THE SHORT ANSWER
An exclusive, qualified solar panel lead in the United Kingdom costs roughly GBP 84 to GBP 140 in 2026, with GBP 112 as the working average. At a close rate of one in 4 that is about GBP 448 per acquired customer, or 5.0 percent of a typical GBP 5,950 to GBP 11,900 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 solar panel 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 solar panel installers carries a lower sticker price and a higher cost per customer.
Price per exclusive lead: GBP 84 to GBP 140, average GBP 112
Typical project value: GBP 5,950 to GBP 11,900
Exclusive leads needed per customer: 3 to 5
Cost per acquired customer: around GBP 448
Acquisition cost as a share of the job: about 5.0 percent
A word on where these numbers come from. They are a benchmark model rather than a survey: an industry base range observed across Western European home-improvement campaigns, multiplied by a country factor for local auction pressure. Use them as a band to negotiate against, not as a quote.
What you really pay per acquired customer
Cost per lead in isolation tells you nothing. Divide it by your close rate.
At GBP 112 per lead and one sale per 4 leads, a new solar panel customer in the United Kingdom costs about GBP 448. On a GBP 8,925 project that is 5.0 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 56 for a lead that four competitors also received, and your close rate falls to one in twelve, your cost per customer becomes roughly GBP 672. That is worse than the exclusive lead, and it burns three times as much of your sales week.
Nations and regions price differently
London and the South East sit well above the rest of the country on both click price and job value, while the North and Scotland are cheaper on both. A single UK-wide campaign averages markets that behave nothing alike, and the resulting cost per lead figure is usually blamed on lead quality when the real cause is geography.
When solar panel leads are cheapest in the United Kingdom
Solar panel demand peaks in spring and early summer and bottoms out around November to January, driven mostly by electricity prices and payback-period anxiety.
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.
How a solar lead behaves before it reaches you
A homeowner researching solar typically spends six to ten weeks reading before filling in a single form, and by the time they do they have already settled on a rough system size and read at least one payback calculation. That changes the first call completely: you are not educating, you are being audited. The installers who win are the ones who can confirm or correct the homeowner's own numbers within two minutes, because the homeowner is comparing your answer against the two calculators they already ran.
Why the same solar panel lead costs less across the border
Advertising auctions are local, so the same solar panel 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 84 to GBP 140 per exclusive lead
the Netherlands (multiplier 1.05) - GBP 80 to GBP 134 per exclusive lead
Spain (multiplier 0.90) - GBP 69 to GBP 115 per exclusive lead
Italy (multiplier 0.95) - GBP 73 to GBP 121 per exclusive lead
The gap is not about lead quality. It is about how many solar panel installers are bidding for the attention of the same homeowner in that auction.
How British homeowners buy
Reviews and accreditation are checked early and heavily, and an installer without visible third-party proof is filtered out before the first call. Homeowners also expect a quote quickly and informally, which makes speed of response a stronger predictor of who wins than price. The combination rewards installers who invest in review volume as seriously as in advertising.
Where the break-even sits in the United Kingdom
Both work. The break-even is arithmetic, not ideology.
Running your own ads makes sense once monthly media spend passes roughly GBP 3,700 in this market, because at that point the fixed cost of a decent landing page, tracking and someone managing the account spreads thinly enough to beat a per-lead price.
Buying exclusive leads makes sense below that, and whenever you want to switch spend on and off with your capacity rather than commit to a retainer. You pay for outcomes and the supplier carries the auction risk.
Marketplaces and shared leads make sense only if your team genuinely calls inside five minutes, every time. If not, you are subsidising whichever competitor does.
What separates a solar lead that closes from one that does not
Roof orientation and roof age decide more solar deals than price does. A south-facing roof under fifteen years old converts at roughly double the rate of an east-west roof that needs work first, and a lead with no roof age answer is a lead that will stall at the survey stage. Ask for it on the form rather than on the call: the homeowner who will not answer it in writing is rarely the homeowner who signs.
How to test a solar panel 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 3 to 5 leads per customer that means at least 15 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 448 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 solar panel lead cost in the United Kingdom?
Roughly GBP 84 to GBP 140 for an exclusive, qualified lead in 2026, with GBP 112 as the working average. Shared leads sell for less, typically GBP 42 to GBP 70, but they reach three to five solar panel installers at the same time.
How many solar panel leads do I need to win one job?
3 to 5 exclusive leads, assuming you call inside the first hour. On shared leads plan for two to three times that number.
Why are solar panel leads more expensive in some countries?
Because the auction is local. The United Kingdom runs at a multiplier of 1.10 against the Benelux baseline, mainly because English-language auctions attract bidders from outside the country, which lifts click prices above what the local competitive density alone would justify.
When are solar panel leads cheapest in the United Kingdom?
In the November to January trough. Demand peaks in spring and early summer, so off-peak leads run 20 to 40 percent below the figures above. They convert more slowly, so only buy them if you have the follow-up discipline to nurture into the peak.
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.
Who is actually behind a solar panel enquiry in the United Kingdom?
Typically a homeowner comparing three quotes for a roof-mounted system, motivated by electricity prices and payback-period anxiety. Matching your first call to that motive rather than to your price list is what separates a 20 percent close rate from a 8 percent one.
