Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
Yes you do; never forget Benjamin Franklin's dictum that in like there are but two certainties, death and taxes! Here is the Government UK's guidance on Council Tax:
You’ll usually have to pay Council Tax on an empty home, but your council can decide to give you a discount - the amount is up to them. Contact your council to ask about a discount.
Your council can charge up to 50% extra Council Tax if your home has been empty for 2 years or more (unless it’s an annexe or you’re in the armed forces).'
I need not remind you that these days Councils are strapped for cash.
I am so sorry to have to rain on your parade.
Thank you for your support.
