Tea time

Don't boil-over

Whether you're a devo-tea of a builder's brew, coffee or hot chocolate, it's time to put your mettle to the kettle. We are a nation of tea addicts, there's no denying it. We glug down about 165 million cups of tea a day, and 70 million cups of coffee, yet 2/3 of us boil far more water than we need.

Only boil what you need – any extra and you’re wasting time, money, and valuable energy.


Here's some great reasons why it's so important.

You could save £7 a year from your electricity bills by only boiling what you need.1Every little bit helps!


A watched kettle never boils… especially an overfilled one. Why wait around for water you don't need to boil when you could be sitting supping a beautiful beverage?

30 million

litres of water are boiled every day in the UK only to go cold again.2

Climate change

Pretty straightforward really: unnecessary boiling = wasted electricity = easily avoidable carbon emissions.


It's not rocket science, just fill the kettle with what you need.

  • Do the tea call before you boil – check how many people you’re making for (and pick up brownie points while you’re at it).
  • To save you measuring the cup each time, why not draw a marker on your kettle (if it doesn’t already have one) showing how much is needed to fill your favourite mug?
  • Buy an energy efficient kettle making it nice and easy for you to only boil enough water for what you need. The Ethical Superstore have some great options.

I now don't waste any water or extra electricity and it always is the little things that make a difference!

This is a good one - simple and easy to implement, not one I'd ever thought of.

This one went brilliantly. I pour water into my mug then into my kettle. I only boil what I use. :) Now I need to get better at using less water when I do my dishes. I use a basin, but I wonder what strategy I could still use to use less water... THANK YOU!

It was so easy to do, and it has made me think about water & energy use much more.

Rather than just filling kettle without thinking, it made me aware of how much I really needed.

Took a little while to break the habit of always having a full kettle but now conscientiously check beforehand to make sure I am only boiling enough water that is required.
