What this means
This instrument starts blank so it does not judge a made-up example before you have entered your own situation.
Formula used
Checks notice period against jurisdiction minimum, months since last increase against permitted frequency, and (where applicable) percentage increase against RPZ or stabilisation zone caps.
Worked example
An England tenant given 2 weeks' notice of a rent increase after only 8 months has two procedural problems: insufficient notice (minimum 4 weeks) and too soon since the last increase (minimum 12 months).
Common questions
What is a Rent Pressure Zone (Ireland)?
RPZs are designated areas in Ireland where rent increases are capped at the lower of 2% per year or the Harmonised Index of Consumer Prices (HICP). Most of Dublin and Cork are RPZs.
Can my landlord increase rent during a fixed-term tenancy?
Generally no — in England and most jurisdictions, rent cannot be increased during a fixed term unless there is a specific rent review clause in the tenancy agreement.
