What Is Building Energy Rating (BER)?

BER is the acronym for A Building Energy Rating. It shows the energy performance of your home through a BER report, which also includes recommendations for improvements. The efficiency of your home’s energy is rated on a scale of A – G, with A being the most efficient and G being the least efficient. 

The higher your BER, the more efficient your energy consumption. For instance, an A-rated house conserves the heat better. Hence, the amount of fuel consumed is also lower. In short, A-rated homes will benefit from low energy costs, while G-rated homes will attract high energy bills.

TIP: As renowned solar installers Darwin, we always recommend aiming for a B2 rating, while planning for home energy upgrades. This gives you the most savings out of your investment by reducing heat loss.

Why Do You Need One?

Any home which is put up for sale or rent in Ireland requires a BER certificate and details to be included in the advertisement when the property is on the market.  

Since January 2013, it has been made compulsory for all homes, especially new dwellings, to ensure they are built with energy-efficient designs, materials and appliances that are in line with the Government’s Sustainable Energy Policy. 

It is the responsibility of the homeowner to arrange for a BER assessment. With that said, if you are planning to upgrade your home’s energy efficiency level, the SEAI suggests starting with a BER assessment. This will help you understand where your property stands on an A – G efficiency scale, and you can determine to upgrade your priorities accordingly.

How Do You Get One?

To get your residential BER certificate, you need to get an assessment from SEAI-registered BER assessors. Experienced solar installers Darwin of One Roof Solar can help you. 

They will come to your property and conduct a survey (which typically takes about an hour ) to ascertain how much energy your residence requires for heating and lightning. 

After the assessment, you will be provided with a BER Certificate and an Advisory Report. 

How Long Is a BER Certificate Valid?

A BER certificate is valid for 10 years, provided there are no major modifications or alterations to your home that could affect the energy performance. New properties sold off-plan can get provisional BER certificate based on the home design – which is valid for two years.

How to Improve Your Residential BER?

Improving the Building Energy Rating (BER) of your home will increase comfort, reduce your energy and heating costs and even increase the resale value of your property. Additionally, it will help you reduce your carbon footprint.

Tips To Improve Your BER

OneRoof Solar, your trusted residential solar installation company in Darwin, suggests making the following changes in your home to witness an improved BER:

  1. Replace or Seal old Windows

Heat loss from old, inefficient windows and glazing is common. Draught stripping can help with this, but replacing all windows or installing energy-efficient glazing will be a better option and yield the highest overall savings. 

  1. Choose Low Energy Lightening 

If you want to see a noticeable difference in your electricity bills, replace old inefficient bulbs with low-energy LED lights.


  1. Check your Ventilation

Install chimney balloons in your fireplace and encourage better airflow. This not only helps reduce drought but also helps keep the heat in when it is not in use. 


  1. Get a Lagging Jacket 

Get your hot water cylinder a lagging jacket. This will keep the water warmer for longer, save money and improve your BER rating.
