How much does a renovation cost in Luxembourg?
Useful ranges: a refresh usually costs €400 to €800 per square metre; a mid-level renovation with kitchen, bathroom and electrics €800 to €1,200; a deep renovation often exceeds €1,200.
The drivers are demolition volume, electrical compliance, pipework and finish level. A 1970s home never renovated almost always hides surprises.
Keep a contingency of 10% to 15% of the budget.
What grants exist for renovation?
Two levers: the 3% housing VAT rate with a tax advantage capped at €50,000 per dwelling, and the Klimabonus programme for energy improvements.
They often combine. Binding amounts are published by the state on guichet.public.lu.
In which order should work be done?
Structure and roof first, then envelope and external joinery, then services and heating, finishes last. Reversing that order means doing work twice.
If the budget is tight, start with what durably cuts consumption: roof insulation, the worst windows, heating controls.

Frequently asked questions
Renovation in Luxembourg: your questions
What is the average renovation price in Luxembourg?
A refresh is often €400 to €800 per square metre, a mid-level renovation €800 to €1,200, a deep renovation above €1,200. Only a quote after a site visit is binding.
Which grants can I claim?
The 3% housing VAT rate, capped at a €50,000 advantage per dwelling, and Klimabonus grants for energy work. Official amounts are on guichet.public.lu.
Do I need a municipal permit?
It depends on the work. Changes to the façade, roof, volume or use generally require authorisation. Check with your commune first.
How long does a full renovation take?
Six to twelve months for a fully renovated house, four to eight weeks for an apartment refresh.
Can I stay in the home during the work?
For a refresh, often yes. Once water, electricity or structure are involved, temporary relocation is more realistic.
Are the quotes free?
Yes, free and with no obligation for homeowners.
