Energy Bills: Uswitch Looks at Rising Running Costs for Aga Kitchens, Hot Tubs and Pools


While skyrocketing gas and electricity bill prices are hitting Brits across the country, they are also having a big impact on the property running costs of the super-rich thanks to their high-energy homes.

And the economics of running an Aga cooker, known as ‘aganomics’, are now among the top issues of the upper classes who currently have a bill of £1,208 a year to run an electric model at the price cap rate. of Ofgem.

Uswitch analysts said a 42 percent power cap increase in October, which is the current market estimate, would make the annual operating bill for such a furnace, which is designed to be always on, will reach £1,717 per year.


The concept of ‘aganomics’ – described as an ‘economic sub-discipline’ by Which? – sees people consider the efficiency of different types of Agas and fuels, including how they too negate the need for heating in a kitchen.

Running cost figures are based on a £9,720 Aga eR3 series electric cooker using 82kWh of energy per week when leaving its two ovens at full temperature continuously, giving a yearly total of 4,264kWh .

Others at the top of the social ladder in the UK have to consider the high energy bills generated by hot tubs, which were a popular purchase at the start of the pandemic by Britons in lockdown.

Experts at Uswitch looked at the seven-person Lay-Z-Spa Helsinki AirJet hot tub, which costs £700. Using this for six hours a week would require an annual total of 624kWh, equivalent to £177 now, or £251 a from October.

Another luxury equipment considered by Uswitch is underfloor heating, which has a power of 150W per square meter. Assuming a 10 square meter room, running for four hours a day, this would be an annual energy use of 2,190 kWh. Under the current power cap this would cost £621, but would rise to £882 from October.

The figures are based on a unit tariff for electricity of 28p now, and then an estimated 42 per cent rise in cost for October, taking average total household bills from £1,971 to £2,800, when there could be a tariff. unit of 40 pence.

The price comparison analysts also looked at the cost of heating an outdoor swimming pool and used the example of a power of 50 W per square meter for an option of 11 m by 4 m with a good thermal cover.

Assuming the heater runs for eight hours a day and the pool stays warm for five months a year, this would give an annual energy use of 2,640 kWh, and a cost of £748 a year now or £1,063 from October. .

Another item considered was a Peloton exercise bike, for which experts say has an electricity cost of 27 pence for an hour-long workout below the current price cap, but this would rise to 39 pence in October.

The Uswitch team also looked at an air conditioning unit, which would cost £5.39 per week for one hour per day. A weekly cost of just over nine hours a day is £49 below the current cap, which is set to hit £69 in October.

Finally, they also reviewed a home cinema system consisting of a £799 LG CineBeam HF65LSR projector, four Dolby Atmos speakers costing £258 in total, and a Dolby Atmos and DTS:X AV amplifier costing £2,199.

Experts then made a calculation for a two-hour movie, saying it would currently cost 60 pence, but would rise to 85 pence in October. This was based on the system using 200W speakers, 100W projector and 750W amplifier.

An energy expert from Uswitch told MailOnline: “We are all familiar with the rising price of heating our homes, but those who live in more luxurious settings may find that their lifestyle drives additional costs.”

‘Keeping an outdoor pool warm is a constant battle against the elements, and will cost around £5 a day for electricity during the summer months. Heat loss can be reduced by using a solar blanket to cover the pool, and heat pumps are cheaper to run than an electric heating system.

Ofgem's energy price cap has already risen to an average of £1,971 a year, but could rise further to £2,800 in October.

Ofgem’s energy price cap has already risen to an average of £1,971 a year, but could rise further to £2,800 in October.

“Air conditioning costs can add up quickly, especially during the hottest days when users turn on their system for nine hours a day on average, adding over £48 a week to current energy prices.”

Power bills have risen 54 per cent, to an average £693, this year and will rise another £800, to an average £2,800 per year, when energy regulator Ofgem raises the price cap again in October.

And the Uswitch expert added: ‘With Ofgem predicting that the price cap will rise to £2,800 in October, all these high-end devices will only get more expensive to use.

‘When purchasing any new device or appliance, remember to consider not only the total cost, but also how much it will cost to run. Sometimes the most energy efficient devices are more expensive, but they will save you money in the long run.’

Chancellor Rishi Sunak unveiled a £21bn giveaway last month to help families with the cost of living, saying each household will receive £400 to help with energy bills, with those most in need receiving up to £400. 1,500.
