How do I increase the rent legally in England?

For an assured periodic tenancy you can increase the rent once a year, not in the first year, by giving the tenant at least 2 months' notice on a completed form 4A. This is the section 13 process. The tenant can apply to the First-tier Tribunal if they think the proposed rent is above the open market rent.
