The price per m² is the most reliable compass for scoping a renovation project. It is also the most abused figure: between a refresh and a complete energy renovation, the budget for the same house can more than quadruple. Here are the 2026 ranges observed in Belgium, with concrete examples to place your own project.
Price ranges in 2026 per m²
| Type of renovation | Price per m² |
|---|---|
| Light renovation (paint, floors, finishes) | €400 to €800 |
| Medium renovation (with technical systems: electrics, heating, plumbing) | €700 to €1,100 |
| Deep or complete energy renovation | €1,100 to €1,800 |
| Demolition and rebuild | €1,500 to €2,200 |
These ranges cover labour and materials for the whole site. Which VAT rate applies depends on your situation; we come back to it below.
The ranges overlap, and that is normal: a medium renovation in a sound house can cost less per m² than a light renovation in a degraded property where everything fights back.
What drives the price
- The initial state of the building. Damp, stability, a tired roof: the ailments of older buildings get paid for before you even think about decoration.
- The technical systems. Electrics to bring up to standard, heating to replace, plumbing to relocate: these are the items that push a project from one category to the next.
- The energy ambition. Full insulation, ventilation, heat pump: an energy renovation costs more upfront but part of it comes back through grants and lower energy bills.
- The level of finishes. Between entry-level and bespoke, the same site lives in a different world.
- The surface area. Large volumes dilute certain fixed costs: the price per m² of a large house is often gentler than that of a small flat.
- Access and region. A city centre with no parking or a terraced house with no side passage complicates logistics, and labour rates vary from region to region.
Worked examples
Three scenarios, calculated strictly from the ranges above:
- Refreshing a 100 m² flat (light renovation, €400 to €800/m²): €40,000 to €80,000.
- Renovating a 150 m² house including technical systems (medium renovation, €700 to €1,100/m²): €105,000 to €165,000.
- Deep energy renovation of a 150 m² house (€1,100 to €1,800/m²): €165,000 to €270,000.
For the same 150 m² house, demolition and rebuild (€1,500 to €2,200/m²) would represent €225,000 to €330,000. The gap with a deep renovation is not always as wide as you might think: when the building is badly degraded, have both options priced before deciding.
VAT and grants
Two levers reduce the real bill:
- The 6% VAT rate. Works on a private home over 10 years old qualify for the reduced rate of 6% instead of 21%, provided a BCE-registered contractor carries out the works and the invoice states the conditions. Details in our article on the 6% VAT rate in Belgium.
- Regional grants. In Brussels, see our guide to the Brussels grants for 2026. In Wallonia, a transitional scheme accepts applications until 30 September 2026, see our guide to the Walloon grants. In Flanders, the Mijn VerbouwPremie counter centralises the support.
In every case, check the official portal of your region before signing: conditions change.
Mistakes to avoid
- Renovating room by room with no overall plan. Repainting before pulling the new electrical cables means paying for the same wall twice. Fix the layout of the technical systems first.
- Starting without a contingency margin. In older buildings, surprises are the rule, not the exception. Build in a reserve from the start rather than negotiating under pressure mid-site.
- Comparing quotes that do not include the same items. Stripping out, waste removal, finishes: a cheaper quote is sometimes just a less complete one. Demand the detail item by item.
- Ignoring the logical order of works. Insulating after replacing the heating means an oversized boiler. Envelope first, systems second.
- Forgetting permits and the architect. Depending on the nature of the works and your region, a permit or an architect may be required: check with your municipality before starting, as the rules vary.
FAQ
What budget per m² to renovate a house in Belgium in 2026?
Allow €400 to €800/m² for a light renovation, €700 to €1,100/m² as soon as technical systems are involved, and €1,100 to €1,800/m² for a deep or complete energy renovation.
Is it better to renovate or to demolish and rebuild?
Demolition and rebuild sits at €1,500 to €2,200/m², against €1,100 to €1,800/m² for a deep renovation. With a sound structure, renovation keeps the advantage. When the building stacks up problems, rebuilding can become competitive: have both scenarios priced.
Do I need an architect to renovate?
Often yes, as soon as the structure or the envelope of the building changes or a permit is required. The precise rules vary by region and by type of works: check with your municipality before committing.
