Ok, in the States when you donate household goods to a charity shop, you are given a receipt. It's up to you to value the items. (There are some guidelines available, though.) Once you have valued them, you can apply for a credit on your taxes for the donation.
So I know there is something vaguely similar at play here in the UK. But what I'm seeing is that a charity shop has to agree to take the items and sell them for you and then you agree that they can keep the profits. That seems like an awful lot of record-keeping for the charity shop! (?) And it would be more appropriate for more expensive items than typical household goods. I have some dishes, a stand mixer, a microwave oven, a couple of oil-filled room heaters, stuff like that, that I was hoping to donate. I was also going to donate our living-room furniture to an organization that helps refugees get settled, as it's only a couple of years old and in very good shape. I'll be donating the goods one way or the other, but if I can get a tax credit for them I would certainly be able to use the money.
Am I understanding the UK tax credit thingy correctly?
