It's been an unusual month at work due to sporadic access to my 'read-only' council tax records and my realisation that I really do rely on regular access to this data for my empty homes work.
Like other councils, this reduced access to council tax data is due to the annual billing and the roll-over programme into the new financial year. I'm lucky to have a good relationship with my council tax colleagues. I didn't realise they have to check the bills first, starting with the business rates bills, then the council tax bills. And they have to check all the exemptions as well.
