For most UK homeowners, the fixed-rate mortgage offers stability and predictability. However, fixed-rate terms—typically two, five, or ten years—do not last forever. When the promotional period ends, your monthly payments will likely change significantly, potentially resulting in a steep increase in costs if you do not take proactive steps.

TL;DR: When your fixed-rate mortgage ends, you automatically move onto your lender’s Standard Variable Rate (SVR), which is usually much higher than your previous fixed rate. To avoid substantially higher monthly repayments, you must secure a new mortgage product deal—either through a product transfer with your current lender or by remortgaging to a new provider—ideally starting the process 3 to 6 months before the fixed term expires.

What Happens When My Fixed-Rate Mortgage Ends? Understanding Your Next Steps

A fixed-rate mortgage is a deal where your interest rate remains constant for a set period. This provides financial certainty, protecting you from interest rate fluctuations during that time. The crucial point many borrowers miss is that the fixed term expiry date is not the end of your mortgage debt, but rather the end of that specific interest rate agreement.

Understanding what happens when your fixed-rate mortgage ends is vital for maintaining control over your finances. If you do nothing, you will automatically transition to your lender’s Standard Variable Rate (SVR). This shift means your payments are no longer protected by the stable rate you enjoyed.

The Automatic Shift to the Standard Variable Rate (SVR)

The Standard Variable Rate (SVR) is the default interest rate used by your lender once your introductory deal (whether fixed, tracker, or discounted) comes to an end. Every lender sets its own SVR, and critically, it is subject to change at any time, often fluctuating based on the Bank of England Base Rate, though not necessarily following it directly or immediately.

The gap between a competitive fixed rate and your lender’s SVR is often substantial. For example, if you were paying 4% on a fixed deal, your lender’s SVR might be 8% or more. This jump can add hundreds, sometimes thousands, of pounds to your monthly mortgage bill.

Why the SVR is a Temporary Solution

While the SVR offers flexibility—there are typically no Early Repayment Charges (ERCs), meaning you can leave at any time without penalty—it is rarely a financially sound long-term solution. Your primary goal upon the expiry of your fixed term should be to secure a new competitive rate to keep your borrowing costs down. This process involves choosing between two main pathways: a product transfer or remortgaging.

Option 1: Product Transfer with Your Current Lender

A product transfer is the simplest route. It involves moving from your expired fixed-rate product directly onto a new deal offered by your existing mortgage provider. This option is appealing due to its speed and simplicity.

Benefits of a Product Transfer:

• Speed: Often quicker than remortgaging, sometimes taking just a few days to complete.
• Minimal Underwriting: If your financial circumstances haven’t changed drastically and you haven’t defaulted on payments, the lender often requires less stringent checks (sometimes waiving affordability checks entirely, though this is not guaranteed).
• Reduced Costs: You generally avoid solicitor fees and comprehensive valuation costs, although there may still be a product arrangement fee.
• No Legal Work: Since you are not changing lenders, there are no complex legal or conveyancing requirements.

The main drawback is that your existing lender may not offer the most competitive rates available on the wider market. If you have significant equity in your property or your financial position has improved, remortgaging might unlock better savings.

Option 2: Remortgaging to a New Lender

Remortgaging involves switching your mortgage debt from your current provider to a completely new one. This path is often chosen when a competitor offers a significantly better interest rate or if you wish to borrow more money (further advance).

When you remortgage, the new lender will treat the application like a brand new mortgage, meaning you must pass all current affordability checks, stress tests, and credit assessments.

Key Factors When Remortgaging

When considering a remortgage, two primary factors influence the rates you are offered:

1. Loan-to-Value (LTV): This is the ratio of your mortgage debt compared to the current value of your property. If your property has increased in value, your LTV ratio will decrease, potentially moving you into a lower risk bracket and securing a cheaper rate.
2. Affordability and Credit Score: Lenders assess your income, outgoings, and credit history rigorously. A good credit history is essential for accessing the most desirable products.

Before any lender offers you a new deal, they will assess your current financial standing, including your income, existing debt, and credit history. Understanding your credit score is crucial, as lenders reserve their best rates for borrowers with excellent credit profiles.

The Critical Timeline: When to Start the Process

If you wait until the fixed rate has expired, you will likely spend at least a few weeks paying the expensive SVR while your new deal is being processed. To avoid this financial hit, you should start planning well in advance.

Three to Six Months Before Expiry

Most experts recommend starting your research and contacting a mortgage broker or financial adviser approximately six months before your fixed term is due to expire. Many lenders will allow you to secure a rate up to six months in advance, locking in today’s best deal while you wait for your current product to end.

By three months before the expiry date, you should have engaged a broker, gathered necessary documentation (payslips, bank statements, identification), and submitted an application for either a product transfer or a remortgage.

• 180 Days Out: Start shopping around. Determine your current LTV and check your credit report.
• 90 Days Out: Submit the application. If remortgaging, instruct solicitors.
• 30 Days Out: Finalise details. The new lender sends the formal offer.
• Expiry Date: The new deal completes, ensuring you transition immediately from the old fixed rate to the new one, bypassing the SVR entirely.

Understanding the Costs Involved in Switching Deals

While moving to a new rate saves money in the long term, there are upfront costs associated with both product transfers and remortgaging.

Costs Common to Both Deals

Arrangement Fee/Product Fee: Most new mortgage products carry a fee, typically ranging from £999 to £1,499. Sometimes, lenders offer “fee-free” deals, but these usually come with a slightly higher interest rate. You can usually choose to add this fee to the loan, but this means you pay interest on it.

Additional Remortgaging Costs

If you remortgage to a new provider, you will typically incur further expenses:

• Valuation Fee: The new lender will require a valuation of your property to confirm the LTV. Some products offer a free valuation incentive.
• Legal Fees (Conveyancing): A solicitor is required to handle the legal transfer of the charge over the property from the old lender to the new one. These fees can vary significantly.
• Exit/Redemption Fee: Your current lender may charge a small administrative fee (usually £50–£150) to close your existing mortgage account.

Always calculate the total cost of the deal—including interest and all associated fees—to ensure the lowest headline rate truly offers the best value for your circumstances.

Risk and Compliance Note

Taking on any mortgage debt carries inherent risks. While securing a new fixed rate protects you from immediate rate rises, if you choose a variable rate product (like a tracker mortgage), your payments could increase. Regardless of the product chosen, maintaining consistent repayments is essential.

Failure to meet the required monthly repayments on any mortgage product can lead to severe consequences, including default notices, damage to your credit rating, and potential legal action from your lender. Ultimately, your property may be at risk if repayments are not made. This could lead to repossession, increased interest rates, and additional charges applied to your debt.

People also asked

Can I switch my fixed-rate mortgage before the term ends?

You can switch before your term ends, but you will almost certainly incur an Early Repayment Charge (ERC). These charges are usually calculated as a percentage of the outstanding loan amount (e.g., 2% to 5%) and can be very expensive. Switching early is typically only beneficial if the interest savings outweigh the ERC.

What is a Mortgage Broker and should I use one?

A mortgage broker is an independent professional who can assess your financial situation and recommend products from various lenders across the market. Using a broker is highly advisable as they have access to deals you might not find yourself and can navigate the complexities of affordability criteria, potentially saving you significant time and money.

Will I need a solicitor if I opt for a product transfer?

No, generally, you do not need a solicitor or legal assistance if you complete a product transfer with your current lender, as the title deeds and the legal charge over the property remain unchanged. Solicitors are only required if you are remortgaging and changing lenders.

What happens if I cannot afford the new mortgage rate?

If affordability is a concern, it is crucial to speak to your current lender as soon as possible. They have a duty to treat customers fairly and may offer solutions such as interest-only payments for a short period or the option to extend the overall mortgage term to reduce monthly payments, though this increases the total amount of interest paid over the long term.

What is a ‘porting’ a mortgage?

Porting a mortgage means taking your existing mortgage deal (including the interest rate) with you when you move property. This option can be complex, as you still need to meet the lender’s current affordability and criteria for the new property, and you may have to take out a separate ‘top-up’ loan at a different rate if you need to borrow more.

Final Thoughts on Managing Your Mortgage Expiry

The expiry of a fixed-rate mortgage is not a moment for panic, but a clear signal that action is required. By treating the process proactively, starting your search well in advance, and comparing both product transfers and remortgaging options thoroughly, you can transition smoothly onto a new competitive rate, ensuring your property remains an asset and your monthly payments stay manageable.
