Hmm, I must agree though, £1 per mile delivery isn't cheap... at a max motorway speed of 70mph, thats £70 per hour driving, (and roughly 15 mpg for a ford transit van, thats 15 miles per 3.8 litres, which is 15 miles per £3.2 pounds (fuel at £.86 per litre). Hence, london being roughly 120miles away, the fuel cost using a ford transit van, would be roughly £25. Hence, the personell (driver) is being paid £95 for a 4 hour drive (120miles each way at an average of 60mph). Which implies the driver is being paid roughly £22 an hour.
So, considering their fuel costs £25(to london) and their driver £22(per hour)... I'll let you draw your own conclusions... I'm not sure what wages are like for drivers, but as a professional qualified engineer (having done 4 years of college), I earn £35 an hour....
