Renovation Works in Luxembourg:
Complete Guide 2026
From project preparation to handover: timelines, budgets, choosing professionals and financial grants. More than 60% of Luxembourg homes were built before modern standards — renovating means better comfort, 50–80% lower bills and +10 to +20% property value.
Types of renovation in Luxembourg
There are three main types of renovation in the Grand Duchy, each with different objectives, budgets and timelines.
🏠 Interior renovation
- Timeline: 2 to 8 weeks
- Budget: €5,000 – €60,000
- Kitchen, bathroom, flooring, painting
- Ideal for refreshing an existing home
- 3% VAT applicable on labour
⚡ Energy renovation
- Timeline: 4 to 16 weeks
- Budget: €20,000 – €180,000
- Insulation, heat pump, ventilation, windows
- Energy bill savings of 50–80%
- Klimabonus grants up to 62.5% of costs
Projects combining interior and energy renovation in a single intervention: allow 3 to 6 months for a 100–150 m² home. Often the most cost-effective approach — fewer interventions, better cohesion, and the ability to maximise cumulative grants (Klimabonus + 3% VAT + Enoprimes).
Partial or full renovation in Luxembourg: which level to choose?
As of July 2026 in Luxembourg, three renovation levels coexist: light refurbishment (€250–750/m², 1 to 3 weeks), partial renovation — 1 to 3 rooms or a single trade — at €750–1,250/m² on the treated area, and full renovation at €1,150–2,500/m² over 3 to 6 months. With most of the country’s houses dating from 1950–1980, the practical rule is simple: systems under 20–25 years old, a partial renovation is enough; a pre-1980 property never renovated calls for a full one.
| Criterion | Partial renovation | Full renovation |
|---|---|---|
| Budget | €750 – 1,250/m² (treated area) | €1,150 – 2,500/m² (entire surface) |
| Duration | 2 to 8 weeks | 3 to 6 months |
| Trades involved | 1 to 2 specialists | 4 to 8, coordinated |
| Home stays liveable | Yes, generally | Difficult — temporary housing €2,000–3,000/month |
| Property value gain | +5 to +10% | +10 to +20% |
| Contingency to budget | 5 to 10% | 10 to 20% |
| Lifespan of the result | 10 – 15 years | 20 – 30 years |
Before a resale, kitchen (ROI 80–140%) and bathroom (90–110%) remain the safest bets. The 3% VAT applies to both levels (dwelling over 10 years old, main residence), but only a full renovation with an energy component unlocks Klimabonus and Enoprimes: €40,000 to €80,000 in aid on €200,000 of works — applications must be filed before signing the quote.

How to prepare your renovation project in Luxembourg?
A well-prepared project is a project delivered on time, on budget, with no nasty surprises. Here are the three key steps.
Define the scope and your budget
Clearly identify the area to renovate (room, floor, façade), the goal (comfort, energy savings, resale value), the desired materials and a realistic budget. Check our renovation cost per m² to calibrate your envelope. Also decide between a partial or full renovation — this choice shapes everything that follows.
Request quotes and check permits
With a clear description, budget and measurements, Luxembourg contractors can quote quickly. They will carry out a free technical site visit. Remember: some works require a building permit or prior declaration from your municipality.

To refresh and beautify
If your goal is to give your home an instant visual lift, here are the works with the best immediate impact:
Renovate the bathroom
Walk-in shower, modern tiling, wall-hung vanity unit: a renovated bathroom transforms how a property is perceived. Average budget: €8,000 to €20,000. See bathroom renovation costs.
Renovate the kitchen
Open kitchen, quartz worktop, integrated appliances: kitchen renovation is one of the best investments in terms of return. Average budget: €10,000 to €25,000.
Flooring and painting
XXL vinyl planks, solid wood, or large-format tiles: new floors change everything. Pair with white paint on all walls and your home will feel twice as spacious. See our flooring comparison guide.
Convert the attic
Lost attic, basement, garage: these unused spaces often represent 15–30% of your total floor area. Converting them creates living space at a fraction of the cost of an extension.
To maximise value and savings
These renovations have the best ROI and benefit from Luxembourg’s most generous grants:
External wall insulation (ETI)
Exterior insulation is the top priority for unrenovated homes. It eliminates 15–25% of heat loss and can receive Klimabonus up to €115/m². Combine with roof insulation for 25–30% further gains.
Heat pump (boiler replacement)
An air-to-water heat pump cuts heating bills by 30–50% and can receive grants up to €9,500 (Klimabonus + Enoprimes). See heat pump prices and grants.
Triple glazing windows
Windows account for 10–15% of heat loss. Triple glazing improves both thermal and acoustic comfort, with Klimabonus grants of €70/m² of glazing. Combine with a dual-flow VMC for optimal results.
Solar photovoltaic panels
For homes with a heat pump, the HP + PV combination is the most profitable strategy. A 6 kWp system produces 5,400–6,000 kWh/year in Luxembourg. Discover solar panel grants.
Which flooring to choose in Luxembourg? Installed prices and lifespan
As of July 2026 in Luxembourg, installed prices (incl. VAT) range from €40–90/m² for LVT vinyl to €100–400/m² for natural stone. Tiles (€30–150/m², 20–40 year lifespan) and engineered parquet (€65–150/m², 15–25 years) offer the best durability-to-price ratios.
| Flooring | Installed price (incl. VAT) | Lifespan | Maintenance |
|---|---|---|---|
| Solid parquet | €100 – 330/m² | 20 – 30 years | High |
| Engineered parquet | €65 – 150/m² | 15 – 25 years | Medium |
| Laminate | €40 – 120/m² | 10 – 15 years | Minimal |
| Tiles | €30 – 150/m² | 20 – 40 years | Minimal |
| LVT vinyl | €40 – 90/m² | 10 – 15 years | Minimal |
| Natural stone | €100 – 400/m² | 30 – 50+ years | High |
| Polished / waxed concrete | €80 – 230/m² | 15 – 25 years | Medium |
| Cork | €50 – 120/m² | 12 – 20 years | Medium |
Choose room by room: tiles or LVT in kitchens and bathrooms (slip-resistance class R10+ in wet areas), engineered parquet or laminate in living rooms, parquet or cork in bedrooms for acoustics. Budget grid: €30–60/m² (laminate, LVT), €60–150/m² (engineered parquet, tiles), €150/m² and up (stone, solid wood, waxed concrete). For a main-residence renovation, installation qualifies for the 3% VAT.

How to choose the right professionals in Luxembourg?
The success of your project depends above all on the contractors you hire. In Luxembourg, where standards are high, here are the essential criteria.
Check certifications and registration
Make sure the company is registered in the Luxembourg Trade Register. For energy renovations, verify Klimabonus approval (mandatory to receive grants). « Made in Luxembourg » labels guarantee local expertise and knowledge of national regulations.
Require experience and references
Favour companies with at least 15–20 years of experience in Luxembourg. Ask for photos of recent similar projects, client testimonials and direct reference contacts. A quality contractor will readily connect you with former clients.
Check insurance and guarantees
Professional liability insurance: mandatory. Ten-year structural warranty: essential. One-year completion guarantee: indispensable. Without these, you’re exposed in case of defects. See our guide on how to compare renovation quotes.
Compare at least 3 quotes
Never choose based on a single quote. Three quotes let you spot abnormally low prices (a sign of cash-in-hand work or poor materials) and overcharging. Also look at the clarity of the description, guaranteed timelines and payment terms.
Renov.lu has selected certified, experienced and insured contractors in Luxembourg. Requesting a quote on our platform gives you up to 3 proposals from verified, Klimabonus-approved companies, including a free technical site visit. See also our directory of renovation companies in Luxembourg.

Renovating a rental building in Luxembourg: rent cap, VAT and taxation
As of July 2026 in Luxembourg, renovating a rental building mechanically raises the legally permitted rent: annual rent is capped at 5% of the invested capital (law of 21 September 2006, amended 1 August 2024), and that capital includes both the purchase price and investment works — so every €50,000 of works adds €2,500/year to the legal cap.
| Investor lever | Mechanism | Key figure |
|---|---|---|
| 5% rent cap | Annual rent ≤ 5% of invested capital (acquisition + investment works) | +€50,000 invested = +€2,500/year of permitted rent |
| 3% VAT per dwelling | €50,000 tax-advantage cap per dwelling; building at least 20 years old; AED approval before the first invoice | 4 dwellings = up to €200,000 of tax advantage |
| Accelerated depreciation | 6% per year for 10 years on Klimabonus energy works (vs 2% under the ordinary regime) | €100,000 of works = €6,000/year deductible |
Add mortgage interest deductible without any ceiling and a rental deficit offsettable against all taxable income. After renovation, expect a gross yield of 4.5–5% in Esch-sur-Alzette and 3.5–4% in Luxembourg City. Full conditions on our 3% VAT renovation page.

Benefits of renovating in Luxembourg
Give your home a fresh look
Kitchen, bathroom, flooring, paint: a property needs maintenance and renovation every 5 to 10 years to maintain its appeal. A well-planned refresh with the right materials can radically transform your living experience. See our guide on renovation costs and trends.
Improve energy efficiency and cut bills
This is the #1 value driver in Luxembourg in 2026. Works eligible for Klimabonus deliver:
- Wall, roof and floor insulation → 25–55% reduction in heating bills
- Boiler replacement with heat pump → additional 30–50% reduction
- Energy passport improvement → jump from class G to C or B
- PV panels + heat pump → near-zero electricity bill in summer
A class A home uses up to 5 times less energy than a class G home. At €0.258/kWh in 2026, annual savings can exceed €2,000/year for a 130 m² house.
Increase your property’s market value
In the Luxembourg real estate market, renovation offers strong returns:
- Interior renovation (kitchen + bathroom + flooring): +5% to +10% on sale price
- Major energy renovation (class E → class B): +10% to +20% on sale price
- Extension or attic conversion: value proportional to the new floor area created
Luxembourg is on a path to phase out « energy sieves » (F and G class) from its rental market, following France and Belgium. Renovating now means anticipating imminent regulations and protecting your property’s rental value. See our guide on the energy passport’s impact on property prices.

Frequently asked questions about renovation in Luxembourg
What are the different types of renovation in Luxembourg?
Three main types: interior renovation (kitchen, bathroom, flooring — 2 to 8 weeks), energy renovation (insulation, heat pump, ventilation — with Klimabonus up to 62.5%) and full renovation (everything included — 3 to 6 months). Full renovation is often the most cost-effective as it allows all available grants to be combined.
What grants are available for renovation in Luxembourg in 2026?
Several cumulative schemes: 3% VAT (on all works on primary residences >10 years, cap €50,000), Klimabonus (up to 62.5% of insulation costs and €9,500 for a heat pump), Enoprimes (~€1,500), municipal grants (€1,500–€3,000) and the Klimaprêt (up to €100,000 at a reduced rate). See our renovation grants guide 2026.
What is the average cost of a full renovation in Luxembourg?
For a 120 m² house: between €24,000 (partial renovation) and €180,000 (full renovation including energy works). The cost per m² ranges from €150/m² (flooring only) to €1,500/m² (full high-end renovation). Use our simulator for a personalised estimate.
Does renovation in Luxembourg require a building permit?
It depends on the works. Simple interior renovation (paint, tiling, kitchen, bathroom) generally requires no permit. However, any modification to load-bearing structures, façades, roofing or creation of new floor area (attic, extension) requires a permit or prior declaration. Check with your municipality or see our guide on building permits in Luxembourg.
Which renovation offers the best ROI in Luxembourg?
Combined energy and interior renovation is the best ROI strategy. It increases property value by 10–20%, cuts running costs by 50–80% and benefits from grants covering up to 62.5% of works. In the short term, bathroom and kitchen renovation offer the best impact/cost ratio for resale or rental. See our analysis on the link between energy class and property value.
