When buying or selling a property in the UK, you’ll often come across the term EPC rating. But what exactly is an EPC, and how does it affect your mortgage options? In this post, we break down everything you need to know about EPC ratings, how they’re calculated, and why they matter when buying a property.
What Is an EPC Rating?
An Energy Performance Certificate (EPC) provides an energy efficiency rating for a property, ranging from A (most energy-efficient) to G (least energy-efficient). The EPC shows how much energy a property uses, its carbon dioxide emissions, and suggestions for improving energy efficiency. It also provides a detailed breakdown of where energy is being used in the property and highlights specific areas that can be improved to reduce energy consumption and emissions.
EPC ratings are essential because they help potential buyers or renters understand the expected energy costs associated with a property. A higher EPC rating can indicate lower energy bills, while a lower rating may suggest that the property will be more expensive to heat and maintain. The report also includes recommendations for upgrades, such as adding insulation or installing a more efficient heating system, to improve the energy rating and reduce overall energy costs.
All properties being sold or rented in the UK must have an up-to-date EPC, so it’s something every buyer or renter will encounter. The EPC is valid for ten years, and it must be renewed if any significant changes are made to the property that could affect its energy efficiency.
How EPC Ratings Are Calculated
EPC ratings are calculated based on several factors, including:
- Insulation: How well walls, roofs, and floors retain heat. Properties with good insulation retain heat more effectively, reducing the amount of energy required for heating.
- Heating system: The type of boiler or heating system and its efficiency. Modern, energy-efficient boilers and renewable heating options tend to score better in EPC assessments.
- Windows and doors: Whether they are double-glazed or draught-proof. Double glazing reduces heat loss and helps maintain a comfortable indoor temperature, which improves the EPC rating.
- Renewable energy: Features like solar panels, heat pumps, or other renewable energy sources can improve the rating significantly. The presence of renewable technologies shows that the property can generate part of its own energy, reducing reliance on non-renewable energy sources.
An accredited energy assessor will visit the property to generate the EPC report and assign the property a rating. During the visit, the assessor will inspect elements like insulation thickness, heating controls, window quality, and any renewable energy systems. The assessor will then input all the collected data into a standardized software program, which calculates the final rating. This ensures that EPC ratings are consistent across different properties and reflect their overall energy efficiency.
How EPC Ratings Affect Mortgages
EPC ratings can directly impact your mortgage options, particularly as the UK moves towards greener living standards. Here’s how they can influence your mortgage:
- Green mortgages: Some lenders offer green mortgages, which provide better rates or incentives for properties with high EPC ratings (A or B). These mortgages reward energy-efficient homes with lower interest rates or cashback for buyers. Green mortgages are becoming more popular as lenders look to align themselves with the UK government’s sustainability targets and help homeowners make environmentally friendly choices.
- Lower EPC ratings may limit options: Properties with lower EPC ratings (E, F, or G) can be harder to finance. Many lenders are becoming stricter with low-rated properties, especially as government regulations push for better energy efficiency. Buy-to-let properties, for instance, must meet minimum EPC requirements to be rented out. Landlords must ensure their properties meet at least an E rating, or they could face legal repercussions, including fines and restrictions on renting out their properties.
- Future regulations: Upcoming regulations may make it more challenging to finance or sell homes with poor EPC ratings, making energy efficiency upgrades an important consideration. The UK government has set ambitious targets for reducing carbon emissions, and there is increasing pressure on homeowners to ensure that their properties meet higher energy efficiency standards. This could mean that homes with poor EPC ratings will become less desirable, and mortgage lenders may become more reluctant to lend against them. Additionally, grants or incentives may be offered to encourage homeowners to upgrade their properties and improve energy efficiency.
When You Need an EPC
You need an EPC if you are selling, renting, or building a property. Some scenarios include:
- Selling your home: An EPC must be provided to potential buyers. This allows buyers to make informed decisions about the energy efficiency of the property and any potential future costs they may face.
- Renting: Landlords must provide tenants with an EPC, and properties below an E rating cannot be legally rented. This ensures that tenants are aware of the likely energy costs associated with the property and encourages landlords to improve energy efficiency standards.
- New builds: New homes need an EPC before they are marketed. This ensures that all new properties meet current energy efficiency standards and helps buyers understand the likely running costs.
- Major improvements: Major changes like an extension or new heating system may require an updated EPC. If significant upgrades are made to the property, an updated EPC can show how the changes have improved the overall energy efficiency.
How to Get an EPC
To get an EPC, hire an accredited energy assessor who will inspect the property and provide a report. Costs range between £60 and £120, and you can find assessors through the government’s EPC Register website. The cost of an EPC can vary depending on the size and complexity of the property, as well as the assessor’s rates.
The process usually takes around one to two hours, depending on the property’s size. During the visit, the assessor will take measurements, inspect insulation, windows, doors, and heating systems, and check for any renewable energy installations. Once the inspection is complete, the assessor will generate a report that includes the EPC rating and detailed recommendations for improving the energy efficiency of the property.
What to Consider When Buying a Property with an EPC Rating
The EPC rating is more than just a letter on a certificate. It provides insight into potential future costs and improvements.
- Running costs: Higher-rated properties are generally cheaper to heat and maintain. This means lower energy bills and a more comfortable living environment, which is especially important during colder months when heating costs can be significant.
- Improvement costs: A low EPC rating may mean costly upgrades like new insulation, double glazing, or installing a more efficient heating system. When buying a property with a low EPC rating, it’s important to factor these potential costs into your budget. Some improvements, such as installing solar panels or upgrading to a modern boiler, can be expensive upfront but result in significant long-term savings.
- Resale value: Energy-efficient homes are increasingly attractive to buyers, which may boost resale value. With growing awareness of environmental issues and rising energy prices, properties with higher EPC ratings are likely to be in greater demand. A high EPC rating could make your property more appealing, faster to sell, and potentially allow you to achieve a higher sale price.
- Mortgage eligibility: As some lenders offer better rates for energy-efficient homes, a low EPC rating could affect your mortgage options. It’s worth checking whether a property’s rating will impact the type of mortgage products available to you. Green mortgages can offer lower interest rates and other incentives, which could save you money over the term of the mortgage.
Why EPC Ratings Matter
EPC ratings are playing an increasingly important role in the UK housing market, affecting everything from energy bills to mortgage rates. Understanding their impact helps you make informed decisions whether you’re buying, selling, or renting—potentially saving you money in the long run.
EPC ratings also tie into broader environmental goals, as the UK government aims to reduce carbon emissions and improve energy efficiency across the housing sector. By considering EPC ratings, buyers and renters can contribute to a greener future, while also saving on energy costs. Landlords, on the other hand, need to pay close attention to EPC requirements to ensure they meet legal standards and avoid penalties. Upgrading a property’s energy efficiency not only makes it more marketable but also aligns with the growing demand for sustainable living.
Ultimately, understanding and improving EPC ratings can benefit everyone involved in the property market—from reducing costs for homeowners and renters to meeting sustainability targets and enhancing property value. Whether you’re buying, selling, or renting, paying attention to EPC ratings can help you make smarter, more environmentally conscious choices, ensuring a positive outcome for your finances and the planet.
