Reviewed each quarter
Four times a year we compare the full price database against current Belgian market sources, and in between when there are large swings.
Transparency
How up to date are our prices?
Renovation prices move. We openly explain how often and in what way we recalibrate our database, and show with an index how the figures have evolved since the baseline.
Prices last verified: April 2026
How we keep prices current
We work to a fixed rhythm and a documented procedure, so an update never depends on chance or memory.
Fixed procedure
Every recalibration follows a fixed step plan with traceable sources — no loose, undocumented adjustments.
Verified before publishing
We always show a last-verified date, so you know how fresh the figures behind your estimate are.
Price index since the baseline
To make the evolution visible without exposing our price database, we show a composite index with base 100 at the first verification. 103 means on average +3% since the baseline.
| Period | Type | Index | Since baseline |
|---|---|---|---|
| April 2026 | PricesTransparency.history.kind.baseline | 100 | — |
This is the baseline. The evolution curve fills in automatically from the next quarterly recalibration — we'd rather show one honest starting point than an invented chart.
We deliberately show an index, not euro amounts or per-category factors. How we combine prices, labour and execution into an estimate stays our calculation model — the index shows the trend without exposing that model.
Which sources do we rely on?
Our prices rely on 5 recognised Belgian market and trade sources. The full list, with links and what we do with each source, is on our methodology page.
