Our neighbours on our left have slightly bigger or same size houses than us - both semi detached. Both similarly unremarkable properties. They are on a different road to us, but literally wall to wall with us. They are on band D, we are on Band E. I was about to challenge when I saw that bands are based on what houses would have sold for in 2003 and I can see that it would make our house actually band F. So there are 2 opposing arguments. Any one had any experience in making a challenge? I definitely don't want to end up worse off as our band here has put us in a bracket £100 pcm more expensive than where we were in our last home, a similar size, in London! (we are now south of the midlands). Thanks
