This guide explains the problem in plain English first, then shows you the next practical step when you are ready.
You are setting up a new tenancy and you do not want to rely on an old template. This guide explains which agreement you need and what to sort before the tenant moves in.
Follow the Rules
Failing to follow correct procedures means your rent increase is not valid. The contract-holder can continue paying the old rent until you serve a proper notice.
Rent Increase Rules Overview
The Renting Homes Act provides a structured approach to rent increases for standard occupation contracts. Key rules include:
New tenancy
Need the agreement sorted now?
Use the right agreement for the property now so you are not fixing an old template later.
- Choose the right England agreement route for the tenancy you are setting up.
- Avoid old wording that causes problems later.
- Preview it before you pay.
- You must give written notice using the prescribed form
- Minimum notice period is 2 months
- You can only increase rent once per year
- The increase must be to a "market rent"
- Contract-holders can challenge excessive increases
Notice Requirements
To increase rent, you must serve a written notice that includes:
- The current rent amount
- The proposed new rent amount
- The date the new rent takes effect
- Information about the contract-holder's right to refer to a tribunal
Use the Correct Form
The notice must be in the prescribed form. An informal letter or verbal notice is not sufficient. Use the Welsh Government's standard rent increase notice.
Notice Period
You must give at least 2 months' notice before the new rent takes effect. The new rent cannot take effect earlier than 12 months after:
- The start of the occupation contract, or
- The last rent increase (whichever is later)
Frequency Limits
There are strict limits on how often you can increase rent:
- Periodic contracts: Maximum once every 12 months
- Fixed-term contracts: Only if the contract allows it
Contract-Holder Rights
Contract-holders have rights when it comes to rent increases:
Right to Challenge
If the contract-holder believes the proposed rent is above market rent, they can refer the matter to the Residential Property Tribunal Wales. The tribunal will determine the appropriate market rent.
Time Limit
The contract-holder must make the referral before the rent increase takes effect. If they miss this deadline, the new rent becomes payable.

What if the tenant doesn't pay the increased rent?
If you've followed the correct procedure and the contract-holder hasn't challenged the increase, they must pay the new rent. Non-payment would be rent arrears, and you could seek possession.
Can I increase by any amount?
The increase should be to market rent. If you try to increase to an unreasonably high amount, the contract-holder can challenge it at tribunal. Research comparable rents in your area.
What about fixed-term contracts?
You can only increase rent during a fixed term if the contract allows it. Otherwise, you must wait until the fixed term ends and the contract becomes periodic.
Can we agree a different increase?
Yes. You and the contract-holder can agree to vary the rent at any time by mutual written agreement. This doesn't require the formal notice process.
