Student guarantors and tenancy sign-up explained

Most Cardiff landlords and letting agents require a guarantor when renting to students, or to anyone whose income does not independently meet the standard reference threshold. The guarantor contracts to cover unpaid rent or damages if the contract-holder cannot pay, and that liability can run for the life of the occupation contract. Asking someone to act as guarantor is a significant request, and both parties benefit from understanding what the commitment actually involves before anything is signed.

Wales has its own legal framework for private rented housing, and it matters here. Under the Renting Homes (Wales) Act 2016, student lets in Cardiff are governed by occupation contracts and the renter is a contract-holder, not a tenant. The guarantor agreement sits alongside this contract, governed by its own stated terms. This guide covers who qualifies as a guarantor for a Cardiff student let, what landlords typically require at sign-up, the documents both parties need to gather, and what to do if a preferred guarantor falls short of the standard requirements. An interactive income estimator further down lets you check whether a proposed guarantor's income is likely to meet typical Cardiff thresholds.

What a guarantor contracts to do

A guarantor is a third party who agrees to meet the contract-holder's financial obligations if the contract-holder fails to do so. In most cases this means covering overdue rent, but depending on how the guarantor clause is drafted it can also include costs arising from damage beyond fair wear and tear at the end of the contract. Where several people share a property, the liability may be joint and several, meaning the guarantor could face a demand for the full sum owed across the property rather than just one person's share. Reading both the occupation contract and the guarantor agreement before signing is essential. Both parties should keep copies of everything they sign, alongside any correspondence with the landlord or agent throughout the contract period.

Who can act as a guarantor for a Cardiff student let

There is no statutory list of who can act as a guarantor in Wales. Cardiff landlords and agents set their own criteria, which typically include UK residency, an annual gross income at least 30 times the monthly rent (with some agents requiring 32x or 36x, so the exact multiple varies), a clean credit history, and sometimes homeownership. Parents or close relatives are the most common choice for student lets, but friends and colleagues can also act in this role provided they meet the income and credit requirements.

Where a parent or relative lives outside the UK, some Cardiff landlords accept an international guarantor alongside a larger deposit or suggest a specialist commercial guarantor service. Cardiff and Cardiff Metropolitan Universities both have accommodation advice teams, and it is worth checking with them before assuming the problem cannot be resolved: universities sometimes operate guarantee or bond schemes, or can refer students to approved providers.

One point to be clear about: Right to Rent checks are an English requirement and do not apply in Wales. A landlord or agent requesting Right to Rent documents in Cardiff has no legal basis for doing so, for the contract-holder or the guarantor.

The sign-up process for Cardiff student lets

Referencing for a Cardiff student let typically begins several weeks before the planned move-in date. The letting agent will reference the student on their expected income, student loan entitlement and parental contribution. Because students rarely earn enough in employment to meet the standard income threshold independently, a guarantor reference is run in parallel. This covers the guarantor's income, credit history and, in some cases, whether they own their home.

Once referencing is complete, the occupation contract is issued to the student and the guarantor agreement is prepared separately. Both documents should be read in full before signing. Under the Renting Homes (Wales) Act 2016, the landlord must give the student a written statement of the occupation contract within 14 days of their occupation start date. The guarantor agreement is a separate contract and is not subject to that same statutory deadline, but it is equally binding the moment it is signed, so the guarantor should treat it with equal care. For more on what the occupation contract should contain and how to read it, see our article on occupation contracts in Wales.

Permitted payments and the deposit

Under the Renting Homes (Fees etc.) (Wales) Act 2019, the only payment permitted before signing is a holding deposit of no more than the equivalent of one week's rent, which must be refunded or credited to the first month's rent unless the applicant withdraws or provides false information. At signing, the landlord may take the first month's rent and a security deposit. Administration fees, referencing fees, check-in charges and credit-check fees are not permitted payments in Wales and can be reported to Cardiff Council. A guarantor should not be asked to pay a separate fee simply for agreeing to provide the guarantee.

If your proposed guarantor does not qualify

If the proposed guarantor does not meet the income or credit criteria, several options are worth exploring. Two people can sometimes act as joint guarantors, with their incomes combined for assessment, which can resolve a shortfall where neither individual reaches the threshold alone. Specialist commercial guarantor services are widely used in the student sector and step in for a fee, making them especially practical where a parent lives abroad. Cardiff and Cardiff Metropolitan Universities' accommodation teams can advise on approved schemes or direct students to suitable providers. Some landlords will also consider a larger upfront deposit or several months' rent paid in advance as an alternative to a personal guarantor, though this is at the landlord's discretion and is not a legal right.

Verifying your landlord with Rent Smart Wales

Before signing anything, confirm that the landlord or their managing agent is registered with Rent Smart Wales. Registration is mandatory in Wales under the Housing (Wales) Act 2014, and an unregistered landlord loses access to the section 173 no-fault possession route until the position is corrected. Verification is free on the Rent Smart Wales website and takes only a few minutes. Our guide to HMO licensing in Wales covers how Cardiff's licensing system works alongside the Rent Smart Wales registration requirement.
