Rent Negotiation Helper
Analyse your landlord's proposed rent increase against inflation and market benchmarks — then get an AI-written negotiation letter tailored to your situation.
Your rights when your landlord proposes a rent increase
In England and Wales, landlords cannot simply raise your rent whenever they like. On a periodic (rolling) tenancy, they must serve a Section 13 notice with at least one month's notice for monthly tenancies, or six months for yearly ones. On a fixed-term tenancy, your landlord can only increase rent if the agreement contains a specific rent review clause — otherwise the agreed rent applies until the fixed term ends.
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. On a periodic tenancy, your landlord must follow the Section 13 procedure and give proper notice (at least 1 month for monthly tenancies). On a fixed-term tenancy, rent can only increase if there is a rent review clause in your agreement. If your landlord tries to increase rent without following the correct procedure, you are not legally obliged to pay the higher amount.
- 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 by Claude Haiku 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?
- If your landlord serves a valid Section 13 notice and you disagree with the proposed increase, you can apply to a First-tier Tribunal (Property Chamber) within 6 weeks of receiving the notice. The tribunal will determine a fair market rent. 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.
