Tankful for business
Green diesel and heating oil for farms
Tractors, loaders, the dairy and the farmhouse. Send one brief and local oil suppliers quote for the year, not just the next fill.
- Silage and harvest weeks when the tank can't run dry
- A delivery that fits around milking and yard access
- Separate green diesel and kerosene on one account
What your fuel costs you a year
An estimate from today's household price for 1,000 litres across Ireland. Commercial volumes are usually quoted lower.
- About 8,000 litres a year
- €13,024
- Each 1c a litre is worth
- €80/yr
- 3c a litre better
- €240/yr
Typical farms use 4,000 to 30,000 litres a year. Oil suppliers sharpen their price when they can see the whole year, not one fill.
Reference: €1,628 per 1,000 litres of heating oil, VAT included. Green diesel and road diesel are priced differently.
Green diesel or road diesel: what a farm can use
Green diesel is marked gas oil: diesel carrying a reduced rate of Mineral Oil Tax, on condition it is only used for qualifying purposes. Revenue marks it chemically and dyes it green so misuse can be detected.
On a farm that means tractors, loaders and other agricultural machinery working off the public road, and heating. A jeep, pick-up or car driven on the road needs road diesel, even if it belongs to the farm. Revenue can detect the marker in a vehicle's tank and seize it.
- Keep green diesel and road diesel in separate, clearly labelled tanks
- Ask for separate lines or invoices for marked gas oil, kerosene and road diesel
- Buy marked gas oil only from a licensed marked fuel trader
Green diesel tax changes in 2027
Budget 2027 set out when the temporary tax relief on marked gas oil ends. If you have tank space, filling before each step can save on that load. Prices still move with the oil market, so a rise in tax does not guarantee a higher delivered price on the day.
- From 28 February 2027: Mineral Oil Tax on marked gas oil of 21.95c a litre, before VAT. Marked gas oil's non-carbon rate (5.4c a litre including VAT) is restored in full.
- From 1 May 2027: Mineral Oil Tax on marked gas oil of 23.98c a litre, before VAT. The deferred marked gas oil carbon increase takes effect.
Getting a better price on farm fuel
Oil suppliers price a farm that buys 15,000 litres a year differently from one that rings for 1,000 litres when the tank is low. A brief showing the whole year, your tank sizes and when you need deliveries lets them quote a sharper rate per litre and plan deliveries around silage and harvest.
- The price per 1,000 litres, with and without VAT, and how long the quote holds
- The minimum delivery and any delivery or small-drop charge
- Payment terms: card on delivery, direct debit, or a credit account on 30 days
- Whether they offer a fixed price for a period, and what it costs to fix
- Guaranteed delivery during silage, harvest and calving
- A separate price for heating oil for the house and yard
Storing fuel safely
Building regulations guidance (TGD J) calls for a bunded tank for oil stores over 2,500 litres, and where a leak could reach a watercourse or drain. A lockable fill cap, a tank alarm and a sight of the tank from the house help against theft, which is common with green diesel.

Questions businesses ask
Can I use green diesel in my jeep or pick-up?
No. Marked gas oil is only for qualifying uses such as farm machinery working off the road and heating. A vehicle used on public roads must run on road diesel. Revenue tests vehicle tanks for the marker and can seize vehicles and fine the owner.
Why is green diesel cheaper than road diesel?
It carries a lower rate of Mineral Oil Tax because it is restricted to qualifying uses like agriculture and heating. Revenue adds a marker and green dye so misuse can be detected.
When does tax on green diesel go up?
From 28 February 2027: Mineral Oil Tax on marked gas oil of 21.95c a litre, before VAT. Marked gas oil's non-carbon rate (5.4c a litre including VAT) is restored in full. From 1 May 2027: Mineral Oil Tax on marked gas oil of 23.98c a litre, before VAT. The deferred marked gas oil carbon increase takes effect.
How much green diesel does a farm use a year?
It depends on the enterprise. A typical dairy or drystock farm might use 4,000 to 10,000 litres; tillage farms and farmers doing their own silage or contracting can use 20,000 litres or more. Enter your own figure in the estimate above.
Can I get green diesel and heating oil on one account?
Usually, yes. Most local oil suppliers that deliver marked gas oil also deliver kerosene. Tick both fuels in your brief and ask for separate invoice lines.
How much does it cost?
Nothing for your business. Oil suppliers that win an account through Tankful pay Tankful, never you, and paying never gets a supplier in front of a better local match.
Will I be bombarded with calls?
No. Your brief goes to at most 3 oil suppliers that deliver to your area, and only they get your contact details.
