What Is The Difference Between A First Charge And Second Charge Loan?

You can learn more about this type of borrowing on our secured loans against your property guide.

What is a First Charge loan?

A first charge loan is usually your main mortgage. When you buy a home and take out a mortgage, the lender places the first legal charge on your property. This gives them the primary right to be repaid if your home is sold, either voluntarily or through repossession.

If you default on repayments, the first charge lender is at the front of the queue, taking priority over all other creditors. This makes first charge loans relatively less risky for lenders, which is why they usually offer the lowest interest rates compared to other secured loans.

What is a Second Charge loan?

A second charge loan is an additional borrowing secured against your property, sitting behind your mortgage in priority. Because your mortgage lender must be repaid first, the second charge lender accepts more risk.

This type of loan is often used by homeowners who want to release equity without remortgaging. For example, if your mortgage has a competitive fixed rate you don’t want to lose, you might take a second charge loan to borrow extra funds while keeping your original mortgage in place.

How are repayments prioritised between First and Second Charge Loans?

If your home is repossessed, the proceeds from the sale go first to the first charge lender (your mortgage provider). Only once they have been repaid in full does the second charge lender receive what is left.

This repayment order explains why second charge loans typically come with higher interest rates than mortgages. Lenders are compensating for the added risk of being second in line.

How common are Second Charge Loans in the UK?

The UK’s second charge market has grown significantly in recent years. According to the Finance & Leasing Association, second charge mortgage new business grew by 14% year-on-year in 2023, with a value of around £1.6 billion. This growth reflects homeowners using equity release for debt consolidation, home improvements, or business purposes rather than switching their main mortgage.

Why would I choose a Second Charge Loan instead of remortgaging?

There are several reasons why a second charge loan might be chosen over remortgaging:

• Low-rate mortgage protection: If you’re on a long-term fixed rate, remortgaging could mean losing a great deal.
  
  
• Early repayment charges: Some mortgages have hefty penalties if repaid early.
  
  
• Credit profile changes: If your credit score has worsened since taking out your mortgage, remortgaging may not be cost-effective, making a second charge loan more practical.
  
  

In these cases, a second charge loan allows you to borrow extra without disrupting your main mortgage.

What risks come with Second Charge Loans?

The main risk is that your home remains at stake. Even if you keep up with mortgage payments, missing second charge loan repayments can still lead to repossession proceedings.

Another risk is affordability: because second charge loans usually have higher interest rates, they can be more expensive in the long run, especially if stretched over many years.

Finally, taking out additional secured debt reduces your equity, which can limit your options if house prices fall or if you need to remortgage in the future.

Are there differences in eligibility and checks for First and Second Charge Loans?

Yes. For both first and second charge loans, lenders will look at your income, credit history, and affordability. However, because second charge lenders are taking on more risk, they may have stricter affordability checks and sometimes higher rates.

Your loan-to-value (LTV) ratio also matters. Most lenders will only allow borrowing up to a certain percentage of your property’s value across both the first and second charges combined. According to Investopedia, this combined LTV ratio is typically capped at 80% of the property’s value.

Final thoughts: which option is right for me?

The key difference between first and second charge loans lies in priority of repayment: the first charge lender is always repaid first, while the second charge lender takes what is left.

For borrowers, this means first charge loans (mortgages) are cheaper and lower-risk, while second charge loans are more flexible but costlier and riskier.

If you’re considering borrowing, weigh up whether remortgaging, a second charge loan, or even an unsecured product is the right choice for your needs. Always compare options carefully and seek advice before putting your home on the line.
