Council tax band challenge

[Rojo019]

Hi has anyone challenge a council tax band and if so what was the outcome and is there any advice?

Just looked on my own street and the 2 bed semi detached properties which have 2 double bedrooms around 20 years old are C bands. The 3 bed semis are D bands so times have changed and more is being charged, no surprise there.

Successfully changed the banding on a new build that we rented. I provided data of banding of similar properties and data on how much the place should've cost in 1991 based on current value and historical values of similar places.
It was very obviously in the wrong band, think was D or E from memory (15 year ago) when it should have been B or C.

I have a feeling that our London council of the time had quite the habit of overhauling new builds.

Before council tax when it was rateable value, we challenged ours as it was for house and garage but the garage had been knocked down before we bought it. An assessor came out and said the amount stood as we now had central heating which was not accounted for before. Seems you can’t win if you improve your house.
