Covering Harwich and nearby
Addresses anywhere in the CO12 postcode district can book drive unit replacement through us. The engineer who attends works under our management and travels to the site. There is no branch in Harwich, so the price, the booking and the paperwork all come from one place.
In Harwich, automatic door needs often centre on the high street: independent shops, pharmacies, banks, cafés and estate agents. Frontages are often narrow, so the choice is usually between a compact sliding door, a folding door or a swing operator on the existing door.
Nearby towns we also list for drive unit replacement (straight-line distance): Walton-on-the-Naze (6.5 miles), Ipswich (9.8 miles), Clacton-on-Sea (11.9 miles), Colchester (16.6 miles), Stowmarket (21.0 miles), Sudbury (24.5 miles).
What to think about for drive unit replacement in Harwich
- Older shopfronts in Harwich may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- 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.
- 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.
- 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.
- 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.

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.
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.
How it works
- Send photos and the address. A few pictures of the door from both sides, the address in Harwich 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 drive unit replacement 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.

Drive unit replacement in Harwich: questions
How long will our entrance in Harwich 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 much should I budget for drive unit replacement in Harwich?
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 Harwich confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Will you remove the old operator from our premises in Harwich?
Yes. The old drive unit, sensors and any other replaced parts are taken away as part of the job, and the work area is left clean. Disposal is included in the fixed quote, so there is nothing extra to arrange or pay for afterwards.
What if the frame of our door in Harwich is not worth keeping?
Then we will tell you. Damaged or corroded frames, glass that is not safety glass, or an opening that is too narrow for the people using it are all reasons to choose a new door instead. We can quote both options so you can compare them side by side.
What does the free site survey in Harwich involve?
An engineer working under our management visits the building, measures the opening, checks the frame, floor, head height and power supply, and looks at how people use the entrance. The survey is free and carries no obligation. Afterwards you receive a fixed, itemised written quote for drive unit replacement, with drawings where the door type needs them.
Can automatic doors be fitted to a listed building in Harwich?
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.
Which building regulations apply to a new automatic entrance in Harwich?
In England the guidance is Approved Document M (Volume 2) for access, Approved Document B for fire safety and escape routes, and Approved Document K for glazing and powered doors. A new entrance can count as building work, so building control should be involved before it is ordered.
