How much does HVAC design cost in Greenford?

Our guide range in Greenford is £635–£3,150 per project before VAT; a typical job (design package for a 300–800 m² office) is £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.

Our coverage in Greenford

Premises in Greenford are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.

Postcode districts we cover in Greenford include UB6. We also work in nearby Northolt, Southall and Brent. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

  • Electrical load and supply requirements
  • Written specification for pricing

What to think about in Greenford

Future use

Allow for growth in occupancy or IT load.

Leased premises

If your Greenford 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.

Coordination

Ceiling, lighting, sprinkler and electrical layouts are coordinated early.

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.

Types of premises we cover in Greenford
