How we work in Eltham

  1. Survey

    We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in Eltham we confirm access and parking beforehand.

  2. Design and quote

    You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.

  3. First fix

    Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.

  4. Install and test

    Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.

  5. Commission and hand over

    We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.

What to think about in Eltham

Power

Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.

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.

Landlord consent

Most commercial leases need the landlord's written consent before external units or wall penetrations go in. We can provide drawings and unit data sheets for the request.

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.

Typical premises in Eltham

  • 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 Eltham, we also cover Blackheath, Welling and Catford. Each has its own page with local guide prices.

Which postcodes do you cover in Eltham?

All of them, including SE9. Give us your postcode when you enquire and we will confirm the visit details.

How long does a commercial air conditioning installation take?

A single split system is usually fitted in a day. A small office or shop with three or four units typically takes two to four days, and a VRF system for a whole floor can take several weeks. We confirm the programme in the quote.

Which refrigerant will you use?

In Great Britain, new single split systems holding less than 3 kg of refrigerant cannot use a refrigerant with a global warming potential of 750 or more, so most are now R32. Larger systems may use R32, R454B or R410A depending on the equipment. We state the refrigerant and charge in the quote.
