Ecover looks interesting. £2.50 for 950ml of washing up liquid (Lidl want 69-89p for 500-1000mL) and it's vegan-friendly. I hope the Method liquid detergent works well in cold water, I've found success with gel in the past.

@bonifartius Awesome. It's inexpensive and is readily available to me, I'll give it a try next time I'm low on washing up liquid.
