THE SHORT ANSWER
An exclusive, qualified air conditioning lead in the United Kingdom costs roughly GBP 56 to GBP 94 in 2026, with GBP 75 as the working average. At a close rate of one in 5 that is about GBP 375 per acquired customer, or 8.0 percent of a typical GBP 2,550 to GBP 6,800 project. The United Kingdom sits at a multiplier of 1.10 against a Benelux baseline of 1.0, because English-language auctions attract bidders from outside the country, which lifts click prices above what the local competitive density alone would justify.
What a air conditioning lead costs in the United Kingdom in 2026
Everything below is priced for an exclusive lead, meaning one homeowner who requested a quote, fits your postcodes and job types, and is passed to you alone. A shared lead reaching four HVAC installers carries a lower sticker price and a higher cost per customer.
Price per exclusive lead: GBP 56 to GBP 94, average GBP 75
Typical project value: GBP 2,550 to GBP 6,800
Exclusive leads needed per customer: 4 to 6
Cost per acquired customer: around GBP 375
Acquisition cost as a share of the job: about 8.0 percent
These are modelled figures, not scraped ones. The industry base band comes from Western European home-improvement campaign performance and is then adjusted for how competitive the local auction is. Any individual quote can sit outside the band for good reasons, so treat it as a reference point rather than a price list.
Why a more expensive lead is usually the cheaper one
The buyer behind these figures is a homeowner or small office that wants cooling before summer, and what moves them is heatwaves and home-office comfort.
Filtering on number of rooms, building type, existing ducting and timeline removes 30 to 50 percent of raw form fills. The survivors cost more each and close far better. A GBP 94 lead you can actually service beats a GBP 34 lead you have to refuse, and the refused lead is not free: it costs a call, a diary slot and a small amount of your team's belief in the channel.
Seasonality: the discount nobody books
Air conditioning demand peaks in the first heatwave and bottoms out around December to February, driven mostly by heatwaves and home-office comfort.
Off-peak leads typically run 20 to 40 percent below the figures above, but they take longer to convert and more of them go cold. Buying volume in the trough and nurturing into the peak is the cheapest growth available in this trade, and almost nobody does it because it requires spending money in the month the phone is quiet.
The mistake that wastes the most air conditioning budget
Running the same budget all year. Off-season cooling clicks are cheap and close to worthless, while heatwave clicks are expensive and convert immediately. Flat monthly spend guarantees you underbuy in the two weeks that matter and overbuy in the ten months that do not, which is why per-lead buying with a switch suits this trade better than a fixed retainer.
An English-language auction with outside bidders
Because the auction runs in English, UK campaigns compete with international advertisers who are not selling installation at all. That lifts click prices above what local competitive density alone would justify, and it means benchmarking UK cost per lead against a comparable non-English market usually understates what you should expect to pay.
Currency and quoting
Prices in this market are quoted and compared in pounds, so a supply arrangement denominated in another currency introduces a variance you cannot control. It is worth agreeing which currency the price is fixed in before volume starts, because a few percent of exchange movement is a meaningful share of the margin on a single lead.
Cost per customer, not cost per lead
Cost per lead in isolation tells you nothing. Divide it by your close rate.
At GBP 75 per lead and one sale per 5 leads, a new air conditioning customer in the United Kingdom costs about GBP 375. On a GBP 4,675 project that is 8.0 percent of revenue. The working rule across home-improvement trades is that a healthy acquisition cost sits between 4 and 9 percent of job value. Above 12 percent, either the lead quality or the follow-up is broken, and it is almost always the follow-up.
Now compare that to a shared lead. If you pay GBP 38 for a lead that four competitors also received, and your close rate falls to one in twelve, your cost per customer becomes roughly GBP 456. That is worse than the exclusive lead, and it burns three times as much of your sales week.
What separates an air conditioning lead that closes from one that does not
Building type and existing ducting. A single room in an apartment with no position for an external unit is a different job to a house with a plant location and cable runs already in place, and the difference decides whether the enquiry is viable at all. Asking about the number of rooms and the building type on the form filters out a meaningful share of enquiries that cannot physically be served.
How the United Kingdom compares to the rest of Europe
Advertising auctions are local, so the same air conditioning lead is not worth the same everywhere. Against a Benelux baseline of 1.0, the United Kingdom runs at 1.10. All figures are converted to GBP so they can be read side by side. For the same industry:
the United Kingdom (multiplier 1.10) - GBP 56 to GBP 94 per exclusive lead
the Netherlands (multiplier 1.05) - GBP 54 to GBP 89 per exclusive lead
Poland (multiplier 0.60) - GBP 31 to GBP 51 per exclusive lead
France (multiplier 1.02) - GBP 52 to GBP 87 per exclusive lead
The gap is not about lead quality. It is about how many HVAC installers are bidding for the attention of the same homeowner in that auction.
How to test a air conditioning lead supplier in the United Kingdom without risking a quarter
Buy a small, defined batch rather than signing a retainer, and decide in advance what success looks like. For this trade at these prices, a fair test is enough leads to expect two or three sales: at 4 to 6 leads per customer that means at least 18 leads, and anything smaller measures luck rather than the supplier.
Fix the postcodes and job types in writing before the first lead arrives, using London and the South East, the Midlands, the North West and Scotland as your reference area.
Record time from lead creation to your first call attempt. If that number is above thirty minutes, you are measuring your own follow-up, not the leads.
Track cost per acquired customer against the GBP 375 benchmark on this page rather than cost per lead.
Agree the replacement rule for wrong area, wrong job type and unreachable numbers.
Confirm the price is exclusive of VAT and denominated in GBP.
Suppliers who are confident in their own quality accept every one of those conditions, because they know the arithmetic works in their favour.

Frequently asked questions
How much does a air conditioning lead cost in the United Kingdom?
Roughly GBP 56 to GBP 94 for an exclusive, qualified lead in 2026, with GBP 75 as the working average. Shared leads sell for less, typically GBP 28 to GBP 47, but they reach three to five HVAC installers at the same time.
How many air conditioning leads do I need to win one job?
4 to 6 exclusive leads, assuming you call inside the first hour. On shared leads plan for two to three times that number.
What does that make my cost per customer?
About GBP 375, which is roughly 8.0 percent of a typical GBP 4,675 air conditioning project. Anything under 9 percent is healthy for this trade.
Is it cheaper to run my own ads in the United Kingdom?
Past roughly GBP 3,700 a month in media spend, usually yes, because the fixed costs of page, tracking and management start to spread. Below that, buying exclusive leads is almost always the better arithmetic, and it flexes with your capacity.
Can I buy air conditioning leads for specific postcodes only?
Yes. Flock matches on postcode and job type, so you can run London and the South East, the Midlands, the North West and Scotland and leave the rest of the United Kingdom alone. Narrowing the area raises the price per lead slightly and raises the close rate a lot more.
Who is actually behind a air conditioning enquiry in the United Kingdom?
Typically a homeowner or small office that wants cooling before summer, motivated by heatwaves and home-office comfort. Matching your first call to that motive rather than to your price list is what separates a 17 percent close rate from a 7 percent one.
