Improving Your BER Rating: Expert Tips for a Better BER Certificate

As an expert in the field of energy efficiency, I have seen firsthand the importance of having a good BER certificate. A Building Energy Rating (BER) certificate is a document that shows the energy performance of a building on a scale from A to G, with A being the most efficient and G being the least efficient. It is required for all buildings being sold or rented in Ireland, and having a good rating can greatly benefit both homeowners and tenants.

Why is a Good BER Rating Important?

A good BER rating not only reflects positively on the energy efficiency of a building, but it also has several other benefits. For homeowners, it can increase the value of their property and make it more attractive to potential buyers.

It also means lower energy bills, as a more efficient building requires less energy to heat and cool. For tenants, a good BER rating means lower utility costs and a more comfortable living space. But what if your BER rating is not as good as you would like it to be? Are there ways to improve it? The answer is yes! In this article, I will share some expert tips on how you can improve your BER rating and get a better BER certificate.

1.Insulate Your Home

One of the most effective ways to improve your BER rating is by insulating your home. Proper insulation helps to keep heat inside during the winter and outside during the summer, reducing the need for heating and cooling. This can greatly improve the energy efficiency of your home and result in a better BER rating. There are several types of insulation available, such as cavity wall insulation, attic insulation, and external wall insulation.

It is important to choose the right type for your home and have it installed by a professional to ensure maximum effectiveness.

2.Upgrade Your Heating System

The type of heating system you have in your home can also have a significant impact on your BER rating. Older, inefficient systems can greatly decrease your rating, while newer, more efficient systems can improve it. If your heating system is over 15 years old, it may be time to consider upgrading to a more energy-efficient option. Some examples of energy-efficient heating systems include heat pumps, solar panels, and condensing boilers. These systems use less energy to heat your home, resulting in a better BER rating and lower energy bills.

3.Install Energy-Efficient Windows and Doors

Windows and doors are another important factor in determining your BER rating.

Old, single-glazed windows and poorly insulated doors can result in significant heat loss, which can greatly affect your rating. By upgrading to energy-efficient windows and doors, you can improve the insulation of your home and reduce heat loss. Energy-efficient windows and doors are designed to keep heat inside during the winter and outside during the summer. They are also better at reducing noise pollution and improving the overall comfort of your home.

4.Use Energy-Efficient Appliances

The appliances you use in your home also play a role in your BER rating. Older appliances tend to be less energy-efficient, which can negatively impact your rating.

By replacing them with newer, more energy-efficient models, you can improve your rating and save money on your energy bills. When shopping for new appliances, look for the EU Energy Label, which rates appliances from A+++ (most efficient) to D (least efficient). Choosing appliances with a higher rating can greatly improve the energy efficiency of your home.

5.Consider Renewable Energy Sources

Using renewable energy sources is not only good for the environment, but it can also improve your BER rating. Solar panels, for example, can generate electricity for your home, reducing your reliance on traditional energy sources. This can result in a better BER rating and lower energy bills. Other renewable energy sources to consider include wind turbines and heat pumps.

These options may require a larger upfront investment, but they can greatly improve the energy efficiency of your home in the long run.

6.Get a BER Assessment

If you are unsure about the energy efficiency of your home, it may be beneficial to get a BER assessment. A qualified BER assessor will evaluate your home and provide you with a detailed report on its energy performance. This report will also include recommendations on how you can improve your BER rating. It is important to note that a BER assessment is required when selling or renting a property in Ireland, so it is best to get one done before putting your home on the market.


A good BER rating is not only important for meeting legal requirements, but it also has several benefits for homeowners and tenants. By following these expert tips, you can improve your BER rating and get a better BER certificate.

Not only will this result in lower energy bills, but it will also make your home more attractive to potential buyers or tenants. Remember, small changes can make a big difference when it comes to energy efficiency. So take the necessary steps to improve your BER rating and enjoy the benefits of a more efficient home.
