Local points to consider
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Leased premises
If your Northampton premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Future use
Allow for growth in occupancy or IT load.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Types of premises we cover in Northampton
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.

- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
