Let’s be honest – mortgages aren’t exactly thrilling dinner party conversation. But here’s the thing: spending 20 minutes sorting out your mortgage rate could genuinely save you hundreds of pounds every single month. That’s holiday money. That’s the new car fund. That’s finally fixing that dodgy boiler.
So grab a cuppa, and let’s walk through this together. No jargon overload, promise.
Why Should You Even Bother Switching?
Right, here’s the deal. When your fixed rate ends (and they all do eventually), your lender doesn’t just find you another nice deal. Nope. They quietly shuffle you onto their Standard Variable Rate – the SVR. And SVRs are almost always rubbish.
We’re talking rates that can be 2-4% higher than what you were paying. On a £200,000 mortgage, that could mean an extra £300-400 a month just… disappearing. Not ideal, is it?
The Bank of England sets the base rate, and lenders adjust their deals accordingly. When you switch at the right time, you lock in a better rate before any increases hit.
Step 1: Find Out What You’re Actually Paying
Before you do anything, you need to know where you stand. Dig out your latest mortgage statement (it’s probably in that drawer you’ve been meaning to sort out) or log into your lender’s online portal.
What you’re looking for:
- Your current interest rate
- When your deal ends (mark it in your calendar!)
- How much you still owe
- Any early repayment charges
Most lenders let you switch to a new deal around 3-6 months before your current one expires. That’s your window. Miss it, and hello SVR.

Step 2: Shop Around (Yes, Really)
Your current lender will probably offer you a new deal. Great. But don’t just accept it without checking what else is out there. You wouldn’t buy the first car you saw, would you?
Here’s where it gets interesting. You’ve got two options:
Option A: Product Transfer (the easy route)
This is switching to a new rate with your current lender. It’s quick, usually fee-free, and they rarely credit check you again. The trade-off? You’re only seeing their rates, not the whole market.
Option B: Remortgage (the thorough route)
This means moving to a completely different lender. More paperwork, possibly some fees – but you get access to every deal out there. Sometimes the savings make it well worth the hassle.
Comparison sites like Which? can help you see the landscape, but honestly? A good mortgage broker sees deals you won’t find online.
Step 3: Have a Chat With Your Lender
Ring them up. Seriously. Ask what rates they can offer existing customers – sometimes there are loyalty deals that aren’t advertised anywhere.
Questions worth asking:
- “What’s the best rate you can offer me as an existing customer?”
- “Are there any fees if I switch now?”
- “Can I reserve a rate in advance?”
- “What happens if rates drop after I’ve locked in?”
Don’t be shy about mentioning you’re looking at other lenders too. A bit of healthy competition never hurt anyone.
Step 4: Check You Actually Qualify
Here’s where things can get a bit tricky. Lenders want to know you can afford what you’re borrowing. Fair enough, really.
They’ll look at:
- Your credit score – Check yours for free on Experian or Equifax before you apply
- Income and employment – Steady job? Self-employed? They want proof
- Outgoings and debts – Be honest about what you owe elsewhere
- Your property’s value – The loan-to-value ratio matters a lot
Good news: if you’re just doing a product transfer with your existing lender, they often skip the full affordability check since you’ve already got the mortgage. Makes life easier.
Step 5: Crunch the Numbers Properly
This bit’s crucial. A lower interest rate doesn’t always mean a cheaper mortgage overall. Annoying, but true.
Let’s say Lender A offers 4.2% with no fees. Lender B offers 3.9% but charges a £1,500 arrangement fee. Which is actually better? Depends how long you’re staying on that deal.
Things to factor in:
- Arrangement fees (sometimes added to the mortgage, which means you pay interest on them too)
- Valuation fees
- Legal fees for remortgages
- Early repayment charges if you leave before the deal ends
The Financial Conduct Authority has good guidance on what to look for in mortgage deals.
What About Remortgaging to a Different Provider?
Sometimes sticking with your current lender just isn’t the smartest move. Maybe their best rate is still pants, or maybe you want to borrow a bit extra for renovations.
Remortgaging to a new lender takes more effort – expect 4-8 weeks instead of a couple of weeks for a product transfer. You’ll need:
- A new valuation of your property
- Fresh affordability checks
- Solicitor involvement (some lenders cover this cost, though)
- More paperwork – payslips, bank statements, the lot
But here’s the thing: the savings can be substantial. We’re talking potentially thousands over a 2 or 5-year fix. And if your home has gone up in value since you bought it, your loan-to-value ratio improves – which often means access to better rates.
When remortgaging makes sense:
- Other lenders are offering significantly better rates
- You want to release equity from your home
- Your credit score has improved since you got your mortgage
- Your property value has increased (lower LTV = better rates)
- You want features your current lender doesn’t offer (like overpayment flexibility)
Worth getting a proper comparison done. It costs nothing to find out if you could do better.
Mistakes That’ll Cost You Money
Seen it all before. Don’t be that person who:
- Ignores the end date – Set a reminder 6 months before your deal expires
- Only looks at the interest rate – Fees matter just as much
- Doesn’t check their credit report – Surprises here are never good
- Accepts the first offer – Your lender’s initial offer is rarely their best
- Forgets about early repayment charges – Switching mid-deal can be expensive
Your Questions, Answered
How long does switching take?
Product transfers with your current lender? Often done in a week or two. Full remortgage to a new lender? Budget for 4-8 weeks, sometimes longer if there are complications.
Will it hurt my credit score?
A hard credit check (which happens when you formally apply) might dip your score slightly and temporarily. But paying less on your mortgage each month? That’s good for your finances long-term.
What if rates go down after I’ve locked in?
Some lenders let you switch to a better rate if one becomes available before your new deal starts. Always ask about this when you’re arranging things.
Can I switch if I’m self-employed?
Yes, though you’ll need to show 2-3 years of accounts or tax returns usually. Some lenders are more self-employed friendly than others – a broker can point you in the right direction.
Is there ever a bad time to switch?
If you’re in a fixed deal with hefty early repayment charges, switching before it ends rarely makes financial sense. Do the maths first.
Ready to Take the Next Step?
