Red Diesel use for Boat Propulsion
Discussion
As someone with a petrol boat looking to upgrade to a boat which is probably diesel powered can someone please explain. This is for use in England, not NI or mainland Europe.
I understand that the rules changed in April this year but what I read online is confusing.........
But then why does it then go on to say:

Although entitlement to use red diesel and rebated biofuels is changing from April 2022, this does not alter the arrangements for pleasure craft in GB as ‘fuel for all marine craft’ remains a qualifying purpose and that includes propelling private pleasure craft in GB
So propuslsion on a pleasure craft qualifies for red diesel use?But then why does it then go on to say:

Red diesel continues to be available at the waterside in GB but recreational boaters must pay the full rate of duty when purchasing fuel for the purposes of propulsion.
Confused.

I am no expert, but I read, “qualifying purpose” as qualifying for duty, and that seems to be backed up by the second RYA extract.I understand that the rules changed in April this year but what I read online is confusing.........

I may be wrong, but my understanding is that red diesel is available at most marine fuel pumps as commercial operators can purchase it at reduced duty rates, and recreational operators can purchase it at full duty for propulsion only (or a split, like 60:40 with reduced duty on one part of the split when it is used for heating the boat and for propulsion)I understand that the rules changed in April this year but what I read online is confusing.........

So rather than limiting your fuel pump to one market, the correct duty can be applied instead.
Hope that makes sense.

Yes, quite right, 60/40 split for propulsion/heating. That said, I know of many people who buy it at that split rate who don't even have a diesel heater or calorifier. Not that HMRC are likely to come knocking.So rather than limiting your fuel pump to one market, the correct duty can be applied instead.
Hope that makes sense.
However the sad reality that with fuel prices recently it's sometimes not been any cheaper than garage forecourts!

So what you are saying is that there are varying rates of taxation of red dependent on end use?
So I go along, tell the chap i'm using it for whatever is at the lowest rate, then use it in something which demands the higher rate?
That doesn't sound right....
If it's for heating the rate is lower. When I buy diesel at a marina (inland not coastal if that makes any difference), as far as I know it's the same stuff as road diesel, but then they will ask 'What split do you want?' And you have to sign a bit of paper.So I go along, tell the chap i'm using it for whatever is at the lowest rate, then use it in something which demands the higher rate?
That doesn't sound right....
Despite that, it's still more expensive than road diesel, probably because marinas can't buy in bulk like garages.

This signing of a bit of paper is pretty useless too.....

In essence, yes. But it works both ways, you could be a marina liveaboard going nowhere for the winter, and even though both your engine and your heater share the same diesel tank, you'd still only be able to buy it at a 60/40 split.So I go along, tell the chap i'm using it for whatever is at the lowest rate, then use it in something which demands the higher rate?

It's not a "fiddle" or anything dodgy, it's just the way things are and all above board. I suppose if you physically don't have a diesel heater installed you may be on thinner ice, however if you are heating your water from the engine and own a hot water bottle, you're probably OK anyway!
Seriously, HMRC have bigger things to worry about than slightly to wrong rate of duty paid on 60 litres of diesel in someone's boat...

Household heating fuel is different stuff, it's 'white' and is different to road diesel.

You may be right on both counts, but as the owner of a diesel-engined boat I can tell you that's the way it is.This signing of a bit of paper is pretty useless too.....
The bit of paper is probably useful to the marina as supporting data for their VAT return.

Yes, it's a complex joke.
If you should take your boat to euroland, you can be fined a lot of money for having the 'red' dye in your tank.
My boat does not get through huge amounts of diesel. It's a small yacht with a 20HP inboard. And a blown air heater.
I run it on white bought from the forecourt.
There are issues with storing diesel for long periods due to bio content and 'diesel bug', so this time of year I put some of the boat's store of diesel in the car.

It is a joke, everyone is going to buy at the cheapest rate as it can't be proven otherwise.
I get my red from a marina, I've never been asked for ID, have only been asked to fill in a form once (and I could have written anything on it) and have no idea what rate he's selling it at.
So basically I need to tell him it's for heating, at what rate is that?
According to this by HMRC:
https://www.gov.uk/government/publications/reform-...
Gas oil (diesel, red) 'Used in an excepted vehicle, machine or appliance, other than for heating' is the same rate as 'Used in an excepted heating machine'. Both being 11.14p.

Why not present the HMRC info to your marina and ask them what their rates are?I get my red from a marina, I've never been asked for ID, have only been asked to fill in a form once (and I could have written anything on it) and have no idea what rate he's selling it at.

I don't bother; you can hardly say 'That's a bit pricey' and take a 4-hour trip to the next marina to save £1. Just buy the stuff and try not to think too hard

Apparently you're OK provided it's in your main tank rather than spare cans in the locker and you've got some receipts showing VAT has been paid on it. If you should take your boat to euroland, you can be fined a lot of money for having the 'red' dye in your tank.
I don't know if there's any shore side fuel berths in the UK selling white diesel and if that's the case filling a bigger boat up with white from dozens of cans off a forecourt if you're going abroad would probably start getting a bit silly.
And even if you do use white diesel traces of red die can stay in the fuel system for some while after your last tankful of it.

I have checked with my marina today about the issue of supplying fuel for a 'declared' domestic use only (no propulsion), and they have no problem as it is the boat owner who is making the HMRC declaration by signing the fuel receipt which they forward to the Excise boys, and it will be you on the hook if HMRC wish to check. Probably would get away with, say, 100ltr to last a year, but I reckon HMRC will come aboard if you are running through that amount or more, for a day trip and are topping 1000ltr plus per year?
Want to risk a fine and the possible loss of your boat?? Your decision...

Mine pre-empts any personal declaration by stating they tax fuel on a basis of a 40/60 split between heating and propulsion. If you don't have diesel heating and unless you 'fess up when you go to the office to pay then by default you're not paying the correct amount of tax on 40% of every litre you buy, but in my case and given a 25l tank will last me several weeks I'm rather hopeful HMRC's operatives might have better things to do than turn up mob handed for a nose round my bilges.
As an aside to all this malarkey my son pays £1.44 a litre for red diesel for his narrowboat but my marina charges £1.79 for exactly the same fuel.

It's for the duty rather than Vat. But yes heating use is duty free. That said it took over a year of asking for HMRC to send us a duty return last year and this year they reverted to sending it to someone who hasn't dealt with it over over 5 years so don't expect them to check any boats! Mind you we only sell about 2000l per year so hardly big!

Yep, a 60/40 split is the norm unless you declare your boat is commercial or it's only for domestic use (liveaboards?). My marina has quite a few commercial vessels refuelling including fishing boats and a Border Force cutter, as we have a high speed pump as well as the normal 'forecourt' type of pump both delivering 'red' from the same tank.If you don't have diesel heating and unless you 'fess up when you go to the office to pay then by default you're not paying the correct amount of tax on 40% of every litre you buy, but in my case and given a 25l tank will last me several weeks I'm rather hopeful HMRC's operatives might have better things to do than turn up mob handed for a nose round my bilges.

Interesting you should mention cost of diesel supplied on the canals. I had a quick google and found an amazing disparity in costs up and down the cut some of which, are equivalent to, or more expensive than, my marina charges!
