Gas Safety Certificate (CP12)
- Statute
- Gas Safety (Installation and Use) Regulations 1998 reg 36(6)–(7)
- Deadline
- Before move-in (and within 28 days of every annual renewal thereafter)
- Penalty for non-service
- Unlimited fine + up to 6 months imprisonment. Does not bar a Section 8 claim (only the deposit rules do), but it hands a tenant a disrepair argument and weighs against you on discretionary grounds.
- Service rule landlords forget
- Email the latest CP12 PDF to the tenant. A copy in your filing cabinet is not service — the court wants the moment of delivery.
