Running costs of electric Aga range cookers
What your electric Aga range cooker will cost to run, whether it's new from AGA Rangemaster or a Reimagined model from Blake & Bull, is not fixed. The answer can be complicated (have a look at AGA Rangemaster's own page on this!) but the principle is simple.
The trade off is convenience vs cost, the flexibility of electric gives you control
Leave the whole cooker on 24/7 and it will cost more but its certainly very handy! Turn the cooker on only when you need it though, while less convenient, and you can save a lot of money!
The most important point though is that with electric cookers you have that control. If fuel prices rise you can change how you use the cooker to save money.
For background warmth you need only the ovens; you may as well leave the hotplates off till you need them. This is an enormous saving even with ovens left on permanently.
But remember the ovens are flexible too! In the summer, when you don't need any background heat in the kitchen, you could turn on when you need them with a little forward planning.
In the autumn you may wish to run them on low and turn up when you need them. In the winter by all means leave those ovens on so they are always ready for action, warming the kitchen and drying all those soggy clothes!
