What Is an Energy Performance Certificate?
An Energy Performance Certificate (EPC) rates a property’s energy efficiency from A to G and suggests improvements. Issued by an accredited assessor, it examines insulation, heating, and glazing. EPCs are legally required for selling, renting, or building a home, helping reduce energy costs and improve property appeal.
This is what an Energy Performance Certificate looks like:
What Does an EPC Check?
An EPC assessment examines a property’s insulation, heating system, ventilation, and overall energy use. The assessor checks for draughts, double or triple glazing, and lighting efficiency, as well as how well the home retains heat. These factors determine the energy rating and highlight areas for improvement to reduce energy costs.
What is an EPC Rating?
An EPC rating ranks a property’s energy efficiency from A (most efficient) to G (least efficient). Higher ratings mean lower energy costs and better environmental impact, while lower ratings suggest potential improvements. A strong EPC score can increase a property’s resale value and attract more buyers or tenants.
Below is an EPC rating chart with the scores and ratings for every energy efficiency band.
| EPC Rating | Score |
|---|---|
| A (most efficient) | 92 and above |
| B | 81 to 91 |
| C | 69 to 80 |
| D | 55 to 68 |
| E | 39 to 54 |
| F | 21 to 38 |
| G (least efficient) | 1 to 20 |
How to Get an Energy Performance Certificate
Getting an EPC is a simple process, but it's important to use a qualified assessor to ensure accuracy. Here’s how to get one:
- Find an accredited EPC assessor – Use the UK government’s official database to ensure they are qualified.
- Book an appointment – Schedule a visit at a convenient time for the assessment.
- Home inspection – The assessor evaluates insulation, heating, glazing, and ventilation.
- Receive your EPC report – Your certificate, including the rating and recommendations, is typically issued within a few days.
This certificate is legally required when selling, renting, or building a home and helps buyers or tenants understand the property's energy efficiency.

How Long Does an EPC Last?
An EPC is valid for 10 years, regardless of how many times the property is sold or rented. However, if you’ve made major energy improvements—such as upgrading insulation, installing a new boiler, or adding solar panels—you may want to get a new EPC to reflect the improved rating and increase your property’s appeal.

How to Check Your EPC Rating?
You can check your current EPC rating online using the UK EPC Register. Simply enter your property’s postcode, select your address, and view the latest certificate. If your property doesn’t appear, it may not have an EPC, meaning you’ll need to book an assessment before selling or renting.
How Much Does an Energy Performance Certificate Cost?
The cost of an EPC varies based on property size and location, but on average, it ranges from £60 to £70. Larger homes and new-build properties typically require more detailed assessments, leading to higher fees. Different property types, such as terraced houses, flats, or detached homes, may also impact EPC costs and ratings.
Who Pays for an EPC?
- Home sellers – Must obtain and pay for an EPC before listing the property for sale.
- Landlords – Required to provide an EPC to potential tenants before renting out a property.
- Builders – Must supply an EPC for new-build homes upon completion.
Is an EPC a Legal Requirement?
Yes, an Energy Performance Certificate (EPC) is legally required when selling, renting, or building a home in the UK. Without one, you cannot market a property, and failing to comply can result in fines.
EPC Rules for Landlords:
- Rental properties must have a minimum EPC rating of E.
- Landlords cannot legally rent homes rated F or G unless they qualify for an exemption.
- Penalties of up to £5,000 apply for non-compliance.
Exemptions & Special Rules:
- Listed buildings may be exempt if energy improvements would alter their character.
- In Scotland, EPCs must be displayed inside the property, typically near the boiler or meter cupboard.
Checking your EPC status early ensures compliance and avoids delays when selling or renting a property.
How Can I Improve My Home’s EPC Rating?
Boosting your EPC rating can lower energy bills, make your home more attractive to buyers, and even increase property value. Here’s how you can improve your score.
Ways to Increase Your Energy Score
- Upgrade insulation – Loft, cavity wall, and floor insulation help retain heat.
- Switch to energy-efficient lighting – LED bulbs reduce energy use and last longer.
- Improve heating systems – Modern boilers, smart thermostats, and underfloor heating can boost efficiency.
- Install double or triple glazing – Better windows reduce heat loss and improve comfort.
- Consider renewable energy – Solar panels or heat pumps can significantly improve your EPC rating.
How Much Can Energy-Efficiency Improvements Cost?
According to a recent study by Nationwide Building Society, the average cost to improve a property's energy efficiency to band C is approximately £8,100. However, for properties rated F or G, the cost is considerably higher, averaging around £25,800.
The cost of improving energy efficiency depends on the size of your home and the type of upgrade:
- Loft insulation – £300–£500
- Cavity wall insulation – £800–£1,500
- New energy-efficient boiler – £2,000–£4,000
- Solar panels – £5,000–£8,000
- Double glazing – £3,000–£7,000
While some upgrades require a larger upfront cost, they can lead to significant long-term savings on energy bills and increase your home’s appeal to buyers.
