Why we built this
RateSwitch was originally launched in April 2016 with a simple idea: make it easier for existing mortgage customers to see the rates available to them. At the time, comparison websites like Go Compare and MoneySuperMarket only showed rates for new customers – so the deals available to people already on a lender’s books were largely invisible. We built a comparison tool to change that.
It was an industry first. But over the next few years, the big players caught up and started including this data within their own platforms. There was no competing with marketing budgets running into the tens of millions, so we moved on.
In February 2020 we launched Accelerate My Mortgage – a cashback engine that automatically paid everyday retail purchases off your mortgage as overpayments. Another industry first. And then, almost immediately, a global pandemic arrived and changed everything.
COVID briefly helped – the high streets closed and the whole country was shopping online. But as life returned to normal, the opportunity had passed. Retailers no longer needed cashback to drive online sales. It had simply become how people shopped.
Then came Liz Truss’ mini-budget in September 2022. Mortgage rates soared overnight, and homeowners were left scrambling. We saw a clear problem that needed solving: lenders weren’t telling their customers when rates dropped, and most brokers weren’t monitoring continuously either. So we built Mortgage Metrics – a software platform that does exactly that, used by brokers across the country to ensure their clients never miss a rate drop between application and completion.
In early 2025, we integrated that same technology directly into RateSwitch – making it available to homeowners for the first time, free of charge and with no strings attached.
Then, in March 2026, history repeated itself. The escalating conflict in the Middle East sent swap rates sharply higher almost overnight. Within eleven days, the average two-year fixed mortgage rate jumped by 0.44 percentage points – hundreds of mortgage deals were pulled from the market, and every fixed rate below 4% disappeared.
We relaunched RateSwitch as a free alert service in direct response. If your rate drops before your switch date, you’ll know about it immediately – whatever broker you use, whatever lender you’re with. That’s all we’re here to do.

FAQS
Can I switch early?
Yes — in many cases you can. Each lender has its own switch window, typically allowing you to secure a new deal several weeks or months before your current rate ends. The exact timing depends on your lender and product, which is why switch periods can vary.
Do I have to take legal advice?
No. Product transfers typically don’t require legal work or a property valuation.
Will there be a credit check?
Product transfer checks are usually lighter than a full remortgage. The exact checks can vary and are set by the lender.
What if rates change after I’ve secured?
If they rise, you’re locked in. If they fall before your switch date, we’ll alert you so you can amend your choice if available.
