Note: This is a general guide for UK commercial property owners and professionals. Non-domestic EPC regulations, registers and processes differ across England & Wales, Scotland and Northern Ireland. Always check the current position on GOV.UK and the relevant national register before acting on any specific matter.
Two regimes in one building
Where a building combines commercial and residential use, the residential dwellings are assessed under the domestic methodology and the commercial parts under the non-domestic methodology. A single certificate does not cover both.
Shared services
Communal plant serving both uses has to be apportioned sensibly between the assessments. Access to riser and plant room drawings is usually the deciding factor in how straightforward this is.
Common scenarios
Shop with flats above, office conversions with retained ground-floor retail, and pubs with residential accommodation are the typical cases. Each usually results in one non-domestic EPC plus separate domestic EPCs per dwelling.
