external door need planning permission. The survey notes anything that may need consent. We can supply drawings and product details to support an application, but the owner or tenant makes it.
Do businesses in Harrow have to fit automatic doors?
No law says every building must have automatic doors. Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, and building regulations guidance in England calls for a powered door where an entrance door would otherwise be too heavy to open. An automatic door is often the simplest way to meet both.
