Landlords: how to make your property more energy efficient

The UK Government is looking at improving energy efficiency standards for private tenants that could save them an estimated £240 a year on their annual energy bills. 

From 2030, the UK Government’s proposal would mean all private landlords will have to ensure their properties have a minimum Energy Performance Certificate (EPC) rating of C or above. This proposal would extend to England and Wales. 

Less than half (48%) of private rented homes in England currently have an EPC rating of C and above. Currently, the minimum EPC rating for private rental properties is E. 

It’s estimated that it will cost landlords between £6,100 and £6,800, on average, to upgrade their properties in line with the new standards by 2030. 

The UK Government has opened a consultation for landlords and tenants to share their views. The consultation closes on 2 May 2025. 

All rental properties in Great Britain are required to have an Energy Performance Certificate (EPC). An EPC gives a property an energy efficiency rating from A (the most efficient) to G (the least efficient). Having a good EPC rating can mean lower energy bills for tenants and a reduced home carbon footprint.

EPCs can help both landlords and tenants understand the energy performance of their home, as well as identify areas for improvement.

As a landlord, you must get a new EPC every 10 years. It’s your responsibility to provide tenants with a valid EPC.

For properties sold or let in England and Wales, the minimum energy efficiency standard requires them to have a minimum EPC rating of E or above. These rules apply to all new and existing tenancies.

Landlords are responsible for providing new tenants with a copy of the property’s EPC when they move in. You can find it via the Energy Performance of Buildings Register (in England and Wales) or the Scottish EPC Register (in Scotland). Check to see if yours is in date.

The previous UK Government had proposed changes to the minimum energy efficiency standard for England and Wales. Under the changes, all rental properties would need an EPC rating of ‘C’ or above by 2025 for new tenancies and 2028 for existing tenancies. However, it was announced in September 2023 that these proposals would not be going ahead.

In its manifesto, the new UK Government committed to making sure homes in the private rented sector meet minimum energy efficiency standards by 2030. This suggests they would reverse the change. In the King’s Speech, they committed to introducing a Decent Homes Standard for the private rented sector. We don’t currently know the details of this.

The Scottish Government’s Heat in Buildings Bill consultation proposes new minimum energy efficiency standards for private landlords in Scotland to meet by 2028. The new standards will require all privately rented properties to install a list of energy efficiency improvements. It also proposes that building owners will need to replace polluting heating systems like gas, oil and LPG boilers with clean ones by 2045. Examples of clean heating systems include:

• heat pumps
• modern electric storage heaters
• district heating

In its Energy Performance Certificate (EPC) Reform Consultation, the Scottish Government also proposes to reduce the validity period of EPCs from 10 to five years. This means you’d need an updated EPC if for properties you put up for rent or sale, if the current one is older than five years. This is intended to give prospective owners and tenants more up to date information about the building.

To get your property up to the minimum energy efficiency standard, follow the steps below.

Arrange an energy assessment

Understanding your property’s current EPC rating is a good place to start. To get an updated EPC rating for your property, you need to have it assessed by an approved domestic energy assessor. In Scotland, there’s a different process to find an approved assessor.

Landlords and letting agents need to give tenants at least 24 hours’ written notice before any property visits. You can arrange a suitable time with your tenants for someone to assess the property.

Find out what improvements you can make

Once you have an up-to-date report, read through the recommendations included in your property’s EPC report.

In England and Wales, you’ll never be required to spend more than £3,500 on the recommended improvements to reach the minimum energy efficiency standard. If the recommended improvements cost more than £3,500, you can apply for high-cost exemption via the PRS Exemptions Register.

You can fund the improvements to your property through self-funding, third-party funding, or a combination of the two. Find out more about the different funding options.

Decide which measures to implement

While the biggest energy savers will depend on the property type, typical examples include:

• Installing insulation, such as solid wall, cavity wall or loft insulation.
• Upgrading heating systems, such as an energy efficient boiler.
• Draught-proofing gaps and cracks.
• Replacing existing windows and doors with double glazed windows or energy efficient doors.
• Installing renewable energy systems, such as solar panels or heat pumps.

Smaller improvements include:

• Upgrading to LED light bulbs.
• Installing a smart meter.

Exemptions to improvements

Some properties can be exempt from the minimum energy efficiency standards. These exemptions can be due to affordability, mortgage lender consent refusal, or structural issues.

If a property meets the criteria for any exemptions, landlords will need to register it on the PRS Exemptions Register. An exemption lasts for five years.
