How this renovation calculator works

This calculator estimates the cost of your renovation from the scope of the works and the items you select, in a few minutes and without registration.

The result is an indicative range designed to frame your budget before requesting quotes. Energy-related items, often the priority to improve a property's EPC score, deserve to be refined first in your project.

What a renovation cost calculation covers

A renovation cost calculation adds up each item of work, then weights the total according to the surface area involved and the scale of the intervention.

A refresh, a heavy renovation and bringing a home up to standard call on neither the same trades nor the same site durations. That difference pulls two budgets apart for an identical surface area.

The condition of the building does the rest, between site access, services to be redone and structure to be reinforced. An online estimate frames the project, before you request firm quotes.

Does the estimate include renovation subsidies?

This estimate shows your renovation budget before any subsidies, so you see the full cost up front. Regional grants and premiums can then reduce what you actually pay, depending on the works you plan and your situation.

Treat the result as your starting figure, then check which premiums fit your project before you commit.

FAQ

No. An online estimate frames a budget and compares scenarios. Only a signed quote commits a professional to a price and a deadline.
The surface area to renovate, the list of items involved and the current condition of the property are enough for a first order of magnitude.
In 2026, expect 400 to 800 EUR/m2 for light renovation, 800 to 1,500 EUR/m2 for medium, and 1,500 to 2,500 EUR/m2 for heavy renovation.
Each region offers subsidies: Habiter Mieux (Wallonia), Renolution (Brussels), and Mijn Verbouw Premium (Flanders). Amounts depend on the type of work and your income.
Structural work or change of use requires a building permit. Purely cosmetic interior renovations generally do not.
Tax benefits vary by region and type of work. Insulation and energy-saving work often qualifies for tax advantages.
Renovation is advantageous when purchase price + renovation stays below equivalent new-build price, and when the location is strategic. New builds offer guarantees and better EPC.
Yes. Start from the calculator's estimate, then subtract the grants you qualify for. Energy works such as insulation, heating or windows often unlock regional premiums, though eligibility depends on your situation. Confirm it with the official regional programme before you finalise your budget.
