How Long Is an EPC Valid in London? A Complete Guide
If you own, sell or rent out a property in London, you may already have an Energy Performance Certificate (EPC). But do you know how long it remains valid?
So, how long is an EPC valid?
In most cases, an EPC is valid for 10 years from the date it was issued. However, there are situations where you may need to check your certificate sooner, particularly if a newer EPC has been issued or you are preparing to sell or rent your property.
Understanding your EPC expiry date can help you avoid unnecessary costs and last-minute delays.
How Long Is an EPC Valid?
An EPC is generally valid for 10 years from its date of issue.
For example, if your EPC was issued in October 2026, it would normally remain valid until October 2036 unless it is replaced by a newer EPC.
You do not normally need to arrange a new EPC simply because a property changes ownership or a new tenant moves in.
However, you should always check the certificate before marketing a property for sale or rent.
You can search for an existing certificate through the official GOV.UK Find an Energy Certificate service.
Does an EPC Automatically Expire After 10 Years?
Yes.
Once the 10-year validity period has ended, the EPC is no longer current.
If you are planning to sell or rent the property and an EPC is required, you may need to arrange a new assessment before marketing.
It is better to check the expiry date early rather than discovering that your certificate has expired when your property is ready to be advertised.
Does a New EPC Replace an Old EPC?
Yes.
If another EPC is produced for the same property, the newer certificate can replace the previous one.
This can happen when a property owner decides to obtain a new assessment after making improvements.
For example, you may have:
Installed a more efficient boiler
Added loft or wall insulation
Replaced windows
Improved heating controls
Installed solar panels
Made other energy-efficiency improvements
Your existing EPC does not automatically update when these changes are made.
If you want the property’s current energy performance to be reflected in a new certificate, another EPC assessment is required.
Do You Need a New EPC When Selling a London Property?
Not necessarily.
If your existing EPC is still valid, you may not need a new certificate simply because you have decided to sell your property.
However, you should check your EPC before putting the property on the market.
Where an EPC is required, GOV.UK guidance states that it should generally be available before a property is marketed.
If you are selling a London property, you can also read our guide on EPC requirements when selling a property in London.
Checking your certificate early can prevent unnecessary delays during the sales process.
Do You Need a New EPC When Renting?
A new tenant does not automatically mean that you need a new EPC.
If the property already has a valid certificate and continues to meet the applicable requirements, the existing EPC may still be used.
However, landlords should check the certificate’s validity and the current rules before advertising a property for rent.
This is especially important if your EPC is approaching its expiry date.
How Can You Check Your EPC Online?
You do not necessarily need to contact the previous owner or landlord to find out whether an EPC exists.
The official government service allows you to search for an EPC online.
You can use the GOV.UK Find an Energy Certificate service to search for your property’s certificate.
Depending on the information available, you may be able to search using:
Postcode
Street name
Town
Certificate number
Once you find the certificate, check its issue date and expiry date.
You can also review the property’s energy rating and recommendations.
What Does an EPC Tell You?
An EPC gives an indication of a property’s energy performance.
The certificate uses an energy efficiency rating from A to G, with A representing the highest efficiency rating.
An EPC can also provide information about areas such as:
Heating
Hot water
Insulation
Windows
Lighting
Energy use
Potential energy improvements
The recommendations can help property owners understand where energy-efficiency improvements may be possible.
However, an existing EPC does not automatically change when you make improvements.
Should You Get a New EPC After Improving Your Property?
Making improvements does not automatically update your existing EPC.
For example, imagine that your property currently has a D rating.
You then replace the heating system, improve insulation and install more efficient windows.
Your existing certificate will still show the rating recorded when that EPC was produced.
If you want the property’s updated energy performance to be recorded, you can arrange a new EPC assessment.
Before investing in improvements, it is worth reviewing your existing EPC recommendations and considering which improvements are appropriate for your property.

Does an EPC Last the Same Amount of Time for Flats?
Yes, the standard EPC validity period is generally 10 years for residential properties, including flats.
However, flats can have different EPC considerations depending on how the property is structured and assessed.
If you own or manage a flat in London, our recent guide EPC for Flats London: What Flat Owners Need to Know provides more information about EPC considerations for flats.
What If Your Property Is an Older London Home?
The age of your property does not normally change the standard EPC validity period.
An older property can still have an EPC that is valid for 10 years.
However, older buildings can have different construction characteristics that affect their energy performance.
For example, a period property may have:
Solid walls
Older windows
Traditional construction
Limited insulation
Older heating systems
Extensions or alterations
If you own an older London property, it is useful to understand how these features may affect an EPC assessment.
What Should You Do Before an EPC Appointment?
If your existing EPC has expired and you need a new assessment, preparing the property beforehand can make the appointment easier.
Have relevant information available about:
Heating systems
Boiler
Insulation
Windows
Hot water system
Renewable energy systems
Recent improvements
If you are also arranging photography or a floor plan, you may be able to coordinate the appointments.
Our guide How to Prepare for an EPC, Photography and Floor Plan Appointment in London explains how property owners can prepare before these appointments.
Does a Renovation Mean You Need a New EPC?
Not every renovation automatically requires a new EPC.
Replacing windows, improving insulation or upgrading a heating system does not necessarily mean that an existing certificate immediately becomes invalid.
However, more significant building alterations can create different EPC requirements.
For example, certain modifications that create more or fewer separately used parts of a building, together with relevant fixed building services, can affect EPC requirements.
For substantial conversions or structural alterations, it is important to check the applicable requirements rather than assuming that your existing EPC covers the changed property.
What About Property Licensing?
EPC requirements can sometimes form part of a wider property compliance process.
If you are preparing a property for licensing, you may also need appropriate floor plans and other documentation.
Our recent guide Floor Plan for Selective Licence in London: What to Include explains what a floor plan may need to show when preparing for selective licensing.
You can also read Floor Plan for Property Licensing in London: What to Include for more information about floor plans and property licensing.
What Documents Should You Keep?
Keeping records of improvements can be useful when arranging future property assessments.
Consider keeping copies of:
Boiler installation documents
Window replacement information
Insulation records
Heating system documents
Solar panel information
Product specifications
Installation certificates
Relevant invoices
Guarantees
Building work documents
Having this information available can make it easier to provide accurate details about the property.
If you are preparing a property for sale or rent, our guide EPC Documents You Need When Selling or Renting in London covers useful documentation to consider.
When Should You Arrange a New EPC?
You should not wait until the day your property is due to be marketed.
If your EPC is approaching its expiry date and you are planning to sell or rent, check the current requirements and arrange a new assessment if necessary.
This is particularly useful if you are preparing several aspects of the property at the same time.
For example, you may need to organise:
EPC
Photography
Floor plan
Property description
Marketing materials
Licensing documents
Other property certificates
Preparing these items early can help reduce delays.

Final Thoughts
So, how long is an EPC valid?
For most properties, an EPC is generally valid for 10 years from its issue date.
You do not normally need a new EPC simply because you are selling the property, changing tenants or carrying out ordinary improvements.
The best approach is to check your existing certificate first.
Look at the issue and expiry dates, confirm that it relates to the correct property and check whether a newer certificate has already been issued.
If your EPC has expired, or you need an updated assessment after changes to the property, you may need to arrange a new EPC.
