How much does office air conditioning cost in London?

Our guide range in London is £2,750–£6,350 per zone before VAT; a typical job (office of about 150 m² with 4–6 zones) is £11,450–£31,500 plus VAT. Your exact price is fixed in writing once we have surveyed.

Office air conditioning is a cooling and heating system designed for the heat loads of an office: people, computers, lighting and sunshine through glazing.

Working in London

We cover all of London, including Brent, Islington, Bexley, Barking and Sutton. Wherever your premises are, the survey, quote and installation follow the same steps.

Postcode districts we cover include BR1, E16, EN5, N16, SE7, SW8, W1 and WC2R. 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.

What is included

  • Heat load assessment per zone (occupancy, IT, lighting, solar gain)
  • Zoned design so meeting rooms can be controlled separately
  • Ceiling cassettes, ducted units or wall units to suit the ceiling
  • Coordination with your fit-out contractor, ceiling and lighting layout
  • Commissioning, handover and F-gas records

How it works in London

  1. Survey the floor

    We look at the ceiling void, the grid layout, window orientation, occupancy and where the outdoor plant can go.

  2. Zone the space

    Open-plan, meeting rooms, reception and IT rooms are treated as separate zones with their own controls.

  3. Coordinate the ceiling

    Unit positions are set against the lighting and grid layout so cassettes and grilles sit neatly. We keep work areas in London screened and tidy at the end of each day.

  4. Install around the business

    Work is phased by area or done out of hours so staff can keep working.

  5. Commission and train

    Controls are set with sensible limits and scheduling, and we show your facilities lead how to manage them.

Things to check in London

Fresh air

Air conditioning recirculates air; it does not provide fresh air on its own. Many offices need ventilation alongside it to meet the Building Regulations.

Working hours

Most London businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Out-of-hours use

If staff work late or weekends, zoning lets you run only the areas in use.

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.

Who we work with in London

  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

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 London

How much does office air conditioning cost in London?

Guide prices in London run from about £2,750 to £6,350 per zone, plus VAT. A typical job (office of about 150 m² with 4–6 zones) costs £11,450–£31,500 plus VAT. We fix the price in writing after a free survey.

Do you also cover Surrey, Hertfordshire and Essex?

Yes. Alongside London, we also cover Surrey, Hertfordshire and Essex. Each has its own page with local guide prices.

Does office air conditioning provide fresh air?

No — it heats and cools the air already in the room. Fresh air comes from ventilation, which we can design alongside the cooling.

Will it disrupt the office?

We phase work by area or work early mornings, evenings or weekends. Most of the noisy work is done before units are hung.
