HVAC design and heat load surveys in Surrey

HVAC design and heat load surveys for businesses in Surrey — surveyed, designed and priced in writing before any work starts.

  • Design fees confirmed in writing first
  • Equipment, positions and price set out in writing
  • Work planned around your opening hours

How much does HVAC design cost in Surrey?

In Surrey, guide prices run from about £570 to £2,795 per project, plus VAT. A typical job (design package for a 300–800 m² office) usually comes to £1,150–£2,795 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.

Covering Surrey and nearby

Postcode districts we cover include CR3, GU6, GU19, GU27, KT15, KT23, RH8 and TW20. Buildings across Surrey range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

What the job covers

  • Room-by-room heat gain and heat loss calculations
  • System options with pros, cons and budget costs
  • Electrical load and supply requirements
  • Noise data for planning or landlord approval
  • Written specification for pricing

Things to check in Surrey

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.

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.

Premises we work in around Surrey

  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
  • Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

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).

Yes. Alongside Surrey, we also cover London, Berkshire and West Sussex. Each has its own page with local guide prices.

Why do I need a heat load calculation?

It sizes the system to what the room actually needs, avoiding oversized equipment that wastes money and undersized equipment that cannot cope.

Can you produce a specification for tender?

Yes. We produce drawings and a written specification so contractors price the same system.
