Introduction – What is a Guarantor

A guarantor is someone who promises to be legally liable for your rent and other rental responsibilities. They may also be liable for the rent and legal duties of any co-tenants with whom you live. So, if you or any of your co-tenants do damage to the property or fail to pay your rent, your guarantor may be obligated to pay what you owe the property owner.

What does a Guarantor do?

It's possible that a guarantor may be required when you make a reservation for accommodation in the UK. Offering a guarantee is standard procedure and offers security with assurance that the rent will be paid in whole and on time.

In exchange for signing your guarantor document, a guarantor promises to reimburse any unpaid rent and related rent collection expenses for the renter they are securing. Given that it is a legal document, you should not sign it impulsively.

Requirements for the UK Guarantor

Anybody recognized, qualified by the property owner who owns the property or the agent who manages the property on behalf of the owner, can generally be a guarantor. There are no strict guidelines in this case because different landlords and organisations will have different standards for what they consider suitable.

  • The guarantor must be UK based
  • Must be over 18 years old
  • Guarantor must be able to fulfil their requirements.

This is because they require a guarantor who has the financial resources to cover what you owe if you are incapable or are unwilling to pay for any reason.

You cannot serve as a guarantor for yourself, and you should never list someone as a guarantor in any form without first informing them.


There are a few measures that should be taken before signing a guaranteed agreement if you believe that hiring a guarantor or obtaining a guarantor loan is the best approach to proceed with

renting to prospective renters.

Guarantors must do credit checks and get references in the same way as tenants do. They must also show that they have enough income to fulfil their monthly rent and any other obligations if necessary.

Any modifications to the tenancy agreement, such as a tenancy renewal, will require the consent of the guarantor, as making changes without the guarantor's consent will nullify their responsibility. Guarantors should be provided with adequate time and information to consider any proposed adjustments.
