10 ways to improve your house BER rating

Published 20th May 2022Read Time 6 min

If your home’s BER has not been a priority, it certainly will be now with inflation and the rising cost of running a home. With increases in electricity, oil and gas prices, households are likely to face additional costs on their annual energy bills. Making some of these changes in your home may help you avoid hefty winter bills later this year.

Improving the building energy rating (BER) of your house will make your home warmer, reduce your costs and carbon emissions. As a bonus, it will also increase the overall value of your home. We are here to help with our tips on how to improve your house’s energy rating.

Improving your BER rating

BER ratings are based on the amount of energy a home needs for ventilation, light, space, heating, and many other factors. Your home’s insulation, windows, doors and age are also taken into consideration when calculating its rating. When undergoing any new home renovations, it is recommended you aim for a B2 energy rating.

1. Upgrade your home’s insulation

The first and most effective step in improving the heat you already have in your home is upgrading your insulation. Homes lose on average up to 30 % heat from walls alone and another 30% through attics with poor insulation.

New insulation will not only decrease your heat loss but also your energy consumption, keeping your home warmer for longer. Any other energy improvements in your home will also benefit from an upgrade in insulation.

2. Replace your boiler

While replacing your boiler might seem like an expensive step, it is one home update that can make a difference in your newly insulated home. Replacing an old gas or oil boiler with an energy-efficient boiler or heat pump will directly impact your utility bills, make your home warmer, and reduce your homes carbon emissions.

3. Upgrade any single glazed windows

Single glazed windows are big culprits for allowing heat to escape from your home, you can lose up to 10% through windows and doors alone, so any single glazed windows or doors that are unsealed should be a priority. Your windows and doors are also taken into consideration for BER ratings. Your home’s windows doors and insulation all work together to keep the heat in and bills down, so updating one without the other would be counterproductive.

4. Review your ventilation

Draughts throughout the house can be a cause of energy loss, upgrading older vents can help increase airflow through your home. If you have any fireplaces in your home that are not in use, make sure the flue is closed to keep warm air from escaping out of the fireplace. But remember to open it before using the fireplace again. Similarly, a chimney balloon can help reduce draughts and heat from escaping.

5. Reduce your hot water thermostat

Overheating your water can be a big waste of energy and money, the optimal setting for your hot water thermostat should be 65 degrees celsius. Installing a smart thermostat can also help you be more efficient with your energy use and increase your house’s energy rating.

6. Make use of your heating control timers

Set up timers on your heating controls, don’t waste money on heating when you’re out of the house. Setting up timers so your home is warm when you are there is a much more efficient way of using your energy systems.

7. Invest in a lagging Jacket

Keep your hot water warm for longer with a lagging jacket for your heating system, it’s a simple and effective way to save you from boosting up the hot water that extra hour every day.

8. Have your boiler serviced regularly

Having your boiler regularly serviced is a great way to avoid your boiler breaking down in the depths of winter. An annual boiler service can also help ensure your boiler is running efficiently, a professional will know how to fix any leaks and make the relevant tweaks for you.

9. Upgrade your light bulbs to low energy

Low energy light bulbs can have a noticeable impact on our electricity bills, switching out any older non-efficient bulbs is one of the simplest ways you can improve your house’s energy rating.

10. Invest in renewable energy systems

Invest in renewable energy systems. Investing in your home by installing solar panels is undoubtedly one of the most proven ways to increase your home’s energy rating. It is an investment but one that can have a long-lasting impact on your energy bills and also increase the overall value of your home. SEAI have several grants on offer to help you install renewable energy in your home.
