Centria vs Cenogram: which Polish property-price data service to use
Centria and Cenogram both pull from the same public Register of Real Estate Prices (RCN) — so the raw transaction data itself isn't the differentiator. What differs is what happens to that data afterward: how many valuation models, how many property types, what the report pricing looks like.
Where the data comes from
Since a February 2026 amendment to Poland's Geodetic and Cartographic Law, the Register of Real Estate Prices (RCN) is public and free — any service can build on it. Both services compared here do. That means the sheer number of transactions in the database stopped being a real competitive edge for either side — what matters is what happens to the data afterward.
Quick comparison
| Feature | Centria | Cenogram |
|---|---|---|
| Valuation models (AVM) | 7 separate models — apartments, houses, land, farmland, commercial property, garages | 1 model, apartments only, labelled beta |
| Median valuation error | roughly 12.4% | roughly 14.9% (provider's own figures) |
| Parcel report — price | 99 zł, one-time, every topic included | token-based system — packages starting at 99 zł for 2,000 tokens, a report spends tokens per topic |
| Map with zoning layers (MPZP, general plan) | live, directly on the land map | no dedicated map layer — data lives in the text report |
| Access model | web app for buyers and investors | mainly API/MCP for developers and integrations |
Cenogram figures based on its publicly posted pricing and API documentation, as of August 2026 — check the provider's current pricing before deciding.
Where Cenogram has the edge
- Results-based billing — a stated token refund when a query returns no data, so you're mostly paying for hits.
- API-first: if you're building your own integration or developer tool, a ready-made set of endpoints can be faster to wire up than working through a web app by hand.
- Dedicated coverage catalogues for some signals (e.g. the asking-vs-transaction price spread, rental yield) that state upfront which cities are covered — useful when you need to know in advance whether a location is covered at all.
Where Centria has the edge
- Broader property-type coverage: buildable land, farmland, commercial property, and garages each get their own valuation model, not just apartments.
- A flat parcel-report price — 99 zł regardless of topic count, with no separate token system to track.
- Zoning layers (MPZP, the general plan, planning zones) and infrastructure networks directly on the map, not just a field in a report.
Frequently asked questions
To the extent both draw on the same public Register of Real Estate Prices — yes, in principle the same transactions are available in both. The differences show up in how the data is processed, classified, and presented afterward.
It depends on the need: if what matters is an automated valuation for land, farmland, or commercial property together with zoning layers on a map, Centria covers those property types natively. If you're building your own tool and need a ready-made API, Cenogram's offering is worth checking.
Based on the median error figures each service states, Centria's apartment model comes out more accurate (roughly 12.4% versus roughly 14.9%) — but that's a comparison of providers' stated methodologies, not an independent audit, so it's worth verifying the valuation on a specific address yourself.
