Leasehold flats make up a significant proportion of London’s residential property market. From modern developments in Canary Wharf and Nine Elms to Victorian conversions in Islington, Greenwich and Clapham, many property owners, landlords and investors own leasehold apartments.

When selling, renting or managing a leasehold property, Energy Performance Certificates (EPCs) remain an important part of the process. However, leasehold flats often present unique considerations that differ from freehold houses.

Understanding how EPC assessments apply to leasehold properties can help owners make more informed decisions regarding property management, refurbishment projects and long-term investment planning.

Do Leasehold Flats Need an EPC?

In most cases, yes.

Leasehold flats typically require a valid EPC when being marketed for sale or rent.

This includes:

  • Purpose-built apartments.
  • Modern city flats.
  • Victorian conversions.
  • Maisonettes.
  • Shared ownership properties.

The EPC provides information about the property’s energy performance and includes a rating from A (most efficient) to G (least efficient).

Why Leasehold Flats Are Different

Unlike freehold houses, leasehold owners often have limited control over certain parts of the building.

This can include:

  • External walls.
  • Roof structures.
  • Communal heating systems.
  • Shared hallways.
  • Communal lighting.
  • Building-wide improvements.

These factors can influence both renovation planning and future energy efficiency improvements.

Communal Heating Systems and EPC Assessments

Many London apartment blocks operate communal or district heating systems.

These arrangements can create additional assessment considerations because individual flat owners may not have direct control over the heating infrastructure.

Where communal systems exist, supporting information and building records may be particularly important.

Can Leasehold Restrictions Affect Energy Improvements?

In many cases, yes.

Lease agreements may restrict certain alterations or require management company approval before work is undertaken.

Examples may include:

  • Window replacement.
  • External insulation works.
  • Renewable technology installations.
  • Building fabric alterations.

Property owners should always review lease conditions and obtain any necessary approvals before undertaking major works.

Supporting Evidence Is Particularly Important

Many leasehold flat owners complete improvements over time but do not retain supporting documentation.

Examples of useful evidence may include:

  • FENSA certificates.
  • Building Control approvals.
  • Insulation certificates.
  • Heating installation records.
  • Manufacturer specifications.
  • Management company documentation.

Suitable evidence may help ensure qualifying features are appropriately reflected where assessment methodologies and conventions allow. See our full guide to EPC evidence and documents.

Leasehold Flats and Property Refurbishment

Many landlords and investors purchase leasehold flats that require refurbishment.

Typical projects may include:

  • Kitchen upgrades.
  • Bathroom renovations.
  • Heating improvements.
  • Window replacements.
  • Energy efficiency upgrades.

Before investing significant amounts, many property owners wish to understand how those improvements fit within the property’s overall energy profile — our guide to EPCs before renovation covers the planning stage in detail.

Why Consider a Draft EPC Before Renovating a Leasehold Flat?

Leasehold properties often involve additional restrictions and considerations that are not always present in freehold houses.

A Draft EPC review can help property owners:

  • Review current energy performance.
  • Identify relevant supporting evidence.
  • Explore potential improvement pathways.
  • Support budgeting decisions.
  • Assist with refurbishment planning.

For example, a landlord planning a major refurbishment may wish to understand what options are realistically available within the constraints of the lease before committing expenditure.

A Draft EPC can support this planning process.

However, a Draft EPC does not guarantee a particular EPC rating, compliance outcome or improvement result.

Final EPC ratings depend on the property’s characteristics, supporting evidence, assessment methodology and information available at the time of the official assessment.

Leasehold Flats and Buy-to-Let Investment

Leasehold apartments are popular among London property investors.

Investors often consider:

  • Location.
  • Rental demand.
  • Service charges.
  • Lease length.
  • Property condition.
  • Energy performance considerations.

Understanding the property’s current EPC position can help support long-term investment planning.

Mortgages, Remortgages and Leasehold Flats

Many leasehold property owners review their EPC status when:

  • Selling a flat.
  • Purchasing a property.
  • Applying for a mortgage.
  • Applying for a remortgage.
  • Completing refurbishment works.

Where significant improvements have been completed, owners may choose to commission a new EPC to obtain a more current assessment.

Purpose-Built Flats vs Converted Flats

Leasehold flats vary significantly across London.

Purpose-built apartments often benefit from:

  • Modern construction standards.
  • Improved insulation.
  • Contemporary heating systems.
  • Energy-efficient glazing.

Converted flats may have very different construction characteristics depending on the age and history of the building.

Each property should be assessed individually.
