Consent to let: can you rent out a house with a residential mortgage?

In England, consent to let is usually a mortgage-contract issue rather than a housing statute issue, but it still matters because letting without lender permission can put the borrower in breach. The same lender-permission point applies across the UK in broad terms, with specific England, England-and-Wales, and London exceptions noted below.

What is consent to let?

Consent to let has no statutory basis — the FCA Handbook’s own search for the phrase finds no results — and it is a lender’s contractual permission for a residential-mortgage borrower to rent out the home temporarily rather than switch immediately to a buy-to-let mortgage. NatWest defines consent to let mortgage permission this way: “Consent to Let means we give you permission to rent out your home temporarily.” That is why the phrase consent to let on a residential mortgage is not a separate legal status of the tenancy; it is the lender saying it will tolerate a use that the original owner-occupier mortgage may otherwise prohibit. A lender may attach a fee, a rate loading, a time limit, or a condition that you move to buy-to-let later. The important hard edge is that case law and lender practice treat consent as discretionary, not something the borrower can demand.

What is the difference between consent to let and a buy-to-let mortgage?

Consent to let keeps the existing residential mortgage in place for a temporary letting, while a buy-to-let mortgage is a mortgage taken or switched onto because the property is intended to be let. MoneyHelper states the practical lender choice clearly: “Some lenders will grant you a 'consent to let' on your current deal, while others may insist on you switching to a buy-to-let mortgage.” The legal distinction is also visible in the regulated-activities rules: a buy-to-let mortgage contract includes a case where, at the time of purchase, the borrower intended the home to be occupied under a rental agreement and not occupied by the borrower or a related person. In consent to let vs buy to let terms, consent to let is usually a bridge for accidental or temporary landlords; buy-to-let is the long-term product designed and priced for rental use.

Can you rent out a property that has a residential mortgage?

You can rent out a property with a residential mortgage only if your lender permits it, because the duty to get consent comes from the mortgage contract rather than a freestanding statute. MoneyHelper gives the borrower-facing rule: “No matter how or why you've now become a landlord, you must tell your mortgage lender if you're going to let out a property that has an owner-occupier mortgage.” So the answer to can I get a residential mortgage and rent it out is no if the plan exists from the start; that is normally buy-to-let territory. If circumstances change later, can I rent my property if I have a residential mortgage becomes a lender-consent question. Can you sublet if you have a mortgage is the same mortgage-permission issue, though the tenancy terms, leasehold covenants, insurance and local licensing may add separate limits.

What counts as a valid reason for consent to let?

A valid reason for consent to let is whatever reason the lender’s own policy accepts, because no statute or FCA rule sets an approved list of reasons. The FCA Handbook treats consent to let as one possible mortgage variation, saying a variation might involve “consent to let the property,” but it does not prescribe when the lender must agree. In practice, accepted reasons often include work relocation, armed-forces or diplomatic posting, temporary inability to sell, moving in with a partner, or needing to rent while buying elsewhere. NatWest gives two typical examples: customers may need consent because they “move for work” or “find it hard to sell their home.” Those are examples, not universal rights. A lender can still refuse if the mortgage is too new, the account is in arrears, the loan-to-value is too high, or the proposed letting conflicts with its criteria.

Do you have to tell your mortgage lender if you rent out your house?

You do have to tell your mortgage lender if you rent out your house on an owner-occupier mortgage, because the mortgage conditions normally require it and market guidance says failure can invalidate the mortgage. MoneyHelper’s wording is direct: “No matter how or why you've now become a landlord, you must tell your mortgage lender if you're going to let out a property that has an owner-occupier mortgage.” The answer to do I have to tell my mortgage lender if I rent out my house is therefore yes, even though the obligation is contractual rather than a criminal-law rule. The right answer to what not to tell a lender is not to conceal the letting: you should not misstate occupation, rent, tenant status, or whether you have moved out. The lender may then grant consent, charge for it, decline it, or require a buy-to-let remortgage.

What happens if you let your property without consent to let?

Letting without consent to let is normally a mortgage-contract breach, not automatically a criminal offence, and the lender’s remedies can include a fee, a higher rate, demanding repayment, or repossession. AXA summarises the range: “The consequences can range from a penalty fee to your mortgage rates being raised, to demanding you pay back your loan immediately and repossessing your home if you can’t.” The same point answers what happens if I don’t change my mortgage to buy-to-let: the issue is whether the lender agreed to the letting, not the label alone. In England and Wales, if the lender later repossesses and the tenant was never binding on the lender, the court can protect that tenant briefly: it may “postpone the date for delivery of possession for a period not exceeding two months.” That postponement helps the tenant move; it does not cure the borrower’s mortgage breach.

How soon after taking out a mortgage can you get consent to let?

How soon you can get consent to let depends on the lender, with published minimums commonly around 6 to 12 months rather than any statutory waiting period. Halifax says: “Your mortgage must be active for at least six months to gain our agreement - unless you’re a member of the British Armed Forces, the Diplomatic Service or have tied accommodation.” The Co-operative Bank sets a longer starting point, saying: “The mortgage should have been in force for at least 12 months.” So can you get consent to let straight away is usually no, unless a lender’s policy has an exception or the borrower’s circumstances fall into a protected category such as forces posting or tied accommodation. The cleanest practical answer is to check the lender’s own conditions before letting, because the waiting period is a product rule, not a legal rule shared by all lenders.

How long does consent to let last?

Consent to let usually lasts for the period the lender grants, commonly 12 months, but published lender terms range from 12 months to 27 months and market guides often describe a maximum around 24 months. Halifax says that if it agrees, it will write to confirm permission “for 12 months.” The Co-operative Bank says: “If Consent to Let is granted, this is for a maximum period of 16 months.” HSBC publishes a longer limit, allowing consent to let “for up to 27 months.” That is why how long does a consent to let a mortgage last has no single statutory answer. Nationwide consent to let how long, NatWest consent to let and Santander consent to let must each be checked against that lender’s current policy, because duration is set by contract and can change between products.

Can consent to let be renewed, and how many times?

Consent to let can be renewed if the lender’s policy allows it, but there is no statutory right to renewal and no universal cap on how many times you can renew consent to let. Halifax gives an example of rolling review rather than a fixed one-off permission: “If we agree for you to rent your home, we’ll automatically do annual checks to see if you can continue for another 12 months.” Uswitch describes the wider market by saying that most agreements last up to 24 months, but “it may be possible to extend the consent to let period or pay an annual fee to maintain the agreement in the long term.” If your mortgage lender only gave one-year consent to let and it is about to expire, renewal depends on the lender’s criteria at that point. If the lender refuses, the choices are usually remortgage, sell, or negotiate.

Can a mortgage lender refuse consent to let?

A mortgage lender can refuse consent to let, because consent is discretionary unless the mortgage contract itself says otherwise. HomeOwners Alliance states the market position bluntly: “However, lenders do not have to agree to give consent to let and may impose a higher rate or fee.” LexisNexis, discussing residential owner-occupier mortgages, states that no implied obligation arises requiring the lender to act reasonably when withholding consent to a letting. That means a lender can refuse because the mortgage is new, the account is in arrears, the proposed tenancy is unsuitable, the loan-to-value is outside policy, the borrower wants indefinite letting, or the product does not permit consent at all. Nationwide permission to let refused is not a special legal category; it is the same problem under that lender’s criteria and the borrower’s mortgage terms.

What can you do if your lender refuses consent to let?

If your lender refuses consent to let, the practical options are to ask for a policy exception, switch to a buy-to-let mortgage, remortgage to another lender, sell, or keep occupying the property. HomeOwners Alliance gives the usual fallback: “If your lender doesn't agree to grant consent to let, then your other option is switching to a Buy to Let mortgage.” Paying the early repayment charge is therefore not always the only way out, but it may be the cost of leaving a fixed residential product if no port, product-transfer or internal buy-to-let route is available. If the need to rent is temporary, evidence helps: employer posting letters, armed-forces orders, sale listings, or tied-accommodation documents can make a discretionary exception more likely. If a tenant is already in place, the lender’s refusal does not itself end that tenancy.

If your lender will not renew consent to let, can you evict the tenant?

If your lender will not renew consent to let, that fact alone is not an automatic possession ground against the tenant; in England the relevant routes are usually remortgage, sale, or a statutory possession ground that actually fits. Ground 2 is about the mortgagee needing possession for sale: the lender must require possession “for the purpose of disposing of it with vacant possession in exercise of that power.” Since 1 May 2026, England also has a landlord-intends-to-sell ground: Ground 1A applies where “the landlord who is seeking possession intends to sell” the freehold or leasehold interest, subject to the statutory conditions and timing. A lapsed one-year consent to let therefore does not by itself evict an indefinite periodic tenant. The landlord normally has to regularise the mortgage, sell using the correct ground, or face the lender’s remedies.

Which lenders grant consent to let, and on what terms?

Lenders that publish consent-to-let or permission-to-let terms include NatWest, Halifax, HSBC, Skipton, Barclays and The Co-operative Bank, but their conditions differ on fees, duration, rate loading and minimum time on mortgage. NatWest says consent means permission to rent the home temporarily and lists “a one‑off fee of £120.” Halifax says it adds “0.5% on top of your existing interest rate” and usually requires six months on the mortgage. HSBC says customers can apply for consent to let “for up to 27 months,” while The Co-operative Bank says consent is for a maximum of 16 months and the mortgage should usually have been in force at least 12 months. Santander consent to let and NatWest consent to let should be checked on the lender’s own current pages before acting, because these are product policies, not statutory entitlements.

Do you need consent to let to take in a lodger?

You usually do not need formal consent to let for a lodger in the same way as moving out and letting the whole property, but you should still check and tell the lender because mortgage conditions may require notice or approval. Manor Mortgages Direct summarises the broker view: “That usually means no formal consent to let is needed, however most mortgage conditions say you should check the terms and inform the lender first.” The reason is that consent to let is normally aimed at renting out the home while the borrower lives elsewhere, whereas a lodger occupies a room under the resident owner’s continuing occupation. Some insurer and lender pages use looser language and may still tell borrowers to seek consent for a lodger, so the safe distinction is this: a lodger may not be a consent-to-let case, but it is still a mortgage-disclosure and insurance-disclosure issue.

Who has to sign an occupier's consent form, and why?

An occupier’s consent form is usually signed by an adult occupier who lives at the property but is not a borrower or legal owner, because the lender wants that person to postpone any occupation rights behind the mortgage. In England and Wales, the legal risk is that an interest belonging to a person in actual occupation can override registered title; the Land Registration Act describes this as “An interest belonging at the time of the disposition to a person in actual occupation.” Homes England’s Help to Build guide gives a practical version: “Anyone aged 17 or over, who lives with you but is not applying for an equity loan with you, must sign an occupier's consent form to confirm they do not have an interest in your home.” That explains why a lodger, partner or adult child may be asked to sign before completion or remortgage.

Can you put your house on Airbnb if you have a residential mortgage?

You can put your house on Airbnb with a residential mortgage only if your mortgage terms and lender policy allow short letting, and in Greater London you must also stay within the 90-night planning rule unless you have planning permission. Uswitch notes that some lenders treat short lets differently: “Some lenders won't need you to apply for a consent to let if you're only planning to let your property through Airbnb or similar services.” That is lender-specific, not a legal permission you can assume. The London statutory rule is separate: the Deregulation Act 2015 says use as temporary sleeping accommodation in Greater London is not a material change of use only if its conditions are met, which is the basis of the 90-night annual limit. Outside that planning rule, Airbnb is still constrained by mortgage terms, leases, insurance, licensing, tax and safety duties.

Can you get a second residential mortgage if you already have consent to let?

You can get a second residential mortgage while you already have consent to let, but approval depends on affordability, lender policy and whether the new property will genuinely be your home. Strive Mortgages states the legal starting point: “There is no legal restriction in the UK that limits you to one residential mortgage.” The hard part is underwriting: the first mortgage, rent, void risk and consent-to-let expiry may still affect affordability, and lenders differ on whether they treat the let property as self-funding. If the second home is in or near London or Manchester, the location matters mainly through price, income multiples and deposit size, not a special consent-to-let rule. Landlords often quote the old 3% stamp duty surcharge, but the current England and Northern Ireland second-home SDLT surcharge is 5%: gov.uk says, “You usually pay 5% on top of these rates if you own another residential property.”
