Zambian Kwacha is not supported by the regular travel currency exchanges or the UK postal office. You may want to try one of the larger commercial banks or major hotel chains, but you should probably expect the same result. If they do agree to accept your currency - expect significant fees.

The Zambian kwacha is too minor and inflationary for most companies in the UK to want to deal with. Your best bet would probably to reach out directly to the Zambian community in the UK via groups like Zambians Together, they can either point the way or you can find somebody to negotiate a private exchange with. Although I'm afraid that living in Bristol instead of London will complicate things.
