Why it still matters
The revised timetable gives assessors, developers and property businesses more time to prepare, but the change to five-year certificates will affect how often buildings need to be reassessed.
Who this affects
Energy assessors, developers, landlords, estate agents, building owners and firms involved in energy-efficiency work.
What to do now
- Plan around 30 April 2028, but remember that the date still needs Scottish Parliament approval.
- Check whether an existing EPC can be used during the transition instead of assuming it must be replaced immediately.
- Developers completing a building on or after the start date should allow for the new EPC and property-report requirements.
What will change?
Domestic EPCs will show separate ratings for heat retention, the heating system and energy costs. Non-domestic certificates will cover energy performance, energy use and direct emissions. New certificates will remain valid for five years rather than ten.
The Scottish Government also plans a new accreditation system for assessors. The regulations and start date remain subject to approval by the Scottish Parliament.
How will the changeover work?
From 30 April 2028, assessors will issue only the new-style certificate. For most buildings being sold or let, an existing certificate can still be used during a one-year transition. From 30 April 2029, only the new-style EPC and property report will meet the requirement.
A building completed on or after 30 April 2028 will need a new-style EPC and property report. The developer must give both to the owner within seven days of submitting the completion certificate to the council.
What to do now
There is no need to replace every current EPC early. Firms should update their advice, forms and project programmes once the regulations are approved, and check the transition rules against each property rather than relying on the headline date.
