EPC: Energy Performance Certificates
What is an EPC?
An Energy Performance Certificate (EPC) is a document that rates the Energy Efficiency of a building. It provides information about a building’s energy performance, including its heating, insulation, and lighting. EPCs are required by law in England and Wales for most buildings that are being sold or rented.
Why are EPCs important?
EPCs are important for a number of reasons:
- They help to improve the energy efficiency of buildings. By providing information about a building’s energy performance, EPCs can help homeowners and landlords to identify areas where they can make improvements to reduce their energy consumption and save Money on their energy bills.
- They help to reduce carbon emissions. By improving the energy efficiency of buildings, EPCs can help to reduce the amount of carbon dioxide that is released into the Atmosphere.
- They help to create a more sustainable built Environment. EPCs are an important part of the government’s strategy to create a more sustainable built environment.
How are EPCs created?
EPCs are created by qualified energy assessors. The assessor will visit the building and carry out a survey to assess its energy performance. The assessor will then use this information to create an EPC, which will include a rating from A (most efficient) to G (least efficient).
What information is included in an EPC?
An EPC will include the following information:
- The building’s energy performance rating. This is a rating from A (most efficient) to G (least efficient).
- The building’s energy consumption. This is measured in kilowatt-hours (kWh) per square metre per year.
- The building’s carbon dioxide emissions. This is measured in tonnes of CO2 per year.
- Recommendations for improving the building’s energy performance. These recommendations may include things like installing insulation, upgrading heating systems, or replacing windows.
- The date the EPC was created.
- The name and contact details of the energy assessor.
EPC Ratings
The EPC rating is a key part of the EPC. It is a simple way of understanding the energy efficiency of a building. The higher the rating, the more energy-efficient the building is.
| Rating | Description |
|---|---|
| A | Very energy efficient |
| B | Energy efficient |
| C | Average energy efficiency |
| D | Below average energy efficiency |
| E | Poor energy efficiency |
| F | Very poor energy efficiency |
| G | Extremely poor energy efficiency |
EPC Costs
The cost of an EPC can vary depending on the size and type of the building. However, the average cost is around £100-£150.
EPC Validity
EPCs are valid for 10 years. After this time, they will need to be renewed.
EPC and the Law
EPCs are required by law in England and Wales for most buildings that are being sold or rented. This includes:
- Residential buildings.
- Commercial buildings.
- Industrial buildings.
EPC Exemptions
There are some exemptions from the EPC requirements. These include:
- Buildings that are used for less than four weeks per year.
- Buildings that are used for religious worship.
- Buildings that are listed as being of special architectural or historic interest.
EPC and Energy Efficiency Improvements
EPCs can help to identify areas where energy efficiency improvements can be made. These improvements can help to reduce energy consumption and save money on energy bills.
EPC and the Environment
EPCs play an important role in reducing carbon emissions and creating a more sustainable built environment. By improving the energy efficiency of buildings, EPCs can help to reduce the amount of carbon dioxide that is released into the atmosphere.
Frequently Asked Questions

Q: Why do I need an EPC?
A: EPCs are required by law in England and Wales for most buildings that are being sold or rented.
Q: How much does an EPC cost?
A: The cost of an EPC can vary depending on the size and type of the building. However, the average cost is around £100-£150.
Q: How long is an EPC valid for?
A: EPCs are valid for 10 years. After this time, they will need to be renewed.
Q: What information is included in an EPC?
A: An EPC will include the building’s energy performance rating, energy consumption, carbon dioxide emissions, recommendations for improving energy performance, the date the EPC was created, and the name and contact details of the energy assessor.
Q: What is the EPC rating?
A: The EPC rating is a simple way of understanding the energy efficiency of a building. It is a rating from A (most efficient) to G (least efficient).
Q: How can I improve my building’s energy efficiency?
A: There are a number of ways to improve your building’s energy efficiency, such as installing insulation, upgrading heating systems, or replacing windows.
Q: What are the benefits of improving my building’s energy efficiency?
A: Improving your building’s energy efficiency can help to reduce your energy consumption and save money on your energy bills. It can also help to reduce carbon emissions and create a more sustainable built environment.
Q: Where can I find an energy assessor?
A: You can find a qualified energy assessor through the government’s website or through a reputable energy assessment company.
Q: What happens if I don’t have an EPC?
A: If you are selling or renting a building that is required to have an EPC, you could face a fine.
Q: What are the exemptions from the EPC requirements?
A: There are some exemptions from the EPC requirements, such as buildings that are used for less than four weeks per year, buildings that are used for religious worship, and buildings that are listed as being of special architectural or historic interest.
Q: What is the difference between an EPC and an energy audit?
A: An EPC is a basic assessment of a building’s energy performance. An energy audit is a more detailed assessment that can identify specific areas where energy Savings can be made.
Q: What is the role of the government in EPCs?
A: The government has introduced legislation requiring EPCs for most buildings that are being sold or rented. The government also provides funding for energy efficiency improvements.
Q: What is the future of EPCs?
A: The government is committed to improving the energy efficiency of buildings. It is likely that EPCs will become even more important in the future, as the government continues to introduce policies to reduce carbon emissions and create a more sustainable built environment.
