Renov.lu grew out of the experience of homeowners who carried out several renovation projects in Luxembourg and ran into the same difficulties: understanding the exact process, working out the combined grants and the cost of a project, and finding trustworthy companies charging fair prices. Its founder, Yacine Sahnoune, spent several years in Luxembourg real estate, notably at atHome.lu, and takes a close interest in renovation and renewable energy. On the support side, Thomas answers homeowners’ questions about energy renovation, solar panels and heat pumps. The legal details are in the legal notice.
What renov.lu does, and what it does not
Renov.lu does three things: it explains works, their prices and the grants available in Luxembourg in free guides, it calculates a first estimate with simulators, and it forwards your quote request to partner companies; it carries out no works, is not a public body and signs no contract on your behalf.
| Renov.lu does | Renov.lu does not |
|---|---|
| Guides by type of works, in French, English and German, including renovating a building together: co-ownership renovation | Carry out works or sell equipment |
| Free simulators, no registration: energy renovation, heat pump, solar panels, air conditioning, renovation works | Pay or process grants: the state and its administrations do |
| Forward your request to companies established in Luxembourg, across 25 trades | Sign a contract or guarantee works: the chosen company alone is responsible |
The simulators’ estimates are based on average prices and grant values: they replace neither a site visit, nor a quote, nor the opinion of the body that manages the grant concerned. For neutral, free advice on energy grants, Klima-Agence answers on 8002 11 90.
How prices and grant amounts are established
The grant amounts published on renov.lu come from official texts (laws, grand-ducal regulations, guichet.lu pages) with their conditions and dates; prices are market ranges surveyed from companies established in Luxembourg, presented as such and never attributed to a public body.
- Grants: every amount is checked against its source. Example: Klimabonus Wunnen follows the law of 24 July 2026, which pays flat rates rather than percentages, with a temporary top-up until 30 June 2027. Measures announced but not yet passed are flagged as such.
- Prices: no public body publishes construction or renovation costs per m² in Luxembourg. Our ranges are therefore market surveys, dated and generally excluding VAT, checked against STATEC’s construction price index (+2.6% year on year in April 2026).
- Dates: every guide shows its last update date; only a signed quote binds a company.

How partner companies are chosen
Every partner company is established in Luxembourg and holds, for its trade, a business permit that can be checked on guichet.lu; renov.lu verifies it when the company joins the network and removes companies that generate disputes.
- One request, few companies: your project is forwarded to 3 companies covering your trade and area, which contact you within 48 working hours.
- Who pays: the partner companies, through a monthly subscription. Homeowners pay nothing and renov.lu takes no commission on the works: this is what allows it to publish independent price guides.
- Your freedom: you sign with the company of your choice, or with none.
To check any company yourself (permit, insurance, warning signs), follow our guide to choosing a renovation company. Are you a tradesperson in Luxembourg? See become a partner.
