How do I reduce my home energy bills?
Have you any advice to help me reduce my home energy bills without spending too much money? John in Carlow.
This is a question that I am regularly asked, as homeowners in the current climate are looking to maximise the savings returns on energy improvement measures undertaken. In the table below I have outlined various energy savings measures a householder can undertake, starting from a very low cost base, while outlining the potential savings that can be achieved with each measure in a typical 150 m² home.
