AGA Running Costs
Home AGA AGA Range Cookers AGA Running Costs
AGA running costs depend upon the model that you own, the fuel supply you use and how you use your cooker. Whilst an AGA may be more expensive to run when compared to a conventional range cooker or built in oven, an AGA will also take the place of other electrical items such as radiators, an electric kettle, slow cooker, toaster and a tumble drier. All these aspects should be factored in when trying to compare running costs and a cumulative approach should be considered when trying to understand the impact an AGA will have on your household.
The new generation of AGA Models now provide increased flexibility and greater control, providing the opportunity to lower running costs significantly thanks to fast heat up times and the ability to allow individual operation of ovens and hotplates. In addition, adjustable temperatures and the ability to turn off functions when not required enables you to control how much energy you use.
The Everyday Radiant Heat (ER Series) range of AGA cookers, which includes the AGA eR3 Series and the AGA eR7 Series, are the most fuel-efficient AGA cooker in today’s market. They are much more controllable than the older generation AGA cookers and are designed to be switched on and off as required.
The 24/7 Radiant Heat (R Series) collection are designed to always be on and ready to cook. Much like a traditional AGA but improvements in design and control options allow for a more efficient and cheaper way to achieve a more traditional AGA lifestyle.
Note: We have produced this page as a guide to give you a better understanding on the current estimated running costs of each model of AGA cooker, all information provided is sourced from AGA and individual circumstances i.e. current energy plan, usage of the appliance and other external factors should be taken into consideration when comparing with the information provided
