No one had fuel so I asked a local boater.
Moored on the rings next to the newish pedestrian bridge at Cromwell Bottom. And walked 5 minutes up the hill to Oilswell.
They were super friendly, sold me Red for £1.10 a litre in barrells and gave me a trolley and a hand pump/syphon. Got two bag of coal as well.
Obviously the trolley system is not ideal but I've got a full tank now at a good price. Lovely people at the establishment who sold it to me when they were technically closed on a bank holiday.
