The U.K. rental landscape is littered with acronyms—EPC, CP12, PAT, EICR—but what do they actually mean? And when do you need each? This straightforward checklist cuts through the jargon so you stay legal, safe, and optimized for energy efficiency.

Energy Performance Certificate (EPC)

• A–G rating of property energy efficiency.

• Required before marketing a rental; valid for 10 years.

Gas Safety Certificate (CP12)

• Annual check by a Gas Safe registered engineer.

• Covers boilers, flues, pipes, and gas appliances.

Portable Appliance Testing (PAT)

• Visual inspections and electronic tests of all plug-in items.

• Recommended annually for rental properties.

Electrical Installation Condition Report (EICR)

• Detailed inspection of wiring and fixed electrical installations.

• Required every 5 years (or on change of tenancy for HMOs).

Legionella Risk Assessment

• Evaluation of water systems like tanks, pipes, and taps.

• Recommended between tenancies or after system changes.
