How much !!! Why is everything so expensive on The River Thames?. There must be a reason… This is probably the cheapest diesel we have seen ,but also look at the price of the petrol. Most of the red diesel down here is about £1.20 per litre self declaration although I did contact the local fuel boat who said he charges between 80 and 85 pence per litre. The last time we bought diesel on the Grand Union Canal it was 59 pence from a fuel boat with Harefield marina selling it at 55 pence per litre which is half the price. It’s a good job we have a 300 litre fuel tank and hopefully it will last until we get back on to the canals.
Then at Henley the most expensive fuel we have ever seen .We have spoken to several boaters and they just say “well that’s Thames prices and you just have to accept it”. It won’t put us off coming back to the Thames in the future ,but my advice to any visiting boater would be to fill up with diesel on the canals and if you have any cans fill them as well.
