A post on this thread, from a former Yodel driver, dated November 2018, stated that he got paid 47p per delivery. Given that Yodel drivers are all self-employed, having to pay their own fuel and insurance costs (and possibly the lease charges on their vans as well), they need to do a hell of a lot of a deliveries in order to to make any real money from the job:

Self-employed work, but under a contract to a particular company, often pays far less than someone in a PAYE position would earn for equivalent work. When I was 'trade plating' (delivering vehicles across the country and having to hitch between jobs), I reckoned that I'd had a good week if I managed to achieve 60% of the National Minimum Wage rate. 40% was more usual and I once worked a 20-hour day, with no stops at all for food or drink, where (after having deducted the fares I'd had to pay out when there wasn't time to try hitching between jobs) I made the glorious sum of just one pound!
