A Building Energy Rating (BER) Certificate measures the energy efficiency of a property in Ireland. Issued by a registered SEAI BER assessor, it rates a building from A1 (most energy efficient) to G (least energy efficient). The certificate also estimates energy consumption, carbon emissions and provides recommendations to improve the property's energy performance.

Yes. Under Irish law, most residential properties must have a valid BER Certificate before they are advertised for sale. The BER rating must also be included in all property advertisements.

Yes. Landlords must provide a valid BER Certificate when renting out a property in Ireland. The BER rating should be available to prospective tenants before the tenancy begins.

Getting a BER Certificate is simple with Monread Engineering.

1. Book your BER assessment with our registered SEAI BER Assessor.
2. We visit your property to assess key energy efficiency features, including insulation, heating systems, windows, ventilation, lighting and renewable energy installations.
3. Your property's details are assessed using SEAI-approved BER software to calculate its official Building Energy Rating.
4. Your BER Certificate and Advisory Report are then issued and registered on the national SEAI BER database, ready for use when selling, renting or upgrading your property.

The duration of a BER assessment typically ranges from 1 to 3 hours, depending on the size and complexity of the property. The assessor will need full access to all areas of the building.

A BER rating is calculated using the Dwelling Energy Assessment Procedure (DEAP) developed by the Sustainable Energy Authority of Ireland (SEAI). The assessment considers factors including:

• Insulation levels
• Wall, roof and floor construction
• Windows and doors
• Heating system efficiency
• Hot water system
• Ventilation
• Renewable energy technologies
• Lighting

You can find more information on the calculation process on the official SEAI website here.

Improving insulation, upgrading to a more efficient heating system, installing double or triple glazing, and integrating renewable energy sources like solar panels are common ways to enhance a property's BER rating.

A BER Cert is valid for 10 years, unless significant energy upgrades are carried out to the property, in which case a new assessment is recommended.

Yes. BER Certificates expire 10 years after they are issued. If you are selling or renting your property after this period, you'll need a new BER assessment.
