Yes. Once a year your rent goes up at the rate of inflation which is set by the government and is usually talked about as a percentage.
Imagine the rent in your first year is £1,000 per month. If inflation is 3% then the rent in your second year would be £1,030 per month. This is predictable and manageable.
But, if you ever feel like your rent has become higher than the rent for similar homes in the same area, ask us for a rent review. You can do this every 5 years if you like.
