Covering Boston and nearby
Engineers working under our management travel to addresses across the PE21 postcode district for drive unit replacement. There is no depot or showroom in Boston; you arrange everything with us by phone, email or the form on this page, and we confirm the price in writing first.
Doors at quieter sites in Boston and elsewhere in Lincolnshire can go many years between checks. A safety inspection looks at how the sensors, closing behaviour and emergency functions are working, and gives you a written record to keep on file.

What to think about for drive unit replacement in Boston
- 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.
- Business parks and office blocks in Boston with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Listed buildings and conservation areas in Boston make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- 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.
- Doors linked to the fire alarm or access control in Boston need those links rewired to the new controller. Let us know which systems connect to the door.

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
- 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 drive unit replacement and book a survey in Boston.
- 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.

Drive unit replacement in Boston: questions
How long will our entrance in Boston 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 is the guide price for drive unit replacement in Boston?
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 Boston confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Can you fit a new operator to a door another company installed in Boston?
Yes. We replace drive units on doors whoever fitted them. The survey identifies the existing header, leaves and track, and adapter plates usually let a new drive unit from one of the major European operator brands fit without changing the frame.
Will you remove the old operator from our premises in Boston?
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 happens once the installation in Boston is finished?
The engineer tests every function, including the safety sensors and the behaviour on power loss, and sets the door up with reference to BS EN 16005. You are shown how to use the controls and which simple checks to make, and you receive the handover documents, including the test record and any conformity paperwork that applies to the work.
What does the written quote for drive unit replacement in Boston 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.
Who is responsible for automatic doors on escape routes in Boston?
Under the Regulatory Reform (Fire Safety) Order 2005 the responsible person for the premises must make sure escape routes work and fire safety equipment is maintained. Automatic doors on an escape route need fail-safe opening or break-out, set by the fire strategy.
