Upgrade to EPC C

- Disruption to tenants
- Grant timing uncertain
Best for: Properties currently EPC D with high yield and long hold horizon.
Sell before 2030
Pros

- Crystallise current value
- Redeploy capital
Cons
- CGT now
- Lose income stream
- Resale prices may drop as deadline approaches
Best for: EPC E/F properties with marginal yield and high upgrade cost.
Worked scenarios
EPC D, £8k upgrade, £900 pcm rent
| Option | Outcome |
|---|---|
| Upgrade | Payback ~3 years; usually worth it. |
| Sell | Only if other reasons to exit. |
EPC F, £18k upgrade, £650 pcm rent
| Option | Outcome |
|---|---|
| Upgrade | Long payback; consider only with grant funding. |
| Sell | Often the rational choice. |
