I help in a local charity shop, (all the money stays in our village). Yes we want your stuff! What you call tatt someone else thinks is lovely. I am amazed at what people will buy. There is a list of things that most charities won't take: duvets/pillows, safety equipment - so no bike helmets etc. some won't take pushchairs, we do but check the brakes and obvious wear and tear, electrical equipment as it all has to be tested which is usually more than the item is worth, ask about this as some charities have someone that does it for them. Most shops also take clothing/ bedding/towels etc that has seen better days to sell for recycling. We can also sell shoes/handbags/soft toys without the ce. mark for recycling. Some of the larger charities can take old books for pulping as well. Hopes this helps with your clear outs.
