Refreshing Property Data
External data sources update at different intervals. Here is how to refresh the data for a property.
Manual refresh
Open the property and click the Refresh Data button. This re-queries all six external sources and replaces the stored data with the latest results. The refresh typically takes 5-15 seconds.
When to refresh
- Before starting a new valuation — Ensure you have the most current data
- After a known data update — For example, after a new EPC is lodged or a Land Registry transaction completes
- If data seems stale — Street View images and planning data update periodically
Update frequency by source
| Source | Typical update frequency |
|---|---|
| EPC | When a new certificate is lodged (on sale, let, or construction) |
| Land Registry | Monthly batches, 2-4 month lag |
| Flood Risk | Annually by the Environment Agency |
| Planning | Varies by local authority (daily to monthly) |
| VOA | Rating list revaluation every 3 years (next: 2026) |
| Street View | Google updates imagery on a rolling basis (typically every 1-3 years) |
Data persistence
Fetched data is stored against the property record. It is not re-fetched automatically. This means your valuation report will reference the data as it was at the time you last fetched — which is the correct approach for audit trail purposes.
If you need to demonstrate that you used current data at the valuation date, refresh the data on or close to your effective valuation date and note this in your report.
