Hmm, looks as if the service provided in my area, Stockport Council, is very good value for money! However, I think the green bin collections are regularly debated at council meetings and alternative provision such as only having the collection every two weeks rather than weekly as now, or having an extra charge for those who want a collection might well be introduced.
As all our food waste also goes in the green garden waste bin there is always a huge outcry at the prospect of only fortnightly collections, especially in the summer months.
I actually have two green bin, the second one cost me £15 I think but is collected weekly at no extra cost if I put it out. It’s only used a couple of times a year though after my gardening service has done the pruning!
