Yes — in most cases, flats and apartments require their own separate Domestic EPC in 2026.

Even if the building has multiple units, each self-contained dwelling that is sold or rented must have an individual Energy Performance Certificate.

Here’s how it works.

What Is the Legal Requirement?

Under regulations set by the UK Government:

  • Every self-contained residential unit requires its own EPC

  • The EPC must be available before marketing

  • Domestic EPCs remain valid for 10 years

This means a flat within a block cannot rely solely on a building-level certificate (in most cases).

What Counts as a “Self-Contained” Flat?

A flat or apartment is considered self-contained if it has:

  • Its own kitchen

  • Its own bathroom

  • Separate heating and energy supply

  • Independent access

If these conditions are met, a separate EPC is required.

Can One EPC Cover the Whole Building?

Generally, no — for residential blocks.

However, limited exceptions may apply:

  • Identical flats built to the same design and heating system

  • Certain conversions with shared systems

  • Student accommodation in specific circumstances

In practice, estate agents and solicitors will expect an EPC for the specific unit being sold or rented.

What About Shared Heating Systems?

Even if a building uses:

  • Communal boilers

  • District heating

  • Shared energy systems

Each flat still requires its own EPC because:

  • Floor area differs

  • Orientation differs

  • Heat distribution differs

  • Insulation levels may vary

The rating is calculated individually using SAP methodology.

Do Leasehold Flats Follow Different Rules?

No. Leasehold status does not remove the EPC requirement.

If you are:

  • Selling a leasehold flat

  • Letting a leasehold apartment

You must provide a valid EPC.

If letting, the property must also comply with the Minimum Energy Efficiency Standards (MEES), meaning it must be rated E or above unless exempt.

What If the EPC Has Expired?

If your flat’s EPC has expired:

  • You cannot market it legally without renewing

  • The certificate must be available to buyers or tenants

Do Studio Apartments Need an EPC?

Yes. Studio flats are still self-contained dwellings and require a valid EPC before sale or rental.

Final Answer

✔ Yes — flats and apartments require a separate EPC in 2026.
✔ Each self-contained unit must have its own certificate.
✔ Building-level EPCs usually do not replace individual unit certificates.
✔ Rental flats must meet EPC E minimum under MEES.

If you’re planning to sell or let a flat, arranging your EPC early avoids marketing delays.
