The last time rent was put up for this tenancy to £500 was on 3rd March 2008. Those tenants moved out and new tenants took over the tenancy on 1st October 2010 paying £550. Can we send a section 13 to increase the rent as of 1st November 2011 to £650?

On the section 13, question 3 asks ‘The first rent increase date after the 18th April 2003 is’:WHAT WOULD I PUT HERE.

On section 13, question 4 asks ‘The starting date for the new rent would be’: 1st November 2011????

Thanks for your help
