Covering Grantham and nearby
Coverage for automatic internal doors runs across the NG31 postcode district and out into the surrounding parts of Lincolnshire. Wherever the building is, the arrangements stay the same: one contracting party, a written price before work, and a specialist engineer working under our management on site.
In Grantham, 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 automatic internal doors (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 automatic internal doors in Grantham
- Offices in Grantham with open-plan floors often have corridor fire doors that are held open by wedges. A proper hold-open device or operator removes the wedge and keeps the door working as a fire door.
- Check the fire rating of each door before the survey. Fire doors need operators made for them, and fixings and cables must not weaken the rating.
- Plan the work around the building's routine. Clinical areas, classrooms and kitchens in Grantham may need out-of-hours working, which should be agreed and priced up front.
- Lightweight stud partitions may not carry an operator without extra support. The survey checks what the wall is made of and what reinforcement is needed.
- Noise matters on wards and in bedrooms. Ask for night settings or quieter operators on doors near where people sleep, and check how loud any electric locks are when they release.

Standards and rules in England
Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, which can include altering a physical feature such as a heavy entrance door. Fitting an automatic door helps, but does not on its own guarantee those duties are met.
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
- Start with a short enquiry. Use the form, phone or email. Tell us whether the work is a new door, an upgrade or an opener for a home, and we arrange the next step for your site in Grantham.
- Measured survey. The free survey confirms what will fit and what the entrance needs: opening width, door type, activation, safety sensors and behaviour on power loss or fire alarm, matched to how the building is used.
- Written price, no surprises. A fixed, itemised quote sets out the specification, the work involved, the expected lead time and the warranty terms. You can ask questions or change the specification before accepting it.
- Installed and commissioned. The door is installed with as little disruption as possible, then set up and tested for its hazard zones. Before leaving, the engineer explains the controls and hands over the documents for your records.

Automatic internal doors in Grantham: questions
Can you service the internal doors in Grantham after fitting?
Yes. We can arrange planned servicing with each door's operator, sensors and fire alarm release checked and a written record left. Servicing is chargeable, and the price per visit is agreed in writing before an engineer attends. Visits can be grouped so several doors are done together.
What price range should I expect for automatic internal doors in Grantham?
Our guide starts from £1,795 excluding VAT (per door), the same guide price 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.
Do you supply internal sliding doors as well as swing operators in Grantham?
Yes. Where there is wall space beside the opening, a sliding door keeps the corridor clear and gives a wide opening, which suits wards. Where there is not, or the door is a fire door, a swing operator is usually the better fit. The survey compares both.
Can you fit automatic doors in a school in Grantham?
Yes. Corridor fire doors, dining halls and doors to accessible facilities are common. We usually plan the work for school holidays or after hours, and agree the programme with the school in writing so safeguarding and fire arrangements are maintained throughout.
What power supply is needed for automatic internal doors in Grantham?
Most powered doors need a fused spur close to the operator, and some activation and access control devices also need a low-voltage link. The survey checks what is already there. If a new supply is required, the quote says whether we arrange it or your own electrician does, so nothing is left unclear on the day.
What is the lead time for automatic internal doors in Grantham?
Lead times depend on the door type and what has to be made to order. As a guide, operators and accessible door kits are typically two to four weeks from order, and complete sliding entrances typically four to eight weeks from drawing approval. Curved, revolving and hermetic doors usually take longer. The expected lead time is stated in your quote.
Which building regulations apply to a new automatic entrance in Grantham?
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.
