Work out how much it costs for the electricity to run various household appliances. You can either select one of the common appliances from the dropdown below to see typical costs, or if you are trying to find the cost of running an appliance that isn't listed here, you can enter your own values in the boxes provided.

Using the electricity cost calculator
The cost of using any electrical device can be quickly estimated:
Wattage x time used x price of electricity.
In this calculator, we estimate costs over the course of a year so the numbers are easy to make sense of. In this case, the calculation becomes the average power needed while in use (wattage), multiplied by the amount of time it is used (minutes/day), times the price of electricity (pence/kWh).
This is a quick and useful way to estimate the cost of using an appliance, but it does have its limitations. It works well for appliances with stable power demands (like lights, TVs, and kettles) but is not great for things that have highly variable wattage (like fridges and washing machines).
To help improve your understanding of these issues let's look at some more data.
Electricity costs per hour
A really simple way to understand the relative costs of using different appliances is to compare their costs per hour. In the graph below we show how many pence per hour it costs to run different lights, computers and lights.
Although the unit of pence/hour is a bit hard to relate to, the relative cost is what is important. This shows you why switching to LEDs is so much cheaper and how energy use in TVs varies by screen size.
Electricity costs per cycle
For appliances that have quite variable loads, just looking at their total wattage can be a bit misleading. That’s because total wattage might not reflect how efficient an appliance is across a full cycle. To think more clearly about these appliances it’s useful to know how much they costs per cycle, or use.
As we can see in the graph above clothes dryers are one of the most expensive products to run, with inefficient ones costing more than 50p per use. In homes that do a lot of clothes drying, investing in a more efficient dryer is a sensible idea.
When washing clothes the major energy cost is normally heating water. Save energy by washing your clothes at a colder temperature.
For other appliances such as ovens, hobs and kettles it’s easiest to simply read the product label to ensure you get as efficient a model as possible.
Electricity costs per year
If you are looking to cut down your electricity use then it's very important to have some context. This will stop you wasting time on trivial processes, like unplugging your phone charger, and instead dial-in on important electricity demands. Although your own home's electricity use will be unique, understanding how an average home spends on electricity can be really useful.
The following graph shows the average electricity costs per home in the UK.
As you can see in the graph, although electricity is quite widely distributed in the home, there are five main areas where people typically spend a considerable amount. These are cold appliances, lighting, consumer electronics, cooking and wet appliances. Although low-efficiency products are typically cheaper when purchasing, over the course of their lifetime the electricity they use can really add up - especially if there are a lot of people in the house.
The potential savings of cheaper energy
In the calculator above, we provide you with a comparison between electricity costs using your selected tariff and those of the cheapest on the market. People on the most common standard variable tariff pay around 15 pence/kWh for their electricity, whereas on the cheaper tariffs on the market, this can fall to as little as 11 pence/kWh.
The graph below shows the potential savings of switching to a cheaper tariff would look across the energy use in a typical household, adding up to savings of as much as £150 per year.
The unit price for electricity used in this graph is 14 p/kWh for the standard tariff and 11 p/kWh for the cheaper tariff. Although a good representation of the market in general, you won’t really understand how much you might benefit from switching without getting a quote.
Since being with OVO, I have saved money on my bills. I love the fact that statements are easy to understand, they are updated regularly, and I take my own meter readings. I feel in charge of the amount of energy I use and I know exactly where I stand with my monthly payments. Another plus is that they can be contacted very easily and I do not have to wait for ages to speak to someone. Well done OVO.
A breath of fresh air
I switched to OVO in May 2014 on a two year fixed deal and immediately loved their friendly approach, easy to use website and clear bills. The 3% interest on credit balances is a bonus! My fixed contract is about to expire and I've already signed up for another year. I also recommended OVO to my daughter.
If only all Utilities were handled this well.
I found OVO very easy to deal with. Prices were competitive for my fixed price dual tariff. Switch was handled well and the only time I needed to contact them by phone the lady I dealt with handled my query with grace and speed. So much better than my last supplier who had totally lost the plot.
Excellent credentials and customer service!
OVO have always been excellent when I've contacted them, both friendly and knowledgeable! They're consistently cheaper for me than the competition and their green credentials really help as well.
Number one for energy
I moved to OVO 12 months ago after having a nightmare experience with Scottish Power and there is just no comparison between the 2 of them, your bill is so easy to understand and shows you everything you need to know. So easy to get through to by phone and you talk to very friendly and helpful people who you can tell are very happy in their job. They may not be quite the cheapest on the market but by far the best if you want customer service and reliability. No more big six boys for me.
I have no hesitation in recommending OVO not just for the clear and easy monthly reading/billing system but for the overall quality of service over the years - for example a recent technical query about PME (raised by our electrician) produced a quick and helpful response to my e-mail complete with our power distribution company contact telephone numbers and an offer to assist further if needed. They are one of the most efficient and responsive organisations that I have ever dealt with. Top marks.
