Should you take a secured loan or remortgage to raise funds? Compare costs, speed, flexibility and risks to decide which option suits your situation in the UK.
Both a secured loan and a remortgage let you access the equity in your property, but they work in fundamentally different ways. A remortgage replaces your existing mortgage with a new, larger one — you borrow more than your current balance and take the surplus as cash. A secured loan (also called a second charge mortgage) sits alongside your existing mortgage as a separate debt, leaving your current deal completely untouched.
The right choice depends on your current mortgage deal, how much you need to borrow, your credit profile, and how quickly you need the funds. Neither option is universally better — it depends entirely on your circumstances.
If you locked in a competitive fixed rate — especially one from 2020-2022 when rates were at historic lows — remortgaging would mean giving it up for a significantly higher rate on the full balance. A secured loan only applies the higher rate to the additional borrowing, keeping your existing deal intact. Over the remaining fixed term, this can save thousands of pounds.
Fixed-rate mortgages typically carry early repayment charges (ERCs) of 1-5% of the outstanding balance if you exit before the end of the fixed period. On a £250,000 mortgage, that could be £2,500 to £12,500. A secured loan avoids these charges entirely because your mortgage stays in place.
Secured loans typically complete in 2-4 weeks. Remortgages usually take 6-12 weeks. If you need money urgently — for a time-sensitive property purchase, emergency repairs, or a business opportunity — a secured loan is significantly faster.
If your credit score has worsened since you took out your mortgage, you may not qualify for a competitive remortgage rate. In this situation, keeping your existing mortgage (at the rate you were originally approved for) and taking a separate secured loan is often cheaper overall.
If your fixed rate has expired and you have moved to your lender's standard variable rate (SVR), there is little reason to keep the existing mortgage. SVRs are typically 7-8% in 2026 — far higher than the best fixed rates. Remortgaging replaces the expensive SVR with a competitive new deal and lets you raise additional funds at the same time.
A remortgage gives you one monthly payment, one lender, and one deal to manage. A secured loan means two separate debts with different lenders, rates, and terms. Some borrowers value the simplicity of a single arrangement.
If your current mortgage rate is not particularly competitive — or if you are already on a variable rate — the combined cost of a new mortgage (including fees) may work out cheaper than keeping the old mortgage and adding a secured loan at a higher rate. This is a calculation a broker can run for you precisely.
For amounts under £15,000-£20,000, the fixed costs of a secured loan (valuation, legal fees, broker fees) can make it disproportionately expensive. Remortgaging — or even an unsecured personal loan — may be more cost-effective for smaller sums.
To determine which option is genuinely cheaper, you need to compare the total cost of borrowing over the full term of each option. Key factors include:
Example scenario: Current mortgage: £200,000 at 2.5% fixed (3 years remaining, 3% ERC). Need to borrow: £40,000. A remortgage at 4.8% on £240,000 plus £6,000 ERC costs significantly more over 3 years than keeping the 2.5% mortgage and taking a £40,000 secured loan at 7%. The broker maths makes this clear.
A further advance means borrowing additional money from your existing mortgage lender. It keeps everything with one provider but the extra borrowing is usually at a different (often higher) rate than your main mortgage. Not all lenders offer further advances, and they can be slow to arrange. For more detail, see our guide to secured loan vs further advance.
Both options put your home at risk. If you fall behind on either a remortgage or a secured loan, your property could be repossessed. The key difference is that with a secured loan, two lenders have a claim on your property — which can complicate matters if you face financial difficulty.
The best way to determine the right option is to work with a specialist broker who can model both scenarios using your exact figures. They will calculate the total cost of each route over the full term, factoring in all fees, ERCs, and interest charges. Many borrowers are surprised by the result — the answer is not always what you would expect.

Secured Loan is a specific financial product or arrangement available in the UK market. Understanding exactly how it works is essential before you can make a meaningful comparison with alternatives.
In practical terms, secured loan involves a defined structure with its own set of terms, eligibility requirements, and cost implications. The way it is regulated by the FCA and the protections available to consumers depend on the specific product type.
Before committing to secured loan, it is worth understanding the full range of benefits and limitations so you can assess whether it genuinely suits your circumstances.
Remortgage takes a different approach and may suit different circumstances or priorities. Like secured loan, it is available through regulated providers in the UK and comes with its own set of advantages and trade-offs.
The key difference in how remortgage works often comes down to the structure, cost, flexibility, or the level of protection it provides. Some people prefer it because of its simplicity, while others value the specific features it offers.
Understanding both options in detail allows you to make an informed choice rather than relying on assumptions or marketing claims.
While secured loan and remortgage may appear similar on the surface, there are important differences that can significantly affect the value you receive and the level of protection or return you can expect.
The differences typically fall into several categories: cost structure, eligibility criteria, flexibility, tax treatment, and the level of risk involved. Your personal circumstances, financial goals, and risk tolerance should guide which of these differences matters most to you.
Every financial product involves trade-offs, and the choice between secured loan and remortgage is no exception. Listing the advantages and disadvantages side by side can help clarify which option aligns better with your priorities.
Secured Loan tends to be preferred by those who value certain features like stability, simplicity, or specific tax advantages. Remortgage, on the other hand, may appeal to those who prioritise flexibility, lower costs, or a different risk-return profile.
There is no universally correct answer. The best choice depends entirely on your individual situation, goals, and appetite for risk.
Secured Loan is typically the better option when your priority is stability, predictability, or when your circumstances match the specific eligibility criteria where it offers the greatest value.
In particular, secured loan may be more appropriate if you have a longer time horizon, a specific tax planning need, or if you want the security of knowing exactly what you will receive or pay over the full term.
Remortgage tends to be the stronger choice when flexibility is important, when you want to keep your options open, or when the cost savings compared to secured loan are significant enough to outweigh any trade-offs.
It may also be preferable if your circumstances are likely to change in the near future, as the ability to adjust without penalty can be valuable.
