Second Charge Mortgage Guide | Everything You Need to Know. Are you considering borrowing more money but don’t want to give up your current mortgage deal? A second charge mortgage, also known as a second mortgage or secured loan, could be the solution.
With rising interest rates and homeowners often locked into competitive fixed-rate deals, many people are turning to second charge mortgages as a way to access extra funds without disturbing their existing mortgage. Whether you’re looking to consolidate debt, fund home improvements, invest in a buy-to-let property, or cover a major expense, a second charge mortgage allows you to release equity while keeping your original mortgage in place.
In this guide, we’ll explain exactly how second charge mortgages work, the key benefits and risks, who they’re suitable for, and the steps you’ll need to take to apply. By the end, you’ll have a clear understanding of whether a second charge mortgage is the right financial move for you.
What Is a Second Charge Mortgage?
A Second Charge Mortgage is a type of secured loan that is taken out in addition to your existing mortgage. It allows you to borrow money against the equity you have built up in your home, without replacing your current mortgage.
Your first mortgage remains in place, and the second charge sits behind it, hence the name “second charge”. If you sold your home, the first mortgage would be repaid first, and the second charge loan would be repaid after that.
How Does It Work?
When you apply for a second charge mortgage, a lender assesses the amount of equity in your property. Equity is the difference between your property’s current value and what you still owe on your mortgage.
For example:
Home value: £300,000
Outstanding mortgage: £200,000
Equity available: £100,000
You may be able to borrow a portion of that £100,000 equity through a second charge loan, depending on your income, credit profile, and lender criteria.
When Should You Choose a Second Charge Mortgage Instead of Remortgaging?
Choosing a second charge mortgage could be the better option if:
| Scenario | Second Charge Mortgage | Remortgaging |
|---|---|---|
| You’re on a low fixed rate and don’t want to lose it | ✅ Ideal – lets you borrow more without changing your current deal | ❌ Not ideal – remortgaging would replace your low rate |
| Your current mortgage has early repayment charges (ERCs) | ✅ Avoids ERCs by leaving the first mortgage untouched | ❌ May trigger expensive ERCs if you remortgage |
| You’ve had a change in credit score or circumstances | ✅ May still be accepted as second charge lenders are more flexible | ❌ Could result in a worse deal overall if your credit has dropped |
| You only need to borrow a specific amount | ✅ Only borrow what you need, separately from your main mortgage | ❌ You’d need to refinance the entire mortgage, which may not be efficient |
| You’re self-employed or have complex income | ✅ More specialist lenders available with flexible underwriting | ❌ May struggle to meet standard mortgage criteria |
| Your current lender won’t offer additional borrowing | ✅ Gives you an alternative way to access equity | ❌ You’re limited to your current lender’s offering or must switch completely |
| You need funds quickly | ✅ Often faster to arrange than full remortgaging | ❌ Can take longer due to full remortgage process |
| You want to consolidate debt separately from your main mortgage | ✅ Keeps debt consolidation separate, with a clear repayment structure | ❌ May extend the debt over the full mortgage term, costing more overall |
What’s the Difference Between a Second Charge Mortgage and Remortgaging?
| Feature | Second Charge Mortgage | Remortgaging |
|---|---|---|
| Replaces existing mortgage? | No, it’s in addition | Yes, replaces current mortgage |
| Good if you’re on a good deal with your current lender? | ✅ Yes | ❌ Not ideal if early repayment charges apply |
| Useful if you have poor credit now but didn’t when you got your first mortgage? | ✅ Yes | ❌ May end up on worse terms overall |
| Flexibility for complex income or self-employed? | ✅ Often more flexible | ❌ May be harder with mainstream lenders |
| Access to equity without affecting first mortgage? | ✅ Yes | ❌ Not possible, as you refinance everything |
In Summary:
-
Second charge mortgages are ideal if you want to borrow more without disturbing your current mortgage.
-
Remortgaging may be better if you’re coming to the end of your deal and can get a good new rate.
When Should You Choose a Second Charge Mortgage Instead of Remortgaging?
Making the right choice between remortgaging and taking out a second charge mortgage can have a big impact on your finances. Both options allow homeowners to release equity from their property, but they work in different ways and suit different circumstances.
Below, we explore when a second charge mortgage might be the smarter alternative to remortgaging.
Understanding the Difference
Remortgaging replaces your existing mortgage with a new one, often to secure a better rate or release funds.
A second charge mortgage, however, runs alongside your current deal; it’s a separate loan secured on the same property. This means you’ll have two repayments: one for your main mortgage and another for your second charge.
When a Second Charge Mortgage May Be Better
1. You Have a Competitive Fixed Rate on Your Main Mortgage
If your existing mortgage rate is significantly lower than current market rates, remortgaging could mean losing that benefit. A second charge mortgage allows you to borrow extra funds without disturbing your main deal, protecting your low rate.
2. Early Repayment Charges Would Be High
Many fixed-rate mortgages have early repayment charges (ERCs) that can reach thousands of pounds. Instead of paying those penalties, a second charge lets you access funds without breaking your existing mortgage terms.
3. You Need Funds Quickly
Second charge mortgages can often be arranged more quickly than a full remortgage, making them a suitable solution for urgent financial needs, such as home improvements, debt consolidation, or funding business projects.
4. You Have Recently Become Self-Employed or Your Income Has Changed
If your income has changed and your new affordability profile no longer fits a lender’s remortgage criteria, a second charge mortgage might still be available. Lenders in this market can be more flexible when assessing income types and credit history.
5. You Have Adverse Credit but Strong Equity
If your credit score has dropped since your last mortgage, remortgaging could result in your entire balance being transferred to a higher rate. A second charge allows you to keep your main mortgage untouched and borrow separately, often at a better combined cost.
6. You Need to Borrow for a Specific Purpose
Second charge mortgages can be used for a variety of reasons, including:
Home extensions or renovations
Debt consolidation
School or university fees
Investing in a business
They give you flexibility to use your home’s equity strategically while keeping your main mortgage intact.
When Remortgaging May Be Better
Remortgaging might make more sense if:
You’re at the end of a fixed term
Your current rate is high
You want to consolidate multiple debts into one loan
You prefer a single repayment with one lender
In these cases, replacing your main mortgage could result in a lower overall interest rate.
The Bottom Line
A second charge mortgage is a powerful financial tool when used in the right situation — particularly if you have a great main mortgage deal, high ERCs, or non-standard income.
Before making a decision, it’s essential to speak with a qualified mortgage adviser who can assess your full financial picture and help you choose the most cost-effective path.
Pros and Cons at a Glance
| Pros | Cons |
|---|
| ✅ Keep your existing mortgage deal – You don’t need to disturb a low interest rate or pay early repayment charges on your current mortgage. | ❌ Two mortgage payments – You’ll have to manage two monthly payments: your original mortgage and the second charge loan. |
| ✅ Access equity without remortgaging – Ideal if your current lender won’t offer further borrowing or if remortgaging isn’t suitable. | ❌ Your home is at risk – Like any secured loan, your property could be repossessed if you fail to repay. |
| ✅ Flexible lending criteria – Second charge lenders often consider complex income, self-employed, or credit-impaired applicants. | ❌ Higher interest rates – Second charge loans can carry higher rates than first mortgages, depending on your credit profile. |
| ✅ Useful for large or specific borrowing needs – Perfect for home improvements, debt consolidation, or school fees. | ❌ Long-term cost – If borrowed over a long term, the total interest paid could be high. |
| ✅ Faster approval in some cases – Often a quicker route than remortgaging, especially if time-sensitive. | ❌ Added complexity – More paperwork and legal checks are involved, and not all brokers advise on them. |
