This comes into effect in April 2017. In essence, if you want your green waste collecting it will be done fortnightly but it will cost a yearly sum if you don’t register then your green waste will not be collected as of April 2017.
There is a comprehensive Q & A page but there are no concessions that I can see. You can attend the recycling sites such as the one in Carnforth for free, however, if you do not drive and therefore do not have a car then you must pay for green waste collection, not sure how green efficient it is to drive on a 24 mile round trip. Oh and the fee is per bin and not per household, so you can share a bin if you like. They will not pick up surplus green waste alongside your bin if it is full when they collect. Thanks.
