Covering Grantham and nearby
Businesses in Grantham range from independent shops and restaurants to offices, clinics and warehouses. Nottingham is about 34 km away.
That includes premises in NG31 and the surrounding districts. We also work in nearby Newark-on-Trent, Melton Mowbray and Oakham. Buildings across Lincolnshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Heat source
Heat pump air curtains are usually cheaper to run than electric ones.
Access and parking
Town-centre jobs in Grantham often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Exposure
Windy entrances need more powerful units or a lobby.
Conservation areas
Historic streets and listed buildings in and around Grantham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Grantham
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
