Remortgage vs Product Transfer Details
📊 Remortgage vs Transfer Breakdown
When your current fixed-rate mortgage deal approaches expiry, UK homeowners face a key decision: Remortgage to a new lender or perform a Product Transfer with your existing lender.
- Remortgage (Switching Lenders): Involves moving your mortgage debt to a completely new financial institution. This requires a new credit check, affordability assessment, legal conveyancing, and property valuation, but may unlock lower headline interest rates.
- Product Transfer (Staying with Current Lender): Involves switching to a new fixed-rate deal with your existing bank. It requires no legal work, no credit checks, and no new affordability assessment, but the interest rate offered may be slightly higher.
To determine which path yields the lowest total expenditure over a 2-year or 5-year fixed term, you must compare the combined total of monthly interest payments PLUS arrangement/setup fees.
⚙️ Rules & Thresholds
- Total Deal Cost Formula:
(Monthly Payment × Deal Months) + Arrangement Fees + Legal/Valuation Fees. - Product Transfer Advantages: Zero legal costs, zero valuation fees, paperless 5-minute online sign-up, no income verification.
- Remortgage Advantages: Access to lower market interest rates across all UK lenders; free standard legal and valuation packages offered by many competing lenders.
- Standard Variable Rate (SVR) Trap: Failing to secure a product transfer or remortgage before your fixed deal expires drops your mortgage onto your lender’s expensive SVR (typically 7.5% to 8.5% EAR).
📊 Practical Examples
- Option A (New Lender Remortgage): 4.25% interest rate + £999 arrangement fee.
- Option B (Current Lender Product Transfer): 4.45% interest rate + £0 fees.
- Option A Monthly Payment: £1,085.34 / month (£65,120.40 over 5 yrs + £999 fee = £66,119.40 total).
- Option B Monthly Payment: £1,107.50 / month (£66,450.00 over 5 yrs + £0 fee = £66,450.00 total).
Result: Switching to New Lender saves £330.60 net over the 5-year fixed term despite paying a £999 fee.
📑 Common Pitfalls
- Looking Only at Headline Rates without Factoring Arrangement Fees: A 4.15% rate with a £1,499 fee on a small £100,000 loan is significantly more expensive overall than a 4.40% rate with £0 fees!
- Leaving Remortgaging Until the Last Minute: Start comparing remortgage options 4 to 6 months before your fixed deal expires to secure a rate lock without dropping onto SVR.
- Ignoring Property Valuation Upgrades: If your house value has increased, your Loan-to-Value (LTV) bracket may drop from 80% to 75%, unlocking lower interest rate tiers.
❓ Frequently Asked Questions (FAQ)
A remortgage involves moving your mortgage to an entirely new lender, which requires credit checks, income verification, property valuation, and legal conveyancing. A product transfer means switching to a new fixed rate with your current bank, requiring no credit checks or legal work.
Most UK mortgage lenders allow you to secure a new fixed-rate mortgage offer up to 6 months in advance. You can lock in a new interest rate offer now, which will automatically take effect on the exact day your current deal expires without incurring early repayment charges.
No. Provided you are not borrowing extra money or extending your term, UK banks do not conduct credit checks or affordability reassessments for an existing customer completing a product transfer.
Adding an arrangement fee (e.g. £999) to your mortgage balance avoids upfront cash payout, but interest will be charged on that £999 over your remaining 20-30 year mortgage term, costing significantly more overall. Paying fees upfront is cheaper if cash is available.
