Reserve and Improve: Why Remortgaging Homeowners Should Start 6 to 9 Months Before Their Deal Ends
When it comes to remortgaging, one of the biggest mistakes homeowners make is waiting until the final few weeks of their current mortgage deal before exploring their options. In today’s market, where mortgage rates can change quickly, a better approach is to“Reserve and Improve”.
The strategy is simple: secure a new mortgage deal with a new lender as early as possible, then continue monitoring the market right up to completion.
What Is Reserve and Improve?
Reserve and Improve means applying for a remortgage with a new lender well in advance of your current deal ending, typically six months ahead and in some cases up to nine months before completion.
By securing a rate early, you create a safety net. If rates rise, your reserved deal is protected. If rates fall, your broker can review the market and potentially move you to a better deal before completion.
Rather than trying to predict what the market will do, you’re giving yourself options.
Why Start 6 to 9 Months Early?
Many lenders allow remortgage applications significantly earlier than most homeowners realise.
Starting early provides:
- Access to today’s rates before they disappear.
- More time to prepare paperwork and documentation.
- Greater lender choice.
- Less pressure as your current deal approaches expiry.
- Protection from unexpected market movements.
Most importantly, it removes the need to gamble on what mortgage rates might be doing in six months’ time.
Mortgage Rates Can Change Quickly
Over the past few years, mortgage rates have regularly moved in response to inflation data, Bank of England expectations, swap rate movements and global events.

By reserving a rate early, you are effectively locking in an insurance policy against future increases.
The Best Part? You Can Still Improve the Deal
Many borrowers assume that once they have submitted an application, they are committed to that mortgage rate.
In reality, if your chosen lender launches a better product before completion, or if a more suitable option becomes available elsewhere, your broker may be able to review and improve your recommendation.
This means you can benefit from both certainty and flexibility.
Scenario 1: Rates Rise
Your reserved deal remains in place and protects you from market increases.
Scenario 2: Rates Fall
Your broker reviews the market and, where possible, helps you secure a better deal.
Scenario 3: Nothing Changes
You still have peace of mind knowing your remortgage has been arranged well in advance.
Why Waiting Can Be Risky
Homeowners who delay until the last minute have fewer options.
If rates increase just before their current deal expires, they may have no choice but to accept a higher monthly payment. They also have less time to deal with underwriting requirements, valuation issues or changes in personal circumstances.
Starting early keeps you in control rather than reacting to the market.
Who Should Consider This Approach?
Reserve and Improve is ideal for:
- Anyone whose mortgage deal ends within the next 6 to 9 months.
- Homeowners concerned about future rate rises.
- Borrowers who want certainty over future payments.
- People who want to secure today’s rates without losing the opportunity to benefit from future improvements.
Final Thoughts
A remortgage shouldn’t start three weeks before your deal ends. The most proactive borrowers begin planning six to nine months ahead, giving themselves the widest range of options and the greatest protection against market uncertainty.
The Reserve and Improve approach is straightforward: secure a new deal early with a new lender, keep monitoring the market, and improve the deal if opportunities arise. If rates rise, you’re protected. If rates fall, you may still be able to take advantage.
In an uncertain mortgage market, that’s a strategy that simply makes sense.
