How interest-only mortgage payments are worked out
The formula, monthly payments for common loan sizes, the comparison with repayment, and the savings needed to clear the loan.
In England the deposit is capped at five weeks' rent for most tenancies. Here is what that means at your rent, and the other limits.
In England the law limits how much a landlord or letting agent can ask you to pay before you move in. There is a cap on the tenancy deposit, a cap on the holding deposit and, since 1 May 2026, a limit on rent paid in advance. Here is what each one allows.
A tenancy deposit can be no more than five weeks' rent where the yearly rent is under £50,000, or six weeks' rent where it is £50,000 or more. A holding deposit can be no more than one week's rent.
The Tenant Fees Act works out a week's rent as the yearly rent divided by 52. For a monthly rent, multiply by 12 first, then divide by 52.
| Rent a month | A week's rent | Most the deposit can be | Most the holding deposit can be |
|---|---|---|---|
| £900 | £207.69 | £1,038.46 | £207.69 |
| £1,200 | £276.92 | £1,384.62 | £276.92 |
| £1,500 | £346.15 | £1,730.77 | £346.15 |
| £2,000 | £461.54 | £2,307.69 | £461.54 |
| £4,500 | £1,038.46 | £6,230.77, six weeks | £1,038.46 |
The six-week cap starts at £4,167 a month, which is £50,000 a year. Tenancies with rent over £100,000 a year are outside the Tenant Fees Act altogether.
A holding deposit reserves the property while checks are done. The landlord has 15 days to agree the tenancy, unless you agree a different date in writing. If the tenancy goes ahead, the holding deposit is usually put towards the first rent or the deposit. If it does not, it must be returned within 7 days, unless you gave false information, pulled out, did not respond to reasonable requests or failed a Right to Rent check. If the landlord keeps it, they must tell you why in writing within 7 days.
The Renters' Rights Act 2025 changed the rules on rent paid upfront for tenancies from 1 May 2026. A landlord cannot ask for or accept rent before you have signed the tenancy agreement. After you sign, they can ask for no more than one month's rent before the tenancy starts. The deposit caps themselves did not change.
Anything over the caps is a banned payment and has to be refunded. You can raise it with the landlord or agent, contact your local council, which enforces the rules through Trading Standards, or apply to the First-tier Tribunal to get the money back.
These rules are for England. Scotland and Wales have their own rules on deposits and fees.
