Water advice

Domestic water usage

The biggest use of hot water in the house is usually baths, showers, dishwashers and washing machines.

Water usage facts

  • running a bath will typically use up to 88 litres of water to fill. If you were to have two baths a week, it would cost you £37 a year.
  • running a shower will typically only use 56 litres for 8 mins and 24 litres for 4 minutes
  • If you were to have 8-minute showers every day, it would cost you £80.11 per year. If you were to have a 4-minute shower every day, it would cost you £40.06 per year.

Shower Heads 

Save money by replacing leaky faucets with new, energy efficient shower heads. New high-efficiency showerheads use less water than standard models without sacrificing performance, helping you conserve water and save on energy. With a low flow shower head, you can reduce this to 4 or 5 litres/minute.

Top Tip!
Have shorter showers. If everyone in your household shaved just a mere 60 seconds off of their shower times, you could save over £20 a year!

Washing Machines

The quantity of litres used in a wash load varies depending on the model. As a general rule of thumb, modern washing machines out there use around 57-95 litres of water per wash. 

Energy Efficiency Labels

If you’ve gone shopping for electrical appliances recently, chances are you’ll have spotted one of these. EU energy efficiency labels are found on a selection of white goods, including:

  • Washing machines
  • Tumble dryers
  • Fridge-freezers
  • Dishwashers
  • Electric ovens
  • Energy-saving light bulbs 

The label is there to give you information about how energy efficient a product is. Product ratings go from D up to A+++, with A+++ beingthe most energy efficient. The label also includes the annual energy consumption for each product, as well as product-specific information, such as noise levels or water consumption.

Don’t overfill the kettle 

Heating water is an expensive process and uses a fair bit of energy. Solution? Only fill the kettle up with the amount of water you intend on using. If you boil 1 pint more than you need, 4 times a day, it could cost you around £10 extra a year in energy costs.
