EPC Ratings: Why they matter and how Estatio can help

What is an EPC rating?

An Energy Performance Certificate (EPC) is a legal requirement when selling a home in the UK. It rates your property's energy efficiency on a scale from A (most efficient) to G (least efficient). This helps buyers estimate energy costs and plan their budget accordingly.

How is an EPC rating measured?

Several factors determine your EPC rating, including:

• Insulation: Loft, cavity wall, and floor insulation are assessed for their ability to retain heat.
• Heating System: The efficiency of your boiler and heating controls is evaluated.
• Windows & Doors: Double or triple glazing can improve your rating.
• Renewable Energy: Features like solar panels or heat pumps can boost your score.

‍

Why is a good EPC rating important?

A higher EPC rating comes with several benefits:

• Lower energy bills: A more efficient home costs less to heat and power.
• Reduced carbon footprint: Energy-efficient homes are better for the environment.
• Increased property value: Homes with an A or B rating are more attractive to buyers and may sell for a higher price.

EPC validity & government support

EPCs are valid for 10 years, but most buyers prefer an up-to-date certificate. If your rating is low, you’ll receive recommendations on how to improve it.

In some cases, the government may offer funding to help low-income homeowners upgrade their energy efficiency. This programme is called the Help to Heat grant, which has the government foot the bill for improvements to your home's energy efficiency.

EPCs for private landlords

Beginning December 31, 2025, private landlords must ensure their properties hold an EPC rating of C or above for new tenants. Existing tenants can stay in homes rated E or above until 2028, as permitted by the new EPC regulations.

The government aims for all privately rented homes in England and Wales to achieve a C rating or higher by 2030.

Key Points:

• Energy efficiency upgrades: Landlords are not required to spend more than £3,500 (including VAT) on energy efficiency improvements. If costs exceed this, you may be eligible for an exemption. 
• Fines: From 2025, fines for breaching EPC regulations will increase from £5,000 to £30,000.
• Impact on tenancies: These changes apply to new tenancies starting in 2025. Existing tenancies will not be affected until 2028.

EPC assessment: An EPC assessor must carry out the property assessment. You can find a registered assessor through the government website.

For more information, it’s essential to visit the official website and ensure compliance.

The average EPC rating in the UK is D, moderately efficient but with room for improvement. Enhancing your EPC with these upgrades can make your home more comfortable, cost-effective, and appealing to buyers when you are looking to sell.
