Improving your BER rating can greatly reduce your energy bills and carbon footprint. A BER assessor will identify areas where your property can be more energy efficient. Some common areas to improve include insulation, heating controls, and hot water systems. Upgrading to energy efficient appliances and installing renewable energy sources such as solar panels can also improve your BER rating. Having solar panels fitted to your home can save you money overall. The SEAI provide grants for people who want to use renewable energy, such as the solar electricity grant and the solar water heating grant.
