Monitoring fuel quality across our supply chain
Comprehensive and effective procedures are used to monitor and control the quality of the fuels we supply.
In the event of a quality concern, we can trace every litre of fuel back through our supply chain, to identify the truck, loading rack, tank and ship it came from, so we can rapidly identify root causes and respond appropriately.
About our quality checks
Any product which we buy into one of our terminals is tested before it enters any of our tanks. We retain product samples.
Independent inspectors test our fuel before it is released for loading onto a road tanker, to verify that it complies with our sales specification and with the relevant quality standard - EN 228 for petrol and super unleaded, EN 590 for diesel or EN14214 for biodiesel. These test results are published on this web page.
Strict procedures are in place to prevent fuel stored in a tank in one of our terminals from being contaminated as a result of incorrect pumping activity (cross-overs).
Formal service level agreements with all our terminal operators cover communication and quality control.
Monthly testing for water and microbiological activity in diesel tanks takes place at all the terminals where we store fuel.
Supporting our customers
on quality matters
We aim to exceed the expectations of our customers through a combination of leadership and proactive, preventive action.
We pride ourselves in the quality of support we provide to our customers if there is a problem at one of their sites.
We are quick to send our own experts to site when necessary, to carry out formal investigations or assist with corrective and preventive action.
A formal quality
under ISO 9001
We have a formal quality management system covering the movement of fuel from load point to our customer sites.
The system is certified to ISO 9001 and includes extensive product quality controls.
The system requires quality inspections of our fuel at each point of our supply chain. We also have formal procedures and service level agreements with all our terminal partners.
By driving continual performance review, our quality management system provides a formalised framework through which to respond to changing customer, industry and statutory requirements. It allows us to share information quickly and effectively with our stakeholders.
