Secured Loan
vs Remortgage

Need to raise money against your property? The two main options are a secured loan (second charge) or remortgaging. This guide explains when each option makes sense — and how to choose.

Last updated: March 2026

Quick Answer

Whether a secured loan or remortgage is better depends on your circumstances. A secured loan keeps your existing mortgage rate and deal completely intact, completes faster at 3–6 weeks versus 6–12 weeks for a remortgage, and avoids early repayment charges that can cost thousands. It is the better choice if you have a competitive fixed-rate mortgage you want to protect. Remortgaging may be cheaper if your current deal has ended and you are on the lender's standard variable rate, as first charge rates are typically 4–6% compared to 6–12% for secured loans. However, with a secured loan you only pay the higher rate on the additional borrowing, not your entire mortgage balance. For homeowners locked into a good deal, needing funds quickly, or with changed credit circumstances, a secured loan is usually the more practical and cost-effective option.

The Quick Answer

Choose a Secured Loan if...

  • ✓ You're on a good mortgage rate you don't want to lose
  • ✓ You'd face early repayment charges to remortgage
  • ✓ You need funds quickly (3–6 weeks)
  • ✓ You only need to borrow a relatively small amount
  • ✓ Your credit has worsened since taking your mortgage
  • ✓ You want to keep things separate from your mortgage

Choose Remortgaging if...

  • ✓ Your current mortgage deal has ended (on SVR)
  • ✓ No early repayment charges apply
  • ✓ You can get a better rate than your current deal
  • ✓ You need to borrow a very large amount
  • ✓ You want to consolidate everything into one payment
  • ✓ You have excellent credit

Worked Example: The Real Cost

Let's say you have a £200,000 mortgage at 2.5% fixed with 3 years left on the deal, and you need to raise £30,000 for home improvements.

Option A: Secured Loan

£30,000 at 8.5% over 15 years

Monthly payment: £295

Total interest on £30k: £23,100

Mortgage stays at 2.5%: no extra cost

Total extra cost: £23,100

Option B: Remortgage

£230,000 at 4.5% over 25 years

Monthly payment: £1,278

ERC on current mortgage: £4,000

Extra interest (losing 2.5% on £200k): £18,000+ over 3 years

Total extra cost: £22,000+ (plus lost deal)

In this scenario, the secured loan has a similar total cost but preserves the competitive 2.5% mortgage rate. If interest rates rise further, keeping that deal becomes even more valuable. The secured loan is also faster to arrange and doesn't require restructuring your entire mortgage.

Common Questions

Can I have a secured loan and a mortgage at the same time?
Yes — that's exactly what a secured loan (second charge mortgage) is. It sits behind your existing mortgage as a separate, independent product. You make two separate monthly payments.
Will a secured loan affect my mortgage?
No. Your mortgage terms, rate, and monthly payment remain completely unchanged. The secured loan lender will need your mortgage lender's consent to place a second charge, but this is a formality that your broker handles.
Is a secured loan more expensive than remortgaging?
The interest rate is usually higher, but you're only paying that rate on the additional borrowing — not your entire mortgage. When you factor in early repayment charges and the cost of losing a competitive mortgage rate, a secured loan can work out cheaper overall.
How long does a secured loan take compared to a remortgage?
A secured loan typically completes in 3–6 weeks. A remortgage usually takes 6–12 weeks. If you need funds quickly, a secured loan is significantly faster.
