The energy renovation market in figures
Energy renovation is one of the most dynamic sectors of the French economy. Driven by government subsidies (MaPrimeRénov', CEE, eco-PTZ), rising energy prices, and thermal regulations, household demand has never been higher. Installers—heating engineers, electricians, and RGE-certified tradespeople—are facing a surge in demand as well as increased competition.

The race to capture this demand explains the boom in the energy renovation lead generation market, estimated at several hundred million euros in France.
What is an energy renovation lead?
An energy renovation lead is a qualified contact: someone who has expressed a concrete interest in renovation work (insulation, heat pump, photovoltaic panels, boiler, ventilation system, etc.). They are distinguished from a simple website visitor or newsletter subscriber by their stated intention to purchase.

Buying renovation lead databases: good idea or bad idea?
Buy renovation lead databases (CSV files of thousands of contacts) is a different practice from buying qualified leads. These databases compile contact information without verifying recent purchase intent. The contact rate is very low (2–5 %), the numbers are often outdated, and GDPR compliance is questionable if consent is not documented. Avoid them for direct sales prospecting.
Generating your own leads: strategies and real costs
Generate renovation installer leads Building your own acquisition engine internally involves creating a dedicated platform: an optimized website, advertising campaigns, local SEO, and social media presence. It's a medium-term investment, but one that offers complete independence and a cost per lead that is often lower than external purchasing once the ecosystem is in place.
🔍 Strategy 1 — Local SEO (organic search engine optimization)
Create pages optimized for queries like "heat pump installer [city]" or "solar panel installation [region]". Results in 4–12 months, but highly qualified, free leads over time. Requires content, backlinks, and a technically sound website.
Estimated cost: 500–2,000 €/month (agency or freelance) — cost per downlink lead at 5–15 € at maturity.
📢 Strategy 2 — Google Ads (paid search)
High-intent keyword campaigns such as "attic insulation quote" or "air-to-water heat pump price" offer immediate results but high bidding costs (€2–8 per click for energy-efficient renovations). These campaigns require an optimized landing page and rigorous conversion tracking.
Estimated cost: €1,000–€5,000/month media budget + management. Cost per lead: €20–€60 depending on keywords.
📱 Strategy 3 — Social Ads (Meta, TikTok)
Facebook and Instagram ads allow for precise socio-demographic targeting (homeowners, age range, geographic area). While they generate less immediate purchase intent than Google ads, they offer high volume and a competitive cost per lead with the right visuals and messaging.
Estimated cost: €500–€2,500/month. Cost per lead: €12–€35 depending on targeting.
🤝 Strategy 4 — Word-of-mouth and local partnerships
Customer referral program, partnerships with real estate agencies, notaries, CCAS (local social services), condominium managers. Often underutilized, this channel generates leads with very high conversion rates (the prospect comes recommended).
Estimated cost: Virtually no cash outlay, but significant sales time investment. Cost per lead: €5–15.

What strategy should you adopt based on your installer profile?
There is no universal answer. The best choice depends on your stage of development, your resources, and your time horizon.
🚀 Installer just starting out (0–2 years in business)
Recommendation: purchase leads. Your priority is to generate revenue quickly to validate your model. Buying leads allows you to fill your schedule without waiting the 6–12 months it takes for an SEO strategy to mature. Start with a test volume (20–50 leads) to validate your conversion rate and refine your sales pitch.
📈 Growing installer (2–5 years old, 3–10 employees)
Recommendation: hybrid approach. Continue buying leads to maintain volume, but simultaneously invest in your digital presence (website, Google My Business listing, customer reviews, some SEO content). Gradually, the proportion of self-generated leads will increase and reduce your overall acquisition cost.
🏆 Structured company (10+ employees, multiple warehouses)
Recommendation: prioritize internal generation. At this stage, either internalizing or outsourcing (to a specialized agency) your digital acquisition is the most cost-effective strategy. A monthly budget of €3,000–€8,000 for SEO and Ads can generate 150–400 qualified leads, representing a cost per lead of €10–€25, significantly lower than purchasing leads individually. Buying leads remains a useful supplementary tool for slow periods.
How to maximize ROI regardless of your approach
Whether you buy leads or generate them yourself, the final ROI depends less on the source than on your ability to convert them into customers. Here are the universal levers:
✅ 8 best practices to maximize your conversion
📊 Calculate its actual acquisition cost
Don't confuse the cost per lead with the customer acquisition cost (CAC). If you buy 100 leads at €30 each (€3,000) and convert 12 leads into customers (12 contracts), your CAC is €250. If your average order value is €8,000 and your margin is 35%, each customer generates €2,800 in gross profit. Your acquisition ROI is then... 11,2×. This simple calculation justifies investing more as soon as the ratio is positive.
⭐ What our installer clients say
I started by purchasing PAC leads, which allowed me to fill my schedule in two weeks. The return on investment is real: out of 40 leads purchased, I signed 6 contracts for a revenue of €48,000. I recommend it to any organization that wants to grow quickly.
Sébastien M. — Heat pump installer, Lyon (69)We tried buying databases online: disastrous. Since switching to a platform specializing in solar leads, our conversion rate has tripled. The prospects are genuinely interested and reachable.
Karine L. — Sales Manager, Bordeaux (33)It took us eight months to build our local SEO, but now we receive 30 quote requests per month without spending a single euro on advertising. The initial investment is significant, but the long-term return is incomparable. We reserve lead generation for seasonal lulls.

FAQ — Buying or generating leads for energy renovation
What is the average price of an energy renovation lead?
The price varies between €15 and €120 depending on the type of work, the qualification level, and the exclusivity of the lead. A shared insulation lead costs on average €15–€25, while an exclusive heat pump lead can reach €60–€120. Leads with confirmed appointments are the most expensive but have the best conversion rates (25–40 per 100,000). For a precise estimate tailored to your sector, consult our dedicated industry pages.
Are the purchased leads compliant with the GDPR?
Reputable platforms collect explicit consent from prospects when they fill out the form, in accordance with the GDPR. This consent is dated, tracked, and covers all commercial contact with partner tradespeople. As a buyer, you must ensure that your supplier provides proof of consent for each lead and that you have a legal basis for contacting them again. Avoid suppliers who do not document consent.
How long does it take to generate your own leads in energy renovation?
With SEO (search engine optimization), expect to see significant results in 4 to 12 months. Through Google Ads or Meta Ads, the first leads arrive within 48–72 hours of campaign launch, but it takes 1–3 months to optimize campaigns and achieve an acceptable cost per lead. Internal lead generation requires an initial investment (website, copywriting, campaign management) but generally becomes more profitable than purchasing leads after 12–18 months.
Is it better to buy exclusive or shared leads?
Exclusive leads cost two to four times more but offer a significantly higher conversion rate because you're not competing with other installers. If your current conversion rate is below 10% on shared leads, switching to exclusive leads can significantly improve your overall profitability. For tradespeople with limited sales time, exclusive leads are often more profitable despite the higher unit price.
What is a renovation leads database and why avoid it?
A renovation lead database is a file of contact information (name, phone number, email) compiled without verification of recent purchase intent. These contacts have not necessarily expressed a desire to be contacted by installers, which raises GDPR issues and generates very low contact rates (2–5 %). These should be distinguished from qualified leads generated via consent forms. Buy leads, not databases.
What is the best strategy for a solo tradesperson in energy renovation?
For a solo tradesperson, buying leads is generally the most pragmatic solution because it requires neither digital skills nor campaign management. Start with a small volume (15–20 leads/month), measure your conversion rate, and adjust accordingly. At the same time, optimize your Google My Business listing and collect customer reviews to strengthen your local credibility. This simple combination often generates 80% of the results for 20% of the effort.
How to compare the ROI between buying leads and internal generation?
Calculate your customer acquisition cost (CAC) for each source: total budget invested ÷ number of signed customers. Then compare this CAC to your gross margin per customer. If your CAC from purchased leads is €250 for a margin of €2,800, the ROI is very good. If your mature internal lead generation costs €80 in CAC for the same margin, it is clearly superior. For the first 12–18 months, purchasing leads is often more profitable; after that, internal generation takes over.
Can we combine lead buying and internal lead generation?
Absolutely, it's even the recommended strategy for growing businesses. Buying leads ensures an immediate and predictable flow of contacts, while internal lead generation (SEO, Ads, social media) gradually ramps up. Once internal generation is mature, it reduces reliance on external buying. Most high-performing RGE-certified companies maintain both channels in parallel to diversify their sources and secure their pipeline.
