EPC for Listed Buildings in London: What Owners Need to Know
Owning a listed or traditionally constructed property in London can make energy-efficiency decisions more complicated than they are for a modern home.
Older properties can have solid walls, original windows, historic features and construction methods that need to be treated carefully. At the same time, property owners may still need to consider Energy Performance Certificate (EPC) requirements when selling or letting the property.
So, what should you know about an EPC for listed buildings in London?
This guide explains how EPCs can apply to historic properties, what owners should check before making improvements and where to find reliable information before selling or renting.
Do Listed Buildings Need an EPC?
A listed building is not automatically exempt from EPC requirements simply because it is listed.
The rules depend on the circumstances of the property and whether meeting the relevant minimum energy-performance requirements would unacceptably alter its character or appearance.
GOV.UK guidance explains that some listed buildings may be exempt where the required energy-efficiency work would cause unacceptable changes to the building. Owners should therefore check the circumstances of their particular property rather than assuming that listing status automatically means an EPC is unnecessary.
For official guidance, see the GOV.UK Energy Performance Certificate guidance.
Historic England also provides guidance on EPCs and energy efficiency for listed and traditionally constructed buildings.
Why Historic London Properties Can Be Different
Many London properties were constructed long before modern energy-efficiency standards existed.
Depending on the building, you may find:
Solid brick or stone walls
Single-glazed or original windows
Traditional roof construction
Older floors
Original fireplaces
Historic doors
Traditional plasterwork
Older heating systems
Period architectural details
These features can affect both the energy performance of the property and the type of improvements that are practical.
For example, replacing original windows with modern units may not be appropriate for a building where preserving historic character is important.
This is one reason owners should avoid treating an EPC recommendation as an instruction to immediately carry out every suggested improvement.
EPC Recommendations Should Be Considered Carefully
An EPC contains recommendations for possible improvements to the property’s energy performance.
However, recommendations need to be considered alongside the building itself.
A recommendation that makes sense for a modern property may not be suitable for a Victorian, Edwardian or Georgian building.
Factors to consider include:
The age of the building
Construction materials
Existing insulation
Window design
Heating system
Ventilation
Historic features
Listed status
Conservation requirements
Planning considerations
The intended use of the property
If you have recently received an EPC, our guide to EPC Recommendations for London Properties explains how to review the recommendations before deciding what to do next.
What About Properties in Conservation Areas?
Listed buildings are not the only properties that may have heritage considerations.
London contains many conservation areas with buildings that have architectural or historic importance.
A property does not necessarily need to be individually listed to have restrictions or planning considerations affecting alterations.
If you own a property in a conservation area, it can therefore be sensible to check the relevant local planning and conservation requirements before carrying out external changes.
Historic England provides useful information about energy efficiency and EPC considerations for listed buildings and properties in conservation areas.
You can read the Historic England guidance on EPCs and Minimum Energy Efficiency Standards for additional background.
Should You Upgrade a Historic Property Before an EPC Assessment?
Usually, the purpose of an EPC assessment is to assess the property’s existing characteristics.
You do not need to renovate a property simply because you are arranging an EPC assessment.
Instead, make sure the assessor can access the relevant parts of the property and provide any useful information you have about previous improvements.
For example, you may have records relating to:
Boiler replacement
Loft insulation
Wall insulation
Double glazing
Solar panels
Heating controls
Renewable energy systems
Extensions or alterations
If you are preparing for an assessment, our EPC assessment preparation checklist explains what you can have ready before the assessor arrives.
What If the EPC Rating Is Low?
A low EPC rating does not necessarily mean that you should immediately make major changes to a historic property.
Start by understanding why the rating was given and review the recommendations on the certificate.
The appropriate approach can depend on the construction and condition of the building.
For example, an older property may require a different approach to insulation or heating improvements than a modern property.
Historic England notes that EPC methodologies can sometimes underestimate the thermal performance of traditionally constructed buildings and that some standard recommendations may not be appropriate for historic buildings.
This makes it particularly important to consider the building as a whole rather than focusing only on one EPC recommendation.
Can You Sell a Listed Property Without an EPC?
This depends on whether the property qualifies for an applicable exemption.
GOV.UK guidance states that listed buildings can fall within an EPC exemption where work needed to meet minimum energy-performance requirements would unacceptably alter the building’s character or appearance.
The exemption should not simply be assumed because a property is listed.
If you are unsure, check the current government guidance and consider obtaining appropriate advice, particularly where planning or conservation issues are involved.
You can also use the official GOV.UK Find an Energy Certificate service to check whether an EPC already exists for the property.
What If You Are Renting Out a Listed Property?
Landlords need to consider EPC and Minimum Energy Efficiency Standards requirements when letting property.
For properties that require an EPC, the current private rented sector rules generally require the property to meet the applicable minimum standard unless a valid exemption applies.
The government maintains an official register for private rented sector energy-efficiency exemptions.
You can check the GOV.UK private rented sector energy standards exemption guidance if you need to understand the exemption process.
If you are preparing a London rental property, our recent EPC for Rental Property in London: Landlord Checklist covers the wider process of checking your EPC, preparing the property and getting the listing ready.
What Should You Do Before Booking an EPC?
If your London property is historic, listed or traditionally constructed, a few simple checks can help.
1. Check for an Existing EPC
First, search the official EPC register.
You may already have a valid certificate, meaning another assessment may not be necessary immediately.
2. Check the Property Status
Find out whether the property is:
Individually listed
Within a conservation area
Traditionally constructed
Subject to other planning or heritage restrictions
3. Gather Previous Improvement Records
Keep records of relevant work such as insulation, heating upgrades and window replacements where available.
4. Make the Property Accessible
Make sure the assessor can access relevant heating systems, controls and other areas needed for the assessment.
5. Do Not Assume Every Recommendation Must Be Followed
Review the recommendations in the context of the property.
For heritage properties, some improvements may require additional consideration before they are carried out.
6. Check the Current Rules
EPC and private rental requirements can change, so use current GOV.UK guidance rather than relying on older articles or forum discussions.

Final Checklist for Listed and Historic London Properties
Before selling or letting your property, consider the following:
☐ Check whether an existing EPC is valid
☐ Check whether the property is listed
☐ Check whether it is within a conservation area
☐ Review the EPC rating
☐ Read the EPC recommendations
☐ Gather records of previous energy improvements
☐ Make relevant areas accessible for the assessor
☐ Check current GOV.UK requirements
☐ Consider planning or conservation requirements before making alterations
☐ Arrange an EPC if one is required
☐ Prepare the remaining property marketing information
Final Thoughts
An EPC for listed buildings in London can require a little more consideration than an EPC for a modern property.
The important point is not to assume that a listed building is automatically exempt or that every EPC recommendation should immediately be carried out.
Start by checking whether the property already has a valid EPC and whether any relevant exemption applies. Then consider the building’s construction, historic features and planning requirements before making energy-efficiency improvements.
For the latest requirements, always check official government guidance and consider specialist advice where planning, conservation or heritage issues are involved.
