rubbish

Plasterer is coming this weekend to fix up this wall. I want to do whatever prep I can, especially around the wonky door. The wall is thicker next to the door than it is by the bath, and it is proud of the door frame by about 5mm on the left side of the door, but not above it. The right side...

So I know this isn't exactly an interesting topic but where I live in Ashford, Kent the council are now charging £6 per sheet or bag of plasterboard and £4 per sack of rubble/hardcore, plaster once set is classed as rubble so as you can imagine this is going to add up. Who knows of a better way...

So I recently completed a job for a customer, he has complained that I have left rubbish on the job(bags of bits of ceiling,coving, unused plaster/bonding etc) is it my responsibility to remove this rubbish? any help would be appreciated, thanks. Patrick
