Energy Certificate

What Is It?

The Energy Certificate (Certificado Energético) is an official document that assesses a property’s energy efficiency on a scale from A+ (highly efficient) to F (low efficiency).

It is issued by qualified experts accredited by ADENE (Agência para a Energia), Portugal’s national energy agency.

What Is It For / Why Is It Important?

Legal Requirement
The certificate is mandatory by law to:

• advertise a property for sale or rent,

• complete the final deed (Escritura), and

• sign a rental agreement.

Consumer Information
Provides an estimate of energy and water consumption and includes recommendations to improve efficiency and reduce utility costs (such as insulation upgrades or double-glazed windows).

Financial and Tax Advantages
Properties rated A or A+ may benefit from IMI reductions or access to preferential mortgage conditions, often referred to as Green Mortgages.

Where Can You Obtain It?

The certificate must be issued by a Qualified Energy Expert (Perito Qualificado).

The professional:

• visits the property,

• collects measurements and technical data,

• performs energy calculations,

• and issues the digital certificate through the national certification system (SCE — Sistema de Certificação Energética).

The official list of certified experts is available via ADENE.

What Does It Cost?

Costs usually include two components:

ADENE Registration Fee (Fixed)
Approximately €28 to €65 for residential properties, depending on typology (from T0 to T6+), plus VAT.

Expert’s Professional Fee (Variable)
Typically between €100 and €250, depending on property size, complexity, and location.

Validity

• Residential properties: 10 years

• Commercial or service buildings: generally 10 years (or 8 years in specific cases involving large technical systems)

Important: Fines

Advertising a property without displaying its energy rating may result in administrative fines ranging from approximately €250 to €3,740 for private owners.
