Energy Performance Certificates (EPCs) rate property energy efficiency from A (best) to G (worst). UK rental properties must meet Minimum Energy Efficiency Standards (MEES).

EPC Tracking in MaintenanceOS
Each property → EPC tab:
• Current rating + certificate number + expiry date
• Auto-warning: 6 months before expiry (EPCs valid 10 years)
• MEES status: Compliant / Exempt / Non-compliant
• Improvement recommendations from certificate
Exemptions
Valid exemptions (must be registered on PRS Exemptions Register):
• High cost: Improvements exceed £3,500 cap (domestic)
• 7-year payback: Improvements don't pay back in 7 years
• Wall insulation: Expert confirms not feasible
• Consent: Planning / listed building / tenant refusal
• Devaluation: Improvements reduce value >5%
MaintenanceOS tracks:
• Exemption type
• Registration date + expiry (5 years)
• Supporting evidence (quotes, expert reports)
• Auto-warning before exemption expiry
Improvement Planning
When EPC < E (or targeting C for future compliance):
1. Property → EPC → View Recommendations
2. See prioritised list: measure, indicative cost, rating impact
3. Create Improvement Plan:
- Select measures
- Set budget + timeline
- Assign to contractor / project manager
- Track progress
