Why Mortgage Consent Matters

Renting out your home can be a smart financial move, but only if your mortgage allows it. Many landlords don't realise that letting under the wrong mortgage type can breach terms and lead to penalties. Before listing your property, it's crucial to understand the rules of your existing loan.

Already on a Buy-to-Let Mortgage?

Good news. If you already have a buy-to-let mortgage, you’re usually clear to proceed but always double-check the small print. Some lenders include clauses about tenant types (e.g., no DSS or students) or lease term restrictions. Our lettings team can help you review your agreement for peace of mind.

Letting on a Residential Mortgage

Residential mortgages are for owner-occupiers, not landlords. If you're planning to leave but still have a residential loan, you'll need permission. Failing to disclose it may breach your terms and invalidate your insurance. Always contact your lender to explain your plans and request approval first.

The Three Likely Outcomes

When you speak to your lender, one of three things usually happens:

1. They grant temporary permission known as 'consent to let'.
2. They ask you to switch to a buy-to-let mortgage.
3. If they say no, you may need to remortgage with a different lender.

What is Consent to Let?

This is a short-term agreement from your lender allowing you to rent out your property while still on a residential mortgage. It's often granted for 6–12 months and may include a fee or a higher interest rate. Consent to let is ideal for temporary scenarios, such as moving abroad or relocating for work.

When to Switch to a Buy-to-Let Mortgage

Planning to let long term? You'll likely need to switch to a buy-to-let product. These mortgages are designed for rental income, often requiring you to demonstrate that the expected rent covers 125–145% of the repayments. Our team can assist by providing rental valuations to support your mortgage application.

Don’t Forget Your Lease

If you own a leasehold property (like a flat), check your lease agreement. Many include restrictions on subletting or require formal permission from the freeholder. This may involve:

- Paying a consent fee

- Providing tenant details

- Signing a deed of covenant

Failure to comply with lease terms can lead to disputes or even legal action.
