What is a BER certificate

A Building Energy Rating (BER) certificate indicates your building’s energy performance. It is similar to the energy label for household appliances.

The certificate rates your building on a scale of A-G. A-rated homes are the most energy efficient and will tend to have the lowest energy bills. G-rated are the least energy efficient.

How a BER is calculated

Your BER is calculated through energy use for space and hot water heating, ventilation, and lighting.

The number of people likely to occupy a building is also taken in consideration. This is based on the average number of occupants in buildings of a similar size.

Tips to improve your BER

There are some smaller changes you can make which will also result in energy savings and an improved BER.

Replace or seal old windows

Single-glazed windows tend to be lose a lot of heat. In many cases, draught-stripping will improve this but secondary glazing or complete window replacement can return highest overall savings.

Choose low energy lighting

Replace old inefficient bulbs with low-energy light bulbs for a noticeable improvement in electricity bills.

Check your ventilation

Try to reduce draughts and install a chimney balloon in your fireplace when it’s not in use to keep heat in. Older vents may need replacing to encourage better airflow.

Get a lagging jacket

A thick lagging jacket for your hot water cylinder will keep your water warmer for longer, improving your BER and saving you money.
