Whereabouts? I have a friend who lives in Carloway.

Can't comment on Scottish fuel sources but nearly all the kerosine supplied around East Yorkshire and Northern Lincolnshire is refined in Lindsey Oil Refinery. All the different companies fill their tankers there. Some add magic juice which they claim makes their Kerosine better than their competitors but it's all refined the same way. I'd be surprised if Scottish refineries run different batches for different companies and water in the refinery output stream is extremely unlikely. Most times we found water inside domestic fuel tanks it was due to rain ingress through defective tank tops or "borrowed" fuel being poured in by the customer. I had one old chap whose boiler wouldn't fire. I drained about 5 gallons of water out of his steel tank and purged the fuel lines to get his boiler going. Placed a poly cover over the top of the tank as a temporary rain proofing as I found the top had been dished in by him standing on it to access his garage roof and clean his bathroom window. Over the years a pool of rainwater formed and eventually a hole rusted through, funneling rain into the tank.
When he had run the tank contents right down over the rest of the season I swapped his old tank out for a new one.

Yes. We've always made a point of keeping a good amount of fuel in the
tank.
