Challenging a rent increase: your rights explained
Social rents are regulated and capped. Your landlord can raise your rent at most once a year, by a limited amount. Here is how the rules work and what to do if an increase looks too high.
Get help with my complaintYour rights around challenging a rent increase
Unlike private renting, social housing rents in England are regulated by the Rent Standard set by the Regulator of Social Housing. Under the rent settlement that began on 1 April 2026, your landlord can increase your rent at most once a year, by up to CPI+1% (for 2026–27 that cap is 4.8%).
This is different from the private rented sector, where rent rises follow a "Section 13" notice and can be challenged at the First-tier Tribunal. That route does not apply to social tenants. Your protection comes from the Rent Standard cap and the terms of your tenancy agreement.
If a proposed increase looks higher than the cap, was not properly notified, or does not match your tenancy’s rent-review clause, you can challenge it through your landlord’s complaints process and, if needed, the Housing Ombudsman.
Key facts
Social rent rises are capped
For social rent and affordable rent homes, your landlord can generally increase your rent by no more than CPI+1% per year under the Rent Standard 2026. For 2026–27 that works out at 4.8%, based on the September Consumer Prices Index figure.
At most once a year, with proper notice
Your rent can be increased at most once in any year, and your landlord must give you proper written notice in line with your tenancy agreement before the new rent starts.
The tribunal route is for private tenants, not you
The First-tier Tribunal "market rent" challenge introduced by the Renters’ Rights Act 2025 applies to private tenants, not social tenants. Your rent is set by the regulated formula, not the open market, so a different, simpler protection applies to you.
Some below-formula homes may rise a little more
If your rent is currently below the "formula rent" for your home, your landlord may add a small extra "convergence" increase (up to £1 a week from April 2027 and £2 a week from April 2028) on top of the CPI+1% rise, until the formula rent is reached.
What to do step by step
Keep a written record at every stage. Dates and written communications are your most important evidence.
Check the increase against the cap
Work out whether the rise is more than CPI+1% (4.8% for 2026–27, plus any small convergence amount). If it is higher, ask your landlord in writing to explain how it was calculated.
Check your notice and tenancy agreement
Confirm you were given correct written notice and that the increase follows the rent-review clause in your tenancy agreement. Keep the notice you were sent.
Ask your landlord to justify it in writing
Email your landlord asking them to set out the percentage increase, the date it takes effect, and the rule it is based on. A correctly-calculated increase will be easy for them to explain.
Make a formal complaint if it is wrong
If the increase is above the cap, was not properly notified, or cannot be justified, make a formal Stage 1 complaint. Use TenantSafe to generate a correctly-referenced letter.
Escalate to the Housing Ombudsman
If your complaint is not resolved, escalate to the Housing Ombudsman, which is free. A landlord that systematically breaches the Rent Standard can also be reported to the Regulator of Social Housing.

How much can my social landlord increase my rent?+
Generally by no more than CPI+1% a year under the Rent Standard 2026, which is 4.8% for 2026–27. Some homes whose rent is below the formula rent may see a small additional convergence increase of up to £1–£2 a week.
How often can my rent go up?+
At most once a year, and only after your landlord gives you proper written notice in line with your tenancy agreement.
Can I challenge my rent increase at a tribunal like private renters?+
No. The First-tier Tribunal market-rent challenge is for private tenants. As a social tenant your protection is the regulated CPI+1% cap. If an increase breaks the rules, you challenge it through your landlord’s complaints process and the Housing Ombudsman.
What does CPI+1% mean?+
CPI is the Consumer Prices Index, a measure of inflation. CPI+1% means your rent can rise by the inflation rate plus one percentage point. For 2026–27 that cap is 4.8%.
My rent increase looks too high. What should I do?+
Ask your landlord in writing to explain how it was calculated and check it against the CPI+1% cap and your tenancy agreement. If it is above the cap or unexplained, raise a formal complaint and escalate to the Housing Ombudsman if needed.
