Covering Harrow and nearby
Engineers working under our management travel to addresses across the HA1, HA2 and HA3 postcode districts for automating an existing door. There is no depot or showroom in Harrow; you arrange everything with us by phone, email or the form on this page, and we confirm the price in writing first.
Victorian and Georgian terraces are common across London, and converted buildings in Harrow may have steps, narrow hallways or shared front doors. A home door opener or an operator on a communal door has to work within those limits, and the engineer checks what will fit.
Nearby towns we also list for automating an existing door (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 automating an existing door in Harrow
- Power is needed at the head of the door. If there is no supply close by, an electrician will need to run one, ideally hidden in trunking or the wall.
- Listed buildings and conservation areas in Harrow may need consent for an operator on an original door. Mounting it on the inside face usually keeps the street view the same.
- Find out whether the door is a fire door. If it is, the operator must suit fire doors and be wired so the door closes when the alarm sounds.
- Glass in a door that will be automated should be safety glass. Older doors in Harrow may have panes that need replacing before the work goes ahead.
- Older buildings in Harrow 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.

Standards and rules in England
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.
Building regulations guidance in England (Approved Document M, Volume 2) says a powered opening system should be used where a self-closing entrance door would need more than 30 N at the leading edge to open, or more than 22.5 N between 30° and 60°, and expects external doors used by the public in new buildings to give at least 1000 mm of effective clear width.
How it works
- Send photos and the address. A few pictures of the door from both sides, the address in Harrow 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 automating an existing door 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.

Automating an existing door in Harrow: questions
Can you automate a front door at a house in Harrow?
Yes. Front doors at home are often automated for wheelchair users and people with limited grip, usually with an electric keep or lock so the door locks itself as it closes. Home prices are quoted including VAT, and the survey is free.
What price range should I expect for automating an existing door in Harrow?
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. 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.
Will automating our door in Harrow 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.
Can you automate a fire door at our premises in Harrow?
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.
Is there a warranty on automating an existing door?
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.
How are payments structured for work in Harrow?
Payment stages are set out in the quote before you accept it. Larger or made-to-order jobs may involve a deposit and a balance on completion, while smaller jobs may be invoiced once the work is finished. Nothing is charged for the survey itself, and the terms you accept are the terms that apply.
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.
