Council Tax - Change of circumstances
The law says you must tell us if there is any change to the
information we have used to decide whether you are entitled to
Housing Benefit or Council Tax Benefit,or both.
You should tell us immediately, in writing, of any changes in
your circumstances.
You should tell us straight away even if you are still waiting
to hear from us about your claim, and even if you have already told
someone else like the Department for Work and Pensions or your
landlord.
