Property condition varies street by street, and in London it varies borough by borough. Measured as a share of each borough's owners, Croydon has the highest concentration of below-standard stock (~60.8%) and City of Westminster the lowest (~40.2%). Condition is a EPC story under the bonnet - a property rated below EPC C faces the 2030 upgrade line and one rated F or G cannot legally be re-let - and it is one of the clearest guides to where the value-add and the quieter, off-market investment opportunities sit.
Poor-condition stock is where the value-add sits. You can see which owners hold it in London and reach them directly.

Best and worst areas
On a share basis the poorest-condition borough in London is Croydon (~60.8% of owners hold below-standard stock), and the best is City of Westminster (~40.2%). For the investor, the higher-share areas are where refurbishment stock - and owners who may prefer a quiet sale to a costly upgrade - are most concentrated.

Why it's an opportunity
Condition maps opportunity. The higher-share areas above hold the most below-standard stock relative to their size - the sharpest place to look for value-add and off-market deals in London.
- Value-add - below-standard stock bought at a condition discount and upgraded captures the uplift.
- Quiet approach - owners facing a 2030 upgrade bill often prefer a direct, off-market sale to funding works.
- Local focus - a borough-level view lets you concentrate effort where condition pressure is highest.
