We have a strange situation in Northampton where with some items they go by how many. So rip out your old bathroom and you have a toilet, cistern, bath, basin and pedestal and your fine. Shower tray or bidet too, then you have more than six items and you have to pay! But take a hammer to the cistern and pedestal and put the broken stuff in a rubble bag or two and thats fine. Take out an old kitchen, flatten the units and thats OK, but take them down still built and you pay if there are more than 6 items.
