Energy Efficiency Tips on Improving your EPC Rating
Improving your EPC rating is a priority for many landlords who want to reduce energy use, make their property more comfortable and protect the long-term appeal of their investment. Improving energy performance can help reduce running costs for tenants and make a rental home more attractive when it is time to market it.
For private rented homes in England and Wales that are covered by the Minimum Energy Efficiency Standard, landlords generally cannot let a property with an EPC rating below E unless a valid exemption has been registered. Before spending money on upgrades, check your EPC report first, as it includes recommendations tailored to the property.
1. Start With Your Existing EPC Report
The most sensible place to start is the EPC itself. It provides a rating from A to G and suggests improvements that could help improve the home’s energy performance.
The recommendations are listed in an order that shows the likely impact of different measures. This helps you decide whether low-cost changes, such as LED lighting and draught proofing, should come before larger investments like insulation, windows or a new heating system.

If your property has changed significantly since the EPC was issued, it may be worth arranging a new assessment once improvement works are complete.
2. Improve Loft And Wall Insulation
Insulation is often one of the most effective ways to improve your EPC rating. Heat escapes through poorly insulated lofts, walls and floors, which can make a property harder and more expensive to heat.
Loft insulation can be a practical starting point for many homes, while cavity wall insulation may be suitable for some properties. Older or solid-wall homes may need more specialist advice, as the wrong type of insulation can cause problems with moisture or the fabric of the building.
Always consider the property type, construction and any planning restrictions before arranging works.
3. Upgrade Windows And Doors
Older single-glazed windows and poorly fitted doors can let heat escape and create draughts. Replacing them with efficient double glazing, improving seals or adding draught proofing can help make a home warmer and quieter.
This can be particularly worthwhile in older rental properties where tenants may otherwise rely heavily on heating. However, listed buildings and properties in conservation areas may need consent before windows or doors are replaced.
4. Review Your Heating System
Heating has a major effect on energy efficiency. If your boiler is old or unreliable, upgrading to a modern, efficient system may help improve comfort and reduce energy use.
Smart heating controls and programmable thermostats can also help tenants manage their heating more effectively. Make sure any system you install is suitable for the size and layout of the property, rather than choosing an upgrade based on the EPC rating alone.
5. Switch To LED Lighting
Replacing old light bulbs with LEDs is one of the simplest and most affordable energy-saving improvements available. LEDs use less energy and typically last longer than traditional bulbs.
While this change alone is unlikely to transform a low EPC rating, it is a quick win and can support other measures such as insulation and heating upgrades.
6. Consider Renewable Energy Options
For some properties, renewable technology such as solar panels can make a significant difference to energy performance. Solar panels can reduce reliance on grid electricity and may improve the property’s EPC rating, depending on the wider specification of the home.
These upgrades require a higher initial investment, so look carefully at installation costs, roof suitability, planning requirements and likely long-term benefit before proceeding.
7. Do Not Ignore Draughts And Ventilation
Small gaps around windows, doors, chimneys and pipework can make a property feel cold and increase heat loss. Draught proofing may be a cost-effective improvement, particularly when combined with insulation.
However, do not block essential ventilation. Bathrooms, kitchens and areas with fuel-burning appliances need suitable ventilation to help reduce condensation, damp and mould risks.
EPC Rules For Landlords
Current government guidance confirms that landlords of domestic private rented properties covered by the rules cannot let or continue to let a home rated F or G unless they have a valid exemption in place.
The current cost cap is £3,500 including VAT. If you cannot improve a qualifying property to an EPC E within that cap, you may need to install all relevant improvements possible within the cap and register the appropriate exemption.
For the latest requirements, exemptions and penalties, read the GOV.UK minimum energy efficiency guidance for landlords.
Thinking Of Making Energy Upgrades?
The best improvements will depend on your property, current EPC recommendations and budget. Oakmans can help landlords keep their property appealing to tenants and support them with lettings and property management services.

FAQs
What is the fastest way to improve an EPC rating?
The best option depends on the property, but loft insulation, LED lighting, draught proofing and heating controls can be practical first steps. Check the recommendations on your current EPC report before spending money.
What EPC rating does a rental property need?
For domestic private rented properties covered by the Minimum Energy Efficiency Standard in England and Wales, the minimum rating is generally E. A property rated F or G may only be let if a valid exemption applies and has been registered.
Can new windows improve an EPC rating?
They can. Replacing single glazing or inefficient windows with energy-efficient double glazing can reduce heat loss and may improve the EPC rating.
Do solar panels improve an EPC rating?
Solar panels can improve an EPC rating, but the impact depends on the whole property and how its energy performance is assessed.
Can I let a property with an F or G EPC rating?
Generally, no, unless your property qualifies for an exemption and that exemption has been registered. Check the current government guidance before marketing or letting the property.
Does every energy-saving upgrade increase an EPC rating?
Not always. EPC ratings are based on a set calculation, so the impact of an upgrade will depend on the property and the measures already in place. Always check the EPC recommendations first.
