Rent Increase Notice: A Practical Guide for UK Landlords | LegalDocuments.co.uk

Raising the rent is one of those decisions that feels straightforward until you start looking at the paperwork. Most landlords I speak with know they have the right to increase rent at some point during a tenancy, but far fewer feel confident about how to do it properly.
Get the process wrong and you can end up with a notice that simply doesn't take effect, or worse, a dispute that drags on through the First-tier Tribunal. This guide walks through the main routes a landlord can take to increase rent in England and Wales, what notice you need to give, and the points tenants can legitimately push back on.
It's written for landlords who want to stay on the right side of the rules without needing a law degree to get there.
What this document is
A rent increase notice is the formal way a landlord tells a tenant that the rent is going up. For periodic assured shorthold tenancies, the standard route is a Section 13 notice under the Housing Act 1988, served using a prescribed form (currently Form 4).
The notice sets out the new rent, the date it takes effect, and gives the tenant a chance to respond or challenge it. Not every rent change needs a Section 13 notice, though. If the tenancy agreement contains a rent review clause, the increase usually follows the mechanism written into the contract.
If the landlord and tenant simply agree a new figure between them, that agreement can be recorded in writing as a variation or a renewal. Section 13 is really the fallback for periodic tenancies where no other mechanism applies. What a rent increase notice is not, is a blank cheque.
The new rent has to reflect what the property could reasonably fetch on the open market, and tenants have the right to refer the proposed increase to the First-tier Tribunal (Property Chamber) for a decision.
How to use this document
- Check the tenancy agreement first. Before doing anything else, read the tenancy. Look for a rent review clause, the type of tenancy (fixed term or periodic), and any wording about when and how the rent can change. The agreement often dictates which route you need to take and will tell you whether Section 13 is even available.
- Decide which route fits your situation. If you're still in a fixed term with no review clause, you generally cannot force an increase until the fixed term ends unless the tenant agrees. For a periodic tenancy with no review clause, Section 13 is the statutory route. If both parties are happy to negotiate, a written variation is often the simplest path and avoids any prescribed form at all.
- Work out a reasonable new rent. The proposed figure should reflect market rent for a similar property in the same area. Look at comparable listings, speak to local letting agents, and keep notes on how you arrived at the number. If the tenant challenges the notice, the tribunal will look at market evidence, so having that homework done protects you.
- Serve the correct notice with the right period. For a Section 13 increase, use the prescribed form and give at least one month's notice for weekly or monthly tenancies, or a period matching the rent payment interval for less frequent payments. Annual tenancies require six months' notice. Getting the dates wrong is one of the most common reasons a notice fails.
- Keep evidence of service and follow up. Whether you post, email, or hand-deliver the notice, keep a record. If the tenant does not respond and the effective date passes, the new rent becomes payable. If the tenant wants to challenge it, they must apply to the First-tier Tribunal before the new rent takes effect, so be ready to justify your figure.

Common questions
Q How often can I increase the rent?
Under the Section 13 procedure, you can generally only increase rent once every 52 weeks. If your tenancy agreement includes a rent review clause, the frequency will be whatever the contract specifies. Increases agreed mutually between landlord and tenant can happen at any point, as long as both sides consent and the change is recorded in writing to avoid later confusion.
Q What happens if my tenant refuses to pay the increased rent?
If the notice has been served correctly and the effective date has passed, the new rent is legally due. A tenant who disagrees should apply to the First-tier Tribunal before the increase takes effect. If they simply refuse without challenging it, you may end up pursuing rent arrears through the usual routes, but defective service or an unreasonable figure can undermine your position.
Q Do I have to use a specific form for a Section 13 notice?
Yes. A Section 13 notice must be given on the prescribed form published by the government (currently Form 4 in England). Using the wrong form, an out-of-date version, or simply writing a letter can invalidate the notice entirely. Always check gov.uk for the current version before serving, as the prescribed forms are updated from time to time.
Q Can a tenant challenge the amount of the increase?
Yes. If the tenant believes the proposed rent is above market value, they can apply to the First-tier Tribunal (Property Chamber) before the new rent takes effect. The tribunal will assess what a similar property would let for on the open market and can set a rent that is higher, lower, or the same as the landlord proposed.
Q Does a rent increase notice apply during a fixed term?
Generally no. During a fixed-term tenancy, the rent stays as agreed unless the contract contains a rent review clause or both parties agree to a variation in writing. Section 13 notices only apply to statutory or contractual periodic tenancies. Once the fixed term ends and the tenancy rolls over, the statutory route becomes available.
Q What notice period do I need to give?
For weekly or monthly tenancies, at least one month's notice is required. For quarterly or less frequent rent payments, the notice must match the payment interval. For yearly tenancies, six months' notice is required. The notice must give a clear start date for the new rent, aligned with the beginning of a rental period.
Q Can I increase rent to reflect higher mortgage costs?
You can propose any figure you think is justified, but the test is market rent, not your costs. If the tenant refers the matter to the tribunal, they will look at what comparable properties let for locally, not at your mortgage payments, insurance, or maintenance bills. Framing the increase around market evidence gives you a much stronger position.
