Covering Grantham and nearby
Sites across the NG31 postcode district are visited by specialist automatic door engineers working under our management. They travel to Grantham for drive unit replacement as bookings come in, so dates depend on the diary rather than a fixed local team, and we give you the earliest date we can offer when you book.
Parking on a busy high street can be tight. When work is booked in Grantham, the engineer's arrival is planned around loading restrictions, any market days and opening hours, so the visit causes as little disruption as possible.
Nearby towns we also list for drive unit replacement (straight-line distance): Sleaford (11.4 miles), Newark-on-Trent (13.0 miles), Melton Mowbray (14.3 miles), Oakham (17.3 miles), Carlton (19.0 miles), Stamford (19.2 miles).
What to think about for drive unit replacement in Grantham
- Busy retail entrances in Grantham may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- Doors linked to the fire alarm or access control in Grantham need those links rewired to the new controller. Let us know which systems connect to the door.
- Business parks and office blocks in Grantham with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Battery backup is easier to add with a new drive unit. It lets the door open or close safely in a power cut, which matters most on escape routes.
- 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.

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
- Get in touch. Call, email or use the form with the address and what you have in mind. If you are not sure which type of door suits, describe the entrance and we will suggest the options worth considering.
- Survey and advice. The survey costs nothing and carries no obligation. The engineer checks the site and explains which options suit the entrance, the people using it and the budget, before anything is priced.
- Quote in writing. You receive a fixed, itemised quote for drive unit replacement in Grantham, covering equipment, installation, testing and handover, with the lead time and payment stages set out clearly.
- Install, test, explain. The engineer installs and commissions the door, tests the sensors, safety functions and emergency behaviour, and walks you through the controls. The handover pack records what was installed and tested.
Keep the frame, replace the drive. Arrange a free survey in Grantham and receive a fixed quote covering the new operator, sensors and paperwork.
Drive unit replacement in Grantham: questions
Can the replacement in Grantham 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.
What price range should I expect for drive unit replacement in Grantham?
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 Grantham confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
How long will our entrance in Grantham 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 lead time should we expect in Grantham?
Once the quote is accepted, drive units are typically 2 to 4 weeks to arrive, depending on the length and weight rating needed. The changeover date is agreed with you as soon as the parts are confirmed, and it can be planned around your opening hours.
Can automatic doors be fitted to a listed building in Grantham?
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.
Will the building stay secure while the entrance is being changed?
We plan to keep the entrance usable or secure throughout. Where a door has to come out, the work is sequenced so the opening is closed up before the engineer leaves, or a temporary door or hoarding is arranged when a longer gap cannot be avoided. How this is handled for your site in Grantham is agreed before work starts.
Who is responsible for automatic doors on escape routes in Grantham?
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.
