EPC for Listed Buildings in London: Rules and Exemptions

London has thousands of historic properties, from Georgian townhouses and Victorian terraces to listed mansion blocks and converted period homes. These buildings often retain original features that make them attractive to buyers and tenants.

However, their age and protected status can raise questions about Energy Performance Certificates (EPCs). Owners may wonder whether a listed building needs an EPC, whether insulation improvements are permitted and what to do before selling or renting the property.

This guide explains the main considerations for an EPC for listed buildings in London, including possible exemptions, energy-efficiency improvements and practical steps to take before arranging an assessment.

Do Listed Buildings Need an EPC in London?

A listed building is not automatically exempt from EPC requirements simply because it has historic or architectural importance.

In England, an EPC is generally required when a property is sold or rented, unless a specific exemption or other applicable exception applies.

For listed buildings, the important question is whether meeting the relevant minimum energy performance requirements would unacceptably alter the building’s character or appearance. The answer depends on the property and the proposed changes.

Therefore, owners should assess their individual circumstances rather than assuming that every listed property is exempt.

You can check the official GOV.UK guidance on Energy Performance Certificates when selling a home to understand the general requirements.

When Can a Listed Building Be Exempt from an EPC?

Some buildings protected because of their special architectural or historical merit may qualify for an exemption where compliance with minimum energy performance requirements would unacceptably alter their character or appearance.

However, listed status alone does not automatically establish that the exemption applies.

Consider these points before making a decision:

• The building’s protected features: Original windows, historic façades, decorative interiors and other significant elements may influence which improvements are acceptable.

• The proposed work: Some energy-efficiency measures may be possible without harming protected features.

• The property’s circumstances: The relevant EPC rules depend on whether the property is being sold, rented or used in another way.

• The evidence available: Owners should understand why an exemption may apply and check whether any applicable registration or documentation requirements must be met.

If you are unsure, seek advice from a suitably qualified property professional or the relevant local authority conservation team.

For official information, read the GOV.UK guidance on Energy Performance Certificates for homes.

How Do EPC Assessments Work for Historic Properties?

An EPC assessment considers the property’s relevant construction, insulation, heating, hot water and other energy-related features.

Historic buildings can have characteristics that differ from modern homes. For example, a period townhouse may have solid brick walls, original sash windows, an older boiler or limited insulation.

These features can influence the assessment, but the building’s age alone does not determine its final rating.

1. Original Windows and Glazing

Many listed properties retain traditional timber sash windows or other historic glazing.

Replacing these windows may require careful consideration because the original features could contribute to the building’s character. Depending on the circumstances, repair, draught-proofing or other suitable measures may be worth investigating.

Before making changes, check whether planning permission or listed building consent is necessary.

Do not assume that installing modern double glazing is always permitted or that it will guarantee a higher EPC rating.

2. Solid Walls and Insulation

Older London properties often have solid masonry walls rather than the cavity walls found in many newer homes.

Insulating these walls may require a different approach. Internal insulation can affect room dimensions and historic finishes, while external insulation may alter the building’s appearance.

Moisture management is also important in traditional buildings. Unsuitable insulation or installation methods can create problems if they do not account for the original construction.

Before carrying out major work, seek advice from a professional with experience in historic buildings.

3. Roofs, Lofts and Floors

Roof insulation, loft insulation and suitable floor improvements may help reduce heat loss in some historic properties.

However, the best option depends on the building’s construction and condition.

For example, a property with an accessible loft may offer different opportunities from a home with an ornate ceiling or a historic roof structure.

Review the existing EPC recommendations where available and establish which improvements are appropriate before committing to work.

4. Heating and Hot Water Systems

Some listed homes still use older boilers or traditional heating arrangements. Others have modern heating controls, upgraded boilers or alternative systems.

The assessor records the relevant features under the applicable assessment methodology.

If your property has electric heating, read our guide to how electric heating affects an EPC rating in London.

Similarly, if the property forms part of a converted period building, our guide to EPCs for converted flats in London explains additional considerations for owners.

Can You Improve the EPC Rating of a Listed Building?

Yes, some listed properties can benefit from energy-efficiency improvements. The suitable options depend on the building, its protected features and the recommendations in its EPC.

The aim should be to improve energy performance without causing unnecessary damage to historic fabric.

Consider the following steps.

Review the Existing EPC

Start by checking whether the property already has a valid certificate.

Read its rating, assessment date and recommendations. These details can help you identify areas that may need attention.

You can search for an existing certificate through the official GOV.UK Find an Energy Certificate service.

If the property has already undergone improvements, keep records of the work. A new assessment may be useful when you need an updated rating, but improvements do not automatically update an existing certificate.

Choose Suitable Improvements

Depending on the property, potential measures might include improving heating controls, upgrading an unsuitable heating system, improving insulation where appropriate or using more efficient lighting.

However, not every recommendation will suit every historic building.

Discuss significant changes with an appropriate professional, particularly where the work could affect protected features. You may need listed building consent or other permissions before starting.

For more general advice, see our guide to improving an EPC rating in London.

Keep Records of Completed Work

Maintain available documents relating to insulation, heating upgrades, window repairs and other improvements.

These records can help you explain what has changed since the previous assessment. The assessor will decide which evidence is relevant and acceptable under the applicable methodology.

What Should Landlords of Listed Properties Check?

Landlords should check the EPC requirements that apply to their property before marketing or granting a tenancy.

Where the minimum energy efficiency standards for privately rented properties apply, landlords must consider the relevant requirements and any valid exemption. Listed status should not be treated as an automatic exemption from every rental energy-efficiency obligation.

Before letting a listed property:

1. Check whether a valid EPC already exists.

2. Establish whether the property qualifies for a relevant exemption.

3. Review the current rules that apply to the intended tenancy.

4. Identify improvements that may be suitable for the building.

5. Obtain professional advice where protected features could be affected.

6. Keep relevant records of any exemption or approved work.

The official GOV.UK landlord guidance on minimum energy efficiency standards explains the rules for domestic private rented properties.

If you manage a property with several occupants, you can also read our guide to EPC requirements for HMO landlords in London. Houses in multiple occupation can have additional considerations, so check the requirements that apply to the specific property.

What Documents Should You Prepare Before an EPC Assessment?

Preparing relevant information can help make an EPC appointment more straightforward.

For a listed property, consider gathering:

• The full property address and any existing EPC.

• Details of the building’s listed status, where available.

• Records of heating and hot water installations.

• Information about insulation or energy-efficiency improvements.

• Records of window repairs or replacements.

• Relevant building plans or documentation.

• Details of alterations that may affect the property’s construction.

You do not necessarily need every document on this list. The information required depends on the property and the details the assessor needs to establish.

For further preparation advice, read our guide to EPC documents needed when selling or renting in London.

If you are preparing the property for sale, our EPC checklist before marketing a property in London may also be useful.

Does a Listed Building Need a New EPC After Renovation?

Not every renovation automatically requires a new EPC.

An existing certificate is generally valid for 10 years unless a newer certificate replaces it. However, if you have made substantial energy-efficiency improvements, a new assessment may help show the property’s updated performance when selling or renting.

The correct approach depends on the work completed and your circumstances.

For example, replacing a boiler or improving suitable insulation may change the property’s energy performance. However, the existing EPC rating will not update automatically.

Before arranging another assessment, check the certificate’s validity and consider whether you need a new rating for your property plans.

Our guide to how long an EPC remains valid in London explains the general validity period.

How Much Does an EPC Cost for a Listed Building in London?

The cost depends on the property, the assessor and the service required.

A listed building does not automatically cost more to assess simply because it is historic. However, an unusual layout, multiple dwellings or access considerations may be worth discussing before booking.

Ask for a clear quotation based on the property details. You should also confirm that the assessor is appropriately accredited for the assessment required.
