Your rights when your landlord proposes a rent increase
Landlords cannot simply raise your rent whenever they like, and the rules differ across the UK. In England: Since 1 May 2026 (Renters' Rights Act 2025), private tenancies in England are periodic, including ones that started on a fixed term. A rent review clause in your agreement no longer lets the rent go up. Your landlord must serve a section 13 notice (Form 4A) giving you at least two months' notice of the new rent, and can raise it at most once every 52 weeks. You can challenge the increase at the First-tier Tribunal (Property Chamber) before it takes effect. The tribunal decides the open-market rent, and it cannot set a rent higher than your landlord asked for.
In Wales (Renting Homes (Wales) Act 2016), your landlord must give you at least two months' written notice of a rent increase on a periodic standard contract, and can raise it at most once every 12 months. In Scotland (private residential tenancy), your landlord must give you at least three months' notice of a rent increase on the prescribed form, at most once every 12 months. You can refer it to a rent officer. Rent control rules are changing, so check mygov.scot for what applies now. In Northern Ireland, private rents can go up at most once every 12 months, and your landlord must give you written notice. Check nidirect.gov.uk for the notice your tenancy needs.
Even where a rent increase is legally valid, that does not mean you must accept it. The UK rental market has seen significant rent inflation in recent years, but many landlords will negotiate — particularly with reliable, long-standing tenants. A well-reasoned letter citing inflation benchmarks and comparable market rents often achieves a reduction.
What to include in a negotiation letter
The most effective negotiation letters are calm, factual, and specific. Reference the Consumer Price Index (CPI) and typical rent increases in your area. Highlight your track record as a tenant — consistent on-time payments, care of the property, and length of tenancy. If comparable properties nearby are available for less, mention them. Propose a specific counter-offer rather than simply objecting to the increase.
This tool generates both a template letter and an AI-personalised letter based on your specific circumstances. The AI letter incorporates your reasons, context, and the financial analysis to produce something more tailored than a generic template.
Frequently asked questions
Can my landlord increase my rent whenever they want?
No. Since 1 May 2026 (Renters' Rights Act 2025), private tenancies in England are periodic, including ones that started on a fixed term. A rent review clause in your agreement no longer lets the rent go up. Your landlord must serve a section 13 notice (Form 4A) giving you at least two months' notice of the new rent, and can raise it at most once every 52 weeks. If your landlord tries to increase rent without following the correct procedure, you are not legally obliged to pay the higher amount. Wales, Scotland and Northern Ireland have their own rules — pick your nation in the tool above.
How is the 'fair' assessment calculated?
The tool compares the proposed increase percentage against the current CPI inflation rate and the UK average rent increase (sourced from the HomeLet Rental Index). An increase at or below CPI + 1% is classified as 'reasonable'. Between CPI + 1% and the UK average + 2% is 'above average'. Higher than that is 'excessive'.
Is the AI-generated letter actually personalised?
Yes — the AI letter is generated using the specific figures you enter (current rent, proposed rent, tenancy length) combined with the reason and context you provide. It produces a different letter for each situation, unlike the static template which uses placeholder text.
What if my landlord refuses to negotiate?
In England, if your landlord serves a valid section 13 notice and you disagree with the proposed increase, you can apply to the First-tier Tribunal (Property Chamber) before the new rent is due to start. The tribunal decides the open-market rent and cannot set it higher than your landlord proposed. Citizens Advice and Shelter have guidance on this process.
Is this legal advice?
No. This tool provides general guidance based on English and Welsh housing law. It is not legal advice. For specific legal questions or if you are facing eviction, consult a solicitor or your local Citizens Advice bureau.
