Trades in Luxembourg

Luxembourg sits in the canton of Luxembourg (postcode L-1000), close to Hesperange, Strassen, Bertrange, Walferdange, Sandweiler, Niederanven. The Vert.lu directory lists trades and installers there for solar, heating, insulation, roofing, electrical work and other trades, compiled from public sources (trade register, Chambre des Métiers) and information submitted by the companies themselves.

For work on a building in Luxembourg, a company based in the commune or in a neighbouring locality is often the most practical choice: shorter travel, a more realistic schedule, and someone who stays reachable if a follow-up visit is needed later.

Any company carrying out trade work in Luxembourg must hold an autorisation d'établissement and be registered with the Chambre des Métiers or the Chambre de Commerce. Always ask for a detailed quote that separates materials, labour and ancillary costs, and compare several proposals before signing. Depending on the project, Klimabonus funding or the reduced 3% "TVA logement" VAT rate may apply; applications go through MyGuichet.lu and the Administration de l'enregistrement, des domaines et de la TVA respectively.

Requesting a quote through Vert.lu is free and without obligation. Vert.lu is a directory, not a contractor: the contract and the execution of the work rest solely with the company you choose.

Trades and installers in Luxembourg City: renovation and home maintenance

The municipality and its housing stock

Luxembourg City is the country's capital and economic centre. Its building stock is very mixed: historic districts in the old town with older buildings, town houses and some listed façades, residential areas such as Belair, Limpertsberg or Merl with detached houses and small apartment buildings from various periods, and more recent development areas such as Kirchberg or Cloche d'Or with new construction and higher energy standards.

This diversity means renovation needs vary widely: electrical and heating upgrades in older buildings, roof and wall insulation in houses built from the sixties to the eighties, interior fit-out in newer homes. Co-ownership buildings are common, which often means several owners need to coordinate on works affecting shared areas such as the roof or façade.

Urban density and access or parking constraints are practical factors to plan for larger projects such as roof renovation or an extension in Luxembourg City.

The capital's property market remains very active, which pushes many owners to renovate rather than move, particularly to adapt an older home to current uses such as an open kitchen, an extra bathroom or a home office. This dynamic keeps demand steady for qualified tradespeople across almost every trade.

Needs by type of home

A town house in the city centre often needs a full overhaul of electrical and plumbing networks, sometimes work on floors or interior plastering, while preserving protected façade elements. A detached house in a residential district is more likely to need roof insulation, a boiler replacement or a refresh of an ageing bathroom. A newer apartment in Kirchberg or Cloche d'Or tends to need mainly finishing work, a new kitchen or fitting out a home office, since the structure and insulation already meet current standards.

Coordinating in a co-owned building

In an apartment building with co-ownership, work on shared areas, the roof, façade, lift or main pipework, is usually decided collectively at the owners' general meeting, coordinated by the managing agent overseeing the chosen company. An owner wanting to move an insulation or façade project forward should find out early about the schedule of general meetings, prepare comparable quotes to present to other co-owners, and check whether national energy-renovation grants apply to this kind of collective decision.

The most requested trades

In the older districts of the city centre, requests often concern electricity, plumbing and heating, frequently tied to bringing ageing installations up to standard. Replacing exterior joinery, especially windows, is also common in pre-war or mid-century buildings.

In residential areas with detached houses, roof and wall insulation and replacing heating systems with more efficient solutions such as heat pumps are common projects, often aimed at improving the home's energy passport.

In apartment buildings and co-ownerships, requests also cover roof maintenance, waterproofing and façade work. Interior projects such as kitchens or bathrooms are frequent in both newer homes and renovated older properties.

The mix of nationalities and lifestyles living in Luxembourg City also shapes the type of work requested, with growing attention paid to energy performance when buying or renting a property, as the energy passport becomes a selection criterion for many households.

Organising a project in the city

Parking and access are worth planning ahead of a project in Luxembourg City: delivering materials, placing a skip for rubble, or parking the tradesperson's vehicle. Depending on the district, a temporary permit for using the street may be required from the communal services, particularly in the narrow streets of the city centre or old town. It is worth clarifying this early with the chosen company, which is usually familiar with these procedures in the city.

Living close to neighbours, whether in a terraced house or an apartment building, also means giving advance notice of noisy work such as demolition or floor renovation, and agreeing reasonable working hours with the tradesperson. Good communication with neighbours beforehand often avoids unnecessary tension during the works.

What a written quote should include

Before confirming a project, a proper quote should state the exact nature of the works, the materials planned with their references, the estimated duration of the site, payment terms including any deposits, and the warranty conditions on the completed work. It is also useful for it to mention how site waste will be handled and who is responsible in case of damage during the works. Comparing several quotes on this same basis makes for a more informed decision than comparing only a total price.

Planning around the season

Some work suits certain times of year better: roof renovation or façade work is easier to carry out in spring or summer, outside frost or heavy rain periods, while interior work such as a kitchen, bathroom or electrics can be organised year-round. Replacing a heating system is best planned before autumn, to avoid being left without heating during the cold season and to benefit from often shorter lead times outside peak demand.

Local grants and procedures

Several national schemes can reduce the cost of a renovation project, wherever you are: the Klimabonus Wunnen, which replaced the former PRIMe House programme in 2022, for energy-related and renewable heating works and for the building's energy performance, and the 3 % housing VAT rate for certain works under conditions. Amounts and criteria change regularly and should be checked on guichet.lu, myenergy.lu or klima-agence.lu.

The City of Luxembourg may offer additional, municipality-specific support. Check directly with the communal administration and the official vdl.lu website for current conditions and procedures.

Certain works require a communal permit before starting, such as façade changes, roof replacement, installing a fence, or an extension. This applies particularly to buildings in protected or listed areas, of which there are many in the historic city centre. It is advisable to check this with the city's urban planning department before starting work.

Finding a company near Luxembourg with vert.lu

On vert.lu, you describe your project in a few minutes: type of work, property concerned, desired timeline. This single request is forwarded to authorised craft companies active in the Luxembourg City area that match the trade you need.

You then receive quotes directly from interested companies and compare them freely, with no obligation. The service is free for homeowners: vert.lu connects you with companies but does not carry out any work itself and charges the requester nothing.

This approach avoids contacting each company individually and saves time, especially in a city where demand for craft work is high and lead times can be longer than elsewhere in the country.
