Many UK homeowners are looking to tap into their property equity for home improvements or debt consolidation. Deciding between a secured loan and a remortgage depends on your existing interest rate, the fees involved in switching lenders, and how much you need to borrow.
What is the difference between a secured loan and a remortgage?
A remortgage involves replacing your current mortgage with a brand-new deal, typically for a larger amount than your existing balance. You use the extra funds for your own purposes, and you are left with a single monthly payment to one lender.
A secured loan, also known as a second charge mortgage, sits 'behind' your main mortgage. It is a completely separate agreement with its own interest rate and term. You will have two monthly payments: one to your original mortgage provider and one to the secured loan provider.
Why the 2026 market context matters
When this article was published in July 2026, Bank Rate was 3.75% and many homeowners were still locked into fixed rates taken out in 2024 or 2025. If you have a competitive rate of 4% or less, remortgaging might force you to give up that rate on your entire balance. In this scenario, a secured loan for just the additional funds often makes more financial sense.
How does a secured loan work?
When you take a secured loan, the lender uses your home as collateral. Because they are the 'second' claimant if the property is repossessed, they take on more risk than the primary lender. This is why interest rates for secured loans are higher than standard mortgage rates.
Pro Tip: Before committing to a secured loan, always check your current mortgage deed. Some lenders require 'consent to mortgage' before you can take out a second charge.
Is it cheaper to remortgage or take a secured loan?
To determine the cheapest route, you must calculate the 'total cost of borrowing' over the term. This includes interest, arrangement fees, and any Early Repayment Charges (ERCs) from your current lender.
| Feature | Remortgage | Secured Loan |
|---|---|---|
| Interest Rates | Lower (first-charge pricing) | Higher (second-charge premium) |
| Setup Fees | £0 – £2,000 | £500 – £3,000 |
| Impact on main mortgage | Replaces it entirely | No change to original rate |
| Speed of completion | 4 to 8 weeks | 2 to 3 weeks |
| Max Loan-to-Value | Usually 85-90% | Up to 95% in some cases |
Comparing the costs: An illustrative example (rates are examples only, not current quotes)
Imagine you have a £200,000 mortgage at 3.5% with three years left on the fixed term. You want to borrow an extra £30,000 for a kitchen extension.
- Remortgage path: If you remortgage the full £230,000 at a new rate of 4.8%, your interest costs on the original £200,000 rise significantly. You might also pay a 3% ERC, costing you £6,000 upfront.
- Secured loan path: You keep your £200,000 at 3.5% and only pay 8% interest on the new £30,000. While 8% sounds high, you avoid the £6,000 penalty and keep your low rate on the bulk of your debt.
Why do people choose a secured loan over a remortgage?
There are several specific reasons why a second charge might be the superior option under current FCA mortgage reforms:
- High Early Repayment Charges: If you are in the middle of a fixed-term deal, the penalty to leave could be thousands of pounds.
- Low Interest Rates: If your current mortgage rate is lower than what is currently available on the market, you should avoid touching it.
- Credit Score Changes: If your credit rating has dipped since you took out your original mortgage, you might not qualify for a competitive remortgage rate. Secured loan lenders are often more flexible with credit history.
- Employment Type: If you have recently become self-employed, a secured loan lender might accept one year of accounts, whereas a high-street remortgage lender might require two or three.
What is the process for remortgaging?
Remortgaging is often a more formal process. It involves a full valuation of your home and a legal process to switch the title deed from one lender to another. We recommend checking our remortgage services to see if you qualify for the latest deals.
- Fact-find: We assess your income, outgoings, and equity.
- Decision in Principle: We find a lender willing to offer you the new amount.
- Application: Submission of payslips and bank statements.
- Valuation and Legal: The lender checks the property value and a solicitor handles the transfer.
When is remortgaging the better option?
If your current fixed-rate deal is coming to an end, remortgaging is almost always the better choice. It allows you to consolidate all your debt into one loan at a lower interest rate than most unsecured borrowing. You can use our mortgage calculators to see how a new rate might affect your monthly outgoings.
Pro Tip: If you are consolidating unsecured debt (like credit cards) into a mortgage, remember that while the monthly payment falls, you may pay more interest over the long term by extending the debt over 25 years.
Assessing the risks
Both options involve securing debt against your home. This means if you fail to keep up with repayments, your property could be repossessed. In the 2026 market, with the cost of living still a factor, we always advise looking at mortgage protection insurance to cover your payments in case of illness or redundancy.
What I tell my clients
"Whenever a client asks me which is better, I always start by looking at their current mortgage statement. If you are sitting on a 'legacy' low rate from the early 2020s, I will almost never suggest a remortgage because the maths simply doesn't work. However, for those on standard variable rates or near the end of their term, remortgaging is the natural winner for saving money. We look at the 'product' vs the 'penalty' every single time." — Matt
