Our local tip had a deal with the neighbouring tip/s that allowed residents to use both - this was stopped due to 'costs', and now people in the north of my town, which covers all but 40 square miles, have to use our 1 'local' tip. which can mean a 15-mile round trip for me, and if traffic is mental, you can kiss goodbye to the best part of two hours. as opposed to 3 miles and 20 min round trip before!
You also now have to book in a timed slot, booked online, so you can't just turn up. The hours at the tip are also reduced. (cost saving) Most appointments are 8-4, which is no use to most people who work. And heaven forbid you have a plasterboard to get tipped. ; the staff are, on the whole, not helpful unless you're a 20 -30-something slim woman, or they think it may be valuable. In which case, they'll swarm you.
Still, this is not an excuse for fly-tipping. I reckon most is done by trades or the very dodgy, 'we'll get rid of your rubbish for £20' types. who are used by the very people who can't get to the local tip for all the above reasons.
This reminds me, I was helping a friend tip some stuff a few years ago (pre Covid) who didn't drive, and his tip was charged for slabs. I'd left my wallet on his kitchen table, and this was before I fell in love with Apple Pay. A very kind chap, whom I'd never seen, paid the few-pound charge; mental.
