What Does It Mean When You Remortgage?
Remortgaging means switching your existing mortgage to a new deal — either with your current lender (a product transfer) or with a completely different one. Your property stays the same; it's the mortgage agreement that changes.
Most homeowners remortgage when their initial fixed or tracker rate ends. If you don't arrange a new deal, you'll be moved onto your lender's Standard Variable Rate (SVR), which is almost always significantly higher — often 2–3% more than the best remortgage rates available.
How Does Remortgaging Work?
When you remortgage, you replace your existing mortgage with a new one. Here's the process:
Valuation
Your new lender arranges a property valuation to confirm current market value
Legal Transfer
A solicitor handles the legal transfer between lenders (often free)
Completion
Your old mortgage is paid off and the new deal begins
If you're doing a product transfer (staying with the same lender), no valuation or solicitor is needed — making it faster and simpler, though not always the cheapest option.
Is Remortgaging a Good Idea?
For most homeowners, remortgaging is a very good idea when your current deal is ending.
When It's Worth It
- Fixed rate ending within 6 months
- Already on the SVR and overpaying
- Property risen in value → lower LTV
- Want to release equity for improvements
- Interest rates have dropped
Watch Out For
- Early Repayment Charges (1–5% of balance)
- Arrangement fees can add up
- Extending the term = more total interest
- Negative equity limits options

Why Remortgage? Common Reasons
Deal ending
Avoid slipping onto the expensive SVR
Better rate
Rates dropped or your LTV improved
Pay off faster
Switch to allow overpayments without penalties
Consolidate debts
Roll other debts into your mortgage
Release equity
Access value for improvements or helping family
Change type
Switch between interest-only and repayment
You can pay off a 25-year mortgage in 15 years by overpaying consistently.
When Should You Remortgage — and When Not To?
Start looking 3–6 months before your current deal expires. Most lenders hold mortgage offers for 3–6 months, giving you plenty of runway.
When NOT to Remortgage
- You have large ERCs remaining — the exit penalty may outweigh savings
- Your credit has deteriorated significantly
- You're planning to move soon — a product transfer may be simpler
- The fees eat into your savings — always calculate total cost
Do You Need a Deposit?
No cash deposit is needed. Your existing equity acts as your deposit. Best deals typically come at 75% LTV or lower.
How Much Can I Borrow When I Remortgage?
Lenders typically offer up to 4.5x your annual income, though some go to 5.5x for higher earners.
Example: Releasing Equity
Home worth £300,000 • Current mortgage £150,000
£300k
Property Value
£150k
Current Balance
£120k
Max Equity Release (90% LTV)
What Salary Do I Need for a £300k Mortgage?
At a standard 4.5x multiplier, you'd need approximately £66,700 household income. Some lenders stretch to 5.5x (around £54,500). Use our mortgage calculator for a personalised estimate.

How to Compare Remortgage Rates and Find the Best Deals
Finding the most competitive remortgage rates requires comparing more than just headline rates:
- Overall cost: Factor in arrangement fees — a 1.5% rate with a £2,000 fee may cost more than a 1.7% fee-free deal
- Compare the market: A broker searches the whole market in minutes
- Check the APRC: Includes fees for a truer cost picture
- Consider the term: Shorter terms = higher payments but less total interest
Current Best Rates (Early 2026)
3.5–4.0%
2-year fixed (40%+ equity)
3.7–4.2%
5-year fixed (40%+ equity)

Remortgaging to Release Equity
If your property has increased in value, you can borrow against this equity for:
- Home renovations or extensions
- Helping children onto the property ladder
- Debt consolidation
- Buying a second property or buy-to-let
Important: Releasing equity increases your mortgage balance, meaning higher monthly payments.
What Does Martin Lewis Say About Equity Release?
Martin Lewis advises caution — explore all alternatives first including standard remortgaging, downsizing, or borrowing from family. See our equity release guide.
