The short answer
What is debt consolidation with a second charge?
A second charge can combine eligible debts into a new loan secured on your home while the first mortgage remains in place. You continue to have the first-mortgage payment and the new second-charge payment.4
It may reduce the number or amount of monthly payments, but that is not the same as reducing the total cost. Repaying over longer can cost more, fees can increase the secured balance, and debts that were unsecured become secured against the home.41
FCA mortgage advice rules require relevant consideration of the longer repayment period, whether securing previously unsecured borrowing is appropriate and, where payment difficulties are known, whether an arrangement with creditors may be more appropriate.3
The FCA's March 2026 review found that standards of second-charge advice could be improved, particularly for debt consolidation. It highlighted cases where eligibility was prioritised over suitability, alternatives were not adequately considered, or monthly-payment reductions were emphasised without the total-cost trade-offs.12
Step 1 · Understand the structure
What debt consolidation with a second charge actually changes
A second charge normally sits behind the existing first mortgage rather than replacing it. The agreed balances are repaid from the new borrowing, while the first mortgage continues and a separate second secured payment begins.
Credit card
Personal loan
Other eligible debt
Subject to the recommended loan and completion arrangements.
01 First charge mortgage remains
02 New second charge mortgage
Step 2 · Understand the cause
Begin with the budget, not the available equity
Establish whether the balances followed a one-off event or reflect a recurring gap between income and normal spending. Consolidation changes the structure of debt; it does not remove the reason it accumulated.
Understand why the balances arose
A one-off event still needs evidence, a resilient future budget and a complete comparison before secured borrowing is considered.
Pause before adding secured debt
Explore creditor support and free debt advice. A new loan does not remove the underlying deficit and could place the home at risk.
This is a discussion framework, not a suitability test or recommendation.
Step 3 · Verify every balance
Create a complete record before comparing anything
Estimates can hide expensive or nearly repaid accounts. Use current statements and settlement figures so every balance can be considered on its own facts.
Current settlement figure
Rate or APR and any charge
Payment and remaining term
Up to date, arrears or arrangement
Record why each debt is included or deliberately left outside the proposed consolidation.
Step 4 · Compare the complete outcome
Monthly payment is only one line of the comparison
A longer mortgage term can reduce the immediate payment while increasing the time in debt and total interest. Fees may also be added to the new secured balance and attract interest over the term.
What it costs to clear them now
- Verified settlement balances
- Current interest and remaining terms
- Any settlement charges
- Existing debts are generally unsecured
What the new commitment costs
- Loan amount including any added fees
- APRC, payment and proposed term
- Total amount payable and ERCs
- Previously unsecured debt is secured on the home
Read the written recommendation carefully
The trade-offs should be clear before any decision
The comparison should explain why each debt is included and why the proposed term is appropriate.- Check APRC, fees, ERCs and total amount payable.
- Consider both the first and second mortgage payments.
- Allow time to understand the alternatives and secured risk.
Step 5 · Consider alternatives
Secured borrowing should not close down other options
Where payments are already difficult, contacting creditors and obtaining free debt advice may be more appropriate than taking new secured borrowing. Formal debt solutions require specialist debt advice.
Creditor support and free debt guidance
If payments are difficult, contact creditors early and use MoneyHelper to find free debt advice before taking new secured borrowing.
Unsecured consolidation
Where affordable and available, compare an unsecured loan or balance transfer on fees, promotional end dates and total cost without securing the new debt on the home.
Further advance or remortgage
Apply the same term and secured-debt warnings, and include the effect on the whole first mortgage when comparing a remortgage.
Step 6 · Test suitability and affordability
The future household budget must remain realistic
Eligibility is not suitability. A recommendation needs verified debt data, a sustainable post-consolidation budget and a clear reason for securing each included balance.
- The cause of the balances is understood and the future household budget is sustainable.
- Every balance, rate, payment, remaining term and settlement cost is verified.
- The borrower understands the longer-term cost and the consequence of securing the debts.
- Creditor support, free debt guidance and relevant unsecured and mortgage alternatives have been considered.
Step 7 · Prepare the evidence
Information needed for a responsible review
- Current statements and settlement figures for every debt considered
- Rates or APRs, payments, remaining terms and any settlement charges
- First-mortgage statement, product terms and current payment
- Income evidence and realistic household expenditure
- Recent bank statements and details of arrears or payment arrangements
Step 8 · Document the reasoning
What the advice process should establish
- 01
Understand the cause
Identify whether balances grew after a one-off event or because normal income no longer covers realistic expenditure.
- 02
Verify every debt
Collect current balances, payments, rates or APRs, remaining terms, settlement costs and payment status.
- 03
Compare complete outcomes
Set current settlement costs beside the second charge's fees, APRC, term, both secured payments and total payable.
- 04
Test life after consolidation
Confirm the budget remains sustainable and discuss how repaid credit accounts and future borrowing will be handled.
The complete decision
Four considerations that remain connected
Root cause
Consolidation does not repair an ongoing deficit between household income and normal expenditure.
Verified current cost
Balances, contractual payments, rates, terms and settlement charges are needed for a meaningful comparison.
New term and total payable
A payment reduction can result from taking longer to repay and may increase the total cost.
Security and resilience
Previously unsecured debt becomes secured on the home, so both mortgage payments need a resilient budget.
Illustrative decision method
Compare verified debts with the complete secured proposal
A homeowner asks about consolidating a personal loan and two credit-card balances. The adviser records a current settlement figure, rate or APR, payment and remaining term for every account, alongside the household's full income and realistic expenditure.
- 1Compare current settlement costs with the new amount including fees, APRC, term and total payable.
- 2Explain why each balance is included and why the proposed term is appropriate.
- 3Consider creditor arrangements, free debt advice and unsecured options before any recommendation.
FAQs
Debt consolidation questions
Not necessarily. A lower monthly payment can come from a longer term, and total repayment may increase after interest and fees. Compare verified current costs with the proposed illustration.
