THE SHORT ANSWER
An exclusive, qualified windows and doors lead in the United Kingdom costs roughly GBP 56 to GBP 89 in 2026, with GBP 72 as the working average. At a close rate of one in 5 that is about GBP 360 per acquired customer, or 5.0 percent of a typical GBP 4,250 to GBP 10,200 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 windows and doors lead costs in the United Kingdom in 2026
These are prices for an exclusive lead: a homeowner who asked for a quote, matched your service area and job type, and whose details go to you and nobody else. Shared leads, sold to four window and door companies at once, cost less per unit and more per customer.
Price per exclusive lead: GBP 56 to GBP 89, average GBP 72
Typical project value: GBP 4,250 to GBP 10,200
Exclusive leads needed per customer: 4 to 6
Cost per acquired customer: around GBP 360
Acquisition cost as a share of the job: about 5.0 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.
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.
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.
What separates a window and door lead that closes from one that does not
A stated frame count. A homeowner who knows they need nine frames has already walked the house; a homeowner who says some windows has not started. Material preference is the second signal, because it tells you whether they have visited a showroom or a website. Leads carrying both convert at a multiple of leads carrying neither, and both are form fields rather than call questions.
How a window and door lead behaves before it reaches you
This is a comparison category. Homeowners replacing frames almost always collect three quotes, and they compare on frame count, material and finish rather than on headline price, which makes an itemised quote far more persuasive than a discounted one. The enquiry usually follows a winter of draughts or a noise complaint, so the emotional trigger is comfort even when the stated reason is energy cost.
Why a more expensive lead is usually the cheaper one
The buyer behind these figures is a homeowner replacing single or early double glazing, and what moves them is draughts, noise and energy bills.
Filtering on number of frames, material preference, ownership and timeline removes 30 to 50 percent of raw form fills. The survivors cost more each and close far better. A GBP 89 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.
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.
Response time, priced in GBP
Reach rate on a windows and doors enquiry falls steeply with age: high inside five minutes, materially lower after thirty, and roughly halved by the following morning. Because the lead price is already paid, every unreachable lead transfers its cost onto the ones you do reach.
The arithmetic is unforgiving. If one lead in five goes unreachable purely through delay, your effective price per usable windows and doors lead rises from GBP 72 to about GBP 90, and your cost per customer with it. No supplier negotiation available anywhere in this market moves the number that far, which is why response time is the first thing to fix and the cheapest.
Practically: one named person owns the first call attempt, the target is under five minutes during working hours, and the metric you report weekly is median time to first attempt rather than number of leads received.
How the United Kingdom compares to the rest of Europe
Advertising auctions are local, so the same windows and doors 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 89 per exclusive lead
the Netherlands (multiplier 1.05) - GBP 54 to GBP 85 per exclusive lead
Sweden (multiplier 1.30) - GBP 66 to GBP 105 per exclusive lead
Italy (multiplier 0.95) - GBP 48 to GBP 77 per exclusive lead
The gap is not about lead quality. It is about how many window and door companies are bidding for the attention of the same homeowner in that auction.
Checklist before you buy windows and doors leads in the United Kingdom
Is the lead exclusive, or how many other window and door companies receive it?
Which British regions does it cover? London and the South East, the Midlands, the North West and Scotland behave very differently from rural areas on both price and close rate.
How old is the lead when it reaches you? Past thirty minutes, reach rate collapses.
What is the replacement policy for wrong numbers, wrong area or wrong job type?
Can you switch a postcode or job type off without renegotiating?
Is the price quoted excluding VAT, and in GBP?
A supplier who will not answer all six in writing is selling shared leads with a premium label.

Frequently asked questions
How much does a windows and doors lead cost in the United Kingdom?
Roughly GBP 56 to GBP 89 for an exclusive, qualified lead in 2026, with GBP 72 as the working average. Shared leads sell for less, typically GBP 28 to GBP 44, but they reach three to five window and door companies at the same time.
How many windows and doors 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 360, which is roughly 5.0 percent of a typical GBP 7,225 windows and doors 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.
What should I qualify a windows and doors lead on?
Number of frames, material preference, ownership and timeline. Those five answers remove 30 to 50 percent of raw enquiries and lift close rate more than any change to your pitch.
Does a cheaper windows and doors lead in the United Kingdom mean better economics?
Not on its own. What matters is cost per acquired customer against job value. At GBP 72 per lead and a typical GBP 7,225 project, acquisition runs at about 5.0 percent of revenue, and that percentage is the number to compare across markets.
