We moved in in September 2004. Every March thereafter, rather than continuing on two months notice, we started a new lease, 12 months at a time. the original rent was 440, and it went up to 460 on the first renewal in March 2005. Every year after, we started a new 12 month lease, for our own security. Our last 12 month lease started in March 2014. We were served notice in January 2015 and vacated April 2015. For all I know every new 12 month lease has had 460/month on it, but I don't have the old ones any more. The last lease definitely does have 460/month on it. Every year we have been told to "add £10 on to the rent" but usually always by phone. So last year I have paid £570/month. Now I check the lease and it actually says £460... The deposit is held with mydeposits.co.uk. I'm fairly sure they notified us, I remember some leaflet being sent.
