How a job in Dorset works
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
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. In Dorset we agree timings around your opening hours.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Before you book in Dorset
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
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.
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 Dorset are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Types of premises we cover in Dorset
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
Common questions from businesses in Dorset
How much does a ceiling cassette cost in Dorset?
Guide prices in Dorset run from about £2,250 to £5,150 per cassette, plus VAT. A typical job (shop or restaurant with 2–3 cassettes) costs £5,150–£14,050 plus VAT. We fix the price in writing after a free survey.
Do you also cover the Isle of Wight, Hampshire and Wiltshire?
Yes. Alongside Dorset, we also cover the Isle of Wight, Hampshire and Wiltshire. Each has its own page with local guide prices.
What size cassette do I need?
It depends on the heat load. As a guide, a compact cassette suits a room of up to about 40–50 m² of office space; larger spaces use bigger units or several cassettes.
How noisy are ceiling cassettes?
At normal fan speeds modern cassettes are quiet enough for offices and restaurants. We select fan speeds and unit sizes so they are not working flat out.
