THE SHORT ANSWER
An exclusive, qualified insulation lead in France costs roughly EUR 51 to EUR 87 in 2026, with EUR 69 as the working average. At a close rate of one in 5.5 that is about EUR 380 per acquired customer, or 8.9 percent of a typical EUR 2,500 to EUR 6,000 project. France sits at a multiplier of 1.02 against a Benelux baseline of 1.0, because the Paris region behaves like a separate, more expensive market from the rest of the country, so a national average hides a factor of two.
Insulation lead prices in France: the 2026 band
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 insulation contractors at once, cost less per unit and more per customer.
Price per exclusive lead: EUR 51 to EUR 87, average EUR 69
Typical project value: EUR 2,500 to EUR 6,000
Exclusive leads needed per customer: 4 to 7
Cost per acquired customer: around EUR 380
Acquisition cost as a share of the job: about 8.9 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.
Response time, priced in EUR
Reach rate on a insulation 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 insulation lead rises from EUR 69 to about EUR 86, 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.
When insulation leads are cheapest in France
Insulation demand peaks in September to December and bottoms out around May to July, driven mostly by energy labels and heating bills.
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 insulation budget
Chasing subsidy traffic without checking eligibility. Subsidy-driven searches convert into enquiries at high rates and into work at low ones, because a large share of that traffic does not qualify. Filtering on ownership and building year at the form stage costs you volume and improves the economics considerably, and that trade is what this whole category runs on.
Subsidy schemes shape the enquiry
A large share of energy-related enquiries arrive already framed by a state scheme, which means the homeowner's expectations about cost and eligibility are set before you speak. Knowing the current position precisely is a competitive advantage, and it is also how you identify quickly which enquiries have no viable business case without the scheme.
How French homeowners buy
Written quotes are expected to be formal and complete, and the process is more paperwork-driven than in neighbouring markets. Homeowners frequently wait to compare documents rather than deciding on a call, which lengthens the cycle and rewards installers with a fast, professional document workflow over those relying on phone charm.
Why two insulation contractors in France report different figures for the same ads
At a 6 percent conversion rate, a insulation lead at EUR 69 implies a click price of roughly EUR 4. Lift that page to 12 percent and identical traffic delivers leads at about EUR 34 instead: no extra budget, half the cost per lead. This is the single biggest controllable variable in the whole calculation.
It is also why cost per lead benchmarks are argued about so much. Two insulation contractors in France can run the same campaign against the same auction and report figures that differ by a factor of two, entirely because of what happens after the click.
How many insulation leads a month your team can absorb
Volume is only useful up to the point your team can quote and deliver it. At 4 to 7 leads per customer, ten exclusive leads a month in this trade produce roughly 1 to 2 jobs, which at a typical EUR 4,250 project is somewhere around EUR 4,250 to EUR 8,500 of work landing in the diary.
Buy past that and the extra leads do not become extra jobs, they become slower callbacks on all of them. The pattern is consistent: businesses that raise volume before fixing quoting capacity see cost per acquired customer rise even though cost per lead is unchanged.
So set volume from installed capacity rather than from ambition, and raise it in steps you can staff. In France that usually means one increase per quarter, timed ahead of the September to December peak rather than during it.
What separates an insulation lead that closes from one that does not
Building year, and whether the target is cavity, roof or floor. Building year tells you the likely construction and therefore the likely method; the target area tells you the size of the job. Without both you cannot price and cannot even confirm feasibility, so the enquiry becomes a free site visit. Two form fields turn most of those visits into either a quote or a fast no.
How to test a insulation lead supplier in France 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 7 leads per customer that means at least 21 leads, and anything smaller measures luck rather than the supplier.
Fix the postcodes and job types in writing before the first lead arrives, using Ile-de-France, Auvergne-Rhone-Alpes, Occitanie and Nouvelle-Aquitaine 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 EUR 380 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 EUR.
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 insulation lead cost in France?
Roughly EUR 51 to EUR 87 for an exclusive, qualified lead in 2026, with EUR 69 as the working average. Shared leads sell for less, typically EUR 26 to EUR 44, but they reach three to five insulation contractors at the same time.
How many insulation leads do I need to win one job?
4 to 7 exclusive leads, assuming you call inside the first hour. On shared leads plan for two to three times that number.
When are insulation leads cheapest in France?
In the May to July trough. Demand peaks in September to December, 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 France?
Past roughly EUR 4,100 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 insulation leads for specific postcodes only?
Yes. Flock matches on postcode and job type, so you can run Ile-de-France, Auvergne-Rhone-Alpes, Occitanie and Nouvelle-Aquitaine and leave the rest of France alone. Narrowing the area raises the price per lead slightly and raises the close rate a lot more.
What should I qualify a insulation lead on?
Building year, surface area, cavity or roof, 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.
