1. What Is Remortgaging?
Remortgaging means switching your mortgage to a new deal — either with your current lender (called a product transfer) or with a new lender entirely. You're not moving home; you're changing the terms of how the property is financed.
People remortgage for several reasons:
- Their current fixed-rate deal is ending and they want to avoid the SVR
- Rates have fallen and they can get a better deal mid-term (if ERC permits)
- Their property has increased in value, improving their LTV tier
- They want to release equity for home improvements or other purposes
- They want to change the mortgage term — extend it to reduce payments, or shorten it
- They want to switch from interest-only to repayment
The SVR trapWhen a fixed or tracker deal ends, lenders automatically move you to their Standard Variable Rate (SVR). SVRs in 2026 are typically 6–8% — often 2–3% above the best available fixed rates. On a £200,000 mortgage, this costs an extra £200–£400/month. Set a diary reminder 6 months before your deal end date.
2. When to Remortgage
Before your deal ends (3–6 months ahead)
Most lenders allow you to lock in a new rate up to 6 months before your current deal ends. You complete the application now, but don't switch until the end of your current deal. This means you can:
- Avoid any gap on SVR
- Take time to shop around without rushing
- Still benefit if rates fall further before you switch (some lenders let you renegotiate)
Mid-deal (with an ERC)
Sometimes it's worth switching even before the deal ends — particularly if you're on a high rate from 2023 (when rates peaked at 5.5–6%) and rates have since fallen significantly. Run the numbers: if the monthly saving covers the ERC within a reasonable break-even period, switching may be worthwhile.
Use the Remortgage Calculator to see your break-even point.
Already on SVR
If you've already reverted to your lender's SVR, remortgage immediately. Every month on SVR you're almost certainly overpaying. There is no ERC on SVR — you can leave at any time.
3. Early Repayment Charges (ERCs)
An ERC is a penalty for leaving a fixed-rate mortgage before the deal ends. ERCs are typically expressed as a percentage of the outstanding mortgage balance and reduce each year of the deal:
| Year of 5yr deal | Typical ERC | On £200,000 balance |
|---|---|---|
| Year 1 | 5% | £10,000 |
| Year 2 | 4% | £8,000 |
| Year 3 | 3% | £6,000 |
| Year 4 | 2% | £4,000 |
| Year 5 | 1% | £2,000 |
Break-even rule of thumbIf your monthly saving is £200 and the ERC is £4,000, break-even is 20 months. If you're staying in the property for more than 20 more months and want certainty, switching may make sense even with the ERC. Calculate your break-even using the Remortgage Calculator.
4. How LTV Affects Your Remortgage Rate
Loan-to-Value (LTV) is one of the biggest factors in the rate you're offered. Lower LTV = lower risk for the lender = cheaper rate.
| LTV Band | Typical 5yr Fixed Rate (2026) | Example: £200k mortgage |
|---|---|---|
| 60% LTV | ~3.85% | £950/mo on 20yr term |
| 70% LTV | ~3.95% | £965/mo on 20yr term |
| 75% LTV | ~4.05% | £975/mo on 20yr term |
| 80% LTV | ~4.25% | £1,000/mo on 20yr term |
| 85% LTV | ~4.55% | £1,030/mo on 20yr term |
| 90% LTV | ~4.80% | £1,060/mo on 20yr term |
If your property has risen in value since you bought it, your LTV may now be lower — potentially qualifying you for a better rate tier. Before remortgaging, check your estimated current property value and recalculate your LTV.
5. Product Transfer vs Full Remortgage
Product Transfer (stay with current lender)
- No valuation required
- No legal/conveyancing work
- Often completable online in minutes
- Rate may not be as competitive as the open market
- No credit search (usually)
Full Remortgage (switch to new lender)
- Access to the full market — potentially better rates
- Requires a full mortgage application
- Valuation (usually free on remortgage products)
- Legal work (often free on remortgage products)
- Hard credit check
- Takes 4–8 weeks to complete
Strategy:Always get your current lender's product transfer quote first, then compare it to the open market. If the rate difference is small (<0.2%), the product transfer's speed and simplicity may be preferable. If the market is significantly cheaper, a full remortgage is worth the effort.
The Remortgage Process (full switch)
- Research and get an AIP
Use a comparison site or broker to find the best rate for your LTV and circumstances. Get an Agreement in Principle before applying.
- Full mortgage application
Submit income evidence, bank statements, and property details. The lender conducts a full credit check and affordability assessment.
- Valuation
The new lender values your property. On most remortgage products this is free and often done automatically using automated valuation models (AVMs).
- Mortgage offer issued
Usually takes 2–4 weeks from application. The offer is valid for 3–6 months.
- Legal work
Your solicitor (often provided free by the new lender) handles the transfer of the mortgage charge. No property changes hands — it's simpler than purchasing.
- Completion
The new mortgage replaces the old one. The new lender pays off the old lender. Done.
6. Remortgaging to Release Equity
If your property is worth more than when you bought it, or you've paid down the balance significantly, you can remortgage for more than your outstanding balance — releasing the difference as cash. This is called a capital raise.
| Scenario | Detail |
|---|---|
| Property value at purchase | £280,000 |
| Mortgage at purchase | £210,000 (75% LTV) |
| Property value now | £340,000 |
| Outstanding balance now | £185,000 |
| Current LTV | 54% (£185k ÷ £340k) |
| New mortgage at 70% LTV | £238,000 |
| Equity released | £53,000 (£238k − £185k) |
Equity release through remortgaging adds to your mortgage debt and increases monthly payments. Lenders assess affordability on the new, higher amount. Common uses: home improvements, buying an investment property deposit, debt consolidation, school fees.
Debt consolidation cautionRolling unsecured debt (credit cards, personal loans) into a mortgage converts short-term debt into a 20+ year obligation secured against your home. Total interest paid is often much higher even at a lower rate. Only consolidate after careful consideration — speak to an independent adviser.
