Aga Cooker Running Costs

How Much Does it Cost to Run an Aga Cooker?

We offer a wide range of Refurbished Aga Cookers, from the traditional 'always on' oil models, to the flexible electric conversion systems. Each come with their own features, characteristics and energy consumption.


With the energy price hikes, it's important to consider which model suits your lifestyle and budget best.


Let's take a look at the running costs of Aga Cookers, using a standard UK energy tariff.

How Much Does an Aga Cost to Run?

Traditional Oil, Gas and 13amp Aga Cookers are designed to be always on and ready to use.


Back when energy prices were lower (and more stable!), these were very popular for throwing lots of ambient heat into the room and the convenience of cooking whenever needed with an 'always hot' oven/hotplate.


As times progress, more people prefer flexibility and the option to control their running costs by turning parts of the Aga Cooker on/off or up/down whenever needed. This is why our ElectricKit Conversions are so popular, alongside the induction hob upgrades.


It's hard to measure the different models like-for-like, as they all have different purposes. The traditional models will always be on, whereas the ElectricKit Conversions are designed to be used flexibly. All of our Refurbished Aga Cookers have British-Made, cast iron ovens which work best when saturated with heat.

Weekly Aga Running Costs:

Oil, Gas and 13amp are measured running 24/7, as recommended.

ElectricKit and eControl conversions are designed to be used flexibly for cheaper running costs vs traditional models.

For efficient running costs and traditional ambient heat, take a look at our other Range Cooker options:


Everhot Cookers or Esse Cookers.


With the ElectricKit and eControl, you would tend to use these flexibly when looking to reduce your running costs, but you also have the option of leaving the hotplates and/or ovens on 24/7 for more ambient heat into the room in the cooler months.

Our black steel plinths are available to add onto your cooker order if required. They add additional height to the overall Aga dimensions and are available in multiple heights to suit your kitchen design. Traditionally, these British-made Aga Cookers were 851mm from the base to the top of the black enamelled surface. When do you need a plinth? If your worktop or ideal working height is taller than 851mm and you want your Aga Cooker to match them, you'll need a plinth underneath. Brand new Aga Cookers (as well as our ESSE and Everhot cookers) have a fixed height plinth built into the cooker body. If you need these raised higher, you'll need to lay marine-grade plywood or concrete at the required height before installation. What sizes of plinths are available? Our plinths are available in 50mm to 80mm sizes. They also allow for levelling of the base before the assembly of the cooker begins. How do I choose my plinth size? When choosing your required height, you should consider your finished floor height vs your worktop height. It's standard for Aga Cookers to finish slightly proud of the worktop, since the top plate is curved rather than a right-angle ( photo shown below ). If you were to finish level with the worktop, you will have a bigger 'valley' in-between, where crumbs and debris love to collect! Usually, the plinth is seated onto the subfloor, with finished flooring/tiles ran up to and around the plinth once the cooker is built. Alternatively, you can either seat the plinth directly onto the finished floor/tiles, as long as they can bare the weight of the cooker, or we can raise the plinth using the adjustment legs, to allow the finished floor to tuck underneath slightly ( photo shown below). If choosing this option, you should bare in mind the supporting feet in each corner of the plinth start at around 20mm from the front of the plinth. This means your flooring could run underneath for a depth of around 20mm if preferred. After the cooker is built, there are NO adjustments in height, without a strip down and rebuild. What do Aga Cooker plinths look like?

The internal cavities of Aga Cookers have historically been filled with loose-fill insulation. Inside the cooker body, there are lots of pockets and gaps around the cast iron conductions and burner casings etc. The insulation was poured inside after the build was complete, to rid the cooker of air pockets and insulate the cooker body. Diatomaceous Powder Insulation Early models of Aga cooker, like the Standard models made from the 1950's through to the Deluxe 1974 models (and some post-1974 models), would have originally contained Kieselguhr insulation power (or 'Diatomaceous Earth'). You can identify your model here. This is a fine, talc-like insulation, made from crushed up fossils called diatoms. It's satisfying to touch, but VERY messy to work with and instantly becomes thick clay once exposed to water or moisture. The good news is that amorphous diatomaceous earth is non-toxic. As with anything in powder or dust form - minimising exposure is key. You don't want to be breathing in lung-fulls of any dust or powder. If you're working with it, the proper PPE should be used; not just cloth or paper dust masks. Whilst the loose fill insulation may be ok, these models are still the most at risk for any asbestos exposure. AGA used asbestos rope seals inside their cookers for many years. These seals and gaskets are found inside the body of the older models explained above, and also around the lids and doors. Over the lifetime of these cookers, many of these gaskets and rope seals have been replaced for modern (safe) equivalents. AGA have previously reassured engineers and customers that undisturbed, these seals pose little risk and were of 'dust suppressed' or 'tightly woven' formats. Many of them have been exposed to moisture or grease over time which hardens them, meaning they're less friable in nature. They recommend that really old models of cooker are removed in one piece if possible and disposed of professionally.
