Many people don’t think about this but it actually costs more to light a home than to heat a home say the experts Roof Maker. This is because it is rare to have the heating on through the summer months, but lights are used on a daily basis and more so through the winter months when the dark nights are drawing in, so the overall cost is higher.
Building an extension therefore doesn’t necessary cost more in terms of heating, but think about the lighting. One way of reducing the bills is to ensure homes are filled with as much natural light as possible. This can be achieved by using a neutral colour palette on walls and ensuring the rooms are flooded with natural light by including rooflights and bi-fold or sliding doors.
