How much does HVAC design cost in London?
In London, guide prices run from about £635 to £3,150 per project, plus VAT. A typical job (design package for a 300–800 m² office) usually comes to £1,250–£3,150 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.

Points to plan for in London
Future use
Allow for growth in occupancy or IT load.
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.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
