wondered if they were more often than not dodgy, and how
Not dodgy, they just use people's laziness and ignorance to generate a margin by paying less than you'd get from a breaker or metal recycler. If they're paying you money, they're recouping it plus their profit by selling the thing on to a breaker or metal recycler. The dodgy end of disposal is people who want paying to take stuff away, you need to do your due diligence on them if you don't want your rubbish to be fly tipped.
Lamp post.
