GalimAI finds 3,207 active property-owning companies in Cardiff holding a property rated below EPC C - that is D, E, F or G. This is the stock that must be upgraded before the 2030 EPC C requirement, reflecting Cardiff's older housing and the retrofit pressure that comes with it. Every year closer to the deadline raises the cost and the urgency.
It is the Cardiff cut of the national 2030 EPC C cliff and the Wales picture, and pairs with off-market property in Cardiff.
Why it's an opportunity
The 2030 deadline is a built-in seller timer:
- Investors - 3,207 Cardiff owners facing an upgrade bill many won't fund; expect sales as the deadline nears.
- Developers and builders - sub-C stock is a refurbishment pipeline: buy at a condition discount, upgrade, capture the uplift.
- Stack a signal - below-C plus low cash is the owner who can't fund the fix and must sell.

How many Cardiff property owners are below EPC C?
GalimAI data shows 3,207 active Cardiff property-owning companies hold a property rated below EPC C (D, E, F or G).
Why does the 2030 EPC C line matter?
The rented sector must reach EPC C by 2030; owners below it face an upgrade bill, and many will sell rather than fund it.
How do I reach them?
Size Cardiff owners below EPC C in the portal and stack a low-cash signal to find those who can't fund the upgrade.
