Rent Increase & Tenancy Renewal Rights (UK)

A rent rise lands hardest when you weren't expecting it. The good news: in England and Wales a landlord cannot simply charge what they like, whenever they like. There are rules on when they can increase rent, how much notice they must give, and your right to challenge an unfair increase. This guide covers the essentials so you can respond calmly and save money.

1. During a fixed-term tenancy

If you are in a fixed-term assured shorthold tenancy (AST), the rent usually cannot be increased until the term ends — unless your contract contains a rent-review clause that sets out how and when rises happen. Even then, the clause must be fair and clearly worded. Without such a clause, any increase during the fixed term requires your written agreement. You are free to say no; the landlord cannot evict you simply for refusing a mid-term rise.

2. The Section 13 notice (periodic tenancies)

Once you are on a periodic tenancy (rolling week-to-week or month-to-month), the landlord can propose a rent increase using a Section 13 notice (Form 4 in England). This is the only lawful route for a unilateral increase. The notice must be in writing, use the correct form, and state the new rent and the date it takes effect. Scotland and Northern Ireland have different regimes (private rented tenancies there use distinct procedures), so check the rules for your nation.

3. How much notice is required

• At least one month for a monthly tenancy (or the length of the rental period, whichever is longer).
• At least six months must have passed since the tenancy began or since the last increase.
• The increase can only take effect at the end of a rental period, not mid-month.

If the notice is late, badly formed, or uses the wrong process, it is invalid — and you can continue paying the old rent.

4. Challenging an excessive increase

You can apply to the First-tier Tribunal (Property Chamber) to set the rent at a lower "market rent" if the proposed amount is significantly above what similar local properties command. The application must usually be made within 28 days of the Section 13 notice. The tribunal compares your home to comparable lettings, so gather evidence (rightmove/zoopla listings nearby). Crucially, challenging the rent does not affect your security of tenure — your landlord cannot evict you for doing so.

5. What happens at renewal

There is no automatic "renewal" of an AST in the same form; when a fixed term ends you typically roll onto a periodic tenancy unless you sign a new fixed term. A landlord who wants you out must serve a Section 21 notice (with all prescribed documents) or, for breach, a Section 8 notice. If you receive a Section 21 after querying rent, take advice — it may be a retaliatory eviction, which can be challenged.

6. Frequently asked questions

Can my landlord raise the rent during a fixed-term tenancy?

Generally no, unless your tenancy agreement has a rent-review clause that allows it, or you both agree in writing. Otherwise the landlord must wait until the fixed term ends and use a Section 13 notice for a periodic tenancy.

How much notice must a landlord give for a rent increase?

For a periodic assured shorthold tenancy, a Section 13 notice must give at least one month (for monthly tenancies) or the period of the tenancy (whichever is longer), and at least six months must have passed since the tenancy began or the last increase.

What if the new rent is unfair or too high?

You can challenge it with the First-tier Tribunal (Property Chamber) within 28 days of the Section 13 notice. The tribunal can set a lower 'market rent' if the proposed amount is excessive.
