Our coverage in Chesham
In a town like Chesham, a single wall unit for a shop or a cassette for a surgery makes a real difference in summer. High Wycombe is about 13 km away.
Postcode districts we cover in Chesham include HP5. We also work in nearby Amersham, Berkhamsted and Chalfont St Peter. Buildings across Buckinghamshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

- Survey of the ceiling void depth and grid
- Compact 600 mm or full-size cassette selection

From enquiry to handover in Chesham
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Chesham we confirm access and parking beforehand.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Points to plan for in Chesham
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Conservation areas
Historic streets and listed buildings in and around Chesham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Leased premises
If your Chesham 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.
