Mortgage Prisoners

Many UK homeowners remain on high mortgage rates because they can’t move to a better deal, but there are routes to improve your position. In this guide, we set out what a mortgage prisoner is, the reasons it happens, the options available today, and how specialist brokers can help you reach the right solution.

What is a mortgage prisoner?

A mortgage prisoner is a borrower who cannot switch to a new mortgage deal. This typically happens because the current lender no longer lends, the borrower’s affordability no longer meets today’s criteria, or their circumstances have changed since the home loan was first taken out.

Many mortgage prisoners end up on the lender’s Standard Variable Rate (SVR), which is often far higher than typical rates. It’s a challenging position to be in: even if you can manage the higher monthly repayments, it can feel unfair that so many options are closed for reasons beyond your control.

Types of mortgage prisoners

Mortgage prisoners usually fall into two main groups:

• Closed-book or inactive lenders: Borrowers whose lenders have stopped offering new mortgages.
• Borrowers who no longer meet affordability rules: After the 2014 Mortgage Market Review (MMR), lenders tightened affordability checks. Some customers who qualified before 2014 can’t pass today’s stress tests, even with years of on-time payments.

How homeowners become mortgage prisoners

Here is a breakdown of the main reasons people become mortgage prisoners.

Your lender is inactive or your mortgage was sold

Following the financial crisis, some mortgage books were sold to firms that don’t offer new products. If your lender has no fixed rates or alternative deals to switch to, you can be left on the Standard Variable Rate (SVR) with no internal options.

You don’t pass today’s affordability assessments

A strong payment history doesn’t always mean you’ll meet current checks. Since the 2014 Mortgage Market Review (MMR), lenders apply tighter rules and higher stress tests. You might now fail due to factors such as:

• tougher interest-rate stress testing;

• a lower income than when you first applied;

• new debts or ongoing financial commitments;

• moving from employed to self-employed;

• age-based lending limits;

• changes to the property (e.g. cladding) or a revised valuation;

• reliance on expired schemes such as Help to Buy.

High loan-to-value (LTV)

If your property value has fallen or you started with a high LTV and built little equity, you may struggle to qualify for competitive remortgage rates. A sharp drop in valuation can quickly leave you with minimal or even negative equity, restricting your ability to switch.

Interest-only with no repayment plan

Legacy interest-only loans are a common issue. Many borrowers cannot move to a new deal because lenders now require a clear, credible repayment strategy. If you must switch to a capital-and-interest repayment mortgage, your household budget might not support the higher monthly repayments.

Your mortgage options

Being a mortgage prisoner limits your options, but there are possible routes out. The right path depends on who owns your mortgage and your wider finances.

Switching with an active lender

If your mortgage sits with an active lender (one that still offers new products, even if pricing is higher), the first step is a product transfer. Because you remain with the same lender, affordability checks are often lighter. This is usually the simplest and fastest way to move off the SVR.

The ‘Green Channel’ (FCA switch)

If you’re with a closed-book or inactive lender, the FCA’s Modified Affordability Assessment (MAA)—often called the ‘Green Channel’—can help certain borrowers switch to participating active lenders. Under this route, lenders may use a streamlined affordability test for eligible mortgage prisoners who meet strict criteria. Access typically requires specialist advice, as only a limited number of lenders take part and each has precise rules.

Specialist lenders and adverse credit

Where credit issues or non-standard income make standard MMR rules hard to pass, specialist lenders can offer more flexibility. Many use manual underwriting, allowing a tailored view of your situation that may open up options a mainstream lender would decline.

Tips for improving your situation

One of the toughest parts of being a mortgage prisoner is how little control you may feel you have. That said, these practical steps can help speed things up and improve your chances of moving to a better deal:

• Increase your income or salary where possible

• Improve your credit score and correct any errors on your file

• Overpay your current mortgage to build equity

• Consider downsizing to a lower-priced property

• Reduce your debts and cut discretionary spending

• Work with a specialist broker experienced in helping mortgage prisoners
