Guarantor Services — a neutral comparison of UK rent guarantor providers
If a landlord asks for a guarantor and you do not have a UK-based friend or family member who can sign, you can use a professional guarantor service. There are at least thirteen on the market in England and they are not equivalent. Some are unsuitable for central London rents. Some publish their fees clearly; some do not. Some only work through specific letting-agent platforms. This page is the neutral comparison we publish so you can confirm or override our operational default with an informed decision of your own.
Why we publish this
Two reasons. The first is legal. Under the Tenant Fees Act 2019, a landlord or agent can require a suitable guarantor as a condition of granting the tenancy, but they cannot lawfully require you to take out a particular third-party service, loan, or insurance contract to satisfy that condition. That principle is explicit on GOV.UK. You can use a UK-based personal guarantor, a university guarantor scheme if your institution offers one, or any professional guarantor service of your own choice. We do not require, and cannot lawfully require, you to use any specific provider.
The second is practical. The market is not as transparent as renters need it to be. A handful of providers publish clear fees, cover limits, and refund terms. Several operate on quote-only models. Some only work where the letting agent uses a particular platform. For central London, the £3,000 per calendar month test matters because some products cap the whole tenancy at that amount while others can support much higher rents. The result is that students and overseas tenants — the people most likely to need a professional guarantor under the Renters' Rights Act 2025 — are also the people least equipped to compare like-for-like.
We rent a lot of properties to international students taking private residential tenancies above £3,000 per month, in areas where the choice is not "halls or here" but "private rental or no London course". The Renters' Rights Act 2025 removed the old workaround of paying six or twelve months' rent up front (only one month's rent in advance is now permitted after the first payment cycle). For those tenants, a professional guarantor service is usually the only practical route. Rather than hand them one product, we did the research properly and published it.
Our operational default — and why it is not the only option
We use Goodlord for tenant referencing on most of our managed lettings. Where the rent is at or below £3,000 per calendar month and Goodlord referencing is already running, Goodlord Guarantor is our operational default — and most tenants who take that route end up choosing it. The reason is friction. The application, identity verification, right-to-rent check, referencing, contract execution, first-month rent collection, and guarantor onboarding all sit on a single integrated platform. The tenant does not have to assemble documents in one place, upload them to a guarantor provider in another, wait for two separate decisions, and reconcile two payment flows. For sub-£3k tenancies, especially those involving full-time Higher Education students under the Goodlord income-test exemption, that operational fit is real and material. We have built the worked end-to-end pathway specifically for student lettings — see our Student Lettings page.
We publish this comparison page so that the default is a choice you have confirmed, not one you have been steered into. Three groups of tenants should look harder at the alternatives below. First, anyone whose rent is above £3,000 per calendar month. Goodlord is not eligible at that rent and the question is which of RentGuarantor, Housing Hand, or flatfair is the right substitute. Second, joint tenancies where each tenant's individual share matters more than the headline rent, because some products cover share-only and some cover the whole tenancy on different terms. Third, tenants who actively prefer instalment payments, a different fee structure, or a different cover scope (some products cover damages and dilapidations as well as rent; Goodlord's product covers rent only). Outside those three groups, Goodlord is usually the practical answer — and we will say so when you ask. Inside them, the rest of this page is the working comparison.
What a professional guarantor actually does
A guarantor is a person or company that signs the tenancy agreement alongside you and agrees to pay the rent if you do not. A professional guarantor service substitutes a corporate guarantor for a personal one. Five points are worth understanding before you compare providers, because they change the cost-benefit picture substantially.
First, a guarantor service does not make the rent someone else's problem. If the provider pays the landlord on your behalf, you usually still owe the provider. The provider's contract with you sets the repayment terms. Read those terms before paying any fee.
Second, the landlord or letting agent has to accept the provider. Not all do. Smaller landlords, particularly those who manage their own properties, may not have heard of any of the corporate providers and may refuse on that ground alone. Never pay a non-refundable fee until the landlord or letting agent has confirmed in writing that they will accept the named provider.
Third, joint-tenancy wording matters more than any other clause. In a joint tenancy, each tenant is usually responsible for the whole rent, not just their share, unless the agreement says otherwise. A guarantor product that only covers your share leaves you exposed if a flatmate stops paying. Some products cover share only; some cover the whole tenancy; some can do either depending on how the application is structured. Get this in writing.
Fourth, most products cover rent only. They do not cover utilities, council tax, cleaning, or dilapidations. A few are broader — Housing Hand under its University of London partner description includes damages and professional eviction costs — but you should always verify the exact wording of the guarantee, not the marketing copy.
Fifth, agent commissions exist. Several of the corporate providers pay referral commissions to letting agents, typically between 10% and 15% of the guarantor fee. That is a normal feature of the market and is not by itself a problem. It does mean you should understand whether an agent recommending a particular provider is doing so on neutral grounds or on commercial ones. We are telling you about ours: we use Goodlord for referencing and have built one pathway with their Guarantor product, and we do not require you to use it.
The central London cost reality
The provider you should choose depends partly on your rent. The ranking that works for a £1,500-per-month room in Zone 3 is not the ranking that works for a £4,500-per-month two-bed in Marylebone. The most important single number is whether the provider can cover your monthly rent at all.
| Provider | Maximum monthly rent | Suitable for £3,000 pcm? |
|---|---|---|
| RentGuarantor.com | £10,000 (with £120,000 arrears cap) | Yes |
| flatfair Tenant Guarantor | No monthly cap stated; £100,000 total unpaid-rent cap | Yes |
| Housing Hand / UK Guarantor | No public hard cap | Likely — confirm in writing |
| Goodlord Guarantor | £3,000 per tenancy (not per tenant) | Yes, exactly — not above |
| RentBuddy.co.uk | £5,000 | Yes |
| Homeppl Guarantid | Stated as "any rent amount" (B2B page) | Likely — confirm in writing |
| Tenancy Guarantor | No public cap | Possibly — quote required |
| Tenanta | No public cap | Possibly — quote required |
| Study Stay UK | Advertises arrangements up to £8,500 | Yes (on cap; pricing not public) |
| Rentmigo | No public cap | Unknown |
The Goodlord limit is worth understanding because it is the most common trap for central London student tenancies. The £3,000 cap applies per tenancy, not per tenant. A four-bedroom student flat at £4,800 per month does not become eligible because it is split four ways into £1,200 per tenant. The whole tenancy must be under £3,000 per month. That rules Goodlord Guarantor out for most central London shared student lettings as a matter of pure arithmetic.
How the ten ranked providers compare
The ranking below is based on student suitability, pricing transparency, central London rent suitability, landlord and agent acceptance, clarity of coverage, refund and cancellation terms, trust signals, and compatibility with post-Renters' Rights Act periodic tenancies. It is not a recommendation. The five "most practical first checks" are the providers with the clearest published terms.
Most practical first checks
1. RentGuarantor.com. Highly transparent. Publishes both a price guide and a high rent-cover position: protection up to £10,000 monthly rent with a £120,000 arrears cap, plus £10,000 for legal expenses related to eviction proceedings for non-payment. Guide price is three to four weeks' rent as a one-off annual fee, payable at the start of the tenancy for up to three years on renewal. Instalment options may be available through PayPal or Payl8r subject to acceptance. For shared properties, if only one tenant uses the service the guarantee covers only that tenant's portion; where two or more tenants apply jointly, the fee is split equally. Rent only — does not cover utilities, council tax, or damages.
2. Housing Hand / UK Guarantor. The most student-focused provider in the market, widely referenced by universities and student accommodation platforms. The University of London partner page gives a clean fee: 5% of the annual tenancy upfront or 5.5% in twelve monthly instalments, subject to a £295 minimum. The partner description says the cover includes rent, damages, dilapidations, and professional eviction costs — broader than most of the rent-only products — but you should verify the exact guarantee wording, because Housing Hand also markets a narrower student product from £42 in eight instalments. Guarantor length is typically six to twelve months, with renewal needed after twelve months. A co-signer (usually family) is normally required and is not subject to a credit check.
3. flatfair Tenant Guarantor. Strong on published terms. The fee is a one-off four to six weeks' rent, depending on referencing outcome and risk tier. It protects landlords for up to twelve months' unpaid rent, maximum £100,000, plus up to £10,000 in eviction legal costs. Cover is the tenant's share of rent only, for the full tenancy term up to three years including renewals. It does not cover utilities, council tax, damage, or cleaning. The main limitation is distribution. flatfair is typically offered through the participating letting agent rather than self-served by the tenant, so it depends on whether your landlord or agent has the integration.
4. Goodlord Guarantor. A strong standalone product irrespective of any agent relationship. The fee structure is the simplest in the market: one upfront payment equivalent to one month's rent, no instalments to administer, no admin fee, and one payment covers all tenants on the agreement for the whole tenancy up to three years. Cover is explicitly positioned around the Renters' Rights Act environment. The full income-test exemption for full-time Higher Education students is a meaningful advantage for international students who cannot evidence UK earnings. Refund terms are clear: before move-in, a landlord can reject the service and the tenant receives a full refund; after the tenancy has started, no refunds are provided. The eligibility cap is no more than £3,000 monthly rent per tenancy, applied per tenancy not per tenant: this is the central London limitation, and the reason a £4,800-per-month four-bed student flat is not eligible regardless of how the rent splits per tenant. Two of these features — fee simplicity and the student income-test exemption — would put Goodlord Guarantor in the top five on the comparison even for a tenant whose letting agent has no Goodlord relationship at all. Where the letting agent does already use Goodlord for referencing (we do), an additional practical advantage exists that the standalone providers cannot match: platform integration. The referencing, identity verification, guarantor application, contract execution, and payment all stay on one platform, which removes friction and reduces the document-handling burden on the tenant. That integration is what makes Goodlord our operational default for sub-£3k student tenancies. See our Student Lettings page for the worked pathway.
5. RentBuddy.co.uk. Supported by FCC Paragon's referencing process. Available for residential tenants in England including students and international tenants, with right immigration documents, share code, or settled or pre-settled status. Each joint tenant must apply and be approved individually; only approved tenants are covered. Cover lasts up to 36 months for rents up to £5,000 per month. Fees are based on one month's rent share, subject to a £250 minimum, plus VAT, with no instalments. There is a 14-day cooling-off period before the tenancy starts, but once the tenancy begins fees are non-refundable.
Worth checking where applicable
6. Homeppl Guarantid. Aimed at students, internationals, self-employed renters, and people without UK credit history. More partner-led than self-serve. Universities can refer undergraduate or postgraduate students, UK or abroad. Pricing on crawled Guarantid pages indicates a charge of 5.8% of total annual rent, working out at approximately three weeks' rent, with up to two instalments allowed, but you should treat this as indicative and ask Homeppl for a written quote. Covers missed rental payments but not property damage. A friend or family member as co-signer is usually required.
7. Tenancy Guarantor. Simple fee model: a £14.99 non-refundable administration fee if you proceed, then a full service fee equivalent to one month's rent once the landlord or agent confirms acceptance. Supports students and employed tenants. Tenancy Guarantor Ltd was incorporated on 5 March 2025; Companies House also showed an overdue confirmation statement at the time of checking. That does not automatically mean the service is unsuitable, but it is worth checking the current company status, terms, insurance backing, and landlord acceptance before relying on a newer company.
8. Tenanta. Newer contractual guarantor service. Covers rent only — not utilities, council tax, or damages — and a formal claim can only be made once arrears reach 61 days or more. The public calculator gives an illustrative example: for monthly rent of £1,800, a 12-month rental guarantee gives a total guarantee fee of £2,398 with monthly instalments of £200, or £2,158 upfront. The page explicitly says the calculator is illustrative only. Annual payment is one fixed fee normally covering twelve months; renewal is needed where the tenancy is renewed. An initial processing fee may be non-refundable.
9. Study Stay UK. Specifically positioned for international students from China and Hong Kong; advertises rental arrangements up to £8,500 per month with decisions in under 24 hours and no UK credit history requirement. Pricing is not publicly disclosed. Treat as quote-required.
10. Rentmigo. Acts as a UK rent guarantor for international students who can afford rent but do not have a UK-based guarantor. Assessment focuses on affordability, overseas income, scholarship funding, or family support rather than UK credit history. Supports private rentals across the UK, including rooms in shared houses, studios, and full apartments. No public pricing or cap.
Watchlist providers — not ranked
The Student Guarantor. Describes itself as a UK rent guarantor for international students. University of London Housing Services identifies it as another guarantor service offering a UK-based rental guarantor solely for international students. The Student Guarantor Limited was incorporated on 11 June 2025. Public pricing, caps, and refund terms were not verifiable during checking. Worth watching as the company matures.
Bontly Rent. Acts as a corporate guarantor; gives fast approval for students and expats; charges a £25 processing fee to start the official application; aims to review most applications within 24 hours. Not ranked because the main fee formula and maximum rent cap are not publicly disclosed.
TheGuarantor.co.uk. Not ranked because public wording found during checking appeared inconsistent: some pages refer to rent support or corporate guarantee wording, while another FAQ result said it does not provide a financial guarantee or insurance product. Clarify with the provider directly before relying on it.
University guarantor schemes — usually cheaper, often capped low
If you are a full-time student at a London university, check whether your institution runs its own guarantor scheme before paying any corporate provider. Two well-known examples:
UCL Rent Guarantor Scheme. Open to eligible full-time UCL students, including overseas and EU students; updated for the Renters' Rights Act; £50 application fee. Caps rent at £350 per week, equivalent to £1,517 per calendar month, per UCL student.
LSE Rent Guarantor Scheme. Helps eligible continuing full-time LSE students; £50 administration fee. Caps accommodation at £1,000 per month per person.
The price is unbeatable where you qualify. The rent caps are usually the constraint. Neither scheme will support a £3,000-per-month central London studio or a higher-end shared flat. If you are taking a property close to those caps, the university scheme is the right first stop. If your rent is materially above the cap, you will need a corporate provider as well, or instead.
Indicative cost comparison by monthly rent
These are modelled costs using each provider's published formula. They are rounded and should be treated as indicative until you receive a formal written quote. Annual rent assumes twelve months.
| Provider — formula | £1,000 pcm | £1,500 pcm | £2,000 pcm | £2,500 pcm | £3,000 pcm | £3,500 pcm | £4,000 pcm |
|---|---|---|---|---|---|---|---|
| Housing Hand — 5% to 5.5% of annual rent (UoL partner) | £600 to £660 | £900 to £990 | £1,200 to £1,320 | £1,500 to £1,650 | £1,800 to £1,980 | £2,100 to £2,310 | £2,400 to £2,640 |
| RentGuarantor.com — 3 to 4 weeks' rent | £692 to £923 | £1,038 to £1,385 | £1,385 to £1,846 | £1,731 to £2,308 | £2,077 to £2,769 | £2,423 to £3,231 | £2,769 to £3,692 |
| flatfair — 4 to 6 weeks' rent | £923 to £1,385 | £1,385 to £2,077 | £1,846 to £2,769 | £2,308 to £3,462 | £2,769 to £4,154 | £3,231 to £4,846 | £3,692 to £5,538 |
| Goodlord — one month's rent (cap £3,000 pcm) | £1,000 | £1,500 | £2,000 | £2,500 | £3,000 | Not eligible | Not eligible |
| RentBuddy — one month's rent share, minimum £250, plus VAT | £1,000 + VAT | £1,500 + VAT | £2,000 + VAT | £2,500 + VAT | £3,000 + VAT | £3,500 + VAT | £4,000 + VAT |
| Homeppl Guarantid — 5.8% of annual rent (crawled pages) | £696 | £1,044 | £1,392 | £1,740 | £2,088 | £2,436 | £2,784 |
| Tenancy Guarantor — one month's rent + £14.99 admin | £1,015 | £1,515 | £2,015 | £2,515 | £3,015 | £3,515 | £4,015 |
| Tenanta — illustrative ratio (calculator) | £1,199 to £1,332 | £1,799 to £1,999 | £2,398 to £2,664 | £2,998 to £3,331 | £3,597 to £3,997 | £4,197 to £4,663 | £4,796 to £5,329 |
Two observations from the table. At lower rents (£1,000 to £2,000 per month), Housing Hand under the University of London partner pricing is materially cheaper than the corporate alternatives, often by 30% to 50%. At higher rents (£3,000 per month and above), the picture is fragmented: Housing Hand and RentGuarantor.com remain the most predictable, Goodlord drops out at the cap, and flatfair and Tenanta become substantially more expensive. The relative ranking by cost changes with the rent level. There is no single cheapest provider across the market.
What to ask any provider before you pay
Before you pay a non-refundable fee, ask the provider these questions in writing and keep the answers.
| Question | Why it matters |
|---|---|
| Will my landlord or letting agent accept this provider? | Avoids paying a fee for a guarantor the landlord rejects. |
| Is the fee refundable if the tenancy does not proceed? | Some fees are non-refundable after application or after move-in. |
| What exactly is covered: rent only, damages, legal costs, utilities, council tax? | Coverage differs significantly by provider. |
| Is the guarantee for my share only or the whole joint tenancy? | Critical for student shares and HMOs. |
| What is the maximum monthly rent or total liability cap? | Central London rents can exceed provider limits. |
| How long does the guarantee last under periodic tenancies? | Some products are annual; some cover up to three years; some require renewal. |
| What happens if I leave, the tenancy changes, or my flatmates change? | Some providers require cancellation and a new application. |
| Does the provider pay the landlord first and then recover from me? | You need to understand the debt obligation. |
| Is there a co-signer requirement? | Housing Hand, UK Guarantor, and Homeppl typically require one. |
| Are there agent commissions or referral arrangements? | You should understand whether you are being neutrally informed or commercially referred. |
If the provider will not answer any of these in writing, that itself is the answer.
Documents to prepare — the overseas-student checklist
For overseas students entering central London on a private residential tenancy, the fastest route is to have your documents assembled before viewing or offering. Most providers ask for some combination of the following. Have these ready as PDFs:
Passport or national ID. Right-to-rent share code (UK government scheme) or alternative immigration evidence. University offer letter, enrolment letter, or CAS document. Student ID once issued. Proof of current address in your home country. Bank statements (typically the most recent three months). Scholarship or sponsorship evidence if applicable. Evidence of family contribution if family are paying. Full property and rent details for the proposed tenancy, ideally including the agent's reference.
Housing Hand asks for proof of study, proof of ID, and co-signer details. RentBuddy asks international tenants for immigration documents, share code, or settled or pre-settled status. UCL asks its own students for funding evidence, bank statements, tenancy details, and household income evidence where family support is expected. The exact list varies by provider, but if you have the items above ready you will not be the bottleneck.
Five risks worth understanding before you pay
First, paying a non-refundable fee before landlord acceptance is the most common waste of money in this market. Housing Hand's own student-partner page makes the point: the accommodation provider must accept Housing Hand before the cover is confirmed. Get written acceptance from the landlord or letting agent before paying.
Second, joint-tenancy exposure can survive a guarantor product. Where each joint tenant is responsible for the whole rent and the product only covers your share, you remain personally liable for any flatmate's arrears. Get the exact scope in writing.
Third, rent-only cover is the norm, not the exception. Utilities, council tax, cleaning, and dilapidation deductions usually fall outside the guarantee. If you are taking a property with significant unfurnished or new-build elements, the dilapidation exposure may be material; check.
Fourth, renewal mechanics under post-Renters' Rights Act periodic tenancies are still settling. Tenancies are now rolling rather than fixed-term. Most professional guarantor products were designed when twelve-month fixed terms were the norm. Some now state up-to-three-year cover regardless of tenancy length; some still require annual renewal payments. Confirm the cover length against the (now-periodic) tenancy you are actually signing.
Fifth, you remain personally liable for the rent. A guarantor product transfers cash-flow risk from the landlord to the provider; it does not transfer the debt away from you. The provider will pursue you for any payment they make to the landlord under their cover. Read the recovery clauses in the provider's contract before you sign.
How we handle guarantor questions operationally
For any tenancy we manage, the landlord's requirement is for a suitable guarantor — meaning one the landlord will accept. That is the language in the tenancy file and the language we use in conversation. We are not in a position to require a particular provider, and we will not pretend otherwise to a tenant who would prefer a different one.
In practice, our operational defaults are these. For student tenancies at or below £3,000 per month, we have built and tested a Goodlord Guarantor pathway end-to-end, including international payment from outside the UK and the under-eligibility for the standard income test that Goodlord allows for full-time Higher Education students. That pathway is documented at Student Lettings and we are happy to run it where the tenant chooses it. For student tenancies above £3,000 per month — the typical central London four-bed shared flat at £4,500 to £4,800 per month — Goodlord is not eligible by its own published cap, and one of RentGuarantor.com, Housing Hand, or flatfair is usually the workable route. For overseas tenants whose UK credit file is thin or non-existent, the ranking above (with the central London rent test applied to each candidate) is the starting point. For tenants with a UK-resident friend or family member who would prefer to sign personally rather than pay for a corporate product, a personal guarantor remains the right answer.
If you would like our view on which provider is likely to be accepted on a particular property, ask. We will tell you what we know about the landlord's preferences and any platform integration that affects availability, but the choice is yours.
A note for landlord clients
If you instruct us as your letting agent, the guarantor question is one we will handle openly with the tenant. We do not market a tenancy as guarantor-required-and-must-be-X. We market it as guarantor-required-where-applicable, with the option list above as the tenant's research starting point. That is what the Tenant Fees Act 2019 requires of us. It is also what gives an applicant the confidence that the tenancy they are paying to enter is one they have chosen freely rather than been steered into.
The practical landlord upside of running guarantor questions this way is that the corporate guarantor products that do attach to your tenancy attach because the tenant chose them on the basis of cover and cost — which means the tenant is bought in to making the product work. The downside, such as it is, is that a tenant exercising free choice may pick a smaller or less-known provider than we would have offered as default. Where that happens, we will make the suitability assessment with you — is this provider acceptable to you for this tenancy — and document the acceptance decision before move-in.
Where to look next
Our Student Lettings page sets out the worked operational pathway we have built for full-time Higher Education students choosing the Goodlord Guarantor route, including the international payment workflow, the under-eligibility rules for the income test, the family-payment mechanics, and the China Desk for Mandarin-speaking families. Our Overseas Landlords page is the parallel landlord-facing resource for overseas property owners whose tenancies are most likely to involve a guarantor service. Our Tenants page sets out the end-to-end tenant journey from application to keys. Our Holding Deposits page explains the holding-deposit mechanics that interact with the referencing flow. The Renters' Rights Act 2025 page gives the legal context for why the one-month-in-advance limit removed the old twelve-months-upfront workaround that students previously used.
