EPBD Directive 2024/1275 · Mandatory milestones
Portugal's Energy Compliance Timeline
The EPBD creates hard deadlines that affect the value, rentability, and saleability of every property you buy today.
You are here - 2026
Jan 2026
Class G rental restrictions begin
Class G properties may no longer be offered for new rental contracts. Existing tenancies are unaffected but renewals are restricted. Already in force.
2030
Class F & G face sale restrictions
Properties rated F or G will face restrictions on resale. A property you buy today at Class F becomes significantly harder to sell from 2030 onward without a completed retrofit.
2033
All properties must reach minimum Class D
The hard deadline. Every residential property in Portugal must achieve a minimum Class D energy rating. Properties below this threshold face legal restrictions on both rental and sale.
