Most installers won't put a price on their website. Here's mine, along with an honest explanation of why a 1930s semi in Petts Wood costs more to do than a new flat in Bromley — and why there's no VAT to add to any of it.
A typical single-room installation in a local home. Fixed in writing after a free survey — no day-rate surprises, no "extras" invented halfway through.
These are starting prices for homes in Bromley, Orpington, Petts Wood and Chislehurst. Your survey turns the starting price into a fixed price — and if your house is a straightforward one, it stays where it started.
One indoor unit, one outdoor condenser. The most common job by a distance: a bedroom that's unbearable in July, or a south-facing home office.
Two indoor units running from one outdoor condenser. Usually two bedrooms, or a bedroom and a living room. Cheaper than two separate systems and only one condenser on the wall.
Whole-upstairs or whole-house systems. Worth doing in one visit rather than piecemeal — one condenser, one set of scaffolding or access, one lot of making good.
Already have air conditioning? A full clean and health check — filters, indoor and outdoor coils, condensate drain, electrics and controls. Available right now.
Why some prices say "quoted at survey". Because I'm not going to make a number up to fill a table. A two-room system in a Chislehurst detached and a two-room system in a Bromley flat are different jobs with different pipe runs, different access and different amounts of making good. I'd rather come and look, then give you a figure I'll stand behind, than post a headline price and revise it upwards on the day. The survey is free and there's no pressure at the end of it.
Smith EcoFlow isn't VAT-registered, so there is no VAT to add to the price I quote you. A larger firm quoting the same £1,450 has to add 20% on top before you pay.
It's not a promotion and there's no catch — it's simply how a small father-and-son firm is set up. On a bigger multi-room job, the difference stops being pocket change.
The unit on the wall is rarely what changes the cost. It's the pipe run, the access and the making good — and round here, that's decided by what kind of house you're in.
The classic local house. If the bedroom you want cooled is above the side return, the pipe run is short and you're at the bottom of the price range. If it's the front bedroom over the bay, the run has to travel round the flank wall to reach a sensible condenser position — more pipe, more trunking, and usually a tower or ladder work at first floor. Same unit, different day's work.
Usually the easiest houses to do well and the most likely to want more than one room done. Plenty of external wall to work with and somewhere sensible to put a condenser out of sight. The thing to watch is the conservation areas — if you're inside one, the position of the outdoor unit matters and may need consent from the borough. I'll flag that at the survey, not after.
Often the cheapest install and the most likely to hit a paperwork problem. The pipe run is usually short and straight, which keeps the price down. But almost every leaseholder needs written consent from the freeholder or managing agent before a condenser goes on an external wall or balcony. Get that moving early — it takes longer than the installation does.
The single most common reason people in this area call me. Loft rooms bake — heat rises, the insulation traps it, and a fan just moves warm air around. It's also the room where a long pipe run down to ground level is most likely, so it's rarely the cheapest install. It is, however, the one that makes the biggest difference to whether the room is usable in summer.
Gary and Connor. Two people, one van, and a phone that gets answered by the person who'll be doing the work. Based in Orpington, working in the streets we live on.
I live in Orpington. Bromley, Petts Wood and Chislehurst are fifteen minutes from my front door — not a "coverage area" on a map.
That matters more than it sounds. I've been in the plumbing and building trade for 15 years, and my day job is running planned maintenance on a large commercial air conditioning estate. I know what the houses round here are built like, where the pipework can realistically go, and what a job like yours actually takes.
It also means that if something needs looking at afterwards, I'm not dispatching someone from an hour away. You get me.
Straight about certification: my F-Gas certification (City & Guilds 2079) completes on 7 September 2026. Charging refrigerant into a system legally requires it, so I'm surveying, quoting and holding installation dates now, and installing from September. Servicing existing air conditioning doesn't involve the refrigerant circuit — that I can do today.
Booking early costs you nothing and secures a date. September fills up quickly, and the people who called in July will be at the front of it.
Tell me which room, and roughly what's driving you mad about it. Two minutes on the phone tells me most of what I need.
I come and look properly — where the unit goes, where the condenser goes, how the pipe gets between them. Evenings and Saturdays if that's easier.
A written quote you can hold me to, with no VAT to add. If the answer is that your house is awkward and it'll cost more, I'll say so then.
Your date is held from September. Most single-room installs are done in a day, and the house is left as we found it.
Free survey, written quote, no VAT to add and no pressure at the end of it. Bromley, Orpington, Petts Wood and Chislehurst.
