THE SHORT ANSWER
An exclusive, qualified windows and doors lead in Belgium costs roughly EUR 60 to EUR 95 in 2026, average EUR 78. At 4 to 6 leads per customer that is about EUR 390 per acquired customer, 4.6 percent of a typical EUR 5,000 to EUR 12,000 project. Belgium sits at a multiplier of 1.00 against a Benelux baseline of 1.0, because Flanders and Wallonia behave like two different auctions: Dutch-language clicks are more expensive because installer density is higher there
Buying windows and doors leads in Belgium: the 2026 price band
These prices are for an exclusive windows and doors lead bought nationally in Belgium: a homeowner who asked for a windows and doors quote, matched to your service area and job type, and passed to you and nobody else. Shared leads reaching several window and door companies at once cost less per unit and more per customer once the lost jobs are counted.
Price per exclusive lead in Belgium: EUR 60 to EUR 95, average EUR 78
Typical project value: EUR 5,000 to EUR 12,000
Exclusive leads needed per customer: 4 to 6
Cost per acquired customer: around EUR 390
Country multiplier applied: 1.00
These figures are a benchmark model, not a survey. They combine an industry base range observed across Western European home-improvement campaigns with a country multiplier for local auction pressure. Treat them as a band to negotiate against, not a quote.
When windows and doors leads are cheapest in Belgium
Plan windows and doors spend in Belgium around the calendar, not around the invoice date: late winter and spring is when demand is highest, August is when it empties out and buying gets cheaper but slower to convert.
How Belgium compares to other national markets
Before committing windows and doors budget to Belgium alone, it helps to see how the same lead prices in three other markets this model covers:
Belgium (multiplier 1.00) - EUR 60 to EUR 95 per exclusive lead
Spain (multiplier 0.90) - EUR 54 to EUR 86 per exclusive lead
Poland (multiplier 0.60) - EUR 36 to EUR 57 per exclusive lead
the United Kingdom (multiplier 1.10) - EUR 66 to EUR 105 per exclusive lead
None of that difference reflects a better or worse windows and doors homeowner behind the form. It is entirely a function of local installer density and click prices.
How buying windows and doors leads in Belgium actually works
Buying windows and doors leads nationally in Belgium works the same way at every package size. You choose the postcodes and job types you want covered, Flock matches homeowner requests against that filter across the country, and each lead is delivered within minutes of the request, never to a second business at the same time.
Starter - 10 leads for EUR 750, which is EUR 75 per lead
Growth - 25 leads for EUR 1,750, which is EUR 70 per lead
Scale - 45 leads for EUR 2,925, which is EUR 65 per lead
Pro - 70 leads for EUR 4,340, which is EUR 62 per lead
Max - 90 leads for EUR 5,400, which is EUR 60 per lead
No windows and doors volume is ever lost to a quiet week: under the Flock Lead Promise, unused leads anywhere in Belgium simply carry forward, rollover rather than refund.

What a Belgium customer actually costs you

Frequently asked questions
What does that make my cost per acquired customer in Belgium?
About EUR 390, which is roughly 4.6 percent of a typical EUR 8,500 windows and doors project.
How does Belgium compare to other countries for this industry?
See the comparison section on this page: three other markets are set side by side, and the differences are almost entirely driven by local installer density.
How fast are leads delivered once a homeowner enquires in Belgium?
Within minutes of the request. Flock does not batch or queue leads, and each one goes to you alone, never to a second business.
Can I buy leads for specific regions of Belgium only?
Yes. Flock matches on postcode and job type, so you can cover Antwerp and Ghent and leave the rest of Belgium alone if that suits your capacity.
What happens to leads I do not use this month in Belgium?
They roll over rather than expire, under the Flock Lead Promise. There is no refund, but there is also no lost volume.
What should I qualify a windows and doors lead on before quoting in Belgium?
Number of frames, material preference, ownership and timeline. Those answers remove 30 to 50 percent of raw enquiries before they reach a call.
Can I test a windows and doors lead supplier in Belgium before committing to volume?
Yes, and you should. Buy a small batch sized to expect two or three sales, track cost per acquired customer rather than cost per lead, and agree the replacement rules in writing first.
