Blenders could be costing some UK households around £4.41 a year from the start of next month, according to calculations by The Express. From April 1, people in England, Wales, and Scotland on a standard variable tariff, and who pay for their electricity via Direct Debit, will pay 24.67p per kilowatt hour (kWh) on average.

That's represents a 7% reduction on the current price cap of 27.69p per kWh, with Ofgem saying the main cause of the decrease is Government budget interventions. As a result, you may soon find your electricity bills are lower, but it's worth being aware of how multiple appliances can add to your electricity costs over time, particularly ones you use often.

That includes blenders, a popular way to prepare smoothies, and soups. A study by Uswitch published January looking at appliance usage and costs estimated that electric blender/juicers see 31.9 minutes of use per week on average.

According to electronics firm Royal Electronics Group, a "blender with power between 500W and 800W should be sufficient for most households", and will be able to deal with things like grains and cereals.

To get a rough idea of costs, let's say a rough average usage per weeks is 32 minutes, with a 650W appliance.

Smart Money Tools' Electricity Cost Calculator allows to enter this information and estimate costs over 12 months under a certain price cap.

According to the tool, at that level of power consumption and usage, a typical blender would add around £4.95 to your elecricity bill over 12 months under the current cap (27.69p per kWh).

That level of usage works out to approximately £0.03p per 10 mins, £0.01 per day, and £0.41 per month.

Under the April 1 price cap (24.67p), the cost of the same usage would drop to around £4.41 over 12 months, or:

• £0.03 per 10 mins
• £0.01 per day
• £0.37 per month
• £4.41 per year

However, usage - and therefore costs - will obviously vary greatly, and there's also a wide range in tmers of power power output and efficiency between models.

Also, while these estimates help us give a sense of the broad costs the cap represents over a longer period, the maximum limit on unit rates and standard charges is reviewed by the regulator every three months and doesn't stay in place for a full year.

Meanwhile, the standing charge will rise slightly from its current 54.75p level to 57.21p per day. The April 1 price cap will apply until June 30, with the next cap level announced on May 27.
