Remortgage timeline: how long it takes and when to start looking
A standard remortgage takes around 4 to 8 weeks from application to completion, though more complex cases can take longer. You should start comparing deals 3 to 6 months before your current one ends, so you have time to complete the switch before moving onto your lender’s standard variable rate.
This guide covers what remortgaging actually involves, how it differs from a product transfer, what happens at each stage, and the documents you’ll need to have ready.

What is a remortgage, and how is it different from a product transfer?
A remortgage is when you replace your existing mortgage with a new deal, either with your current lender or a different one, without moving home. People remortgage to secure a better interest rate, reduce their monthly payments, or release equity to fund home improvements or other costs.
If you stay with your current lender and simply move onto one of their new rates, that’s called a product transfer, not a remortgage. It’s usually quicker, since it involves fewer checks and less paperwork, and doesn’t typically require a solicitor or a property valuation. A full remortgage to a new lender takes longer because the new lender needs to assess you as a new customer, but it’s worth comparing the market anyway. Your current lender’s offer isn’t always the most competitive one available to you.
One of the most common reasons people remortgage is to avoid drifting onto their lender’s standard variable rate (SVR) once a fixed deal ends. SVRs are usually higher than the fixed or tracker rates available elsewhere, which is why starting the process early matters.
When can you remortgage without paying an early repayment charge?
Most fixed and tracked deals carry an early repayment charge (ERC) if you remortgage before the deal ends, commonly somewhere between 1% and 5% of your outstanding balance, though this varies by lender and by how far you are into your term.
Before starting the process, check your current mortgage statement or annual review letter for:
- When your current deal actually ends
- Your current interest rate
- Whether an ERC applies, and how much it would be
- Any other exit fees, such as a mortgage account or deeds release fee
If switching early would cost more in ERC than you’d save on a new rate, it’s usually worth waiting until your deal ends, unless you need to release equity or change your mortgage for another reason that outweighs the charge.
How long does each stage take?
Remortgage timeline, stage by stage
-
Research and preparation
1–2 weeks
Speak to an adviser, compare rates, and gather your documents.
-
Application and submission
~1 week
Your application and supporting documents go to the lender.
-
Valuation and underwriting
2–3 weeks
The lender values your property and reviews your credit and affordability.
-
Legal work
If switching lender
A conveyancer handles the legal side of moving to a new lender. Not usually needed for a product transfer.
-
Mortgage offer issued
2–4 weeks from application
Your formal offer arrives once all checks are complete.
-
Completion
Agreed date
Your new mortgage begins and your existing one is repaid.
Research and preparation (1 to 2 weeks). Speaking to a mortgage adviser, comparing rates, and gathering your ID and income documents. A whole-of-market broker can assess your circumstances, including your income, outgoings, property value, and how much you want to borrow, and identify suitable options faster than researching lenders individually.
Application and submission (around 1 week). Your adviser submits your application to the chosen lender, along with your supporting documents.
Valuation and underwriting (2 to 3 weeks). The lender values your property and reviews your credit history and affordability.
Legal work (if switching lender). A conveyancer or solicitor handles the legal side of moving your mortgage to a new lender. Some deals include free legal work and a standard valuation, others charge for it, so check what’s included before you apply. Product transfers don’t usually need this step at all.
Mortgage offer. Once checks are complete, you’ll receive a formal mortgage offer, typically 2 to 4 weeks after application.
Completion. Your conveyancer arranges for your existing mortgage to be repaid using funds from your new lender, and your new mortgage begins on the agreed completion date. If this happens before your current deal ends, you avoid moving onto the SVR.
What documents do you need for a remortgage?
Documents you'll need
| Proof of identity: valid passport or UK driving licence | |
| Proof of address: recent utility bill, council tax bill, or bank statement | |
| Proof of income: employed: latest 3 months' payslips and P60. Self-employed: 2–3 years' SA302s and Tax Year Overviews (varies by lender) | |
| Bank statements: latest 3 months, showing income and everyday spending | |
| Financial commitments: loans, credit cards, childcare costs | |
| Current mortgage statement: outstanding balance, current rate, any ERC that applies |
Common mistakes when remortgaging
- Leaving it too late. Waiting until your deal has already ended means you’re on the SVR while a new remortgage completes, which can cost more than the rate you’re trying to avoid.
- Not checking for an ERC before applying. Some homeowners start a full application before realising switching early will cost more in charges than they’ll save.
- Assuming staying put is simplest, and therefore best. A product transfer is often quicker, but it’s still worth comparing whole-of-market rates first. Your current lender’s offer isn’t reviewed against the rest of the market unless you ask someone to do that for you.
- Not accounting for a change in circumstances. Affordability criteria can shift between mortgage deals, so a change in income, credit score, or outgoings since you last applied can affect what’s available to you now.

FAQs
How long does a remortgage take?
A standard remortgage usually takes 4 to 8 weeks from application to completion, though more complex cases, such as those involving self-employed income or a higher loan-to-value ratio, can take longer. Starting 3 to 6 months before your current deal ends gives you enough time to compare options and complete before moving onto a standard variable rate.
What's the difference between a remortgage and a product transfer?
A remortgage moves your mortgage to a new lender, while a product transfer keeps you with your existing lender on a new rate. Product transfers are usually faster and involve less paperwork, but your current lender's rate isn't automatically the most competitive one available, so it's worth comparing the market either way.
Will I have to pay an early repayment charge if I remortgage?
You may, if you switch before your current deal ends. ERCs are commonly between 1% and 5% of your outstanding balance, depending on your lender and how far into your term you are. Some homeowners choose to wait until their deal ends to avoid this, unless the savings from switching early outweigh the charge.
Do I need a solicitor or a valuation to remortgage?
Usually, yes, if you're switching to a new lender, though some deals include free legal work and a standard valuation. If you're doing a product transfer with your existing lender instead, a solicitor and valuation typically aren't required.
Does Heron Financial charge a fee for remortgage advice?
No. Heron Financial is fee-free and whole-of-market, so advice on remortgaging doesn't cost you anything, and our advisers can compare deals across the market rather than a single lender's range.
Can Heron Financial help if I want to release equity as part of my remortgage?
Yes, our advisers can talk through releasing equity as part of a remortgage, for example to fund home improvements, alongside comparing whether a new rate or lender makes sense for your circumstances.
What happens if I do nothing when my mortgage deal ends?
You'll usually move onto your lender's standard variable rate automatically, which is typically higher than the fixed or tracker rates available elsewhere. This is the main reason to start comparing options before your deal ends, rather than after.
