One of the most common questions asked by landlords, leaseholders, property investors and estate agents is whether each apartment or flat requires its own Energy Performance Certificate (EPC).
EPCRATE Services — Quick Links
The answer depends on how the property is arranged, whether the units are self-contained and how they are being marketed or occupied. Understanding EPC requirements for flats and apartments can help property owners remain compliant and avoid delays when selling, renting or managing residential property.
Founded in 2015 by Jino Jose, EPCRATE has helped landlords, homeowners, estate agents and property investors across London obtain professional EPC assessments, with same-day appointments available where possible. Call 020 3488 4142 to book.
What Is an EPC?
An Energy Performance Certificate measures the energy efficiency of a property and provides a rating from A (most efficient) to G (least efficient).
The certificate includes:
- Current energy efficiency rating.
- Potential future rating.
- Estimated energy performance information.
- Carbon emissions data.
- Recommended energy efficiency improvements.
Domestic EPCs generally remain valid for 10 years from the date they are issued.
Does Every Flat Need Its Own EPC?
In many circumstances, yes.
Where a flat or apartment is a self-contained residential unit, a separate EPC is typically required when the property is being marketed for sale or rent.
This applies whether the flat is:
- Leasehold.
- Freehold.
- Owner occupied.
- Privately rented.
- Part of a larger building.
Each self-contained dwelling is generally assessed individually using approved assessment methodologies. For buy-to-let landlords managing multiple units, our buy-to-let EPC guide covers portfolio requirements in detail.
What Is a Self-Contained Residential Unit?
A self-contained residential unit is generally a property where occupants have exclusive use of the accommodation and essential facilities.
This commonly includes:
- Private kitchen facilities.
- Private bathroom facilities.
- Independent living accommodation.
Many flats and apartments throughout London fall into this category.
Do Flats in Apartment Blocks Need Separate EPCs?
In many cases, individual flats within apartment blocks require separate EPCs because each dwelling is treated as its own residential unit.
Even if all apartments are located within the same building, separate assessments are often required where individual properties are being sold or rented.
This applies to:
- Modern apartment developments.
- Purpose-built blocks.
- Mixed-use residential buildings.
- Private residential schemes.
What About Converted Houses?
Many London properties have been converted from single houses into multiple flats.
Where the converted units are self-contained dwellings, separate EPC requirements commonly apply.
Examples include:
- Victorian house conversions.
- Edwardian property conversions.
- Period townhouse conversions.
- Converted residential buildings.
Each flat is generally assessed based on its own characteristics and energy performance.
Do HMOs Need Separate EPCs?
Houses in Multiple Occupation (HMOs) can sometimes create confusion.
Requirements depend on how the property is arranged and occupied.
Where a building functions as a single dwelling with multiple occupants sharing facilities, different EPC considerations may apply compared with a building divided into self-contained flats.
Property owners should review current government guidance and seek professional advice where appropriate. Landlords operating HMOs in London boroughs with selective licensing schemes should also be aware that a valid EPC may be required as part of the landlord licensing application.
Do Studio Flats Need Their Own EPC?
Yes, in many circumstances.
A studio apartment that functions as a self-contained residential unit will commonly require its own EPC when being marketed for sale or rent.
The fact that the property is a studio rather than a larger flat does not necessarily remove the requirement.
Do Leasehold Flats Require EPCs?
Leasehold status does not normally remove EPC requirements.
Many London flats are leasehold properties and commonly require valid EPCs when marketed for sale or rent.
This includes:
- Purpose-built apartments.
- Luxury developments.
- Converted flats.
- Shared ownership properties.
- Private residential schemes.
Can One EPC Cover Multiple Flats?
In many situations, separate self-contained flats require separate EPCs.
However, every building arrangement is different.
The appropriate approach depends on the property’s layout, use and how individual units are configured.
Property owners should ensure they review the latest guidance applicable to their specific building arrangement.
Why EPCs Matter for Flat Owners and Landlords
EPCs provide useful information for:
- Prospective buyers.
- Tenants.
- Mortgage lenders.
- Estate agents.
- Property managers.
They help demonstrate energy performance and can form part of the overall property marketing and compliance process.
What Happens During an EPC Assessment?
The EPC assessment process is straightforward and non-invasive.
During the inspection, the assessor records information relating to:
- Property dimensions.
- Wall construction.
- Roof construction.
- Heating systems and controls.
- Hot water systems.
- Glazing.
- Fixed lighting.
- Insulation where supporting evidence is available.
Supporting documentation such as insulation certificates, FENSA certificates and Building Control records may help ensure qualifying features are recognised appropriately. EPCRATE typically lodges the certificate within 24 hours of the assessment.
