How to reduce home energy cost

If your home’s energy, electricity, and gas costs are rising, you might be looking at various appliances around your home and wondering what each is costing you, and if you could find a cheaper, or greener solution.

With so many appliances dotted around the house, it’s not always obvious what appliances or machines are costing you the most. We’ve put together a list of the standard running costs of everyday household appliances so you’re more aware of exactly how much you’re spending – and to make sure you’re budgeting yourself accordingly.

What is the average cost of electricity and gas in the UK?

It’s worth knowing what the average cost of electricity and gas is in the UK, so you can work out how much you’re spending.

According to British Gas, in March 2022, the average price of electricity stood at around 28p per kWh, and gas at 7.3p per kWh with a 27p per day standing charge.

Of course, you should know that your utility bills can go up or down at any moment. Unfortunately, sometimes, certain factors are out of your control, e.g., energy price caps can be raised. You should always make sure to keep up with the latest news announcements so you’re not being caught out – if you can help it.

How much do household appliances cost?

Household appliances like washing machines, fridges and TVs often cost less to run that you think – although you can still make savings.

Washing machines

Washing machine energy ratings are now based on 100 cycles, with ‘A+++’ being the most efficient and ‘D’ being the least efficient. An A rated machine will use around 50kWh per 100 loads, so based on an average of five loads per week, will cost you around £35 per year. A ‘D’ rated appliance uses nearer to 70 kWh for the same wash, which works out at £49.

Tumble dryers

A tumble dryer is much more expensive. For example, a 9kg vented tumble dryer uses more than 5kWh for a full cycle which works out at £1.40. If you were to use your tumble dryer for each of those washing loads, five times a week, every week for the year, you’d be looking at using your dryer 250 times throughout the year – which works out at £350 annually.

Fridge Freezers

The same simple energy rating is used on fridge-freezers. A ‘C’ rated 70/30 fridge freezer will use approximately 165 kWh of electricity a year, costing only £46. An ‘A’ rated one would use around two-thirds of the electricity – a saving of £15 a year.

Vacuum cleaners

Vacuum cleaners might make a lot of noise, but they don’t pull a lot of power. A 1000w (1kWh) vacuum costs 28p per hour to use, so there’s no need to resort to the dustpan and brush just yet.


TVs are rated by the amount of power they consume in 1000 hours (which annually works out at just over two-and-a-half hours viewing a day). The bigger the screen, the more they consume: a 65 inch HD TV would cost £30 a year in electricity, while a 48 inch version might be more than a third less expensive.

OLED TVs don’t have a backlight, so use less energy than QLEDs and LCD.


How much does it cost to heat water at home?

Bath and shower

A bath holds approximately 150 litres of water, while a shower, on for 10 minutes, uses just over a third of the amount. Showers, it might seem obvious to say, are generally better for the environment in terms of water usage (dependant on how long you have the shower on for).

Showers are also better for your bank balance too; a bath needs about 1.5 kW of energy to heat the water up, costing approximately 42p a time. If your household has two baths a day, that’s more than £300 a year. The same number of showers will cost around £100.

Invest in a water efficient shower head if you really want to cut down. They do the same job after all – and the savings will round up in no time.


A boiler in a medium-sized house with average usage of 12,000 kWh would use £975 of gas at the current market rate of 7.3p per kWh, plus 27p per day standing rate.

Make sure you have a modern condensing boiler, as they are much more energy efficient. Use a smart meter too, so you can see when you are using more energy – and what appliance is consuming the most power.

Hot tubs

If you think baths are expensive, then perhaps, a hot tub isn’t for you. Experts What Spa? estimate a hot tub costs around £1 a day to run. However, that figure was based on energy costs pre-March 2022 where costs have since doubled. This means a hot tub could work out to cost at least £730 a year to run.

Keep your hot tub in a sheltered spot to avoid wind and rain cooling it and turn the heat down to below 37 degrees to reduce consumption. Also, cheaper models are usually less well insulated.


How much does an electric car cost to charge?

Many people are now switching to electric cars from petrol and diesel and charging them at home. It’s a big expense, compared to most other household appliances: a Tesla Model 3 with a 70 kWh battery would cost nearly £20 to charge every time and then has a range of about 280 miles.

But it’s considerably cheaper compared to a petrol or diesel car, which at current fuel prices, often cost five times more to fill and are able to go twice as far.

To make it even more efficient, set the charger to come on at night, when off peak electricity is cheaper, and ‘precondition’ your car before you set off – warming the cabin and the batteries using the cable attached to the house. It will go further on one charge.

Because we play by the book we want to tell you that…

Your home may be repossessed if you do not keep up repayments on your mortgage.
There may be a fee for mortgage advice. The actual amount you pay will depend upon your circumstances.
The fee is up to 1% but a typical fee is 0.3% of the amount borrowed.
