E85 Sport,
The first year I would take my tanks to a station one at a time on my car hauler trailer. Then unload them with my tractor.
I live in rural Louisiana. Most farmers in this area have fuel tanks for their equipment so there are several wholesalers with trucks that deliver fuel. After the first year I got smart and now call a wholesaler and order a load of diesel. They send a truck that can hold 3,000 gallons of fuel. I am lucky and live about 4 miles from a refinery so the delivery charge is almost nothing when I am buying over 1,000 gallons at once. I actually have three tanks. My third tank is a small 150 gallon tank. I also have a Chevrolet 2500HD with a duramax that I installed a second tank in the bed. The truck can hold 88 gallons when empty. In theory, I can order over 1,400 gallons with the three fuel tanks and the truck. I have never ordered more than 1,200 at once.
I found that the best time to buy fuel is the second week in December or the first week in March. Fuel prices dip at these times of the year. Usually save $0.75 to $1.25 by buying my fuel at the low time of the year. I am not buying diesel this year. Diesel is so high, I am parking my diesel vehicles and am driving my gasoline vehicles instead. I have 5 vehicles and it is just my wife and me. We are retired and don't drive as much as we did when we were working. Before we retired we drove 250 miles per day to work. Now we don't need to fuel up but once per month (15 gal per month).
I don't think diesel fuel prices will drop for at least two years. Diesel prices are higher than gasoline because the oil companies are exporting 1.2 million barrels (50,000,000 gallons) per day of diesel fuel to South America and Europe per day. Yes per day. This is creating a shortage of diesel in the US which is why diesel fuel is so much higher per gallon than gasoline. I think this will continue until the next world wide recession and/or when the Ukraine war ends and Russia starts crude exports again. When diesel fuel prices drop in a couple of years, I will refill my diesel tanks and they will last me for years.

In the U.K. today I paid £1.71 a litre that’s $2.08 I think

If you are talking about British Pound Sterling to dollar conversion then you are paying $7.83 US dollars per gallon of fuel. The exchange rate from the pound to the dollar is approximately 1.21 dollars to the pound and there is 3.7854 liters per us gallon.
