The running costs of electric Aga range cookers from Blake & Bull can vary significantly depending on how you choose to use your cooker, especially because these cookers can easily be switched on and off unlike conventional Agas.
On average, you can expect weekly costs ranging from £15-20 per week, significantly less than £35 - £40 per week on an equivalent gas/oil Aga cooker.
The difference between running a smaller 2-oven or 3-oven electric Aga vs a larger 4-oven or 5-oven Aga can be around £6/week, although this depends a lot on how often you keep it on for.
