How it works
Select your current lender
Tell us who your mortgage is with and a few basics: your balance, property value, repayment type and remaining term. That’s all we need to get started – no credit checks, no commitments, and nothing you wouldn’t already know off the top of your head. We currently support 20 mainstream lenders.
See your rates and how they compare
We show you the rates available through your existing lender, alongside the three lowest rates available elsewhere – all monitored in real time as the market moves, so you always have an accurate picture before making any decisions. When you’re ready, simply set an alert against your chosen rate.
We secure and manage your rate
Once you’re inside your lender’s switch window, we secure your chosen rate on your behalf – and keep watching. If that exact rate drops, we resecure it at the lower level – and we’ll do this as many times as needed before your switch completes. Lenders won’t do this. Lots of brokers won’t either. We do.
Who we’ve worked with
A few common questions
How does the rate securing and monitoring process actually work?
Once you’ve set an alert against your chosen rate, we get in touch to confirm your details and go ahead. As soon as you’re inside your lender’s switch window, we secure that rate on your behalf – we’re an FCA regulated broker and have been arranging mortgages for the best part of a decade.
Once secured, that rate is locked in – so if your lender increases their pricing after that point, you’re not affected. You keep the rate you secured, regardless of what happens in the market.
From there, we monitor continuously right up to your renewal date. If the same rate drops, we resecure it at the lower level – and we’ll do this as many times as needed. Your lender won’t tell you when this happens. Lots of brokers won’t either. You simply end up on the lowest rate your lender offered during the entire run-up to your renewal – without having to chase anyone or lift a finger.
What if I’ve already secured a rate and can’t see it in the app?
Because our rates are live, it’s possible that the rate you secured – whether directly with your lender or through another broker – was available at a lower level than what’s showing now. That’s actually a good sign: it means you secured at the right time.
For situations like this, we have a ‘set alternative rate’ feature. Rather than monitoring from the current rate downwards, you simply enter the rate you’ve already secured and we’ll notify you only if it drops below that level. If it does, we can resecure it for you at the lower rate – the same process as normal, just with your existing secured rate as the starting point.
So even if you can’t see your exact rate in the app, you’re still fully covered.
How often do lenders reprice their rates?
There’s no fixed schedule – lenders can change rates at any time, sometimes overnight and with very little notice. In volatile periods, deals can appear and disappear within a single day.
RateSwitch monitors your lender’s rates continuously, so when something changes we’re on it immediately. If a lower equivalent appears before your new rate starts, we resecure it for you automatically – no action needed on your part.
What causes lenders to reprice their mortgage rates?
Lenders price their fixed-rate deals around something called swap rates – market indicators of where interest rates are expected to go. When these move, mortgage pricing tends to follow quickly, sometimes within hours.
This is why rates can rise sharply even when the Bank of England hasn’t changed the base rate.
My rate isn’t up for renewal for a while – is it too soon to get started?
Not at all – in fact, the earlier you set up an alert, the better.
Every lender has a switch window: the period before your renewal date during which you’re allowed to secure a new rate. As soon as you’re inside that window, RateSwitch can start monitoring and secure a rate on your behalf. Setting up an alert now means we notify you the moment your window opens.
It’s also worth knowing that switch windows can change. Most lenders currently operate a three to four month window, but this has shifted before. During the mortgage market turbulence of 2023, six month windows became standard almost overnight. If lenders extend their windows again – which is possible given current market conditions – you’ll benefit automatically, because we’ll notify you as soon as you’re eligible.
Why do you focus on my existing lender – and what if a better rate exists elsewhere?
Switching to a new deal with your current lender is usually the fastest, simplest and lowest-risk option. There’s no credit check, no affordability assessment and no paperwork – and you can secure a rate months before your renewal date.
That said, we show how your lender’s rates compare to the three lowest rates available elsewhere – so you always have the full picture. If the difference is significant and you’d like us to arrange a full remortgage to a new lender, we can do that too, also free of charge.
When we do this, we always secure a rate with your existing lender at the same time and keep monitoring both in parallel – including the rate we’ve secured with the new lender. Both are tracked continuously using Mortgage Metrics, the software platform that powers RateSwitch. If your current lender’s rate drops enough during the process to become the better deal, we’ll let you know. Either way, you’ll know you’ve ended up on the best rate available to you.
Couldn’t I just do this directly with my lender – or a different mortgage broker?
You can – but the difference is what happens after the rate is secured. If you go direct, or use a broker, you’re typically relying on them to spot and act on any rate drops. Unless monitoring is explicitly agreed upfront, it’s unlikely to happen consistently.
RateSwitch manages this automatically, resecuring lower rates as they appear, without you having to chase anyone or lift a finger. If you value your time as much as your money, it’s a straightforward choice. And if you’re already in the process of arranging things directly or through another broker, you’re still welcome to use RateSwitch – though we’d always prefer to handle the switch for you, so nothing gets missed.
Why do you need my email address and phone number?
We collect both so we can reach you promptly when it matters. Rate movements can be swift – so we send alerts by both email and WhatsApp to make sure nothing slips by unnoticed. We’ll also be in touch to confirm your details before we go ahead and secure anything on your behalf.
