EPC Upgrade Decision Matrix

Know what to upgrade first. Know what to leave alone.

EPC C for private rental properties is confirmed for 1 October 2030, and the new standard leads on a fabric performance metric. Spend on a heat pump before insulation and you'll hit the £10,000 cap without hitting the standard.

Enter a property's details once. The tool does the rest:

• Grades your building fabric automatically - Poor, Adequate, or Strong.
• Ranks six upgrade categories and applies a fabric penalty where it matters.
• Phases the work against your refinancing or sale window.
• Shows cost per EPC point and cost as a share of asset value.
• Flags when disposal beats retrofit.
