Industrial Heating Oil Delivered to Businesses and Commercial Buildings Across the UK
If you were using red diesel (gas oil) for commercial heating and lost access to rebated fuels from the 1st of April 2022 as a result of the duty changes, you need a cost-effective fuel to help keep your heating bills low. Industrial heating oil (IHO) is a drop-in alternative to diesel that’s made specifically for use in commercial boilers, dryers and heaters.
Please note that industrial heating oil is a fully rebated product and must only be used for heating. It is not to be used as fuel for a road vehicle, off-road vehicle, vessel or any other machinery that is not an excepted machine.

What is industrial heating oil?
Industrial heating oil (IHO) is specifically intended for use in commercial boiler applications for heat generation. Our aim was to create a product that’s exactly the same as diesel in terms of its physical properties whilst being a more efficient option for heating oil.
IHO is compatible with BS 2869 Class I, meaning it’s fully miscible with diesel, so there’s no need to run your tanks dry of existing fuel.
It’s one of the UK’s leading fuel products authorised for use by many of the top boiler companies.
