When should you run the washing machine tonight?

Octopus Agile prices change every half hour. We find the cheapest stretch of the day so you can time your laundry, dishwasher and charging to the bottom of the market.

How it works

1

1. Pick your region

Great Britain has 14 grid regions, each with its own Agile prices. Enter your postcode to find yours.

2

2. Set your window length

A wash cycle takes 3 hours? An afternoon of baking takes 4? Adjust the slider and we instantly find the cheapest contiguous stretch.

3. Use the delay timer

Most washing machines and dishwashers have a delay-start function. Set it to begin at the start of the window and leave it — a cycle that overruns the window is still fine.
