What is a BER certificate?

A Building Energy Rating (BER) certificate shows how energy-efficient a property is, using a scale from A (most efficient) to G (least efficient).

It also includes an advisory report outlining recommended improvements to improve energy performance.

Is a BER certificate legally required in Ireland?

Yes. In most cases, a valid BER certificate is legally required when selling or renting a residential or commercial property in Ireland.

The BER rating must also be displayed in property advertisements.

Who needs a BER certificate?

A BER certificate is required by:

  • Homeowners selling a property

  • Landlords renting a property

  • Estate agents advertising properties

  • Property owners applying for certain SEAI grants

Some exemptions apply, but most occupied buildings require a BER.

How long does a BER certificate last?

A BER certificate is valid for 10 years, unless significant energy upgrades are made to the property, such as insulation improvements or heating system upgrades.

How much does a BER certificate cost?

The cost of a BER certificate depends on factors such as:

  • Property size

  • Property type (house, apartment, commercial)

  • Complexity of the building

How is a BER assessment carried out?

A BER assessment involves an on-site inspection by an SEAI-registered BER assessor. The assessor examines elements such as:

  • Insulation

  • Windows and doors

  • Heating and hot water systems

  • Ventilation

  • Lighting and building layout

The collected data is entered into SEAI-approved software to generate the BER certificate.

How long does a BER assessment take?

Most on-site BER assessments take between 45 minutes and 2 hours, depending on the size and complexity of the property.

How quickly will I receive my BER certificate?

In most cases, BER certificates are issued shortly after the on-site assessment, once all data has been verified and submitted to SEAI.

Can I improve my BER rating?

Yes. Common ways to improve a BER rating include:

  • Upgrading insulation

  • Improving heating efficiency

  • Installing heating controls

  • Adding renewable energy systems

Improving your BER rating can reduce energy bills, improve comfort, and increase property value.

Is a BER certificate required for SEAI grants?

A BER certificate is often required when applying for SEAI home energy grants.

It helps assess eligibility and measure improvements after works are completed.

Do I need to prepare anything before the assessment?

If available, it’s helpful to have:

  • Details of insulation upgrades

  • Information on heating systems

  • Documentation for recent energy improvements

However, if documentation is not available, the assessor can still complete the assessment based on inspection and evidence.
