Second Charge Loans: What are they & when are they useful?
18 February 2026
A second charge loan, sometimes referred to as a second charge mortgage, is a type of secured borrowing that sits behind an existing first charge mortgage on a property. This article explains in detail what second charge loans are and when they may be useful.
For brokers navigating today’s complex lending environment, understanding the options available to clients is essential. As high-street lenders tighten criteria, and with ongoing rate fluctuations, more borrowers are looking beyond traditional remortgaging to raise capital.
Second charge loans are becoming increasingly popular for clients seeking additional funds without disturbing their existing mortgage.
Read on as we explain what a second charge loan is, how it works and when it may be the most appropriate option to deliver the best possible outcome for your clients.
What is a Second Charge Loan?
A second charge loan, sometimes referred to as a second charge mortgage, is a type of secured borrowing that sits behind an existing first charge mortgage on a property.
To simplify it, it allows borrowers to take out additional finance secured against their home without replacing or refinancing their current mortgage.
How Does Borrowing Against Property Work?
Many homeowners build up significant equity over time, either through capital repayment or house price growth. Borrowing against property allows homeowners to unlock some of that value without remortgaging or reselling.
With a second charge loan:
The client retains their existing mortgage
A new loan is secured against the same property
The borrower makes a separate monthly repayment to the second charge lender
For brokers, this structure can be a great option when refinancing a clients first mortgage would not be cost-effective or feasible.
When Should a Second Charge Loan be Considered?
There are several scenarios where a second charge loan may be more appropriate than a remortgage.
Early Repayment Charges (ERCs)
If a client is locked into a competitive fixed rate with high ERCs, refinancing the entire mortgage could be expensive. A second charge loan allows them to raise additional funds without facing ERCs.
Low Existing Interest Rates
Many borrowers may have secured low fixed rates in recent years. Replacing that rate with a higher one, simply to raise capital can significantly increase monthly repayments.
Complex Income or Criteria Issues
Some high street lenders have tightened affordability assessments. Where a further advance or remortgage is declined by a clients first lender, specialist second charge lenders can offer greater flexibility, particularly for clients who are self-employed, have a complex income structure or adverse credit.
Common Uses for Second Charge Loans
Understanding when to use a second charge is essential when structuring your client’s case.
Debt Consolidation
One of the most common reasons a second charge loan is used is to consolidate debt. Consolidating multiple debts into one facility can reduce monthly outgoings, depending on the clients’ circumstances.
Home Improvements
Clients looking to fund extensions, renovations or other home upgrades might opt for a second charge loan rather than refinancing their first mortgage.
Business Purposes
Where capital is needed for business investment, expansion or cash flow, a second charge loan can provide a practical funding route.
Tax Liabilities
Capital raising for tax payments is another area where secured borrowing can be useful.
Second Charge Loan Eligibility
Second charge loan eligibility will vary depending on the lender, but generally lenders will look at the following.
Available Equity
Loan-to-value (LTV) limits across both charges combined. The higher the remaining equity, the stronger the proposition.
Affordability
Full affordability assessments are required, considering:
Income (employed, self-employed, or other income streams)
Existing mortgage commitments
Unsecured debt
Household expenditure

Advantages of Second Charge Loans for Brokers
Second charge loans offer brokers a valuable additional tool when structuring cases.
Expanding Your Advice Proposition
Offering secured loans to your clients alongside traditional mortgage solutions broadens your service proposition.
Supporting Complex Cases
Second charge lenders often operate with a more manual underwriting approach, allowing for common sense decisions where automated systems may decline.
Faster Access to Funds
In some scenarios, second charge loans can be processed more quickly than a full remortgage, allowing you to provide quick solutions to your clients.
Things to Consider
While a second charge loan can be a valuable tool, they are not suitable in every scenario. Before suggesting a second charge as a solution for your clients, it is important to consider the following.
The total cost over the full term
The impact of extending secured borrowing
Any early repayment charges on the second charge
Client understanding of secured versus unsecured borrowing
The objective is not simply to raise capital, but to structure borrowing in a way that aligns with the client’s long-term financial position.
The Growing Role of Second Charges
Second charges are no longer a niche product solely for adverse credit scenarios. They are a regulated, mainstream funding solution that can protect existing mortgage rates, offer flexible underwriting and support complex income structures.
As affordability pressures and stricter criteria continue to evolve, brokers who understand when to utilise second charge lending are better positioned to deliver tailored client solutions.
For many borrowers, particularly those who are reluctant to disturb a first charge mortgage, the client’s question is no longer “can we remortgage?” but instead “what is the most appropriate option for us?”
