This is a question we’re hearing more and more from clients, and understandably so. In a market where mortgage rates can change in a matter of days – or even hours – many buyers are wondering what happens if a better deal comes along after they’ve already applied. In most cases, the answer is: not automatically. But with the right support, you may still be able to benefit.
Why This Matters
The UK mortgage market has been particularly volatile in recent months. With lender pricing shifting rapidly and products being pulled at short notice, it’s never been more important to understand your options before and after your application is submitted.
Can I Switch to a Better Rate?
Some lenders do allow you to switch to a lower rate before you complete your mortgage, but some may not. Each lender has its own policy on this, and even where switches are permitted, they often come with conditions or require specific timing to trigger the change.
What is true is that if you do go direct to as lender, they will not contact you to tell you that rates have changed and a better rate may now be available. This is why working with an experienced mortgage adviser is so important.
How a Mortgage Broker Can Help
At Coreco, we keep a close eye on the market and act quickly when opportunities arise. Here’s how we help clients navigate this particular issue:
1. Real-Time Mortgage Market Monitoring
Lenders often adjust their rates in response to anticipated changes in the economy—not just official Bank of England announcements. We track these movements daily, so we can alert clients and act swiftly if a better product becomes available.
2. Understanding Lender Policies
We know which lenders allow product switches before completion and what the criteria are. We manage the process on your behalf—liaising with the lender, handling the paperwork, and ensuring any changes are processed efficiently.
3. Avoiding Costly Delays
It might be tempting to wait and see if rates fall before committing, but this approach can be risky. The best deals are often short-lived. We help clients secure a competitive deal early, and where possible, make use of lender flexibility to switch if rates drop before completion.
4. Representative of Whole-of-Market Access
Unlike banks, which can only offer their own products, we search the whole market to find the mortgage that best fits your needs. That includes:
• Access to more competitive rates
• Products tailored to your goals and circumstances
• Ongoing advice to adapt to any changes in your plans or the wider market

If you’re in the process of buying a home or remortgaging, and you’re concerned about rate changes, the best step you can take is to speak with a professional adviser.
