Yes, you can rent out your first home in England, but owning the property does not automatically give you the right to put it on the rental market.
If the property has a residential mortgage, you will normally need your lender’s permission before letting it. You may also need consent from a freeholder, housing association or scheme administrator, depending on how the property was bought.
Becoming a landlord also creates tax, insurance, safety and tenancy-law obligations. These became particularly important after the Renters’ Rights Act reforms took effect on 1 May 2026, abolishing Section 21 for most private tenancies and moving assured tenancies onto a periodic system.
There is therefore a major difference between being allowed to own a property and being allowed to rent it out.
This article focuses mainly on England, because tenancy law differs across the UK.
Can You Legally Rent Out Your First Home?
Yes. There is no general rule saying that someone’s first property can never become a rental property.
However, before handing the keys to a tenant, homeowners should check four separate areas:
- Mortgage permission – residential mortgage borrowers normally need their lender’s approval.
- Lease or ownership scheme restrictions – leasehold, Shared Ownership, Help to Buy and First Homes properties can carry additional conditions.
- Insurance – ordinary owner-occupier home insurance may not provide appropriate cover once tenants move in.
- Landlord law – once the whole home is rented to tenants, the owner takes on the legal responsibilities of a landlord.
GOV.UK specifically states that homeowners with a mortgage must obtain permission from their mortgage lender before renting out the property.
The correct route therefore depends heavily on why you are moving out and how long you expect the property to remain rented.
| Your situation | Route commonly considered | Main issue to check |
| Moving temporarily for work | Consent to let | Lender’s time limit and fees |
| Moving in with a partner but may return | Consent to let | Whether the lender treats the move as temporary |
| Keeping the property permanently as an investment | Buy-to-let mortgage | Equity, rental coverage and affordability |
| Buying another home while keeping this one | Let-to-buy | Mortgage affordability and higher-rate SDLT |
| Staying in the property and renting a room | Lodger arrangement | Mortgage, lease and Rent a Room rules |
| Mortgage already repaid | No lender consent normally required | Lease, scheme, insurance and landlord rules still apply |
| Need equity from the first home for another purchase | Sale or let-to-buy may be considered | Cash requirement, tax and borrowing capacity |
There is no single option that fits every homeowner. The lender’s mortgage conditions, the reason for the move and whether the owner intends to return are all significant.
Can You Rent Out a House on a Residential Mortgage?
A residential mortgage is normally granted on the understanding that the borrower will occupy the property as their home.
Renting the whole property without telling the lender can therefore breach the mortgage conditions.
For a temporary move, homeowners may be able to request consent to let rather than immediately replacing their residential mortgage with a buy-to-let product.
Consent to let means the lender gives written permission for the existing residential mortgage to remain in place while the property is rented for an agreed period.
The conditions differ considerably between lenders.
For example, NatWest currently requires the mortgage to have been held for at least six months and charges a £120 initial fee plus a £120 annual fee. HSBC generally requires six months and describes consent to let as a temporary arrangement of up to 27 months. The Co-operative Bank currently requires its mortgage to have been in force for at least 12 months.
This is why statements such as “you must live in your first home for six months before renting it” are misleading.
There is no universal six-month landlord law. It is commonly a mortgage-lender condition.
Homeowners considering a permanent move into the rental market may also want to understand how buy-to-let interest-only mortgages work before comparing their longer-term financing options.
What Is the Difference Between Consent to Let and a Buy-to-Let Mortgage?
Consent to let and buy-to-let mortgages solve different problems.
Consent to Let
Consent to let is normally intended for borrowers whose circumstances have changed after taking out a residential mortgage.
Common situations include:
- Temporary job relocation
- Moving abroad for work
- Moving in with a partner
- Caring for a relative
- Temporary accommodation elsewhere
- Testing whether a permanent move is suitable
The lender does not have to approve the request.
It may impose conditions involving the mortgage history, loan-to-value ratio, rental income, property type and tenancy arrangement.
Buy-to-Let Mortgage
A buy-to-let mortgage is specifically intended for a property being used as a rental investment.
For someone who does not expect to return to their first property, a buy-to-let mortgage may be more consistent with the property’s long-term use than repeatedly seeking temporary consent.
Homeowners can compare the mechanics of landlord borrowing in the site’s guide to buy-to-let mortgage rates and lending requirements.
Consent to Let vs Buy-to-Let
| Feature | Consent to let | Buy-to-let |
| Main purpose | Temporary letting | Longer-term rental |
| Existing residential mortgage | Usually retained | Usually replaced or switched |
| Time limit | Often temporary | Designed for ongoing letting |
| Rental affordability test | Depends on lender | Usually important |
| Interest rate | Existing rate may remain or be adjusted | Buy-to-let pricing applies |
| Fees | Lender-specific | Product, valuation and legal costs may apply |
| Returning home | Usually expected or possible | Not normally central to the product |
A third possibility is let-to-buy, where the existing home becomes a rental while the owner takes out residential borrowing for a new main home.
How Long Must You Live in Your First Home Before Renting It Out?
There is no single UK rule saying every homeowner must occupy a property for six months, 12 months or any other fixed period before renting it out.
Mortgage lenders make their own decisions.
Current examples demonstrate the variation:
| Example lender | Minimum mortgage period before consent |
| NatWest | Generally 6 months |
| HSBC | Generally 6 months |
| Virgin Money | Generally 6 months |
| Bank of Scotland | Generally 6 months |
| The Co-operative Bank | 12 months |
NatWest also charges £120 initially and £120 annually, while Virgin Money currently states a £125 consent-to-let fee and limits consent to 12 months before an extension is considered.
These examples are useful for understanding how lenders approach accidental landlords, but borrowers should check their own mortgage terms rather than assuming another lender’s policy applies.
Can You Rent Out Your First Home for Just One Year?
You can intend to rent the home for approximately one year, but you should no longer assume that a 12-month tenancy guarantees the tenant will leave exactly one year later.
That is one of the most important changes for accidental landlords in 2026.
From 1 May 2026, new assured tenancies in England generally operate as periodic assured tenancies rather than fixed-term ASTs. Tenants can normally end their tenancy by providing two months’ notice.
The landlord cannot simply write “12 months” into an agreement and automatically recover the home on that date.
If the landlord genuinely needs the property back as their own home, Ground 1 can be used.
However:
- Possession for moving back in cannot be required within the first 12 months of a new tenancy.
- Ground 1 normally requires at least four months’ notice.
- If the tenant does not leave after a valid notice expires, possession may still require court proceedings.
- After using Ground 1 to recover possession, restrictions generally prevent re-letting or marketing the property to let during the 12-month restricted period.
A notice can potentially be served before the first 12 months have passed, provided the possession date itself complies with the protected period and other legal requirements.
So an owner thinking, “I’ll rent the house for exactly one year and move back in on day 366,” should not treat that timetable as guaranteed.
Court timescales and the tenant’s actual departure date can change the practical result.
How Has the Renters’ Rights Act Changed Things for First-Time Landlords?
The reforms that took effect on 1 May 2026 substantially changed private renting in England.
Section 21 “no-fault” eviction was abolished for the affected private rented sector. Existing ASTs moved into the new assured periodic framework, and new assured tenancies generally operate on a rolling basis.
This matters particularly to homeowners who previously viewed letting their first property as a simple six- or 12-month temporary arrangement.
The mortgage lender might grant consent for 12 months, but the tenancy itself operates under housing law rather than according to the lender’s administrative consent period.
Moving Back Into the Property
If the owner needs the home back for themselves or certain close family members, Ground 1 provides a possession route.
The property cannot generally be recovered under this ground during the first 12 months of a new tenancy, and the notice period is four months.
Tenants, meanwhile, can normally leave an assured periodic tenancy by providing two months’ notice.
This creates an important planning issue.
A lender may give 12 months of consent to let, but:
- The tenant could leave considerably earlier.
- The landlord cannot guarantee possession exactly when the lender’s consent expires.
- Court action may be necessary if a tenant remains after valid possession proceedings begin.
Temporary landlords therefore need to plan for both early vacancy and delayed possession.
Landlord Registration and Ombudsman
The Renters’ Rights Act also creates a national private rented sector database.
The government’s implementation roadmap says rollout will begin from late 2026, with landlords ultimately required to register themselves and their rented properties. An annual fee is planned, but the government has not yet confirmed the final fee in the official implementation guidance.
Claims that the charge is definitely £65 per property should therefore not currently be treated as settled government policy.
A mandatory Private Rented Sector Landlord Ombudsman is also planned, with compulsory landlord membership expected in 2028.
How Much Rent Would You Need to Cover the Mortgage?
Landlords should not assume that collecting enough rent to equal the normal monthly mortgage payment will automatically satisfy a lender.
Buy-to-let and some consent-to-let affordability assessments use an interest coverage ratio, or ICR.
For example, Virgin Money’s current consent-to-let criteria require the property to be self-financing, with rental income covering 125% of stressed mortgage interest, using the higher of a 5% interest rate or the mortgage rate plus one percentage point.
Consider this simplified illustration:
Stressed monthly mortgage interest: £1,000
At 125% ICR:
£1,000 × 125% = £1,250
The lender would therefore require around £1,250 monthly rent under that particular test.
That does not mean £250 is the landlord’s profit.
From the rent may still come:
- Maintenance
- Landlord insurance
- Letting-agent fees
- Safety checks
- Licensing
- Service charges
- Ground rent where applicable
- Empty periods
- Repairs
- Tax
Some buy-to-let lenders use higher ICR requirements, particularly for higher-rate taxpayers, so the exact mortgage calculation should always be checked with the lender.
Could Renting Your First Home Actually Make a Profit?
Consider a property producing £1,250 per month in rent.
That creates annual gross rental income of £15,000.
Suppose an illustrative landlord has:
- £12,000 annual mortgage interest/cost
- £1,800 of other annual operating expenses
- 2% annual rent growth
- 2% annual growth in operating expenses
- No change to the mortgage cost
The example would look like this:
| Year | Gross rent | Mortgage cost | Other costs | Pre-tax cash surplus | Cumulative surplus |
| 1 | £15,000 | £12,000 | £1,800 | £1,200 | £1,200 |
| 2 | £15,300 | £12,000 | £1,836 | £1,464 | £2,664 |
| 3 | £15,606 | £12,000 | £1,873 | £1,733 | £4,397 |
| 4 | £15,918 | £12,000 | £1,910 | £2,008 | £6,405 |
| 5 | £16,236 | £12,000 | £1,948 | £2,288 | £8,693 |
This is only an illustration, not a profit forecast.
It excludes income tax, major repairs, mortgage rate changes, void periods beyond those built into the assumed expenses, house-price movements and buying or selling costs.
A single £5,000 boiler, roof or structural repair could materially change the result.
What Tax Do You Pay When Renting Out Your First Home?
Rental income can create an Income Tax liability even when the landlord still thinks of the property as “my first home”.
Tax is generally based on the property’s taxable rental profit rather than simply the amount of cash left after the mortgage payment.
Homeowners should understand allowable costs before estimating their liability. The guide to expenses landlords can claim provides further detail on common property-business expenses.
Mortgage Interest and Section 24
Individual residential landlords generally cannot deduct mortgage finance costs from rental income in the same way as ordinary operating expenses.
Instead, finance-cost relief is given through a tax reduction.
This is commonly referred to as the Section 24 mortgage interest restriction. More detail is available in the site’s explanation of Section 24 for landlords.
HMRC currently explains that the residential finance-cost restriction provides basic-rate tax relief rather than allowing individuals to deduct the entire mortgage interest cost from taxable rental profit.
There is an important forthcoming change.
From 6 April 2027, separate property-income tax rates will be introduced at:
| Property income band | Rate from 6 April 2027 |
| Property basic rate | 22% |
| Property higher rate | 42% |
| Property additional rate | 47% |
Finance-cost relief will also be calculated at the 22% property basic rate from that date.
Homeowners who want more detail on the distinction can also read the site’s guide to mortgage interest tax relief on rental property.
Will Making Tax Digital Apply to Rental Income?
Potentially.
Making Tax Digital for Income Tax began applying from 6 April 2026 to qualifying sole traders and landlords with total qualifying self-employment and property income above £50,000.
The threshold then falls to:
| Start date | Qualifying income threshold |
| 6 April 2026 | More than £50,000 |
| 6 April 2027 | More than £30,000 |
| 6 April 2028 | More than £20,000 |
Those within the rules need compatible software, digital records and quarterly updates to HMRC.
The thresholds relate to qualifying income, not simply the landlord’s taxable profit after every expense.
Could You Pay Capital Gains Tax When You Eventually Sell?
Possibly.
A home that has always qualified fully as someone’s main residence may benefit from Private Residence Relief.
However, once the owner moves out and rents the property, part of a later gain can potentially fall outside full relief.
HMRC currently allows the final nine months of ownership to qualify for Private Residence Relief where the property has been the owner’s only or main residence at some point.
For individuals, the Capital Gains Tax annual exempt amount is currently £3,000.
Applicable CGT rates are currently 18% and 24%, depending on the taxpayer’s circumstances and available basic-rate band.
Where CGT is due following a UK residential-property disposal, the tax generally has to be reported and paid within 60 days of completion.
This is one reason why an owner planning to keep a former home for many years should consider future tax exposure rather than looking only at monthly rental cash flow.
Could Keeping the First Home Increase Stamp Duty on Your Next Home?
Yes. This is frequently confused with remortgaging.
Simply changing the mortgage on an existing property to a buy-to-let product does not normally create SDLT just because the mortgage product changed. SDLT is fundamentally a tax on chargeable land/property transactions. A transfer of ownership or another transaction involving chargeable consideration can produce a different result.
The major SDLT issue normally arises when the owner keeps the first property and buys another residential property.
In England and Northern Ireland, buying an additional residential property normally attracts rates five percentage points above the standard residential rates.
For example, the current higher-rate SDLT on a £300,000 additional property is:
| Portion | Rate | SDLT |
| First £125,000 | 5% | £6,250 |
| £125,001–£250,000 | 7% | £8,750 |
| Remaining £50,000 | 10% | £5,000 |
| Total | £20,000 |
This matches HMRC’s current example.
Someone considering let-to-buy therefore needs to assess not just whether the original home generates rent, but also how keeping it affects the cost of purchasing the next home.
Can You Rent Out Your First Home and Take in a Lodger Instead?
A lodger can offer a very different arrangement because the homeowner continues to live in the property as their main home.
Under the Rent a Room Scheme, a resident landlord can currently receive up to £7,500 per year tax-free from furnished accommodation in their home. The allowance is normally halved to £3,750 where another person shares the rental income.
The scheme does not generally apply if the homeowner moves elsewhere and lets the entire property.
Mortgage borrowers should still check their lender’s terms before taking in a lodger, and leaseholders should check whether their lease imposes restrictions.
What Happens If You Rent Out Your Home Without Telling the Mortgage Lender?
Letting without required permission can put the borrower in breach of the mortgage agreement.
The precise consequences depend on the lender and mortgage contract.
They should not be dismissed as a theoretical problem.
For example, Lloyds states that where a property is rented without agreement it may apply an added interest rate, backdate additional interest and prevent further borrowing. The Co-operative Bank warns that unauthorised letting breaches its mortgage conditions and says it may be entitled to commence possession proceedings.
Possible lender responses therefore include:
- Requesting information about the tenancy
- Charging additional interest or fees
- Refusing further borrowing
- Requiring a switch to an appropriate mortgage
- Treating the letting as a breach of mortgage conditions
- In serious cases, taking enforcement action permitted by the mortgage terms
A borrower who has already let the property without permission should generally contact the lender rather than trying to conceal the tenancy.
Do You Need Landlord Insurance?
Standard home insurance is designed around owner occupation.
Once tenants occupy the property, the risk profile changes.
The homeowner should inform the insurer before letting because failing to disclose the change of use could leave the property inadequately covered.
Landlord insurance itself is not a universal statutory requirement, but lenders, leases or individual circumstances can make suitable insurance effectively essential.
Landlord policies may include buildings protection, landlord contents, property-owner liability, legal expenses or rent protection depending on the policy.
The site’s guide to landlord insurance in the UK explains the different forms of protection available.
What Legal Checks Must a First-Time Landlord Complete?
Becoming an accidental landlord does not reduce the legal duties attached to renting a property.
Before letting a home in England, landlords should check the following.
| Requirement | Typical obligation |
| Gas safety | Annual checks on landlord-supplied gas appliances and flues |
| Electrical safety | Inspection/testing generally at least every 5 years |
| EPC | Provide a valid Energy Performance Certificate and meet applicable minimum standards |
| Smoke alarms | Required on storeys used as living accommodation |
| Carbon monoxide alarms | Required where the regulations apply |
| Deposit protection | Protect qualifying tenancy deposits in an approved scheme |
| Right to Rent | Check qualifying adult occupiers in England |
| Property condition | Keep the home safe and free from serious hazards |
| Licensing | Check local selective, additional or HMO licensing |
| Insurance | Tell the insurer that the property is being rented |
Electrical installations in privately rented homes must generally be inspected and tested by a qualified person at least every five years.
Gas appliances and flues supplied by the landlord normally require annual gas-safety checks.
Deposits for assured periodic tenancies must normally be placed into an approved tenancy-deposit scheme within 30 days of receipt.
GOV.UK also lists EPC provision, Right to Rent checks, deposit protection and property safety among the core landlord responsibilities.
Local licensing is especially important because the requirements can differ substantially between councils.
Can You Rent Out a Leasehold First Home?
Possibly, but the lease needs to be checked.
Many leases contain restrictions on underletting or subletting.
Some allow it automatically, some require the freeholder or managing agent to be notified, some require formal consent, and others restrict particular types of letting.
Government leasehold guidance notes that many leases require permission before subletting and that breach of a lease covenant can have serious consequences.
Mortgage consent does not override the lease.
A leaseholder may therefore need both lender consent and freeholder consent before proceeding.
Can You Rent Out a Shared Ownership Home?
Shared Ownership is much more restrictive.
Someone who owns less than 100% of a Shared Ownership property normally cannot simply move elsewhere and rent out the whole home.
Current government guidance says an owner can normally take in a lodger while continuing to live there, but letting the entire property usually requires the housing provider’s permission unless the owner has staircased to 100%.
Permission to rent the entire property is typically reserved for exceptional circumstances.
Where permission is granted, the shared owner still becomes the tenant’s landlord and the Renters’ Rights Act rules apply.
Can You Rent Out a Help to Buy Property?
Help to Buy Equity Loan properties can also carry restrictions.
Government guidance states that Help to Buy Equity Loan owners are not allowed to sublet the whole home without consent.
The mortgage lender may impose separate requirements.
Anyone who still has a Help to Buy equity loan should therefore check with both the relevant scheme administrator and the mortgage lender before offering the property to tenants.
Can You Rent Out a Property Bought Through the First Homes Scheme?
The First Homes scheme should not be confused with simply owning your “first home”.
First Homes is a specific affordable-housing scheme in England.
Under the scheme, owners are generally allowed to rent their First Home for an aggregate period of up to two years.
The period does not have to be continuous.
The homeowner must notify the relevant local authority and also comply with mortgage conditions.
Longer letting may be permitted in exceptional circumstances, including situations such as:
- Short-term job relocation
- Armed Forces deployment
- Relationship breakdown
- Domestic abuse
- Redundancy
- Caring responsibilities
Local-authority permission is required for an extension beyond the normal aggregate two-year allowance.
What Should You Check Before Becoming an Accidental Landlord?
A homeowner considering renting their first property can use the following sequence before advertising it.
- Mortgage: Read the mortgage conditions and obtain written consent to let where required.
- Lease or scheme: Check leasehold restrictions, Shared Ownership conditions, Help to Buy obligations or First Homes rules.
- Rental figures: Obtain realistic rental evidence and test whether the rent satisfies the lender’s affordability requirements.
- Tax: Estimate taxable property income rather than calculating profit from rent minus the entire mortgage payment.
- Insurance: Tell the existing insurer and arrange suitable landlord cover.
- Safety: Complete required gas, electrical, alarm and EPC checks.
- Licensing: Check the property’s local council area for selective, additional or HMO licensing.
- Tenancy documentation: Make sure the tenancy complies with the post-May 2026 assured periodic tenancy regime.
- Deposit: Use an approved protection scheme where required.
- Return plan: If you expect to move back in, understand Ground 1, the 12-month protected period and four-month notice requirement before promising yourself a specific return date.
Is Renting Out Your First Home Better Than Selling It?
The answer depends on the owner’s circumstances rather than simply whether local rents appear high.
Renting may allow the owner to retain the property while producing income, but it also creates mortgage, tax, maintenance, regulatory and possession risks.
Selling may release equity and remove landlord responsibilities, but it also ends exposure to future rental income and future movements in the property’s value.
A useful comparison should therefore include:
| Question | Rent out | Sell |
| Keep exposure to property value? | Yes | No |
| Receive rental income? | Potentially | No |
| Landlord responsibilities? | Yes | No |
| Equity immediately released? | Usually limited | Usually yes after mortgage/costs |
| Possible higher-rate SDLT on next home? | Yes, if first home is retained | Often avoided if replacing main residence under the rules |
| Rental-income tax? | Potentially | No ongoing rental income |
| Future CGT considerations? | Potentially | Depends on circumstances |
| Maintenance risk retained? | Yes | No after completion |
The most useful calculation is therefore net return after mortgage costs, tax, maintenance, insurance, voids, compliance and transaction costs, rather than gross rent alone.
FAQs About Renting Out Your First Home
Can I Rent Out My First House With a Normal Mortgage?
Possibly, but most residential mortgage borrowers need written permission from their lender before renting the whole property.
Can I Rent My House Out After Six Months?
You may be able to. Six months is a common lender requirement rather than a universal legal rule. Some lenders require longer periods.
Do I Need to Change My Mortgage to Rent My House?
Not always. For temporary letting, your lender may offer consent to let. Permanent letting may require a buy-to-let mortgage.
Can I Rent My House for One Year and Then Move Back In?
You can plan to, but you cannot guarantee vacant possession exactly after one year. From May 2026, landlords normally need Ground 1 to recover a property for their own occupation, subject to the protected period and notice requirements.
Can I Rent Out My First Home and Buy Another?
Yes, subject to mortgage affordability, but keeping the first home can mean higher-rate SDLT applies when purchasing the second property in England or Northern Ireland.
Do I Pay Tax If I Rent Out My First Home?
Potentially. Rental profits are generally taxable, and different rules apply to mortgage finance costs. Separate property-income rates of 22%, 42% and 47% take effect from 6 April 2027.
Can I Rent Out My First Homes Scheme Property?
Generally for up to two years in aggregate, subject to notifying the local authority, complying with the mortgage and meeting the scheme’s conditions. Extensions may be possible in exceptional circumstances.
What Happens If I Rent My Property Without Mortgage Permission?
You may breach your mortgage terms. Depending on the lender, consequences can include higher interest, charges, restricted borrowing or more serious enforcement action.
