The fuel delivery procedure and what it costs
A roadside fuel delivery delivers 5 to 10 litres of the correct grade of fuel (petrol or diesel, the operator confirms the fuel type from the vehicle registration before leaving base). The fuel is carried in an approved container compliant with the Petroleum (Consolidation) Regulations 2014 and the HSE's DSEAR guidance.
The decant is performed with the engine off, the vehicle in a safe position, and hazard lights on. The operator confirms the fuel accepts the decant (fuel gauge rising, no fuel-cap overflow) before confirming the vehicle is ready to start. The cost is the roadside-assist band, see the pricing page, which covers the operator's time and the fuel cost at the current pump price.
The delivery gets you to the next forecourt; it is not a full tank. Drive to the nearest petrol station and fill up before the delivered fuel runs out, 5 litres at typical motorway consumption (8 to 10 litres/100 km) gives you approximately 50 to 60 km of range.
