10 Tips to improve your EPC rating in the UK

As a landlord, there are many factors to consider when getting the best value out of your investment property.

It’s not just about collecting rent checks; it involves a commitment to maintaining and enhancing the value of your investment property, ensuring the safety and comfort of your tenants, and complying with legal and environmental regulations.

In the ever-evolving landscape of real estate, one term has gained increasing prominence over the years: your EPC (Energy Performance Certificate) rating.

EPC ratings are a vital component in today’s property market, impacting both landlords and tenants alike. But what exactly is an EPC rating, and why is it so important?

What is an Energy Performance Certificate (EPC) rating?

An Energy Performance Certificate (EPC) rating serves as a benchmark of a property’s energy efficiency.

It is a standardised assessment that evaluates how effectively a building uses energy and produces associated carbon emissions.

What is an EPC rating check?

An EPC rating check is where an assessor evaluates:

  • The age, size, and type of property
  • The energy efficiency of the building fabric, such as walls, roof, and windows
  • The energy efficiency of the heating and hot water systems
  • The energy efficiency of lighting and appliances

This rating system assigns a grade, ranging from ‘A’ (the most energy-efficient) to ‘G’ (the least energy-efficient), to a property based on its energy performance.

Why is an EPC important?

The UK government has set a target of achieving net zero carbon emissions by 2050. EPC ratings are an important part of this target, as they can help to identify and improve the energy efficiency of buildings.

The government has introduced several policies to improve EPC ratings, including:

  • Requiring all new homes to be built to an EPC rating of C or above.
  • Introducing minimum EPC rating requirements for rented properties.
  • Offering financial incentives to homeowners to improve the energy efficiency of their homes.

Furthermore, energy efficiency is important due to the ability to reduce energy bills (which are becoming increasingly more unaffordable in the UK), the ability to improve the comfort and health of occupants and the lifespan of the property.

A property with a high EPC rating is likely to be more attractive to buyers and tenants, and it may also command a higher price.

What is the average EPC rating in the UK?

The average EPC rating in the UK is band D. This means that the average home is relatively inefficient and could benefit from energy efficiency upgrades, especially with the new government plan.

As of recent news, the government is considering extending the deadline for landlords to meet EPC standards, which were initially set for April 2025. This is due to the rising cost of energy and the difficulty of finding affordable energy efficient upgrades.

The government has also proposed a number of reforms to the EPC system, aimed at improving its accuracy and transparency. These reforms include introducing a new scoring system, making it easier for homeowners to understand their EPC rating, and requiring landlords to provide EPC certificates to prospective tenants.

How can an EPC rating impact my bills?

A new analysis has found that homes rated Energy Performance Certificate (EPC) band F could incur bills £685 higher than EPC band C homes under the new price cap. This is due to the rising cost of energy; less efficient homes require more energy to heat and cool.

If you are a landlord or homeowner, it is important to understand the EPC requirements and take steps to improve the energy efficiency of your property.

What are the steps I can take to improve my EPC rating?

  1. Insulation is Key

A significant factor in determining your property’s EPC rating is its level of insulation. Ensure that your property is adequately insulated, both in the walls and the roof.

Installing double glazing windows and doors can also help in maintaining a stable indoor temperature, reducing the need for excessive heating or cooling.

  1. Upgrade Your Heating System

An efficient heating system can make a substantial difference in your EPC rating. Consider replacing older boilers and heaters with energy-efficient models.

Make sure that the heating system is regularly serviced to ensure optimal performance.

  1. Install Energy-Efficient Lighting

Replace traditional incandescent light bulbs with energy-efficient LED or CFL bulbs. This simple switch not only reduces energy consumption but also improves your property’s lighting quality.

  1. Control Ventilation

Proper ventilation is vital for maintaining a healthy indoor environment.

Install extractor fans in bathrooms and kitchens to ensure adequate airflow without relying on opening windows, especially during colder months.

  1. Manage Draughts

Draughts can significantly impact your property’s energy efficiency.

Seal gaps around windows, doors, and any other openings to prevent heat from escaping and cold air from entering.

  1. Invest in Renewable Energy Sources

Consider incorporating renewable energy sources into your property, such as solar panels or wind turbines. These can generate electricity for your property, reducing your reliance on fossil fuels and improving your EPC rating.

  1. Upgrade Appliances

If you’re providing appliances with your rental units, ensure they have high energy efficiency ratings (A++ or A+++). This will not only attract eco-conscious tenants but also contribute to a better EPC rating.

  1. Educate Your Tenants

Encourage your tenants to be energy-conscious by providing them with energy-saving tips and guidelines.

Simple actions, such as turning off lights when not in use or reducing thermostat settings slightly, can collectively make a difference in your property’s energy consumption.

  1. Regular EPC Assessments

Arrange for regular EPC assessments to monitor the energy performance of your property. These assessments will help you identify areas for improvement and track your progress toward a higher EPC rating.

  1. Stay Informed About Regulations

Lastly, keep yourself informed about any changes in energy efficiency regulations and incentives in your area.

Staying compliant with these regulations not only benefits the environment but also ensures your property remains an attractive option for potential tenants.

Overall, boosting your property’s EPC rating is a win-win situation. It not only reduces your property’s environmental impact but also enhances its value and marketability.

By implementing these tips, you can take proactive steps towards a greener, more energy-efficient future for your investment properties.

EPC ratings are graded from A to G where A is the most efficient and G is the least. The average EPC rating in the UK is band D but there is a new initiative to make all EPC ratings to be in the C band.

An EPC rating check is where an assessor evaluates: the age, size, and type of property; the energy efficiency of the building fabric, such as walls, roof, and windows; the energy efficiency of the heating and hot water systems; and the energy efficiency of lighting and appliances.

A good EPC rating would be in the band A which means it has 92-100 SAP points. But an acceptable EPC rating would be between the A and D band.
