Key Takeaways:
A rent guarantor is often one of the most important parts of the renting process, but it can also be one of the most confusing. Whether you’re renting for the first time, moving to the UK, changing jobs or applying for a property as a student, being asked for a guarantor can create uncertainty, delays and concerns about whether you’ll be able to secure the home you want.
The good news is that it does not need to be complicated. Understanding how rent guarantors work, why landlords ask for them and what alternatives exist can make the process far easier to navigate.
In this guide, we explain what a rent guarantor is, how they work, who typically needs one and what you can do if you cannot get a rent guarantor in the UK.
A rent guarantor is someone who agrees to take financial responsibility for your tenancy if you are unable to meet your obligations. In most cases, this means covering unpaid rent, but it can also include costs such as property damage or breaches of the tenancy terms.
This responsibility is usually set out in a guarantor agreement, a legal document signed alongside your tenancy that explains exactly what the guarantor may be responsible for and for how long.
Landlords and letting agents ask for guarantors to reduce financial risk. If a tenant falls behind on rent, causes damage or breaches the terms of a tenancy agreement, a guarantor provides an additional layer of security.
You are more likely to be asked for a guarantor if you are renting for the first time, moving to the UK, studying, self-employed, have a lower income, or do not meet affordability and referencing requirements.
Not necessarily. Many tenants rent without a guarantor, particularly if they meet a landlord’s affordability and referencing requirements. If you have a stable income, a strong credit history and can comfortably demonstrate that you can afford the rent, you may not be asked to provide one.
Requirements vary between landlords and letting agents, but you are more likely to need a guarantor if you are a student, renting for the first time, new to the UK, self-employed, receiving benefits or applying for a property where affordability requirements may be harder to meet.
In many cases, landlords will also expect guarantors to meet certain requirements in the UK. This often includes being UK-based, passing credit checks and demonstrating a sufficient income level. Some landlords may also require guarantors to be homeowners, although this is not always the case.
If a landlord or letting agent asks for a guarantor, you will usually nominate someone who has agreed to support your application. In most cases this is a parent, family member or close friend. Landlords will usually expect them to meet specific criteria such as being UK-based, passing affordability checks and demonstrating a sufficient level of income.
Once nominated, the guarantor will be contacted as part of the referencing process. They may be asked to provide identification, proof of income and supporting documents before completing credit and affordability checks. If approved, they will then sign a guarantor agreement outlining exactly what they are responsible for during the tenancy.
Not everyone has access to a suitable rent guarantor. If you are moving to the UK, studying as an international student, renting for the first time or relocating away from family, finding a UK-based guarantor can be difficult. Equally, acting as a guarantor is a significant financial responsibility, and friends or family members may not always feel comfortable taking that on.
This challenge has become increasingly important following changes introduced under the Renters’ Rights Act. Before May 2026, some tenants who could not provide a guarantor were able to strengthen their application by offering several months of rent upfront. With landlords and agents now more limited in relying on large upfront rent payments in many situations, alternative routes have become more important for some renters.
Fortunately, this does not automatically prevent you from renting a property. Professional guarantor services offer an alternative route, acting as a third party that guarantees your tenancy agreement on your behalf.
Services such as RentGuarantor support students, working professionals, self-employed applicants and international renters who may not have access to a traditional guarantor. In return for a fee, they provide landlords and letting agents with the same additional security that a personal guarantor would typically offer.
If you need a rent guarantor, there are generally two routes available. You can ask a friend or family member to act as your guarantor, or you can use a professional guarantor service.
Professional guarantor services have become increasingly common among international renters, students and professionals relocating to the UK who may not have access to a suitable UK-based guarantor.
Both options can help you secure a rental property. The right choice depends on your circumstances and whether you have access to a suitable guarantor.
Professional rent guarantor services are designed to provide landlords with the same reassurance as a traditional guarantor, but through a specialist company instead of a friend or family member. While the exact process varies by provider, it usually follows a few simple steps:
Professional guarantor services are increasingly used by students, international renters, self-employed applicants and professionals relocating to the UK, helping tenants secure homes even when a traditional UK-based guarantor is unavailable.
Being asked for a rent guarantor can feel like another obstacle in an already complicated rental process, particularly if you are moving to a new city, relocating to the UK or renting for the first time. In reality, a guarantor is simply one part of the referencing process designed to provide landlords with additional reassurance.
Whether you use a friend or family member, qualify without a guarantor, or choose a professional guarantor service, there are now more options available than many renters realise. Understanding how the process works and preparing early can help reduce delays and make securing your next home much more straightforward.
If you are unsure whether you need a rent guarantor or want guidance on your options, speaking with your letting agent early in the process can help avoid surprises later on.
In many cases, students are asked to provide a guarantor, particularly if they are renting privately or studying in the UK from overseas. With changes introduced under the Renters’ Rights Act reducing reliance on large upfront rent payments in some situations, guarantors and professional guarantor services have become increasingly important for many student renters.
