How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. If a freeholder or agent needs to agree the work in New Cross, we can send them the details.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.

About our air conditioning in New Cross
Any installation we do in New Cross follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. Air con, air conditioning, a split system: whatever you call it, in New Cross it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Across London, and in New Cross too, a lot of air conditioning goes into flats and terraces rather than detached houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

For landlords and property managers
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Why act early in New Cross
Planning ahead beats a rushed decision in a heatwave. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. Booking the survey early gives you time to weigh up the options. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Questions from New Cross
Do I need permission to put air conditioning in my flat in New Cross?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is New Cross in your area for air conditioning?
We do: New Cross falls inside our working area. To start, ring us on 07833 053749, or email if that’s easier with a few pictures.
Can I have air conditioning in a flat?
Often, yes, but there are extra steps. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls and the lease will say. Planning rules for flats are tighter too, so we point out anything that may need permission on the survey. This is general information, not legal advice.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
How long does it take to fit air conditioning?
It takes about a day for a single-room system, longer for multi-room and ducted systems. The survey tells us how long your installation will need, so you can plan around it.
What affects the cost of air conditioning
The diagnosis comes before the price. We look at:
- What kind of system it is
- One-off work versus a regular service cycle
- The size of the job
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll go through it with you.
Helping us quote
When you contact us, these details help:
- A short video of any fault, such as a noise or a flashing light

What an install looks like in New Cross
About 43% of homes across New Cross and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 73% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Older streets near St James's Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. Close to New Cross station? A small study or box room used for work can typically be cooled with a single indoor unit.
