The vert.lu directory classifies companies along two complementary axes: the trade practised and the locality served. Each company has its own profile bringing together its contact details, declared trades, service area and the publicly available information needed to make an informed contact. You can reach a profile from a trade page, from a city page, or directly from the full alphabetical company index.
This dual entry mirrors how homeowners actually search for a tradesperson: some already know which trade they need, while others prefer to start from a company near them and then check whether it covers the right trade. Both paths lead to the same profiles, so information never needs to be duplicated.
The most efficient search starts with the trade: heating, insulation, roofing, facades, joinery, electricity, masonry, plumbing, garden, or general services. Once the trade is set, narrow down by locality so you only see companies that genuinely operate in or near your municipality, since misjudging a service radius often means extra travel charges or longer waiting times.
The last step, availability, is not always visible on the profile itself: it is confirmed only once you make contact. That is why it helps to reach out to several companies matching the same trade and area rather than stopping at the first result. For urgent or seasonal projects, such as a heating breakdown in winter, favour companies whose profile explicitly mentions emergency call-outs.
A company profile brings together the registered name, address and municipality, contact details, declared trades and, where publicly available, the establishment authorisation matching the activity practised. This information comes from public sources or from the companies themselves; the page on data sources explains where it comes from and its limits.
The order in which results appear reflects how closely your search matches each company's declared trades and service area. This ranking is not a quality judgement: it does not reflect customer reviews or prices, since the directory does not publish either. It simply shows which companies best match the criteria entered.
The establishment authorisation (autorisation d'établissement) is the document issued by the Luxembourg administration that entitles a company to practise a regulated craft or commercial activity. For building trades, it certifies that the company meets the qualification and professional integrity requirements set by law. It is specific to the activity concerned: a company authorised for electrical work is not automatically authorised for plumbing.
Before signing anything, it is reasonable to ask the company to confirm its authorisation for the exact trade relevant to your project, and to check that the name and reference match the entity that will actually invoice the work. If in doubt, the competent authority can be contacted directly; do not rely solely on an unverifiable mention on a commercial website.
Four simple checks prevent most disputes seen in the building trade. First, professional liability insurance, which covers damage caused during the work. Second, a written, itemised quote covering materials, quantities, labour, timelines and payment terms: a verbal agreement protects no one. Third, the warranties applicable to the work, which vary by type of intervention and should be stated in writing rather than assumed.
Fourth, concrete references: comparable projects completed recently, provided the company is willing to share them. A serious company has no difficulty answering these four questions before work begins.
A generalist suits minor maintenance work, one-off interventions, or projects combining several simple trades without particular technical requirements. A specialist is called for as soon as a project involves a specific technology, a particular regulation, or expertise that determines the performance or safety of the installation: heat pumps, photovoltaics, EV charging points, or any work on an existing electrical installation.
If in doubt, ask the contacted company whether it subcontracts part of the job to a specialised trade. That is not a problem in itself, but you should know it before signing, since it affects contractual liability and the warranties that apply.
From a company profile or a trade page, you can describe your project in a few minutes and send your request to the companies in our directory matching the trade and area you are looking for. Available companies will contact you directly to arrange a visit or refine their quote. The service is free for homeowners and carries no obligation: you remain free to compare several proposals before choosing.
