Remortgage or Secured Loan? How to Choose the Right Option

Updated 10 March 2026 · 8 min read

If you own a home in Wales and need to raise capital — whether for home improvements, debt consolidation, or a large purchase — you’ll likely weigh up two main routes: remortgaging your property or taking out a secured loan (sometimes called a second charge mortgage). Both use your home as security, but they work quite differently in practice. This guide walks through the key differences, when each option makes sense, and how to decide which is right for you.

The key difference

When you remortgage, you replace your entire existing mortgage with a new one — usually with a different lender, and typically for a larger amount so you can release equity. Your old mortgage is paid off, and you start fresh with new terms, a new rate, and a new repayment schedule.

A secured loan, on the other hand, sits alongside your current mortgage as a separate debt. Your existing mortgage stays exactly as it is — same lender, same rate, same monthly payment. The secured loan is registered as a second charge on your property, which is why it’s also called a second charge mortgage. You repay both loans independently, and the secured loan lender is repaid after your mortgage lender if the property is ever sold.

This distinction matters more than it might seem. Which option saves you money — or even which one is available to you — depends heavily on your current mortgage deal, your credit history, and how quickly you need the funds.

When remortgaging makes more sense

Remortgaging is often the more cost-effective option when the timing is right. If your current fixed-rate deal is ending soon — or you’re already on your lender’s standard variable rate — you can move to a new deal without facing early repayment charges (ERCs). In that scenario, you’re effectively getting a fresh start at today’s rates while releasing extra capital in one clean package.

Remortgage rates tend to be lower than secured loan rates because the lender has first charge over the property. If you have strong credit, stable income, and significant equity, a remortgage will usually deliver the cheapest monthly repayments. It also simplifies your finances — one mortgage, one lender, one payment.

The trade-off is speed and flexibility. Remortgages involve full affordability checks, valuation, and conveyancing. Expect the process to take six to eight weeks. If you need funds quickly, or your income situation has become more complex since you took out your current deal, remortgaging may not be straightforward. Learn more about your mortgage options.

When a secured loan is the better option

A secured loan comes into its own when breaking your current mortgage would be expensive or impractical. If you’re mid-way through a competitive fixed-rate deal, the early repayment charges alone could run into thousands of pounds — sometimes wiping out any rate advantage a remortgage might offer. A second charge mortgage lets you keep that existing deal untouched while still accessing your equity.

Secured loans also tend to be faster. Second charge mortgages can often complete in two to three weeks because the process is simpler — there’s no need to redeem your existing mortgage or handle full conveyancing. For borrowers who need funds within a tight timeframe, this speed advantage is significant.

They can also be more accessible if your credit profile has changed since you took out your mortgage. Some secured loan lenders are more flexible on credit history, self-employed income, or complex financial situations than mainstream mortgage lenders. If you’re not confident you’d pass a full remortgage application, a secured loan may be the more realistic route.

Side-by-side comparison

What about early repayment charges?

Early repayment charges are the single biggest factor that pushes people toward a secured loan over a remortgage. ERCs are penalties your current lender charges if you repay your mortgage before the agreed fixed or discounted period ends. They’re usually expressed as a percentage of the outstanding balance — commonly between 1% and 5% — and can add up to a substantial sum.

For example, if you have £200,000 remaining on your mortgage and your ERC is 3%, you’d pay £6,000 just to leave your current deal. That cost needs to be factored into any remortgage comparison. In many cases, the interest savings from a lower remortgage rate simply don’t outweigh the upfront ERC penalty, especially if you only have a year or two left on your fix.

A secured loan sidesteps this entirely. Because your first mortgage stays in place, no early repayment charge is triggered. You borrow what you need as a separate loan, and your existing deal runs its course undisturbed. This makes secured loans particularly attractive for homeowners who are locked into favourable rates they don’t want to lose.

The fixed-rate cliff edge

There’s a specific window where remortgaging becomes especially compelling: when your fixed rate is ending. Most fixed-rate mortgages revert to the lender’s standard variable rate (SVR) when the fix expires, and SVRs are almost always significantly higher. If you don’t act, your monthly payment could jump by hundreds of pounds overnight.

This is the moment to remortgage — you can move to a new deal with no ERC penalty, and you can borrow additional funds at the same time. Most lenders let you start a remortgage application up to six months before your fix ends, so plan ahead. Use our fixed-rate cliff-edge calculator to see how your payments might change.

However, if you need capital before your fix ends and can’t wait, a secured loan gives you access now without triggering charges. You could then remortgage the whole lot — first and second charge — into one clean deal when your fix expires. It’s a strategy that gives you both speed and long-term flexibility.

Can you do both?

Yes — and it’s more common than you might think. Some homeowners take a secured loan now for immediate funding needs, then consolidate everything into a single remortgage when their fixed period ends. This two-step approach works well when timing is the main issue: you get the money you need quickly via a second charge, then tidy up your finances later with a straightforward remortgage.

The key is to plan ahead. If you know your fix is expiring in 12 to 18 months, you can take a shorter-term secured loan now and budget for the remortgage later. A good broker will help you map out this timeline so the numbers work in your favour. Read our full guide to secured loans for more detail on how second charges work alongside your mortgage.

One thing to be aware of: if you have a second charge in place when you come to remortgage, your new mortgage lender will need to agree to it remaining in place — or the secured loan will need to be repaid from the remortgage funds. Either way, it’s manageable with the right advice, but it’s worth factoring into your planning.

How to decide

Start by checking your current mortgage terms. Look at when your fixed rate ends, what your early repayment charges are, and how much equity you have. If your fix is ending soon and you have no ERCs to pay, remortgaging is almost always the better starting point — you’ll get a lower rate and can borrow more in one streamlined deal.

If you’re mid-fix with significant ERCs, or if your income or credit situation has changed, a secured loan deserves serious consideration. Run the numbers both ways: compare the total cost of remortgaging (including ERCs, fees, and the new rate) against the total cost of a secured loan (higher rate, but no ERCs and lower fees). The cheapest option on paper isn’t always the cheapest in practice.

Speed matters too. If you need funds within two to three weeks — for an auction purchase deposit, an urgent repair, or a time-sensitive opportunity — a secured loan is likely your only realistic option. Remortgages simply take longer, and there’s no reliable way to rush the process.
