Reviewed by [**Rambo S** ](/editorial/), Wrong fuel expert, Fuel Fixer · last checked 1 November 2026 ## About red diesel disposal in Llanishen Cardiff The dye in red diesel is the whole point of it: it marks fuel that has paid less duty because it is meant for agriculture and a few other off-road uses. The 2022 rules narrowed those uses sharply, so stock that can no longer be used has to be removed by someone licensed. 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. Once lifted, the red diesel is disposed of through a licensed route — recovered where it can be, destroyed where it cannot — and every step is captured on the waste transfer note you keep. The compliance value of proper disposal is the record. The fuel leaves Llanishen Cardiff for a permitted facility, and the transfer note captures the movement — the difference between disposed of and merely gone. ## Local Welsh red diesel disposal in Llanishen Cardiff: the facts Fuel | Red diesel | Service | Collection and licensed disposal | Council area | Cardiff | Postcode districts | CF14 | Why it degrades | Ages like diesel, plus a legal marker dye that stains tanks | Typical sources | Farms, plant, generators, bowsers, decommissioned tanks, closing businesses | Classification | Hazardous waste — waste transfer note issued | Regulator | Natural Resources Wales | Typical cost | Quoted per litre or per job | Attendance | Collected and disposed of under licence | Helpline | 01295 380724 | ## Where red diesel comes from around Llanishen Cardiff Across Llanishen Cardiff and its surroundings we collect and dispose of red diesel from estates and large gardens clearing old gas-oil stock from mowers, generators and heating plant.

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. ### Other sites in this network Fuel Fixer Wales is part of Stockbridge Capital Holdings › Fuel Fixer International › Fuel Fixer Ltd.
