Heston and surrounding areas

Heston sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.

That includes premises in TW5 and the surrounding districts. Neighbouring towns we cover include Hounslow, Isleworth and Southall. 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 you get

  • Survey of the ceiling void depth and grid
  • Pipework, condensate pump and drain connection
  • Fresh-air spigot connection where ventilation ductwork is available
  • Wired controller or central control
  • Commissioning and F-gas records

How it works in Heston

  1. Check the void

    We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Heston we confirm access and parking beforehand.

  2. Set positions

    Cassettes are placed against the lighting and grid layout so air reaches the whole space.

  3. Hang and connect

    Units are hung on drop rods, connected to pipework and the condensate line.

  4. Test and commission

    The condensate pump is water-tested, the system pressure tested and charged, and air directions set.

What to think about in Heston

Condensate

Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.

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.

Void depth

Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.

Leased premises

If your Heston 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.

Types of premises we cover in Heston

  • Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
  • Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
  • Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing 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.

Questions about ceiling cassettes in Heston

How much does a ceiling cassette cost in Heston?

Guide prices in Heston run from about £2,750 to £6,350 per cassette, plus VAT. A typical job (shop or restaurant with 2–3 cassettes) costs £6,350–£17,295 plus VAT. We fix the price in writing after a free survey.

Do you also cover Hounslow, Isleworth and Southall?

Yes. Alongside Heston, we also cover Hounslow, Isleworth and Southall. Each has its own page with local guide prices.

Which postcodes do you cover in Heston?

All of them, including TW5. Give us your postcode when you enquire and we will confirm the visit details.

Do I need a suspended ceiling for a cassette?

Yes, or a ceiling void with access. In solid ceilings a wall-mounted or ducted unit is usually the better option.

What size cassette do I need?

It depends on the heat load. As a guide, a compact cassette suits a room of up to about 40–50 m² of office space; larger spaces use bigger units or several cassettes.
