Rent to rent is an arrangement where an operator rents a property from its owner, usually for a fixed monthly sum over 3 to 5 years, and then lets it out again, often room by room as an HMO or night by night as serviced accommodation. The operator keeps the difference between what they collect and what they pay the owner and the running costs.

Rent to rent is legal in the UK when it is done with the owner’s full knowledge and every consent in place. The problem is that the most important consent is the one most often missed: the mortgage lender’s. Most buy-to-let mortgages require the property to be let on an assured tenancy to individuals, and a letting to a company that then sublets is a different thing. This page is written for two readers. If you are a landlord who has been approached by a rent-to-rent operator, it covers what your mortgage, insurance and licence position really is. If you are an operator who wants to own rather than rent, it covers how lenders look at your income and experience and how to get your first buy-to-let or HMO mortgage.

How does rent to rent work?

Rent to rent works as a chain of two agreements. The owner signs an agreement with the operator, often called a company let, a management agreement or a commercial lease, under which the operator pays a fixed rent regardless of whether the rooms are occupied. The operator then grants occupation agreements to the people who actually live there. The owner’s income is steady and hands off; the operator takes the void risk, the bills and the day-to-day management in exchange for the margin.

The model is most common with HMOs, where letting five rooms individually produces far more than letting the whole house to one household, and with serviced accommodation, where nightly rates beat a monthly rent in the right location. It is also used by councils and housing associations to source temporary accommodation, which is the most established and least controversial version. Operators are attracted because they can control a property without a deposit or a mortgage. Owners are attracted because they get a fixed rent, often with no agent fees, and someone else handles the tenants. Both sides carry risks that the sales pitch tends to skip.

Party	What they sign	What they get	What they carry
Owner (superior landlord)	Company let, lease or management agreement with the operator	Fixed monthly rent, no void risk, little day-to-day work	Mortgage and insurance breach risk, licence liability, sub-tenants if the deal fails
Rent-to-rent operator	Agreement with owner plus room or nightly lets with occupiers	The margin between income and costs	Voids, bills, compliance, rent owed to the owner whatever happens
Occupiers (sub-tenants)	Tenancy or licence with the operator	A room or whole property	Their deposit and home depend on the operator’s arrangement holding up
Mortgage lender	Nothing with the operator; its mortgage terms bind the owner	Security over the property	A tenancy structure it may never have agreed to

How much does a rent-to-rent operator actually make?

A typical rent-to-rent HMO makes a few hundred pounds a month per property once every real cost is counted, and the margin is far more sensitive to voids and room rates than most training courses admit. Here is an illustrative five-bedroom house outside London, with round numbers so you can follow the arithmetic.

Worked example (illustrative figures, September 2026). The operator agrees to pay the owner £1,400 a month for 5 years. Five rooms are let at £600 a month each, bills included, which is £3,000 a month at full occupancy. Allowing 8% for voids and changeovers reduces that to £2,760. Against it sit: rent to the owner £1,400; energy £280; water £60; broadband £35; council tax £175 (often the operator’s liability in a room-let HMO, but check with the council); cleaning of communal areas £120; repairs and consumables £100; insurance £40; the HMO licence, say £1,000 spread over its 5-year term, about £17 a month; redress scheme and software £30. Total costs are £2,257 a month. The margin is £2,760 minus £2,257, which is £503 a month, or £6,036 a year before tax.

Set-up is not free either. Furnishing five rooms and the communal areas might be £5,000, a deposit and first month to the owner £2,800, and fire safety upgrades £800, so roughly £8,600 before the first tenant moves in. At £503 a month that takes about 17 months to earn back, on a 5-year agreement.

Scenario (same house)	Monthly income after voids	Monthly costs	Monthly margin	Months to recover £8,600 set-up
Base case: £600 rooms, 8% voids	£2,760	£2,257	£503	17
Rooms at £550, 8% voids	£2,530	£2,257	£273	32
£600 rooms, 15% voids	£2,550	£2,257	£293	29
£600 rooms, 8% voids, energy up 40% (£392)	£2,760	£2,369	£391	22
Rooms at £550 and 15% voids	£2,338	£2,257	£81	106

The lesson for both sides: the owner’s £1,400 is fixed, but the operator’s margin can fall by more than 80% on two bad assumptions. When an operator’s margin disappears, the owner’s “guaranteed” rent is only as good as the operator’s balance sheet.

Is rent to rent legal in the UK?

Yes, rent to rent is legal in the UK, provided the owner agrees to it and every party with a legal interest has consented. There is no law banning the model. What makes a particular deal unlawful, or a breach of contract, is usually one of five things: subletting without the owner’s written permission; subletting in breach of the mortgage terms; subletting a leasehold flat in breach of the lease; running an HMO without the required licence or planning permission; and operators misrepresenting themselves to occupiers or owners.

In England, a tenant under an assured periodic tenancy cannot sublet without the landlord’s consent, so an operator who takes an ordinary tenancy and quietly sublets rooms is acting unlawfully. In Wales, anyone letting or managing residential property needs to be registered and licenced with Rent Smart Wales. In Scotland, a business carrying out letting agency work must be on the Scottish Letting Agent Register. Operators doing letting or property management work in England also need to belong to a government-approved redress scheme. The model is legal. A lot of the deals being pitched are not structured properly, and the owner is the one who usually discovers that too late.

Does my buy-to-let mortgage allow rent to rent?

In most cases, no, not without the lender’s written consent, and many lenders will refuse it. A standard buy-to-let mortgage offer requires the property to be let on the lender’s approved tenancy type, which in England is now an assured periodic tenancy to individuals. A letting to a company that then sublets, a lease to an operator, or any arrangement where the person paying you is not the person living there, is outside those terms unless the lender has agreed to it.

Read three parts of your mortgage paperwork before you sign anything: the tenancy conditions in the offer, the clause on subletting or parting with possession in the mortgage conditions, and any restriction on HMO or short-term letting use. Letting the property on terms your lender has not approved can be a breach of the mortgage, which in the worst case lets the lender demand repayment or appoint a receiver of rent. It also gives the lender grounds to refuse a product transfer later.

If your lender will not consent, the fix is usually a remortgage to a lender whose criteria accept the arrangement, which narrows the market sharply and often means a specialist rate. Our corporate lease buy-to-let guide covers lenders that accept lets to companies, and our guaranteed rent mortgage page covers the same question for guaranteed rent schemes.

Which lenders accept company lets and rent to rent?

Very few mainstream lenders accept a letting to a rent-to-rent operator, and several say so explicitly. Criteria that allow company lets are usually written for employers housing their own staff, not for operators subletting to the public. The table below is taken from each lender’s published intermediary criteria, checked in September 2026. Criteria change often and each case is still underwritten individually, so treat this as a starting point, not an approval.

Lender	Company lets	Guaranteed rent / subletting	HMO position	What it means for rent to rent
Barclays	Contractual tenancy of 6 months to 3 years that names the employee who will occupy, with no statutory rights to continue	Subletting only covered for local authority and housing association lettings	HMOs not acceptable	An operator subletting rooms does not fit
Coventry Building Society	Lets to corporate bodies accepted, maximum term 36 months	Where the corporate body sublets to individuals in England, the Renters’ Rights Act applies; tenancy must include a covenant to maintain the property	Mandatory-licence HMOs not acceptable (except Scotland); additional-licence HMOs up to 4 tenants	One of the few mainstream lenders that contemplates subletting, but not a large licenced HMO
The Mortgage Works	Only for use by the company’s employees, where the company has more than 1,000 UK staff	Guaranteed rent schemes not accepted	HMO range available, licensing required where applicable	A rent-to-rent operator will not meet the employer test
Leeds Building Society (criteria effective 24 August 2026)	Limited company BTL tenancy must be in the name of the company and the tenant	Property must be let on an assured periodic tenancy	HMO applicants need 2 years’ current landlord experience; limited companies not accepted for HMO	Not suited to a rent-to-rent letting
Specialist BTL lenders	Some consider company lets case by case	No published rent-to-rent criteria found; appetite depends on the operator, the lease and the valuer	Wider HMO appetite	Possible, but needs full disclosure and an underwriter’s agreement before you sign with the operator

Kent Reliance stopped taking new buy-to-let business in December 2025 and Precise’s buy-to-let range has moved to OSB’s Rely brand, so older forum advice naming those lenders is out of date.

What does the Renters’ Rights Act change for rent to rent?

The Renters’ Rights Act 2025, in force in England from 1 May 2026, makes rent to rent materially riskier for owners. Three changes matter most.

First, the owner can now be pursued for the operator’s failures. In Rakusen v Jepson in 2023 the Supreme Court held that a rent repayment order could only be made against the sub-tenant’s immediate landlord, which in a rent-to-rent deal was the operator. Section 103 of the Act reverses that, so sub-tenants can seek a rent repayment order against a superior landlord. The maximum order has also doubled from 12 to 24 months’ rent, and civil penalties for the most serious breaches now reach £40,000. If an operator runs your house as an unlicensed HMO, you are exposed.

Second, section 21 is gone and all tenancies in England are periodic. An operator can only end an occupier’s tenancy on a statutory ground, and the grounds for possession when a superior lease ends are limited to specified landlord types such as supported accommodation providers and council-owned companies. A private operator generally cannot rely on them.

Third, when the operator’s agreement ends, lawful sub-tenants on assured tenancies can become the owner’s direct tenants under section 18 of the Housing Act 1988. The owner can end the deal and inherit five tenants, their deposits and the compliance history. Get specialist legal advice on the structure before signing.

Who holds the HMO licence in a rent-to-rent deal?

The HMO licence is held by whoever the council decides is the most appropriate person, and in a rent-to-rent deal that is often the operator, because they collect the rents and manage the property. It can equally be the owner. Either way, the owner is not off the hook: the licence holder must be a fit and proper person, and the owner may still be treated as a person having control of the property.

Mandatory licensing in England applies to properties occupied by 5 or more people forming 2 or more households. Many councils also run additional licensing schemes that catch smaller HMOs, and selective licensing that catches single lets in designated areas. Fees, conditions and room size rules vary by council, so check with your local authority rather than relying on another town’s figures. Planning is a separate question: in areas with an Article 4 direction, converting a family house into a small HMO needs planning permission, and larger HMOs always need it. An operator who cannot show you the licence application and the planning position in writing is asking you to carry their risk.

If you plan to own and run HMOs yourself, our HMO mortgage guide covers licensing, valuation and lender experience rules in detail.

What insurance does a rent-to-rent property need?

A rent-to-rent property needs landlord buildings insurance that knows about the arrangement, plus the operator’s own liability and contents cover. Standard landlord policies assume the property is let to named tenants on a normal tenancy. If the insurer is not told that the property is let to a company, sublet by the room, used as an HMO or let nightly, a claim can be reduced or refused for non-disclosure.

The owner should tell their insurer in writing about the operator, the occupancy type and the number of occupiers, and get confirmation that cover continues. The operator should hold public liability insurance, contents cover for the furniture they supply, and ideally rent guarantee or business interruption cover so the owner’s rent survives a void period. Serviced accommodation needs a policy written for short-term guests, which is a different product again. Ask for copies of every certificate before handing over keys, and diary the renewal dates, because a lapsed operator policy is one of the most common gaps landlords only discover after a fire or flood.

What should a rent-to-rent agreement include?

A rent-to-rent agreement should make the operator responsible for everything the owner is legally exposed to, and give the owner a clean exit. A two-page template off a training course will not do that. As a minimum, have a solicitor check the following before you sign.

Clause or check	Why it matters
Written mortgage lender and freeholder consent attached	Protects you from a breach of your mortgage or lease
Permitted use and maximum occupiers stated	Stops a single let becoming an unlicensed HMO or nightly let
Licence holder named and licensing obligations on the operator	Rent repayment orders can now reach superior landlords
Repair and maintenance split, with inspection rights every 3 months	You need to see the condition of your own asset
Gas, electrical, fire and EPC compliance evidence delivered to you	You remain liable for many safety obligations
Rent deposit of at least one month, and a personal guarantee from the directors	Operator companies are often newly formed with no assets
Insurance obligations with copies of policies	Non-disclosure can void your cover
Deposit protection and right to rent checks for every occupier	Failures follow the property, not just the operator
End-of-term plan: vacant possession or transfer of tenancies with full records	Under section 18 you may inherit the sub-tenants
Break clause for non-payment or compliance failure	Lets you act before arrears mount

What are the red flags and scams in rent to rent?

The biggest red flag is an operator who tells you your mortgage lender does not need to know. That is not a technicality; it is asking you to take on the risk of a mortgage breach so their deal works. Other warning signs are consistent across the complaints that reach redress schemes and the courts.

Red flag	What to do
“No need to tell your lender or insurer”	Walk away, or get written consent yourself before signing
Company formed in the last few months, no accounts filed	Check Companies House, ask for directors’ personal guarantees
No redress scheme membership or Rent Smart Wales licence	Ask for the membership number and verify it
Rent offered well above local market	Model their margin; an unrealistic rent usually ends in arrears
Vague about who holds the HMO licence	Require the licence or application in writing
Wants the property “as is” with no inspection rights	Insist on quarterly inspections in the agreement
Training course “deal packagers” charging finder’s fees	Check the operator directly, not the packager
Pressure to sign quickly	A good operator will wait for your solicitor and lender

Operators should watch for scams too: paid “deal sourcing” of properties whose owners never agreed, and courses that promise multiple properties in months. If you are paying a sourcer, confirm the owner’s identity and the title at the Land Registry before any money moves.

Can a rent-to-rent operator get a mortgage to buy property?

Yes. Many operators use rent to rent as a stepping stone into ownership, and the lending market does accommodate that, but lenders see the operator’s history differently from how the operator sees it. There are three questions every lender asks.

Is your income provable? Rent-to-rent profit is business income. If you trade as a sole trader, lenders usually want one to two years of SA302s and tax year overviews. If you trade through a limited company, they look at your salary and dividends, or in some cases your share of company profit. Many buy-to-let lenders set a minimum personal income, commonly around £25,000, though some specialist lenders have none.

Do you have landlord experience? This is where operators are often surprised. Many lenders define landlord experience as owning a let property, not managing one, so running ten rent-to-rent rooms may not count as HMO experience. Leeds Building Society, for example, asks for 2 years’ current landlord experience for HMO lending. Some specialists will look at management experience on its merits, with evidence.

Does the property stack up? Buy-to-let affordability is based on the rent, tested against a stressed interest rate. Your own deposit, usually 25%, has to come from provable savings or other legitimate sources.

What is the best route from rent to rent into ownership?

For most operators the lowest-friction route is a single let or a small HMO bought in a limited company, followed by larger HMOs once you have a track record as an owner. Jumping straight to a seven-bed licenced HMO as a first purchase narrows the lender list to a handful of specialists and usually costs more.

Worked example: first purchase. An operator buys a three-bed terrace for £200,000 in a special purpose vehicle company, with a 25% deposit of £50,000 and a mortgage of £150,000. A lender using a 125% interest cover ratio at a 5.5% stress rate needs the rent to be at least £150,000 x 5.5% x 125% / 12, which is £859.38 a month. Let as a single let at £1,100, it passes comfortably. Let as a four-room small HMO the gross rent is higher, but the lender may value it on a bricks-and-mortar basis and will want licensing and planning confirmed. Rates and stress tests vary by lender and product, so run your own figures with our buy-to-let mortgage calculator.

Route	Suits	Watch out for
Single let in personal name	Basic-rate taxpayers, first purchase	Higher stress tests for higher-rate taxpayers; mortgage interest relief limited to a 20% tax credit
Single let or small HMO in an SPV	Operators planning a portfolio	SPV-specific products, personal guarantees, accountant set-up
Licenced HMO as first purchase	Operators with strong income and a large deposit	Fewer lenders, experience rules, higher rates
Buy the property you rent to rent from the owner	Operators with a known, proven property	Valuation, a clean end to the rent-to-rent agreement, sub-tenant transfer
Let your own home and buy another	Operators who own their residence	Consent to let or remortgage on the current home

Our guides to limited company buy-to-let mortgages, SPV mortgages and let to buy mortgages cover each route. Once you own four or more mortgaged buy-to-lets, portfolio underwriting applies, covered in our portfolio landlord mortgage guide. For the fundamentals, start with buy-to-let mortgages.

Why do rent-to-rent mortgage cases get declined, and what is the fix?

Rent-to-rent mortgage cases usually fail on disclosure and structure, not on the numbers. These are the declines we see most, on both sides of the arrangement.

Reason for decline	Who it affects	The fix
Valuer or underwriter finds a company let the lender does not accept	Landlord remortgaging	Disclose it up front and place the case with a lender that accepts the structure, or end the arrangement first
Product transfer refused because the letting breaches the mortgage terms	Landlord at end of deal	Remortgage to a lender with suitable criteria; allow time for a full application
Rent-to-rent management not accepted as landlord experience	Operator buying an HMO	Start with a single let or small HMO, or apply with a lender that assesses management experience
Less than 2 years’ accounts, or income drawn inconsistently	Operator	Use a lender that accepts 1 year, or restructure salary and dividends with your accountant before applying
Deposit came from rent-to-rent deposits held for occupiers	Operator	Only use your own funds; protected tenant deposits are not yours to invest
Unlicensed HMO or no planning in an Article 4 area	Both	Obtain the licence and planning position before applying
Arrears or CCJs from a failed rent-to-rent deal	Operator	Specialist lenders assess adverse credit case by case; settle and document it

Illustrative Knox case: from operator to owner

This is an anonymised, illustrative case based on the type of scenario we see. Names and figures are changed.

A Manchester operator in her early thirties had run three rent-to-rent HMOs through her limited company for two years, with filed accounts showing about £38,000 of profit a year. She had £60,000 saved and wanted to buy a six-bed licenced HMO as her first property. Two lenders had already told her by phone that she had “no landlord experience”.

The issue was sequencing, not affordability. We showed her that a six-bed licenced HMO as a first purchase limited her to a very small number of lenders at higher rates, while a four-bed small HMO in a new SPV, outside an Article 4 area and below the mandatory licensing threshold for her council, opened a far wider market. She bought a £190,000 property with a 25% deposit, used the remaining £12,500 for stamp duty at the higher rates and purchase costs, with fit-out funded from rent-to-rent profits, and used her company accounts and management records to support the application. With a year of ownership behind her, the larger HMO becomes a realistic next step, and she is renegotiating one of her rent-to-rent agreements as a possible purchase from the owner.

Rent to rent: frequently asked questions

Is rent to rent legal in the UK?

Yes. Rent to rent is legal when the owner agrees and all consents are in place, including the mortgage lender, any freeholder, licensing and planning. It becomes unlawful or a breach of contract when a tenant sublets without permission, an HMO runs without a licence, or the owner’s mortgage terms are broken.

Do I need my mortgage lender’s permission for rent to rent?

Yes. Most buy-to-let mortgages require an assured tenancy to individuals, so letting to an operator who sublets needs written lender consent. Many lenders refuse; The Mortgage Works does not accept guaranteed rent schemes and Barclays does not accept HMOs. If consent is refused, a remortgage to a lender that accepts the structure is usually the only option.

Why would a landlord agree to rent to rent?

Mainly for a fixed rent with no voids, no agent fees and little management. That appeal is real, but since 1 May 2026 the Renters’ Rights Act lets sub-tenants seek rent repayment orders against superior landlords, and the owner can inherit sub-tenants when the deal ends. The fixed rent needs weighing against those risks.

Who is responsible for the HMO licence in rent to rent?

The council licences the most appropriate person, often the operator because they manage the property and collect rent. The owner can still be treated as a person having control, and rent repayment orders can now reach superior landlords, so the owner should see the licence and the conditions in writing.

Can rent-to-rent experience count as landlord experience for a mortgage?

Sometimes. Many lenders define landlord experience as owning a let property, so managing rent-to-rent rooms may not count. Some specialist lenders will consider documented management experience. Starting with a single let or small HMO is often the simplest way to build an ownership track record.

Can I get a mortgage to buy a property as a rent-to-rent operator?

Yes. Lenders will assess your rent-to-rent profit as self-employed or company income, usually wanting one to two years of accounts, a deposit of around 25% from your own funds, and rent that passes the lender’s stress test. Many operators buy through a limited company SPV.

What happens to the tenants when a rent-to-rent agreement ends?

It depends on the structure. Lawful sub-tenants on assured tenancies can become the owner’s direct tenants under section 18 of the Housing Act 1988. Since section 21 was abolished, removing them needs a statutory ground. The agreement should require full records and a plan for tenancies at the end of the term.

Is rent to rent a good business?

It can be, but margins are thin and fragile. In our illustrative five-bed example the operator makes about £503 a month, which falls to £81 if room rents drop by £50 and voids rise to 15%. It works for operators with strong local demand data, cash reserves and full compliance, and poorly for anyone relying on a course’s projections.
