What is a Guarantor?

A guarantor is a third party (usually a parent, relative, or friend) who signs a legal agreement promising to:

Unpaid rent

Tenant still owes money? Prepare the claim file

If the arrears keep growing, turn the problem into a clearer debt record and claim narrative before the evidence gets harder to untangle.

  • Set out what is owed clearly before the numbers get harder to untangle.
  • Build the claim in plain English.
  • Get the court paperwork ready for the next step.

  • Pay the rent if the tenant doesn't
  • Cover damage costs the tenant is liable for
  • Meet any other financial obligations under the tenancy

The guarantor becomes jointly and severally liable with the tenant. This means you can pursue either the tenant or the guarantor (or both) for unpaid amounts.

When to Require a Guarantor

Consider requiring a guarantor when the tenant:

Financial Risk Indicators

  • • First-time renter with no history
  • • Student or young professional
  • • Low or irregular income
  • • Failed credit checks
  • • Self-employed with variable earnings

Situational Factors

  • • New to the country
  • • Recently changed jobs
  • • Rent is high relative to income
  • • Previous CCJs (but otherwise acceptable)
  • • Benefits recipient

A guarantor doesn't make a bad tenant good—but it does give you someone to claim from if things go wrong.

The Guarantor Agreement

The guarantee must be properly documented to be enforceable. Essential elements include:

  • Guarantor's full name and address
  • Clear statement of what they're guaranteeing
  • Reference to the specific tenancy agreement
  • Statement that the guarantee survives tenancy variations
  • Guarantor's signature (witnessed is better)

Warning: A guarantee that doesn't properly identify the tenancy or clearly state the guarantor's obligations may be unenforceable. Always use a properly drafted guarantee agreement.

Claiming from a Guarantor

If your tenant doesn't pay, you can pursue the guarantor through the same process as claiming from a tenant:

  1. Send a Letter Before Action to the guarantor
  2. Give them 30 days to pay
  3. If no payment, issue a court claim naming the guarantor as defendant
  4. Obtain CCJ against the guarantor
  5. Enforce as needed

You can claim from the guarantor at the same time as the tenant, or wait until you've exhausted attempts to recover from the tenant first. Tactically, claiming from both simultaneously often produces faster results.

Common Issues with Guarantor Claims

"The tenancy was varied without my consent"

Guarantors sometimes argue they're released because rent increased or the tenancy was extended. A well-drafted guarantee covers this by stating it survives variations.

"I didn't understand what I was signing"

Courts expect guarantors to read what they sign. Unless there was actual fraud or misrepresentation, this defence rarely succeeds.

"The guarantee has expired"

Some guarantees are limited to an initial fixed term. Check your guarantee wording— ideally, it should cover "the tenancy and any statutory periodic continuation."

FAQs for landlords

Can I require a UK-based guarantor only?

Yes. It's reasonable to require a UK guarantor because enforcing against overseas guarantors is extremely difficult and expensive.

Should I credit check guarantors?

Absolutely. A guarantor with poor credit or no assets doesn't provide meaningful security. Check they can actually pay if needed.

Can the guarantor end their guarantee?

Generally no—not unilaterally. The guarantee lasts for the period specified (or the whole tenancy if not specified). They can't simply withdraw.
