How Long Does Remortgaging Take? The Complete Guide to What Really Happens

You’d think remortgaging would be quick.
After all, you already own the house, you’ve been paying your mortgage for years, and your lender knows you inside out. How hard can it be to switch to a new deal?
Well – it depends.
Sometimes it’s lightning fast. You could be done in under two weeks if you’re staying with the same lender. Other times, especially if you’re switching lender or raising extra funds, it can drag on for six to eight weeks (occasionally longer).
It’s not that the process is complicated – it’s just full of small moving parts. And if one slows down, the rest follow suit.
So, let’s walk through what really happens, what slows it down, and how you can keep things moving.
Understanding the Basics: What Remortgaging Actually Involves
Before we get to timeframes, it helps to be clear on what’s actually happening.
Remortgaging isn’t just renewing your mortgage deal – it’s taking out a new mortgage on your existing home, either with your current lender or a new one.
There are two main routes, and the difference between them massively affects how long it takes:
| Type | Description | Typical Timeframe |
|---|---|---|
| Product transfer (same lender) | You stay with your existing lender but switch to a new rate or product | 1–2 weeks |
| Full remortgage (new lender) | You move your mortgage to a completely different lender | 4–8 weeks |
A product transfer is quick because the lender already holds all your details – they often don’t need a new valuation or affordability assessment.
A full remortgage, however, is a bit like applying for a mortgage from scratch. You’ll go through affordability checks, valuation, legal work, and document verification.
It’s not bad – just slower.
The Typical Remortgage Timeline (Step-by-Step)
Every case is different, but here’s the usual sequence most homeowners go through:
| Stage | What Happens | Average Duration |
|---|---|---|
| 1. Research and decision-making | Compare rates, speak to an adviser, choose a lender | 1–2 weeks |
| 2. Application submitted | You (or your broker) apply for the new deal | 1–2 days |
| 3. Lender assessment | Credit checks, affordability review, request documents | 1–2 weeks |
| 4. Property valuation | Lender arranges valuation (often desktop) | 1–2 weeks |
| 5. Offer issued | Mortgage offer produced once checks complete | 3–6 weeks total so far |
| 6. Conveyancing and completion | Legal work, redemption statement, funds transferred | 1–3 weeks |
| Typical total | 4–8 weeks |
In a best-case scenario, everything lines up neatly and you complete in under a month. But in reality, paperwork delays, missed documents, or slow solicitors can easily double that.
Why It Sometimes Takes Longer
Here’s where things often slow down – and what you can do about it.
1. Lender processing times
Some lenders are lightning fast. Others… not so much.
If a lender’s underwriting team is backed up or your case is slightly outside their standard policy, expect delays.
Tip: Ask your broker about lender turnaround times. They usually know which ones are bogged down.
2. Property valuation issues
Even if it’s just a remortgage, lenders still need to confirm what the property’s worth.
Sometimes it’s an automated desktop valuation. Easy.
Other times, it’s a full in-person inspection – which can take a week to book, a few days to complete, and another week for the report to land.
And if the valuation comes in lower than expected? That can knock your loan-to-value (LTV) ratio and force you to re-apply for a different product.
3. Document gaps
This one’s surprisingly common. Missing bank statements, unclear payslips, mismatched addresses – all small things that stop a lender from issuing an offer.
Be obsessive with paperwork. Send everything in clearly labelled PDFs. You’d be amazed how many delays come down to admin.
4. Conveyancing bottlenecks
Even though you already own the house, switching lender still involves some legal work.
A solicitor (or the lender’s panel firm) needs to handle the title deeds, repay your existing lender, and register the new charge at the Land Registry.
If you use the lender’s free legal service, great – but it’s worth knowing those firms can be painfully slow because they handle huge volumes of cases.
Sometimes, paying a local solicitor a modest fee can speed things up considerably.
5. Complicated circumstances
If you’re self-employed, using bonuses or commission income, or have credit issues, expect extra scrutiny.
Each explanation or document request adds another few days to the process.
6. Raising additional funds
Borrowing extra money (for home improvements, debt consolidation, etc.) adds another layer of underwriting.
Lenders want to know what the funds are for and how they affect affordability.
That can add a week or two easily.
The Fastest Possible Route: Product Transfers
If your priority is speed, there’s no contest – a product transfer wins hands down.
These can often be completed entirely online in under ten days, sometimes within a week if your lender’s systems are efficient.
Here’s why they’re so quick:
- No valuation (the lender already has the figure on file).
- No legal work – you’re not changing lender.
- No affordability assessment if your balance and term remain the same.
Essentially, it’s a quick refresh of your deal, not a brand-new application.
The downside? You’re limited to whatever your current lender offers.
If their rates aren’t competitive, you could be missing out on hundreds of pounds a year in savings – which is why some people accept a slower process for a better long-term result.
Switching Lenders: What to Expect Week by Week
For a full remortgage, here’s a rough timeline based on thousands of UK cases:
Week 1:
You or your broker submit the application, upload documents, and the lender runs a credit check.
Week 2:
Valuation arranged. Sometimes desktop, sometimes a surveyor visit. You’ll usually get a notification once it’s booked.
Week 3–4:
Underwriting team reviews your file, may request extra payslips, SA302s, or proof of deposit (if you’re capital raising).
If everything’s in order, the offer is issued around week four.
Week 5–7:
Solicitors handle the legal work – redeem your old mortgage, handle ID checks, confirm buildings insurance, draw down funds.
Week 8:
Completion. Your new mortgage replaces the old one. You’ll get a completion statement confirming the old loan’s been paid off.
That’s the ideal flow. But – and there’s always a “but” – a single missing document or delay in valuation can easily stretch that by another couple of weeks.
Common Questions (And Honest Answers)
Can I remortgage before my current deal ends?
Yes, and often you should start early.
You can usually secure a new deal up to six months before your current one expires. The new rate can then begin immediately after the old deal ends – avoiding any time on the expensive Standard Variable Rate (SVR).
Does remortgaging cost money?
It can. Even though many lenders advertise “free legals” and “no valuation fees”, there are still potential costs:
| Cost Type | Typical Amount |
|---|---|
| Arrangement fee | £0 – £999 |
| Valuation fee | Often free |
| Legal fees | Usually free or £300–£500 if using own solicitor |
| Exit fee (from old lender) | £75 – £300 |
| Early repayment charge | 1–5% of balance if leaving deal early |
Factor those in before making your decision.
Will remortgaging affect my credit score?
Only temporarily.
A full remortgage involves a hard credit check, which can dip your score slightly. But it usually bounces back within a month or two, assuming you maintain other commitments.
Can I speed things up?
Definitely. Here’s how:
- Have all documents ready before you apply – payslips, bank statements, ID.
- Respond to any lender or solicitor requests the same day.
- Use a proactive broker who chases updates regularly.
- If time is critical, avoid “free legals” and pay for your own solicitor instead.
- Start early – ideally three months before your deal ends.
In short, control what you can and anticipate what you can’t.
How Long Does a Remortgage Take With Each Lender?
Timeframes vary slightly depending on who you go with.
Here’s a rough idea based on average UK lender data and feedback from brokers:
| Lender Type | Typical Completion Time |
|---|---|
| Big high-street banks (Barclays, Halifax, NatWest, etc.) | 4–6 weeks |
| Building societies | 5–8 weeks |
| Specialist lenders | 6–10 weeks |
| Online / digital lenders | 3–5 weeks |
| Product transfers (any lender) | 1–2 weeks |
These aren’t official figures – just typical real-world experience.
And yes, the irony’s not lost that the biggest, most established banks can sometimes be the slowest.
What Happens on Completion Day?
It’s not a dramatic event – no need for champagne corks.
Your solicitor receives the new mortgage funds from the new lender and immediately pays off your existing mortgage in full.
If you’re borrowing extra, that surplus lands in your bank account shortly after.
Then the solicitor registers the new lender’s charge at the Land Registry (a process that can take weeks behind the scenes, but doesn’t affect you).
You’ll get a completion statement confirming the switch.
From there, you simply start making payments to the new lender on the date they set out.
How to Avoid Overlaps or Gaps Between Deals
Timing is everything.
If your current mortgage deal ends on, say, the 1st of June, you want your new one to start on or before that date to avoid rolling onto the SVR.
A good broker or solicitor will plan this carefully, so the transition is seamless.
You can usually set your completion date up to three months in advance, which helps line things up perfectly.
When It’s Worth Starting the Process Early
In my experience, the sweet spot for starting a remortgage is three to four months before your current deal expires.
That gives you time to compare options, secure a rate, and let the paperwork run its course – without stress or overlap.
And with markets being unpredictable, fixing early can protect you from rate hikes that could happen while you wait.
The Role of Advice and Market Access
If you’re unsure where to start, or if your situation isn’t perfectly straightforward (most aren’t), it’s worth reading up on remortgage advice.
That page explains how brokers can compare thousands of deals across more than 90 lenders – including exclusive ones you can’t get directly – and how they handle the admin so you don’t have to.
It’s not about pushing you one way or another. It’s about getting you the right rate, at the right time, with minimal hassle.
Final Thoughts
So, how long does remortgaging take?
Anywhere from a week to two months, depending on the route you take – and how organised you are.
If you’re staying with your lender, it’s a quick win.
If you’re switching, it’s a small project – but one that can save you thousands over the years.
In truth, it’s rarely the process that causes stress – it’s the uncertainty.
Once you know the stages and what to expect, the whole thing feels much more manageable.
And remember: starting early is the best way to make sure your timing’s spot-on and your wallet stays happy.
