How much does HVAC design cost in Dorset?
In Dorset, guide prices run from about £515 to £2,550 per project, plus VAT. A typical job (design package for a 300–800 m² office) usually comes to £1,050–£2,550 plus VAT. Your exact price is fixed in writing before any work starts.
An HVAC design and heat load survey works out how much heating and cooling each space needs — from occupancy, equipment, lighting, glazing, orientation and the building fabric — and sets out the system type, unit sizes and positions, pipe and duct routes and controls in a written specification.

Before you book in Dorset
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Working hours
Most Dorset businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Premises we work in around Dorset
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
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).
