How Long Does it Take to Receive a BER Certificate After an Assessment is Completed?

As an expert in the field of building energy efficiency, I am often asked about the process of obtaining a BER certificate. This document, also known as a Building Energy Rating certificate, is a crucial component in determining the energy efficiency of a building. It provides valuable information to potential buyers or renters about the energy performance of a property, helping them make informed decisions.

What is a BER Certificate?

A BER certificate is an official document that rates the energy efficiency of a building on a scale from A to G, with A being the most efficient and G being the least efficient. It is based on the energy performance of the building's heating, ventilation, and lighting systems, as well as its insulation and air tightness.

The certificate also includes recommendations for improving the building's energy efficiency. In Ireland, it is mandatory for all buildings being sold or rented to have a BER certificate. This requirement was introduced in 2009 as part of the EU Energy Performance of Buildings Directive. The aim is to reduce carbon emissions and promote energy efficiency in buildings.

The Assessment Process

So, how long does it take to receive a BER certificate after an assessment is completed? The answer to this question depends on several factors, such as the size and complexity of the building, the availability of assessors, and the completeness of the required documentation. The first step in obtaining a BER certificate is to contact a registered BER assessor. These assessors are trained and certified by Sustainable Energy Authority of Ireland (SEAI) to carry out energy assessments and issue BER certificates.

It is important to choose an assessor who is experienced and knowledgeable in this field. Once you have chosen an assessor, they will schedule a visit to your property to carry out the assessment. During this visit, the assessor will collect information about the building's construction, insulation, heating and lighting systems, and any renewable energy sources. They will also take measurements and photographs of the building. After the assessment is completed, the assessor will use specialized software to calculate the building's energy rating. This software takes into account various factors such as the building's size, orientation, and materials used.

The assessor will also consider any improvements that have been made to the building's energy efficiency since its construction.

The Timeframe

On average, it takes about 3-5 working days for an assessor to complete the assessment and issue a BER certificate. However, this timeframe can vary depending on the complexity of the building and the availability of the assessor. In some cases, it may take longer if additional information or documentation is required. It is important to note that a BER certificate is valid for 10 years from the date of issue. If any significant changes are made to the building during this time, such as upgrades to its energy efficiency, a new assessment may be required to update the certificate.


In conclusion, obtaining a BER certificate is an essential step in promoting energy efficiency in buildings.

It provides valuable information to potential buyers or renters and encourages property owners to make improvements that will reduce their carbon footprint and save on energy costs. The timeframe for receiving a BER certificate after an assessment is completed can vary depending on several factors. However, on average, it takes about 3-5 working days. It is important to choose a qualified and experienced assessor to ensure a smooth and timely process.

So, if you are planning to sell or rent out your property, make sure to get a BER certificate to showcase its energy efficiency and attract potential buyers or renters. It is not only a legal requirement but also a step towards a more sustainable future.
