Renovation Budget Luxembourg 2026: How to Estimate Your Works Cost
Estimating a renovation budget in Luxembourg means mastering five key variables: the scope of works (light, partial or complete), the surface area, the condition of the property, often-forgotten costs and available financial aid. In Luxembourg, classic renovation prices range from €250/m² to €2,500/m² depending on the project’s ambition, with labour costs among the highest in Europe. This practical guide gives you the concrete tools to build a realistic, item-by-item estimate and avoid bad surprises.

Before estimating anything, the first decision is to qualify the renovation level of your project. This level directly determines the budget scale and the trades involved. Three well-established categories exist in Luxembourg:
1. Light renovation (refresh) — €250 to €750/m²
Light renovation covers purely aesthetic and decorative works: interior painting, replacement of soft floor coverings (vinyl, carpet, laminate flooring), wallpaper, replacing a few lights or handles. Networks (electricity, plumbing) are not touched, the structure is preserved. This type of renovation is possible in an occupied property, with tradespeople working room by room.
2. Partial renovation — €750 to €1,250/m²
Partial renovation works on technical installations and may require partial redistribution of spaces. It typically includes: bathroom or kitchen renovation (plumbing, tiling, fittings, joinery), replacement of the heating system, partial electrical compliance, replacement of windows or interior doors. Load-bearing walls are not touched.
3. Full renovation (heavy works) — €1,150 to €2,500/m²
Full renovation affects the entire property: demolition and redistribution of partitions, complete overhaul of electrical and plumbing networks, insulation, complete replacement of joinery, new heating, new kitchens and bathrooms, complete finishes. It is essential for a property purchased empty to renovate, a house from before 1980 never refurbished, or an extension project.
The 5-step method to estimate your renovation project
A renovation budget is not a simple multiplication of surface × price per m². It is built in a funnel, from general to specific. Here is the method used by Luxembourg professionals:
Define the precise scope of works
Write a list of each room concerned and each desired intervention. For each room, specify whether you are touching the walls (demolition/partition), floor (type of covering), ceiling, technical equipment (sockets, radiators, taps) or joinery (doors/windows). This list forms the project brief you will give to tradespeople to obtain comparable quotes.
Measure the surfaces involved
Precisely measure the surfaces concerned by each type of work: floor area for coverings, linear metres for wall painting (perimeter × ceiling height, deduct openings), false ceiling areas, number of water points, number of electrical circuits.
Identify the property’s condition and technical constraints
The existing condition is the most underestimated factor. A property built before 1980 may contain asbestos (removal cost: €5,000–€30,000), non-compliant electrical installations (compliance: €8,000–€20,000), or structural moisture problems (treatment: €3,000–€8,000).
Obtain at least 3 comparable quotes
With your brief and measurements, contact three tradespeople or general contractors for each work package. Require detailed quotes with labour separated from materials, material references, applicable VAT rate (3% or 17%), and execution timeline.
Integrate grants and calculate the net budget
Identify applicable grants: 3% VAT (saving of 14% on the ex-VAT amount up to the €50,000 fiscal benefit cap), and possibly Klimabonus if insulation or heating works are included. Add the contingency margin to arrive at a realistic total.
Item-by-item budget breakdown for renovation in Luxembourg
A renovation budget is structured into major work categories. Here are the reference ranges in Luxembourg, verified on the local market (June 2026):
Demolition and clearance
Often underestimated, demolition can represent 5–10% of the total budget. Count €15–40/m² for light interior demolition (plasterboard partitions), and €50–120/m² for masonry demolition. Rubble removal is often billed separately: €300–800 for a 70 m² apartment.
Structure and masonry
Creating or removing partitions: €80–180/m². Opening in a load-bearing wall with IPN beam: €2,500–8,000. Floor screed: €15–30/m².
Electrical
Partial compliance (panel + a few circuits): €2,000–5,000. Complete rewiring of a 70 m² apartment: €8,000–20,000. Electricians charge €45–65/hour in Luxembourg.
Plumbing and heating
Hot water tank replacement: €800–2,000. Complete plumbing for a 70 m² apartment: €6,000–15,000. Replacement of a gas boiler by an air/water heat pump: €12,000–20,000 before grants. Plumbers charge €50–70/hour.
Floor coverings
Tiling including fitting (mid-range): €60–120/m². Solid wood parquet including fitting: €80–180/m². Luxury vinyl tile (LVT): €35–65/m².
Kitchen and bathroom
Complete kitchen (units, worktop, appliances, installation): €8,000–70,000. Complete bathroom: €6,000–30,000.
Painting and finishes
Professional painting of walls and ceiling: €20–45/m² of painted surface. Joiner (doors, parquet, panelling): €55–80/hour.

Most renovation budget overruns come not from rising prices of visible works, but from peripheral items systematically omitted in the initial estimate.
Asbestos removal (€5,000–€30,000)
Many properties built before the 1990s contain asbestos in floor tiles, adhesives, false ceilings, pipes or facade plaster. If discovered during works, the site must stop and regulated removal must be organised.
Unplanned electrical compliance (€8,000–€20,000)
When plumbing or structural works require moving walls, existing electrical installations can prove non-compliant with current standards. Full compliance for an 80 m² apartment typically costs €8,000–20,000.
Moisture treatment (€3,000–€8,000)
Rising damp, facade infiltration or roof waterproofing issues are often discovered once works begin and walls are opened.
Floor screed (€15–30/m²)
After removing old tiles or flooring, the bare concrete is rarely ready for a new covering. Self-levelling screed is almost always required.
Tradesperson travel costs
In Luxembourg, some tradespeople charge travel costs, particularly for sites outside their main area. These fees, rarely mentioned in quotes, can represent €50–200 per visit.
Administrative and permit fees
If works require a building permit, include architect fees if the amount exceeds €6,197.34 ex-VAT (Luxembourg legal threshold), plus municipal filing fees. An architect’s permit file typically costs €2,000–8,000.
Temporary accommodation during works
In Luxembourg, renting a furnished transition apartment costs €1,800–3,500/month. For a 3-month project, this represents €5,000–10,000 never included in tradesperson quotes.
End-of-site cleaning and small finishes
A building site always generates small unplanned finishing works: filling cable chases, paint touch-ups, professional end-of-site cleaning (€300–800). These can cumulatively represent €1,500–4,000 on a large project.
3% VAT: how to legally reduce your renovation budget
The super-reduced 3% VAT is one of the most significant tax measures for renovation in Luxembourg. Used correctly, it can represent a saving of 14 VAT points (17% − 3%) on the total works amount, up to a €50,000 fiscal benefit per property.
Eligibility conditions (source: guichet.public.lu)
1. Primary residence use: The property must be used as a primary residence — directly by the owner, or indirectly as a rental (renovation works only).
2. Building at least 10 years old: The building permit must have been issued at least 10 years ago.
3. Prior AED approval: The tradesperson must obtain approval from the AED before works begin. Without this, they invoice at 17% and you must request a refund.
4. €50,000 fiscal benefit cap: This represents the maximum VAT saving per property over its entire fiscal lifetime. You can check the remaining balance via MyGuichet.lu.
Works ex-VAT = €80,000 → VAT at 17% = €13,600 → Normal total = €93,600
With 3% VAT (within cap) = €80,000 × 0.03 = €2,400
Saving = €11,200 on the total invoice
Financing your renovation in Luxembourg: loans and available grants
Financing a classic renovation in Luxembourg rests mainly on three pillars: personal savings, bank renovation loans, and fiscal incentives (3% VAT). For projects with an energy dimension, additional schemes apply.
Classic renovation loan
For classic renovation (without energy criteria), the standard financing solution is a personal loan or consumer credit for works from Luxembourg banks. Plan a personal contribution of at least 20–30% of the total budget.
The Klimaprêt (for energy-related works)
If your project includes insulation, heating, ventilation or photovoltaic works, you are eligible for the Klimaprêt:
- Maximum amount: €100,000 per property
- Maximum term: 15 years
- Interest subsidy: 1.5% covered by the State, capped at 10% of the borrowed capital (maximum €10,000)
- Combinable with Klimabonus and 3% VAT
3 detailed budget examples in Luxembourg (June 2026)
These examples are based on Luxembourg market rates, include labour, materials and 3% VAT where applicable. They exclude contingency (add per next section).
Example 1 — Light renovation of a 55 m² apartment
Objective: full refresh before rental. 1985 apartment, 3 rooms, good general condition, services not affected. Estimated total with 15% contingency: ~€14,000.
Example 2 — Partial renovation of a 110 m² house (Luxembourg-City)
Objective: kitchen and 2 bathrooms, windows, full painting. 1978 house, eligible for 3% VAT. Estimated total with 15% contingency: ~€90,000.
Example 3 — Full renovation of a 130 m² house (1975 build)
Objective: complete overhaul for family occupation. Purchase to renovate, brick house, medium condition. Estimated net budget after grants: ~€180,000.
The contingency margin rule: how much to set aside in Luxembourg?
The contingency margin is the most important budget line in a renovation and the most often underestimated or ignored.
| Project type | Recommended margin | Justification |
|---|---|---|
| Light renovation, recent property (post-1995) | 10% | Few surprises possible, superficial works |
| Partial renovation, 1980–1995 property | 15% | Moderate risk: electricity, plumbing, possible asbestos |
| Full renovation, 1960–1980 property | 20% | Probable asbestos, moisture, unknown structure |
| Full renovation, pre-1960 property | 25–30% | High structural risks, possible lead, foundations |
5 classic mistakes that blow renovation budgets in Luxembourg
Mistake 1: Estimating from a single quote
In Luxembourg, differences between tradespeople can be threefold for the same service. Always compare at least 3 quotes — not just on the total price, but on the detail of each item.
Mistake 2: Not locking prices before starting
A quote in Luxembourg is valid for 30–90 days. Once you’ve made your choice, validate the quote in writing and confirm the start date immediately.
Mistake 3: Overestimating financial grants
Build your budget without grants, then deduct them as a bonus. The Klimabonus only applies to energy works; 3% VAT requires the building to be at least 10 years old; grant payment timelines can take several months.
Mistake 4: Using tradespeople not established in Luxembourg
Non-Luxembourg tradespeople cannot legally apply 3% VAT on their invoice and are not covered by Luxembourg professional guarantees. The apparent saving can become a fiscal and legal liability.
Mistake 5: Starting works before obtaining permits
Starting a site requiring a building permit without prior authorisation exposes you to immediate site stoppage, demolition orders, and insurance refusal. Always check permit requirements with your commune before signing any quote.

For a light renovation (painting, floors, a few replacements), count €12,000–20,000 for a 60 m² apartment in generally good condition. For a partial renovation with refurbished bathroom and kitchen, the budget rises to €35,000–60,000. A full renovation of 60 m² in Luxembourg-City can reach €80,000–120,000.
No. 3% VAT is not automatic. It requires the tradesperson to obtain AED approval before works begin. The building must be at least 10 years old, works must concern the primary residence, and the total fiscal benefit cannot exceed €50,000 per property.
Plan at least 6 months ahead for a partial renovation, and 12 months for a full renovation. Qualified tradespeople in Luxembourg often have a 3–6 month waiting list.
Yes. Both devices are distinct and combinable for works eligible to both programmes (insulation, windows, heat pump). 3% VAT is managed by the AED and applied on the tradesperson’s invoice; Klimabonus is managed by the Klima-Agence and paid directly to the owner after works completion.
An estimate is a global projection established before contacting tradespeople, based on average prices per m². A quote is a contractual document established by a tradesperson after site visit, detailing services and prices item by item. Only a signed quote has contractual value.
