How much does a total renovation cost in Belgium in 2026?

Undertaking a complete renovation in Belgium is a major strategic investment, both for living comfort and property value appreciation. In 2026, the construction market is characterized by increasingly strict energy standards and stabilized but high material costs.

This detailed guide presents realistic budgets, essential expenditure items, and the variables that will influence the final bill for your turnkey renovation project.

1. Estimated average price per m² in 2026

The cost of a total renovation varies mainly according to the scale of the structural work and the desired level of finish. In Belgium, for a "turnkey" renovation (including demolition, technical installations, and finishes), the following price ranges serve as a reference for 2026:

Type of renovation Description Average price per m² (excl. VAT)
Standard / Eco Complete refreshment, electricity, simple plumbing, standard materials. 1,200 € – 1,500 €
Comfort / Mid-range Advanced insulation, spatial reorganization, quality kitchen and sanitary facilities. 1,600 € – 2,100 €
High-end / Premium Heavy structural changes, home automation, noble materials (stone, solid parquet). 2,200 € – 3,000 €+

These prices generally include labor and materials but exclude architect fees and VAT (6% for homes older than 10 years, 21% in other cases).

2. Global budget by property type

Each type of dwelling presents specific technical challenges that impact the overall budget.

Apartment (80 - 100 m²)

Renovating an apartment often involves logistical constraints (elevator, co-ownership schedules). For a total renovation of a 90 m² apartment in Bruxelles, expect between 110,000 € and 160,000 € excl. VAT. The cost is often higher per m² than for a house because the technical areas (kitchen/bathroom) represent a larger share of the total surface.

Terraced house / Townhouse (120 - 180 m²)

This is the typical project in Belgium. The renovation often includes the roof and insulation of the rear facade. For 150 m², plan for a budget between 220,000 € and 320,000 € excl. VAT. Site access (narrow facade) can influence the cost of debris removal.

Detached house / Villa (200 m²+)

Here, the insulation surfaces (roof and walls) are significant. A total renovation for 200 m² oscillates between 350,000 € and 500,000 € excl. VAT. The integration of high-performance heating systems (heat pump, underfloor heating) is now the standard.

3. Breakdown of expenditure items (turnkey)

A total renovation with a general contractor like CULA covers all trades. Here is how the budget is generally distributed:

4. Influencing factors and regional disparities

The price of a renovation is not uniform across the Belgian territory.

  1. The Region: Bruxelles remains the most expensive area due to the complexity of urban planning permits, labor costs, and parking/logistics difficulties. Wallonie offers slightly more competitive labor rates, while Flanders imposes stricter energy standards (EPC standards), requiring heavier investments in insulation from the time of purchase.
  2. Initial condition: A healthy but outdated house will cost 30% less to renovate than a building suffering from rising damp or structural foundation problems.
  3. Technological choices: Switching to "all-electric" (heat pump, thermodynamic boiler) represents an initial surcharge of 15,000 € to 25,000 € compared to classic systems, but offers long-term profitability and an improved PEB label.

5. Concrete examples of renovation projects

Case study 1: The Brussels apartment (100 m²)

Case study 2: The single-family home (150 m²)

6. "Hidden" costs not to be overlooked

When planning your budget, always allow a safety margin of 10 to 15% for contingencies (discovery of dry rot, instability of a lintel, etc.). Don't forget to include:

7. Maximizing grants and financial aid

In 2026, grant systems (Primes Habitation in Wallonie, Renolution in Bruxelles, Mijn VerbouwPremie in Flanders) remains important levers. A major energy renovation can allow for a recovery of between 10,000 € and 40,000 € depending on your income and the energy performance improvement achieved. Using a certified general contractor often facilitates obtaining these aids through structured and compliant invoices.

FAQ: Frequently Asked Questions

Is it cheaper to renovate or rebuild in 2026? Renovation often benefits from a reduced VAT rate of 6%, which is a major advantage. However, if structural problems are too severe, demolition-reconstruction may prove more cost-effective in the long term to achieve passive house standards.

How long does a total renovation take? For a complete house, allow 6 to 10 months of actual work, excluding the design phase and obtaining permits (an additional 3 to 9 months).

Can I save money by doing the work myself? You can save on labor for demolition or finishes (painting). However, for techniques (electricity, plumbing) and insulation, professional expertise is indispensable to guarantee safety, insurance, and access to grants.

Conclusion

The cost of a total renovation in Belgium in 2026 averages between 1,500 € and 2,500 € per m². Although this amount represents significant capital, the increase in your property's value and the generated energy savings ensure a sustainable return on investment.
