What is an Energy Performance Certificate in Property?
An Energy Performance Certificate (EPC) rates the energy efficiency of a property on a scale of A to G, with A being the most energy-efficient. EPCs help potential buyers, tenants, and owners make informed decisions by providing a clear view of a property’s energy consumption and associated costs. In many cases, an EPC is a legal requirement, especially in property rentals and sales, as it demonstrates compliance with sustainability standards.
What is an EPC rating?
An EPC (Energy Performance Certificate) rating measures the energy efficiency of a property on a scale from A to G. 'A' indicates the most energy-efficient homes, while 'G' represents the least efficient. The rating is based on factors like insulation, heating systems, and energy usage. A higher EPC rating can lead to lower energy bills and reduced environmental impact.

How to Obtain an Energy Performance Certificate?
- Locate a Certified Energy Assessor: Choose an accredited energy assessor to perform the evaluation.
- Schedule an Assessment: Book an assessment at a convenient time; this usually takes about 1-2 hours.
- Receive the Report: Once the assessment is complete, the energy assessor will provide you with the EPC report.
- Review and Implement Suggestions: The report includes recommendations for improving energy efficiency.
Steps Involved in the Energy Assessment Process
An EPC assessment is carried out through the following steps:
Step 1: Initial Review
The assessor starts by gathering background information about the property, including its layout, age, known issues, and any renovation plans. This helps identify areas that may require closer inspection during the assessment.
Step 2: Exterior Inspection
The outside of the property is examined, including walls, windows, doors, roofing, and overall building orientation. Factors such as shading from nearby structures or trees are noted, as they influence heat gain, heat loss, and ventilation.
Step 3: Interior Inspection
The assessor evaluates insulation quality, heating and cooling systems, hot water setup, ventilation, and window sealing. Areas like the attic, basement, and upper floors may also be examined to check insulation levels and structural energy efficiency.
Step 4: Energy Performance Analysis
Using specialised software and diagnostic tools, the assessor analyses the collected data to determine the property's energy performance. This may include air tightness checks or thermal imaging to identify heat loss and insulation gaps.
Step 5: Report Generation
A detailed EPC report is then prepared. It provides the property’s official energy efficiency rating (A to G), outlines its energy characteristics, and offers recommendations for improving efficiency and reducing energy consumption.
What else can an EPC certificate tell me about my property?
EPCs provide both numerical scores and letter grades that reflect a property’s current and potential energy performance, along with recommended improvements. These suggestions can boost efficiency, reduce energy costs and enhance the property’s appeal to future buyers.
Typical energy-saving recommendations may include:
- Adding insulation such as loft, roof, floor or wall insulation
- Installing energy-efficient lightbulbs
- Upgrading to double-glazed windows
- Replacing an old or inefficient boiler
- Installing solar panels
- Enhancing the central heating system
A higher EPC rating generally means lower running costs and better overall energy performance.
Key Benefits of Energy Performance Certificates in Property
- Lower Utility Bills: A higher-rated EPC means lower energy costs.
- Improved Property Appeal: Properties with good EPC ratings are attractive to environmentally conscious buyers.
- Contribution to Sustainability: EPC ratings encourage energy-efficient upgrades, reducing the carbon footprint.
- Legal Compliance: EPCs are often required by law, particularly for rental properties.
How much does an energy performance certificate cost?
An EPC is a document that assesses your property’s energy performance, outlining how much energy it uses and the estimated running costs. It also provides practical recommendations to help improve efficiency and reduce overall energy consumption.
An EPC is valid for ten years, after which a new assessment may be required to reflect any changes or improvements made to the property.
Why should I get an Energy Performance Certificate?
An Energy Performance Certificate (EPC) provides insights into your home's energy efficiency. It highlights areas for improvement, helping you reduce energy bills and lower carbon emissions.
If you plan to sell or rent out your property, having a valid EPC is a legal requirement before listing it on the market. The certificate must be issued by a qualified domestic energy assessor.
For buyers or tenants, the EPC rating allows for easy comparison of energy efficiency across different properties. In some regions, like Scotland, it's mandatory to display the EPC rating prominently, such as near the boiler or the meter cupboard.
The EPC also includes suggestions to enhance your energy rating. If you implement the recommended upgrades, it’s a good idea to obtain an updated certificate to reflect the improved energy performance of your property.

Common Misconceptions about Energy Performance Certificates
“EPC is Only for New Buildings”: EPCs are required for both old and new buildings.
“EPC Ratings Don’t Change”: Ratings can improve with energy-efficient upgrades.
“EPCs Are Only for Residential Properties”: Commercial properties can also benefit from EPCs.
What are the minimum energy efficiency standards in India?
India has been steadily advancing its energy efficiency regulations, particularly in the real estate and construction sectors. The Bureau of Energy Efficiency (BEE) under the Ministry of Power has introduced energy performance standards for buildings, including the Energy Conservation Building Code (ECBC). While there is no nationwide minimum EPC rating requirement like in the UK, the ECBC sets benchmarks for the design and construction of energy-efficient commercial buildings.
For residential properties, energy efficiency is becoming increasingly important, especially in urban housing and rental markets. State governments and urban development authorities are gradually encouraging builders and landlords to comply with ECBC guidelines and BEE's star rating systems for appliances and construction materials.
Although rental restrictions based on EPC ratings are not yet mandatory, future policies may move toward requiring a minimum energy performance standard to promote sustainable housing and reduce carbon emissions in India's growing real estate sector.
How can I improve my Home’s EPC rating?
Improving your home’s EPC rating becomes easier when you focus on practical upgrades that reduce energy waste and boost overall efficiency.
- Add proper insulation: Install roof, wall and floor insulation to maintain indoor temperatures and reduce dependence on cooling or heating systems.
- Seal gaps and leaks: Use weather strips or sealants around windows, doors and electrical fittings to prevent unwanted air leakage.
