What is required today
A valid Spanish energy performance certificate—Certificado de Eficiencia Energética—is required when an eligible property is offered for sale or rent. The certificate gives the building an A–G rating and must be made available to the buyer or tenant.

What the revised EU directive says
Directive (EU) 2024/1275 sets a national trajectory for residential buildings. Member States must reduce the average primary energy use of their residential building stock by at least 16% by 2030 and 20–22% by 2035, with substantial reductions coming from the worst-performing buildings.

What it does not say
The European Commission states that the directive does not impose a renovation obligation on individual homeowners. It does not currently create an EU-wide rule preventing an individual home rated E, F or G from being sold or rented. Spain’s detailed implementation may evolve, so property owners should follow official updates.

Why plan improvements now
Regardless of future thresholds, reducing heat gain and loss, improving systems and generating solar electricity can improve comfort, reduce reliance on bought energy and support a stronger EPC result. A property-led plan avoids replacing systems in the wrong order.
