How Zhaku Scores Work
A plain-English guide to Zhaku scores.
Zhaku scores are there to help users understand how much useful local evidence and signal coverage Zhaku currently has for a postcode. They are designed to support research - not replace due diligence.
Main score
Zhaku Research Score
This is the main postcode score shown by Zhaku. It runs from 0 to 100. In simple terms, higher is generally better because it usually means Zhaku currently has stronger evidence, broader data coverage, or fewer cautionary signals in that postcode.

What it is not
This score is not a property valuation, not investment advice, not legal advice, not survey advice, and not a recommendation to buy, sell, rent, or avoid an area.

How to use it
Use it as a research support score only. It should sit alongside legal checks, survey findings, lending checks, insurance checks, planning review, and property-specific analysis.

Crime score
0-100 scale
This is a simplified score based on the crime snapshot currently available to Zhaku. Higher is generally better. A lower score suggests a more cautionary crime signal in the current snapshot. For example, a Crime score of 38 means the current crime snapshot looks more cautionary than supportive. It does not mean “38 crimes” and it is not a crime prediction.

Flood score
0-100 scale
This is a simplified score based on nearby flood-monitoring context returned in the current lookup. Higher is generally better. Lower scores can suggest more flood-related context nearby or more flood-monitoring areas that may need closer review.

Data coverage score
0-100 scale
This reflects how much usable Zhaku data is currently available across its postcode intelligence layers. Higher is better. A lower score usually means Zhaku still has thinner data coverage for that postcode.

Important limitations
Postcode-level signals are not the same as property-specific due diligence.
A strong score does not mean a property is a good investment or suitable for a particular user.
A weak score does not necessarily mean an area is poor - it may reflect limited data coverage or more cautionary signals in the current Zhaku snapshot.
Users should combine Zhaku outputs with legal checks, surveys, lender criteria, insurance checks, planning review, and property-specific analysis.
