No wonder my council charges the 4th highest council tax in the country, we still have a weekly collection for everything.*
I live alone, so generate a lot less rubbish than a family would. My non-recylable rubbish would barely fill a shoebox, so it wouldn't bother me if they started collecting 4-weekly, and I only put my recycling out every other week. The council here will happily give households a second recycling bin if they ask, and they come in (iirc) 3 different sizes, so you can ask for the biggest.
I suspect that this may change though. The food waste is now collected by a small electric lorry, not the regular binnies with the big truck. I see no reason why the non-recyclable, non-food waste shouldn't be collected fortnightly, and recyclable stuff isn't going to smell or attract flies unless people are putting tins etc in there unwashed.
My only gripe is that the compostable bags for the food bin seem to start to compost themselves in a few days, so often the bags split and all the peelings and stuff fall out all over the pavement. I double-bag mine, but it's not pleasant.
*For avoidance of doubt, this is a joke. I know that waste collection is a tiny part of the overall bill, and that it's adult social care and education that rightly get the lion's share of council tax.
