Aga Running Costs Explained
What Does It Really Cost to Run an Aga Cooker?
Aga cookers are iconic for their warmth, reliability, and style. But with changing fuel prices and more flexible modern living, most UK homeowners now ask: What are the true running costs of an Aga? The answer depends on fuel type, model, usage pattern, and crucially, whether your Aga uses classic oil/gas, old-style electric, or a modern electric conversion kit.
Below is the latest, most trustworthy breakdown of Aga running costs across all major types, gas, oil, and electric, including up-to-date price examples based on current UK tariffs. We’ve also included detailed charts, comparisons, and real-world examples, plus advice on cutting your bills and upgrading your range cooker for maximum efficiency.
Traditional Aga Running Costs
The table below shows the weekly fuel cost of a traditional, always-on Aga for each fuel and oven size. Each cost is the Aga maker's published weekly consumption for that model multiplied by the unit price in the final column, so every row can be checked against your own tariff.
| Fuel | 2-oven | 3-oven | 4-oven | Unit Price |
|---|---|---|---|---|
| Gas | £33.87 (425 kWh) | £33.87 (425 kWh) | £42.00 (527 kWh) | 7.97p/kWh |
| Oil | £47.36 (40 litres) | n/a | £60.39 (51 litres) | 118.4p/litre |
| 13 Amp electric | £57.90 (220 kWh) | £63.17 (240 kWh) | £71.06 (270 kWh) | 26.32p/kWh |
On these figures gas is the cheapest of the traditional fuels to run. The 13 amp electric Aga costs the most by a wide margin, which is why we only suggest one where there is no gas supply and no room for an oil tank.
Oil has changed the most. A 2-oven oil Aga cost about £25 a week in January 2026 and now costs about £47, because heating oil has risen from about 61p to over 118p a litre including VAT this year.
Weekly consumption is the Aga maker's published figure for each model. Unit prices: gas and standard electricity are Ofgem's average Direct Debit rates for 1 October to 31 December 2026; heating oil is Fueltool's October 2026 average for a 1,000 to 1,499 litre delivery, 112.77p a litre plus VAT at 5%. Standing charges are excluded, and your own cost will vary with your tariff, your kitchen and how well the cooker is insulated.
Saving tip: you do not need a new cooker to cut these bills. We convert gas and oil Agas to electric during a full Aga refurbishment, and we also sell reconditioned Agas ready to run.
Traditional Aga costs over a year
- £2,463 2-oven oil Aga
- £3,140 4-oven oil Aga
- £1,761 2-oven or 3-oven gas Aga
- £3,011 2-oven 13 amp Aga
The weekly costs in the table above, times 52, at the October 2026 unit prices.
Aga Dual Control and Total Control Running Costs
The controllable electric Aga models, Dual Control and Total Control, let you idle the cooker between meals instead of running it flat out all week. These are the weekly costs for each setting, excluding hotplate use.
In eco or slumber mode
| Model | 3-oven | 5-oven (hotcupboard on) |
|---|---|---|
| Dual Control (R7) | £27.64 (105 kWh) | £41.79 (158.76 kWh) |
| Total Control (Er7) | £14.21 (54 kWh) | £28.36 (107.76 kWh) |
On the full setting
| Model | 3-oven | 5-oven (hotcupboard on) |
|---|---|---|
| Dual Control (R7) | £37.64 (143 kWh) | £51.79 (196.76 kWh) |
| Total Control (Er7) | £29.22 (111 kWh) | £43.36 (164.76 kWh) |
Hotplates, cost per hour at full heat
| Hotplate | Energy Per Hour | Cost Per Hour |
|---|---|---|
| Simmering plate | 0.24 kWh | £0.06 |
| Boiling plate | 0.54 kWh | £0.14 |
| Both plates together | 0.78 kWh | £0.21 |
Both plates flat out for an hour a day add about £1.44 a week on either model.
ElectricKit Advanced Running Costs
How much does an electric Aga cost to run?
One of the benefits of an ElectricKit Advanced conversion is the flexibility to choose how you use it. Whether you prefer to keep your Aga warm and ready to cook throughout the day or switch it on only when needed, your running costs will depend on your cooking habits, temperature settings and the number of ovens and hobs in use.
To help you understand the potential costs, we have calculated estimated electricity consumption for six typical usage scenarios, covering both 2-oven and 4-oven models.
Estimated running costs
The estimates below use an electricity unit rate of 26.32p per kWh, based on Ofgem’s Great Britain average for customers paying by Direct Debit on a standard variable tariff between 1 October and 31 December 2026.
| Typical usage | 2-oven Aga, per day | 4-oven Aga, per day |
|---|---|---|
| 1. Always ready to cook | £8.26 | £9.92 |
| 2. Keeping the main oven hot | £5.23 | £6.89 |
| 3. Reduced oven temperature between meals | £4.13 | £5.39 |
| 4. Cooking when required | £0.73 | £1.07 |
| 5. Daytime cooking, switched off overnight | £1.56 | £2.21 |
| 6. Simmering hotplate always on, evening oven on timer | £2.95 | £3.28 |
- Always ready to cook: Both hobs operating continuously, one at simmering temperature and one at boiling temperature, with the top oven at roasting temperature and the bottom oven at simmering temperature.
- Keeping the main oven hot: One hob at simmering temperature and the top oven maintained at roasting temperature, 24 hours a day.
- Reduced oven temperature between meals: One hob at simmering temperature, with the oven maintained at 100°C between cooking sessions and available for roasting.
- Cooking when required: One daily timed cooking session, with the hobs switched off except for one hour of boiling-temperature hob use.
- Daytime cooking, switched off overnight: The main oven is maintained at approximately 200°C from 8am until 7pm (11 hours per day), then switched off overnight. One hob is used at boiling temperature (setting 6) and one at simmering temperature (setting 4), for two hours per day each. Both hobs are switched off between cooking periods.
- Simmering hotplate always on, evening oven on timer: Enjoy the convenience of having a hotplate ready for everyday cooking, while keeping oven running costs under control. The simmering hotplate is left on continuously, 24 hours a day, providing a convenient surface for everyday tasks such as making toast, cooking eggs or heating a saucepan. The top oven is programmed to switch on automatically at 3pm and switch off at 7pm. This means your oven is ready for evening cooking without needing to remain hot throughout the day and night.
What could this mean each month?
The following figures show the average monthly running cost, assuming the same usage every day throughout the year.
| Typical usage | 2-oven Aga, per month | 4-oven Aga, per month |
|---|---|---|
| Always ready to cook | £251 | £302 |
| Main oven kept hot | £159 | £210 |
| Reduced oven temperature between meals | £126 | £164 |
| Cooking when required | £22 | £33 |
| Daytime cooking, switched off overnight | £47 | £67 |
| Simmering hotplate always on, evening oven on timer | £90 | £100 |
How are these figures calculated?
The estimates are based on the manufacturer’s published ElectricKit consumption figures:
- Individual hobs use approximately 0.37 kWh per hour at setting 4, and 0.46 kWh per hour at setting 6.
- Continuous oven operation at roasting temperature is taken as 11 kWh per day for a 2-oven model (John Wray’s figure for the ElectricKit Advanced) and 17.28 kWh per day for a 4-oven model.
- Continuous operation with the ovens turned down between meals is quoted at 6.82 kWh per day for a 2-oven model and 11.58 kWh per day for a 4-oven model.
- Timed cooking once per day is quoted at 2.32 kWh per day for a 2-oven model and 3.6 kWh per day for a 4-oven model.
- Using the bottom oven control at simmering temperature adds approximately 0.02 kWh per hour once the cooker is up to temperature.
The manufacturer’s figures include warm-up and typical cooking usage where applicable. Where a scenario combines different hob and oven settings, we have calculated the estimated total using the relevant published figures.
For scenario 5, the estimate assumes that an oven operating at 200°C consumes approximately 85% of the electricity required when maintained at full roasting temperature. This is an estimated consumption rate, as the manufacturer does not provide a specific published figure for continuous operation at 200°C. Hob consumption is calculated using the manufacturer’s published figures of 0.46 kWh per hour at setting 6 and 0.37 kWh per hour at setting 4. The calculation does not include a separately measured allowance for reheating the oven from cold each morning.
For scenario 6, the simmering hotplate consumption is based on the manufacturer’s published figure of approximately 0.37 kWh per hour, equivalent to 8.88 kWh over 24 hours. Oven consumption is based on the manufacturer’s published timed cooking figures of 2.32 kWh per day for a 2-oven model and 3.6 kWh per day for a 4-oven model.
Important information
These figures are estimates intended to help with budgeting and comparison. Actual electricity consumption and running costs will vary according to your electricity tariff, temperature settings, frequency of use, cooking habits and installation. The hob figures are for the standard hotplates; an optional induction hob changes them.
The timed-cooking figures are based on the manufacturer’s stated average cooking session and may not represent every cooking routine. The 4-oven model’s consumption may also be reduced when the warming oven is not required.
Electricity prices vary by supplier, tariff and region. We have used the Ofgem Great Britain average unit rate for the period stated above, excluding any household electricity standing charge. Monthly estimates represent an average across 12 months; actual bills will vary with usage and electricity prices.
At John Wray Range Cookers, we believe in helping you make an informed choice. If you are considering an ElectricKit Advanced conversion, we can talk you through the available options and help you find a setup that suits your cooking needs and lifestyle.
We fit four systems: ElectricKit Classic, ElectricKit Advanced, eControl Series X and eControl Series X-Squared. There is more detail on our Electric Aga Conversions page.

Extra Ways to Save with Electric Conversions
Beyond the weekly cost savings, modern conversions bring several hidden advantages:
- Less Heat Loss in Summer, unlike traditional Agas that run constantly, conversions let you switch off heat sources when not in use, keeping your kitchen cooler and reducing the need for extra ventilation.
- Lower Maintenance Costs, no flue, no oil tank, and fewer moving parts mean fewer repairs and lower annual servicing bills.
- Greener Energy Choices, pairing your electric Aga with an off-peak tariff or renewable energy source can cut bills even further and reduce your carbon footprint.
- Future-Proofing, with energy prices fluctuating, having the flexibility to adapt your cooking schedule and energy source gives you long-term security.
- Improved Cooking Control, precise temperature management allows you to run only the ovens or hotplates you need, without sacrificing performance.
Real-World Example: One of our customers in rural Northumberland converted their ageing 2-oven oil Aga to an ElectricKit Advanced Conversion during an Aga refurbishment. Their annual running costs dropped from around £1,900 to approximately £520. They also eliminated the need for oil deliveries, reduced kitchen overheating in summer, and now have the flexibility to switch ovens and hotplates on only when needed, perfect for their busy but energy-conscious household.
Conclusion: Which Aga Is the Cheapest to Run?
Yearly running cost by Aga type
If running costs are your main concern, a modern electric conversion used flexibly is the clear winner.
- ElectricKit Advanced: from about £5 a week for one timed cooking session a day plus an hour of hob use, to about £58 a week with both hobs and the ovens on around the clock, for a 2-oven model, worked from the daily figures above multiplied by seven.
- ElectricKit Classic: simpler controls than the Advanced. Ask us for a running cost estimate for the way you cook.
By comparison, traditional gas, oil, or always-on electric Agas cost £1,700 to £3,700 per year to run.
Bottom line: Upgrading your existing Aga to a modern electric system and using it flexibly pays for itself quickly, lowers your bills, and lets you keep all the classic benefits of Aga cooking without the financial strain.
Aga Running Costs FAQs
How much does it cost to run a gas Aga per week?
A 2-oven or 3-oven natural gas Aga uses about 425 kWh a week, which is £33.87 at 7.97p/kWh. A 4-oven model uses about 527 kWh, or £42.00 a week. On LPG, common off-grid, expect close to double.
Are oil Agas expensive to run?
A 2-oven oil Aga burns about 40 litres a week, which is £47.36 at 118.4p a litre including VAT, and a 4-oven about 51 litres, or £60.39. Heating oil has moved from about 61p to over 118p a litre during 2026, so the same cooker costs nearly double what it did in January.
What is the cheapest type of Aga to run?
A modern electric conversion used flexibly. With an ElectricKit Advanced conversion, one timed cooking session a day plus an hour of hob use costs about £0.73 a day for a 2-oven Aga, around £5 a week, against £57.90 a week for the same cooker as a 13 amp electric Aga.
How do electric Aga conversions save money?
Each oven and hotplate has its own control, so you only heat what you need, when you need it. Turned down or switched off between meals, that cuts energy use by half or more against a 13 amp Aga. Left at roasting temperature with both hobs on around the clock, it uses about the same (see the ElectricKit table above).
How much electricity does an Aga conversion use?
It depends on how you use it. On the figures we use, a 2-oven conversion takes about 2.32 kWh a day for one timed cooking session, 6.82 kWh a day with the ovens turned down to 100°C between meals and 11 kWh a day left at roasting temperature around the clock, before any hob use. A 4-oven model uses about 3.6, 11.58 and 17.28 kWh a day on the same settings. Usage, not the kit, decides the bill.
How quickly will an electric conversion pay for itself?
Most customers recover the cost of a conversion in 2 to 4 years through reduced fuel bills. In high-use households switching from old electric or oil Agas, the payback can be even faster.
