About red diesel disposal in Johnstown Carmarthen

Two clocks run on stored red diesel at once. Like any diesel it ages, waters and bugs; unlike white diesel, it also carries a rebate marker that HMRC takes seriously, so both the fuel and the paperwork have to be dealt with cleanly.

The 2022 change is the reason for a lot of these calls. Sectors that lost the entitlement — construction, plant hire, many commercial users — were left with red diesel they could no longer put in a machine, and the compliant answer is removal and documented disposal.

Safe disposal routes the red diesel to a licensed facility for recovery or destruction and documents it, so the duty of care sits with a paper trail rather than with you guessing.

Disposal is where duty of care bites. Under the rules the waste is yours until it reaches a permitted facility, so the transfer note issued in Johnstown Carmarthen — recording what left, when and where it went — is the document that keeps you covered if it is ever questioned.

Common questions

Do you dispose of red diesel in Johnstown Carmarthen?

Yes — across Johnstown Carmarthen and the rest of Carmarthenshire. A registered carrier attends home, farm, depot, marina and commercial sites, pumps out the red diesel and issues a waste transfer note on site.

Can you clear a tank so it is dye-free?

We remove the red diesel and can clean the tank so it is fit to hold road diesel again. Any residual dye is dealt with as part of the tank clean.

Will I get paperwork for HMRC?

You get a waste transfer note recording what was collected and where it went. That is your evidence of compliant disposal for both HMRC and the regulator.

Do you take contaminated red diesel?

Yes — rebated fuel spoiled by water, sludge or bug is collected and disposed of the same way as any contaminated diesel, with documentation.

How is the price worked out?

Per litre against the volume and access, quoted before travel. Give us the rough litres in the tank or bowser when you call.
