Which statement about the Energy Performance Certificate (EPC) is correct?

• A. It is valid for 5 years
• B. It identifies only energy usage
• C. It is valid for 10 years and includes energy efficiency rating, environmental impact rating, and may indicate Green Deal
• D. It is not required for property purchases

Answer: (C)

An Energy Performance Certificate is a document attached to property transactions that shows how energy-efficient a building is. The key point being tested is that an EPC is valid for ten years and it includes more than just energy usage: it records an energy efficiency rating (A–G) and an environmental impact rating (CO2 emissions). It may also indicate whether a Green Deal is in place or available for financing energy improvements. EPCs are required when selling or renting a property, so stating that they’re not required is incorrect. The combination of a 10-year validity, the two ratings, and the possible Green Deal indication makes this statement the correct one.
