THE SHORT ANSWER
An exclusive, qualified heat pump lead in Brussels costs roughly EUR 90 to EUR 140 in 2026, average EUR 115. At 3 to 5 leads per customer that is about EUR 460 per acquired customer, 3.4 percent of a typical EUR 9,000 to EUR 18,000 project. Unlike Antwerp, Brussels does not carry a primary-market premium for heat pump leads here: it is priced at the national Belgium multiplier of 1.00.
Buying heat pump leads in Brussels: the 2026 price band
Brussels gets its own heat pump number here because installer competition and click prices are set locally, not nationally. What follows is the price of an exclusive heat pump lead in Brussels specifically, and what it takes to turn a batch of them into paying heat pump customers.
Price per exclusive lead in Brussels: EUR 90 to EUR 140, average EUR 115
Typical project value: EUR 9,000 to EUR 18,000
Exclusive leads needed per customer: 3 to 5
Cost per acquired customer: around EUR 460
City 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. Unlike Antwerp, Brussels does not carry a primary-market premium for heat pump leads here: it is priced at the national Belgium multiplier of 1.00.
When heat pump leads are cheapest in Brussels
Plan heat pump spend in Brussels around the calendar, not the invoice date: September to January is when demand is highest, June and July is when it empties out and buying gets cheaper but slower to convert.
How Brussels compares to the rest of Belgium
Brussels is one of four heat pump markets this model tracks in Belgium. Here is how the other three price against it:
Antwerp (multiplier 1.08) - EUR 97 to EUR 151 per exclusive lead
Ghent (multiplier 1.00) - EUR 90 to EUR 140 per exclusive lead
Liege (multiplier 1.00) - EUR 90 to EUR 140 per exclusive lead
None of that gap reflects a difference in how a heat pump lead is qualified. It is entirely a function of how many heat pump installers are bidding in that city's auction on a given week.
How buying heat pump leads in Brussels actually works
Buying heat pump leads in Brussels works the same way at every package size. You choose the postcodes and job types inside Brussels and the surrounding area, Flock matches homeowner requests against that filter, and each lead is delivered to you 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
Unused heat pump leads in a package roll over rather than expiring: the Flock Lead Promise means a quiet month in Brussels does not cost you the volume you already paid for, and there is no refund clause to negotiate around it.
What a Brussels customer actually costs you
3 to 5 exclusive heat pump leads is the normal range needed to land one job in Brussels. Multiply that by the EUR 115 average price and a heat pump customer costs around EUR 460, or 3.4 percent of a typical EUR 13,500 project.
Who you are actually selling to in Brussels
Two things decide whether a Brussels heat pump lead is worth chasing: who is behind it, usually a homeowner replacing a gas or oil boiler, and what is driving them, usually boiler replacement deadlines and running-cost comparisons. Get both from current heating system, insulation level, radiator type, ownership and timeline before you spend a call finding out.
How to test a heat pump lead supplier in Brussels without risking a quarter
Treat the first heat pump order in Brussels as an experiment, not a commitment. 15 exclusive leads gives you enough volume, at 3 to 5 leads per sale, to see a real pattern rather than noise.
Fix the Brussels postcodes and heat pump job types in writing before the first lead arrives.
Record time from heat pump lead creation to your first call attempt; above thirty minutes you are measuring your own follow-up, not the leads.
Track cost per acquired heat pump customer against the EUR 460 benchmark on this page, not cost per lead.
Agree the replacement rule for wrong area, wrong job type and unreachable numbers before you pay for the heat pump batch.
Confirm the heat pump price excludes VAT and is denominated in EUR.
Suppliers confident in their own heat pump quality in Brussels accept every one of those conditions, because the arithmetic already works in their favour.
