What is Consent to Let and when do I need one?

Full answer

Consent to Let bridges the gap between a standard residential mortgage (designed for owner-occupation) and a full buy-to-let mortgage (designed for rental property), and understanding when it applies avoids inadvertently breaching your mortgage terms. **Why residential mortgages restrict letting** Standard residential mortgages are priced and underwritten on the basis that the borrower will live in the property as their main home -- lenders charge different rates, apply different risk assessments, and sometimes have different regulatory treatment for buy-to-let lending, since rental properties carry different risks (such as void periods, tenant default, and different types of legal obligations) compared with an owner-occupied home. Letting out a property on a standard residential mortgage without permission breaches the mortgage terms, even if mortgage payments continue to be made on time. **When Consent to Let is typically used** Common scenarios include: moving in with a partner and renting out your own former home rather than selling it immediately; relocating for work on a temporary basis and wanting to let your home while away rather than selling; struggling to sell a property in a slow market and needing to let it out to cover the mortgage while continuing to try to sell; or inheriting a property with an existing residential mortgage that you want to rent out rather than immediately selling or moving into. **How to obtain it and typical conditions** You apply directly to your existing mortgage lender (rather than needing to remortgage to a different product or lender), and if approved, the lender typically grants permission for a limited period (commonly 6-12 months, sometimes renewable) rather than indefinitely, may increase your interest rate slightly (reflecting the higher risk of a let property) or add a specific fee, and will usually require you to use a standard Assured Shorthold Tenancy agreement and comply with normal landlord obligations (deposit protection, gas safety checks, an EPC, and so on) despite the mortgage remaining technically residential rather than buy-to-let. **What happens if you let without consent** Letting a residential-mortgaged property without obtaining Consent to Let (or without informing the lender at all) is a breach of your mortgage contract -- if discovered, the lender could, in the most serious cases, demand immediate repayment of the full mortgage, though in practice many lenders will instead offer to formally regularise the situation (either granting retrospective consent, requiring a switch to a buy-to-let product, or requiring the letting to stop) rather than immediately calling in the loan, particularly where payments have continued to be made without issue. Insurance is also a serious separate risk -- if your buildings/contents insurance was arranged on the basis of owner-occupation and you have not informed the insurer of the change to a rented property, a claim could be refused entirely if something goes wrong. **Why Consent to Let is usually temporary, not permanent** Because Consent to Let is designed as a short-term accommodation rather than a permanent solution, lenders generally expect the borrower to eventually either move back in, sell the property, or switch to a proper buy-to-let mortgage if the letting arrangement is intended to continue long-term -- relying on repeatedly renewed Consent to Let indefinitely, rather than transitioning to an appropriate buy-to-let product, can eventually be refused by the lender. **Worked example** A homeowner is relocated by their employer to a different city for an 18-month secondment and wants to rent out their home rather than sell it, planning to move back afterwards. They apply to their existing residential mortgage lender for Consent to Let, which is granted for 12 months (with a small interest rate increase and a requirement to use a standard AST tenancy agreement), renewable for a further 6 months to cover the full secondment period. They also update their buildings insurance to a landlord policy, since their previous owner-occupier policy would not have covered them once the property was let out. **Practical tip** Always contact your existing lender BEFORE letting out a residential-mortgaged property, rather than letting it first and hoping the lender does not notice, since being upfront and transparent generally leads to a straightforward, cooperative process, while being discovered letting without consent can create much more serious problems, including potential mortgage default and voided insurance.
