If you’re planning to renovate your kitchen some time soon, you likely to be considering new kitchen units, stylish stone worktops and perhaps an AGA too – and why wouldn’t you? They help keep the house warm, look stunning and do so much more than just cook great tasting food. However, AGA cookers haven’t always received positive press in the past and have a reputation for being expensive to run. This isn’t necessarily the case with the newer cookers and you might find them surprisingly cost effective.

In this article, we take a look at the positives and benefits of owning an AGA, how much they cost to run and how much money they could save you.

Benefits of having an AGA

AGAs are made from cast iron and are therefore extremely good at efficiently storing heat, making them lovely and warm at all times and always ready to cook. When you do come to use your AGA, the heat is transferred throughout its ovens and hotplates at a steady rate. You won’t find many conventional dials or switches on an AGA, as it looks after itself, maintaining consistent temperatures. You have nothing to worry about – it’s no wonder that so many owners claim that cooking on an AGA is much easier than on a regular oven.

You’ll find that not only does food cook quicker in an AGA, it tastes better too. This is because AGA cookers use radiant heat, which helps lock in the moisture, flavour and texture of whatever you’re making. You can bake, fry, grill, toast, roast, stew, steam, simmer and stir-fry on your AGA, meaning you don’t have to bother owning a lot of other kitchen appliances, as it pretty much does everything. So your kitchen worktops can stay uncluttered, leaving granite or quartz countertops to look their very best . Many people even use AGAs to help air out their clothes.

Disadvantages of having an AGA

For most, the biggest disadvantage of an AGA is the potential added cost – older models in particular can be expensive to run. However, this is not the case with newer models which can be run from under £12 per week.

This is partly down to the fact older AGAs were designed to be left on all the time. In the winter, this means you have a warm, toasty home, but in the summer that heat might be unbearable unless you have several fans to hand or air conditioning, which can also be costly to run. Many AGA owners have a second cooker for the summer months instead, but this is another added cost, plus you need to have room to be able to store both appliances in your kitchen.

Why are AGAs seen as expensive?

In the past, AGA cookers only really worked properly if they were left turned on all the time. This is no longer the case. While each cast-iron cooker can still put useful heat into the room, meaning you get that indefinable AGA warmth, with today’s AGA cookers you have the option of turning ovens and hotplates off when you don’t need that warmth, for example on the hottest of summer days, overnight or when you’re away from home. If you do switch a newer AGA off, it’ll only take an hour for it to be fully heated up again.

A good investment

The initial cost of an AGA depends on what sort of model you go for, but a new, two-oven model costs around £5,925 fitted. That may seem like quite a lot to spend, but if you’re happy in your current home and plan to stay there for a while, it’s a good investment – one which will likely add value to your property. To match the quality of an AGA cooker, it’s also worth investing in highest-quality worktops, which look fantastic and needn’t break the bank. You can easily get a quote here for excellently fitted worktops in granite and quartz, as well as options in Arenastone, Caesarstone, Lundhs, Silestone Quartz, Samsung Radianz™ and Lapitec®.

Many AGAs last for more than 50 years, meaning you’ll probably never have to replace it in your lifetime. Moreover, because AGAs are multifunctional, you’ll save a lot of money on the cost of running and buying other kitchen appliances. Not to mention that there’ll be no need to turn on the radiators located near your kitchen ever again, as your AGA will keep the surrounding rooms nice and warm.

You can now choose an AGA in a glorious choice of colours, including bespoke options which allow you to pick exactly what you want, so you can create everything from a traditional farmhouse look to something much more contemporary and sleekly urban. Your AGA will always look best set next to a robust worktop in beautiful natural granite or attractively speckled quartz. Both are available in colours to match and enhance the look of your chosen AGA.

The average cost of running an AGA

As we’ve already mentioned, the cost of running an AGA largely depends on which model you buy. You now have the choice of AGA Everyday where ovens and hotplates can be independently controlled and turned on and off as you need them or left to run on a lower setting or AGA 24/7 which are on all the time. As an example, some AGAs left on an economy setting will cost just £7.55 per week to run. Whether you’re after two, three or four ovens, the 13-amp electric models cost the most to run. A two-oven 13-amp model will set you back £32.87 a week, a three-oven costs £37.35 a week and a four-oven is a whopping £40.34 a week!

In fact, unless you choose to opt for the smaller City 60, TC3 or Dual Electric models, the cheapest option is the 30-amp electric models. For a two-oven you can look to spend just £15.16 per week and a four-oven will consume around £18.48 of electricity a week. However, if you’re after a three-oven model, your cheapest option is actually natural gas at £17.33 a week.

Average savings you’ll make

AGAs essentially make toasters, bread makers and electric kettles redundant, as they can do the job of all these things and more. With this in mind, you could look to save between £7.94 and £11.33 per week, simply by not using such appliances.

You’ll also save on heating costs, as during the winter your always-on AGA will mean there’s little point in turning on the heating in the rooms nearby. By not turning on two gas radiators, you could cut down your heating costs by between £4.92 and £9.85 a week. If you have underfloor heating instead of radiators, expect to save a lot more.

However, it is worth bearing in mind that the estimated costs and savings are provided by AGA itself, so you might want to take the figures with a pinch of salt.

Although the upfront cost is a bit daunting, there are many good reasons to buy an AGA. They’re attractive, warm, improve the quality of your food and rarely cost more to run than the average cooker. Beware though, many AGA owners will tell you that once you’ve got one, you’ll never want to cook on anything else ever AGAin.
