Do Listed Buildings
Need an EPC?

When listed buildings need EPCs plus when they do not

The widespread belief that all listed buildings are exempt from EPC rules is wrong. The actual exemption is narrower than most owners assume plus depends on a character impact test, not on listed status itself.

The legal basis. Regulation 5(1)(a) of the Energy Performance of Buildings (England plus Wales) Regulations 2012 exempts officially protected buildings (listed buildings plus buildings within a conservation area) from EPC requirements only where compliance with minimum energy performance requirements would unacceptably alter their character or appearance.

What unacceptably alter character means in practice. Energy efficiency improvements for an EPC do not require physical changes to the building. They can be entirely advisory. The exemption only applies if implementing the recommendations would unacceptably alter character. Most loft insulation, secondary glazing plus boiler upgrades do not unacceptably alter listed building character. External wall insulation, replacement windows plus solar panels often do.

What this means for listed building owners:

• Most Grade II listed homes (the largest category by far) still need EPCs when selling or renting. The recommendations on the EPC are advisory not mandatory.
• Grade I plus Grade II* listed buildings have stricter character protection but still often need EPCs. The exemption depends on whether compliance would damage character, not on the grade itself.
• Buildings in conservation areas (not necessarily listed themselves) are subject to the same character test.
• Holiday lets plus commercial listed buildings have separate rules under the same regulation.

Practical guidance:

• Check whether your building is listed by searching the National Heritage List for England (NHLE) at HistoricEngland.org.uk. Wales uses Cadw.
• If listed, contact the local authority conservation officer to discuss whether EPC compliance would damage character.
• Document the exemption decision in writing. Keep records of advice received plus reasons for exemption.
• If marketing the property for sale or let, expect estate agents to ask for the EPC. Provide the documented exemption case if claiming exemption.
• For rentals, exemptions to MEES Regulations 2015 (the EPC E minimum rule) must be registered on the PRS Exemptions Register separately from EPC requirement exemptions.

Common improvements that do not unacceptably alter character:

• Loft insulation in unused roof spaces.
• Underfloor insulation in solid floors not visible from inside.
• Secondary glazing fitted internally behind original windows.
• Heating system upgrades when boiler plus pipework are not visible.
• Energy-efficient lighting in modern fittings.
• Improved heating controls plus thermostats.

Common improvements that may unacceptably alter character:

• External wall insulation that changes building appearance.
• Replacement double-glazed windows in original frames.
• Visible solar panels on principal elevations or visible roof slopes.
• Modern heating ducts or visible flue pipes.
• Replacement of historic features with modern energy-efficient equivalents.

Listed building consent. Even where an EPC is not required because of the character test, any physical alteration to a listed building still requires Listed Building Consent from the local authority. EPC exemption is separate from listed building consent rules. Always consult the conservation officer before making physical changes.

Listed building EPC exemption is one of the more nuanced areas of the rules. Our full EPC Ratings hub covers Energy Performance Certificates plus MEES regulations across UK homes plus rental properties.
