Why You Should Remortgage Before Your Fixed Rate Ends
The single biggest reason to remortgage before your fixed rate ends is to avoid your lender's standard variable rate. When your fixed-rate period expires, your mortgage does not simply stop. Instead, it automatically rolls onto the SVR, which is the default rate your lender charges when you are not on a specific deal.
SVRs in the UK are typically between 6% and 8%, although they vary between lenders and can change at any time. Compared to the competitive fixed rates available on the market, which might be 2% to 3% lower, the difference can add hundreds of pounds to your monthly payments.
To put this into perspective, on a 200,000 pound mortgage with 20 years remaining, the difference between a 4% fixed rate and a 6.5% SVR is approximately 275 pounds per month. That is over 3,300 pounds per year in additional payments for the same mortgage, with none of the extra money going towards paying off your loan more quickly.
Beyond the immediate cost, there are other compelling reasons to plan your remortgage in advance:
- Rate security - By locking in a new rate before your deal ends, you know exactly what your payments will be, allowing you to budget with confidence
- Best rate selection - Starting early gives you time to compare deals properly, rather than rushing into a decision under time pressure
- Seamless transition - A well-timed remortgage means your new deal starts on the same day your old one expires, with no gap on the SVR
- Market protection - If interest rates are rising, securing a rate early protects you against further increases
The financial case for acting early is clear. Every month you spend on the SVR unnecessarily is money that could be in your pocket or being used to reduce your mortgage balance.
When to Start the Remortgage Process
The ideal time to start thinking about your next mortgage deal is around six months before your current fixed rate expires. This timeline gives you enough space to research the market, compare deals, submit an application, and complete the legal work without any rush.
Here is a suggested timeline for remortgaging before your fixed rate ends:
Six months before your deal ends: Begin researching the market and speaking to mortgage brokers. Most UK lenders will allow you to apply for a new rate up to six months before your current deal expires, and they will hold that rate for you until your switch date. This means you can lock in a competitive rate now and benefit from it as soon as your current deal ends.
Four to five months before: Finalise your choice of deal and submit your application. Gather all necessary documentation, including proof of income, bank statements, identification, and details of your current mortgage. Having everything ready speeds up the process considerably.
Two to three months before: The lender processes your application, carries out a valuation, and issues a mortgage offer. Your solicitor handles the legal work, including property searches and liaising with your current lender for a redemption statement.
One month before: Everything should be in place for a smooth completion on or around the date your current deal expires. Your solicitor will coordinate with both lenders to ensure the transition happens seamlessly.
If you are already within three months of your deal ending and have not started the process, do not panic, but act quickly. A broker can often fast-track the process, and some product transfers with your existing lender can be completed in a matter of days.
The key point is that starting early gives you options and control. Leaving it late introduces pressure and the risk of costly gaps on the SVR.
How Rate Locks Work and Why They Matter
One of the most valuable features available to homeowners planning a remortgage is the ability to lock in a mortgage rate in advance. A rate lock, sometimes called a rate reservation or rate hold, allows you to secure a specific interest rate today and have it applied to your mortgage when your current deal expires, even if rates change in the interim.
Most UK lenders offer rate locks of between three and six months, with some offering holds of up to nine months or even longer. This means you can apply for a new mortgage well before your current deal ends and know exactly what rate you will be paying.
How a rate lock protects you:
- If interest rates rise between the time you lock in and the time your new deal starts, you are protected because your rate is already secured
- If interest rates fall during the same period, some lenders offer a rate promise that allows you to switch to the lower rate. This gives you the best of both worlds, though not all lenders offer this feature
- The rate lock gives you certainty over your future payments, which makes financial planning much easier
To take advantage of a rate lock, you need to submit a full mortgage application. The lender will assess your affordability, carry out a credit check, and arrange a valuation of your property. Once the application is approved and the mortgage offer is issued, the rate is locked in for the specified period.
If the rate lock period expires before your deal ends, you may need to reapply or extend the lock. Check with your lender or broker about the specific terms that apply. In most cases, a six-month lock is more than sufficient to cover the gap between applying and your deal expiring.
Rate locks are available on both full remortgages with a new lender and product transfers with your existing lender. If your current lender offers competitive rates, a product transfer with a rate lock can be particularly straightforward, as the process is typically simpler and faster than switching lenders.
