Anyone running a fridge?

After a basic idea of costs to run a fridge (pence per hour etc), frozen loads running around 6 hours per day.

How readily available is red diesel and what is it costing you? (never had to deal with purchasing red before!)

Any info and/or pointers appreciated.

it’s usually about 95p to 99p per litre.
plenty of places to get it from.
vat is 5% for the 1st 2300litres then anything above that and its 20%.
