Dereham and surrounding areas
Dereham is a smaller town in Norfolk, with independent shops, offices, surgeries, pubs and local business units. Norwich is about 25 km away.
That includes premises in NR19 and the surrounding districts. Neighbouring towns we cover include Norwich, Thetford and King's Lynn. In Dereham, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.

From enquiry to handover in Dereham
Survey and route
We check void depths and plan routes for supply and return ductwork.
Design the air side
Grille sizes and positions are chosen for even air flow and low noise.
Install unit and ducts
The unit is hung with access for servicing; ductwork and grilles are fitted. In Dereham we agree timings around your opening hours.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Points to plan for in Dereham
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Leased premises
If your Dereham 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.
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
Conservation areas
Historic streets and listed buildings in and around Dereham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
