I’m a huge advocate of tenant guarantors, and I believe every landlord should be too.
I have always considered them a complete no-brainer, so I’m often surprised when I come across landlords willing to sign tenancy agreements without one. Baffling.
But more importantly, I genuinely believe tenant guarantors have become absolutely essential with the introduction of the Renters’ Rights Act, which has seemingly exposed landlords to greater risk, specifically by making it more difficult to evict rogue tenants.
Why wouldn’t you insist on a guarantor? What is the downside?
I think many landlords assume guarantors should only be used for high-risk tenants, but I would argue they provide an additional layer of security that virtually every landlord can benefit from, regardless of the tenant’s perceived risk profile.
So, in this blog post, I am going to set out my best arguments for why I believe landlords should seriously consider requiring tenant guarantors, while also covering many of the key points and frequently asked questions surrounding the topic.
The information in this post applies to tenancies in England.

Quick Overview of Tenant Guarantors
- A tenant guarantor is a third party (usually a family member or friend) who agrees to take financial responsibility for a tenant’s obligations under a tenancy agreement;
- The guarantor’s primary role is to ensure the tenant meets their financial obligations, including paying rent and covering damages or unpaid bills;
- Landlords often prefer (and sometimes require) a tenant guarantor because they provide additional security, particularly where a tenant has a limited rental history or poor credit profile;
- If the tenant fails to meet their obligations, the guarantor can be held liable for the outstanding costs;
- A Tenant Guarantor Agreement is a legally binding contract that sets out the guarantor’s responsibilities and obligations;
- The agreement may specify the circumstances in which the guarantor can be pursued for payment, including rent arrears, property damage, and other financial liabilities.
What Is a Tenant Guarantor?
A “guarantor” is a person that agrees to accept financial liability for a tenant in a rental agreement. The primary purpose of a tenant guarantor is to provide the landlord with additional security in case the tenant fails to meet their obligations. For example, if the tenant falls into arrears the landlord can pursue the guarantor for the money. It can also include covering damages.
Once a guarantor signs an agreement, they become legally bound to honour the agreement.
Who Can Be a Tenant Guarantor?
Essentially, anyone over 18 can be eligible to be a guarantor, but they’re usually a family member or a close friend of the tenant. There are also specialist guarantor companies that provide a service for those that can’t get a guarantor (but that’s less commonly relied upon).
The landlord has the right to refuse any prospective guarantor that is unsuitable to take on the role. Obviously the guarantor needs to be in a financial position whereby they can realistically be pursued for any outstanding monies owed by the landlord, otherwise what’s the point?
To help verify whether a prospective guarantor is suitable, they should be thoroughly referenced like just like tenants.
Being a guarantor is not a task that should be taken lightly – but sadly, it far too often is. It entails taking on a lot of responsibility on behalf of someone else. Honestly, I’ve heard of so many relationships going down the shitter and seemingly becomes unrepairable after guarantors’ have been pursued to cover costs incurred by the person they’ve vouched for, it’s actually quite alarming. The reality is, most people only agree to becoming a guarantor because they don’t actually believe the tenant will default. That often doesn’t end well.
So it is imperative guarantors understands their responsibilities and the risks involved.
What Is a Tenant Guarantor Agreement?
A Tenant Guarantor Agreement (also known as a Guarantor Agreement Contract) is used to create the legal binding agreement with the guarantor. The contract sets out the terms and conditions of the agreement.
The guarantor agreement is NOT a substitute for an Tenancy Agreement, but rather it should be used as a supplement.

Types of Tenant Guarantor Agreements
- Within the tenancy agreement – the terms and conditions of the guarantor are part of the original Tenancy Agreement contract). In this case, the tenant, landlord and guarantor sign the tenancy agreement.
- Deed of guarantee – this is when there is a separate agreement/contract, which sets out the terms and conditions. It’s a separate document from the tenancy agreement.
When and Who Signs the Guarantor Agreement?
The who
In a typical guarantor agreement, it is required for the landlord and guarantor to sign the document.
Some agreements do make an allocation for a witness, but it isn’t necessary. I think it’s good to have one, though.
Two copies of the agreement should be signed, and one should be kept by the landlord and the other by the guarantor.
The when
With the rental agreement: The guarantor agreement is typically signed simultaneously with the tenancy agreement contract. This ensures that all parties involved – the tenant, landlord, and guarantor – are aware of their respective obligations and that the terms are clear from the beginning.
Before Move-In: The guarantor should ideally sign the agreement before the tenant moves into the property. This ensures that the financial responsibility of the guarantor is established from the start of the tenancy.
While it’s not that common, it is possible to include (or even amend) a guarantor in the middle of a tenancy if both tenant and landlord mutually consent. If that’s the case, then obviously signing before the move-in date doesn’t apply.
What Is Included in a Tenant Guarantor Agreement?
While guarantor contracts differ from one another, they all generally contain the same core information, which is as follows:
- Date – the date at which the Guarantor contract was signed
- Guarantor details – the name and contact information of the Guarantor
- Landlord details – the name and contact information of the landlord
- Tenant details – the name of the tenant or tenants for whom the guarantor is providing the guarantee
- Property – the address of the property that is being rented
- Tenancy term – the start and end date of the fixed terms of the tenancy
- Rent – how much rent is being paid
- Guarantee Terms & Conditions – the conditions under which the guarantor’s obligations will be activated, typically after the tenant has failed to meet their obligations, such as not paying rent.
- Signatures – the Guarantor’s signature. It is also recommended to get a signature from a witness.
How to Find and Reference a Tenant Guarantor
Finding a suitable guarantor is arguably as important as finding a suitable tenant. Well, almost. My point is, it’s important.
A guarantor should never compensate for an unsuitable tenant; both tenant and guarantor should be properly referenced, credit checked and ultimately deemed suitable.
You should be able to use most professional tenant referencing services to also reference guarantors.
If you’re looking for suggestions, I’m happy to recommend OpenRent’s credit check service – I’ve used them several times to qualify prospective guarantors, and they’re my go-to. Details below:

Please note, I try my best to keep the information of each service up-to-date, but you should read the T&C's from their website for the most up-to-date and accurate information.
If after referencing the guarantor is found to be unsuitable (i.e. they have poor credit rating), you may want to ask your prospective tenant to find someone else to take the position. Failing that, you may want to find another tenant that is able to find a more suitable guarantor (that’s what I would do anyways).
How Much Should a Tenant Guarantor Earn?
There’s no hard and fast rule, but common sense prevails. They need to earn enough to sustain their own life and potentially your tenants.
A common consensus is that a guarantor should have an income of at least three times the annual rent and that they should earn more than the tenant. So, if the rent is £850 PCM, the guarantor is usually expected to earn at least £30,000 per annum.
Should Landlords Require a Tenant Guarantor?
Guarantors aren’t required to form a legally binding tenancy, so landlords don’t “need” one per se.
Many landlords don’t insist on them, and many manage just fine. However, in my view, that’s like going on holiday without travel insurance.
I personally make it a requirement for all my tenants, least of all because having a guarantor comes at no extra cost [for landlord or tenant] and they provide a useful and robust safety net for landlords.
It used to be the norm to only call upon a tenant guarantor when a landlord feels hesitant about renting to a certain tenant due to concerns about their ability to meet their obligations. For example, where a tenant does not meet the landlord’s standard income or credit requirements. This often includes students, young adults, or individuals with limited rental history. But nowadays, it’s common for landlords to require a guarantor in all cases.
I personally think the old ways was nonsensical – it’s a weird, if you think about it logically, innit? If a tenant is high-risk or raises any concerns (basically, unsuitable for the vacancy), then why are they being considered in the first place? A guarantor shouldn’t be used to compensate or patch holes. As mentioned already, I believe both tenant and guarantor should be verified and suitable for the given tenancy.
First and foremost, all landlords should have tenants that meet the requirements in place, because after all, they’re the ones’ that will be living in the property and expected to pay the bills. A guarantor is a backup plan that no one should want to rely on, so minimising the likelihood of needing one to step in and save the day should be a priority.
Does Every Tenant in a Joint Tenancy Need a Guarantor?
Not necessarily, it depends.
With a married couple, it’s usually easy enough to get one guarantor to accept liability for the pair. However, if a guarantor isn’t willing to do that, I normally require each tenant to get their own guarantor (that’s quite often the case with unmarried or newly established couples).
Some guarantor agreements includes a joint and several liability position by default. This means that if there are multiple guarantors’ or just one guarantor for a tenancy, each guarantor is responsible for their proportionate share of the debt, but they are also collectively responsible for the full amount. So the landlord can choose to pursue any one of the guarantors for the entire debt or seek contributions from multiple guarantors, depending on their preferences.
In other words, a guarantor can be responsible for the arrears of every tenant under a joint tenancy, even if the guarantor has no idea who the other tenants are (this is common in a student setting).
Needless to say, it’s crucial to check the terms of the agreement.
What Happens if a Tenant Falls Into Rent Arrears?
In the event where the tenant falls into arrears and/or needs to repay any other outstanding debts, the liability can fall onto the guarantor. And this is precisely what guarantors were designed and created to do.
If the guarantor fails to cover the costs (and essentially breaches the terms of their guarantor agreement), then the landlord can take legal action against the guarantor.
So, in this case, landlords can pursue either tenant and/or guarantor for any owed money, but it’s usually the case that chasing the guarantor makes more financial sense, as they’re more likely to have the means to pay the debt.
