Second Charge Mortgage Fees and Costs: Second charge mortgage costs can include interest, lender fees, adviser charges, valuation costs and legal expenses.
Some fees may be added to the loan. However, this means interest could be charged on them.
Compare the APRC, loan term and total amount repayable. Do not judge a second charge mortgage using the monthly payment alone.
What Does a Second Charge Mortgage Cost?
A second charge mortgage is a separate loan secured against a property that already has a mortgage.
The first mortgage remains in place. The homeowner therefore has two secured borrowing commitments.
The cost of a second charge mortgage usually depends on:
- The amount borrowed.
- The interest rate.
- The repayment method.
- The loan term.
- The combined loan-to-value.
- The applicant’s credit position.
- Lender and adviser fees.
- Valuation and legal costs.
- Early repayment conditions.
A lower monthly payment does not always mean lower borrowing costs.
Spreading a loan over a longer period may reduce the monthly payment. However, it can increase the total interest paid.
Our guide to second charge mortgages explains how the product works alongside an existing mortgage.
Which Second Charge Mortgage Fees May Apply?
Fees vary between lenders, advisers and individual applications.
The main costs may include:
- Lender arrangement fees.
- Adviser or broker fees.
- Property valuation fees.
- Legal fees.
- Administration charges.
- Funds transfer fees.
- First mortgage lender consent charges.
- Early repayment charges.
- Exit or closure fees.
Not every application will include every fee.
Before proceeding, request a clear breakdown showing which fees apply and when they become payable.
What Is a Lender Arrangement Fee?
A lender arrangement fee covers part of the cost of setting up the loan.
It may be:
- A fixed amount.
- A percentage of the loan.
- Paid before completion.
- Deducted from the funds.
- Added to the mortgage balance.
A percentage-based fee becomes more expensive as the loan amount increases.
For example, a 2% fee would equal:
| Loan amount | 2% arrangement fee |
|---|---|
| £25,000 | £500 |
| £50,000 | £1,000 |
| £75,000 | £1,500 |
| £100,000 | £2,000 |
These figures are examples rather than current lender charges.
The exact fee must be confirmed within the mortgage illustration and offer.
Can Fees Be Added to the Loan?
Some lenders allow certain fees to be added to the loan balance.
This may reduce the amount needed upfront. However, it usually increases the total amount repayable.
Consider a homeowner who requires £40,000.
If £2,000 of fees are added, the starting loan balance becomes £42,000.
Interest may then be charged on the additional £2,000 throughout the term.
The practical question is not only whether a fee can be added.
The borrower should also ask:
- How much interest will the fee attract?
- Will adding it increase the monthly payment?
- Does it affect the loan-to-value?
- Can it be paid upfront instead?
- Will the fee be refunded if the application fails?
The mortgage illustration should explain the effect of adding fees.
How Much Can Adviser or Broker Fees Cost?
An adviser may charge for researching, recommending and arranging a second charge mortgage.
The fee could be:
- A fixed amount.
- A percentage of the loan.
- Payable on application.
- Payable when an offer is issued.
- Payable only when the loan completes.
The adviser should explain the charge before providing a regulated service.
The agreement should also explain whether the fee remains payable if the application is not completed.
The FCA reviewed intermediary fees within the second charge mortgage market during 2026. Its findings emphasised the need for firms to consider fair value and customer outcomes.
Read the FCA findings on second charge mortgages for regulatory information.
Will You Need to Pay a Valuation Fee?
The second charge lender must assess the property used as security.
It may use:
- An automated valuation.
- A desktop valuation.
- A drive-by assessment.
- A physical inspection.
- A detailed property report.
The valuation method often depends on the property, loan amount and combined loan-to-value.
Some lenders include a basic valuation without a separate charge.
Others may charge the applicant directly.
A specialist property, unusual construction or higher loan amount could require a more detailed assessment.
The lender’s valuation is completed for lending purposes. It is not the same as a structural survey for the homeowner.
Can Legal Fees Apply?
Legal work may be needed to register the second charge against the property.
The process can include:
- Reviewing the property title.
- Confirming existing secured borrowing.
- Obtaining consent from the first lender.
- Preparing mortgage documents.
- Registering the new charge.
- Completing redemption work where debts are repaid.
Some lenders use their own legal process.
Others may require the homeowner to appoint a solicitor.
The quotation should explain whether legal costs are included or charged separately.
Complex title arrangements may increase the work required.
Examples include:
- Leasehold properties.
- Shared ownership.
- Restrictions on the title.
- Existing secured debts.
- Matrimonial notices.
- Properties held in trust.
- Changes in property ownership.
Does the First Mortgage Lender Charge a Fee?
The first mortgage lender may need to consent to the second charge.
This is sometimes called consent to a subsequent charge.
The lender could charge an administration fee for reviewing the request.
Consent is not automatic.
The first lender may examine:
- The proposed second charge amount.
- The reason for borrowing.
- Current mortgage conduct.
- The remaining property equity.
- The new lender’s legal requirements.
Ask whether consent is needed before paying non-refundable application costs.
How Is Second Charge Mortgage Interest Calculated?
Interest is charged on the outstanding second charge balance.
The rate may be:
- Fixed for an agreed period.
- Variable.
- Linked to a lender’s variable rate.
- Set for the full mortgage term.
A fixed rate can provide payment certainty during the fixed period.
A variable rate may change. This means the monthly payment and total cost could increase or decrease.
The lender should explain:
- The initial interest rate.
- How long that rate applies.
- What happens afterwards.
- When a variable rate may change.
- How payment changes will be communicated.
The rate should not be considered separately from the fees and term.
What Is APRC?
APRC means annual percentage rate of charge.
It is designed to show the annual cost of mortgage borrowing using a standardised calculation.
The APRC can include:
- Interest.
- Certain lender fees.
- Compulsory charges.
- Expected rate changes.
- Costs linked to the mortgage agreement.
APRC can help compare products. However, it is based on assumptions.
The actual cost may differ if:
- The mortgage is repaid early.
- Interest rates change differently.
- Optional fees apply.
- The borrower makes overpayments.
- The loan does not continue for the full term.
Compare APRC alongside the actual rate, fees and total repayment figure.
Why Does the Loan Term Matter?
The loan term is one of the biggest influences on total borrowing costs.
A longer term normally creates smaller monthly payments.
However, the borrower may pay interest for more years.
The simplified example below shows how the same loan can produce different outcomes.
| Example | Shorter term | Longer term |
|---|---|---|
| Amount borrowed | £40,000 | £40,000 |
| Illustrative rate | 8% | 8% |
| Term | 10 years | 20 years |
| Approximate monthly payment | £485 | £335 |
| Approximate total repayment | £58,200 | £80,400 |
These figures are approximate repayment examples. They exclude fees and do not represent a current product.
The longer term lowers the example payment by around £150 each month.
However, the total repayment increases by more than £22,000.
Affordability matters. Total cost matters too.
What Is the Total Amount Repayable?
The total amount repayable estimates how much the borrower may pay over the full loan term.
It can include:
- The original loan.
- Interest across the term.
- Fees added to the balance.
- Certain compulsory charges.
This figure can provide more context than the monthly payment.
Suppose two products offer similar monthly repayments.
One may involve:
- A longer term.
- A higher arrangement fee.
- A variable rate.
- More interest over time.
- Restrictive early repayment conditions.
The other may have a higher initial payment but lower overall costs.
The right comparison should reflect both affordability and long-term value.
Do Early Repayment Charges Apply?
Some second charge mortgages include early repayment charges.
These may apply when the borrower:
- Repays the loan early.
- Remortgages the property.
- Sells the home.
- Makes an overpayment above the permitted limit.
- Refinances with another lender.
The charge could be:
- A percentage of the outstanding balance.
- A fixed number of months’ interest.
- A reducing percentage over time.
- A fixed administration amount.
Review the early repayment rules before completing.
This is particularly important when you expect to move or remortgage soon.
Can Overpayments Reduce the Cost?
Some lenders allow regular or occasional overpayments.
An overpayment could:
- Reduce the outstanding balance.
- Lower future interest.
- Shorten the mortgage term.
- Create repayment flexibility.
Limits may apply.
Exceeding the permitted allowance could trigger a charge.
The effect also depends on how the lender applies the payment.
Ask whether an overpayment:
- Reduces the term.
- Reduces the monthly payment.
- Is applied immediately.
- Requires prior notice.
- Attracts an administration fee.
The mortgage agreement should explain the available options.
Is a Second Charge Cheaper Than Remortgaging?
A second charge mortgage may allow a homeowner to retain an existing mortgage deal.
This can be useful when the first mortgage has:
- A competitive fixed rate.
- A significant early repayment charge.
- A long remaining fixed period.
- Terms worth retaining.
However, the second charge rate may be higher than the first mortgage rate.
There may also be two sets of payments and separate product terms.
A remortgage could replace the full mortgage balance and release additional funds.
It may produce a lower rate on the new borrowing. Yet it could increase the rate paid on the existing balance.
Our remortgage or second charge comparison explains the practical differences.
What About a Further Advance?
A further advance involves borrowing more from the current mortgage lender.
It normally sits alongside the original mortgage account.
The current lender will reassess affordability and apply its available product criteria.
A further advance may involve fewer legal steps. However, it is not automatically cheaper.
Compare:
| Cost consideration | Further advance | Second charge |
|---|---|---|
| Existing mortgage remains | Usually | Yes |
| New lender required | No | Usually |
| Separate interest rate | Often | Yes |
| Valuation may apply | Possibly | Possibly |
| Legal work may apply | Limited or none | May apply |
| Existing lender criteria | Required | First lender consent may be required |
| Adviser fee | May apply | May apply |
The best route depends on rates, fees, eligibility and the total amount repayable.
How Can Debt Consolidation Affect the Total Cost?
A second charge mortgage may be used to repay unsecured borrowing.
This can include credit cards or personal loans.
Combining several debts could reduce the immediate monthly outgoings.
However, a lower payment does not always mean a saving.
For example, a short-term personal loan may have only three years remaining.
Moving that balance into a 15-year second charge could increase the total interest.
The borrowing would also become secured against the property.
Before consolidating debts, compare:
- The existing debt balances.
- Current monthly payments.
- Remaining debt terms.
- Existing interest costs.
- The proposed secured term.
- New mortgage fees.
- Total repayment under both routes.
The purpose should be to improve the overall financial position, not only the next monthly payment.
Which Costs Should You Compare?
Before choosing a product, review the following figures:
Initial costs
- Adviser fee.
- Lender arrangement fee.
- Valuation charge.
- Legal costs.
- Administration fees.
Monthly costs
- Initial monthly payment.
- Payment after any fixed period.
- First mortgage payment.
- Related insurance costs.
Long-term costs

- Interest across the full term.
- Cost of fees added to the loan.
- Potential variable rate increases.
- Early repayment charges.
Practical costs
- Delays caused by missing documents.
- First lender consent.
- Property title complications.
- Cost of changing the loan later.
- Effect on a future remortgage.
A detailed comparison should include all four areas.
Questions to Ask Before Paying a Fee
Ask the adviser or lender:
- What is the exact fee?
- When does it become payable?
- Is it fixed or percentage-based?
- Is it refundable?
- Can it be added to the loan?
- How much interest would that add?
- Are legal and valuation costs included?
- Does the first lender charge for consent?
- Are there early repayment charges?
- What is the total amount repayable?
Clear answers allow a more accurate comparison.
How Can You Keep Second Charge Costs Under Control?
Start by deciding how much you genuinely need to borrow.
Borrowing more than required increases interest and may affect the loan-to-value.
You can also:
- Compare several product structures.
- Review different loan terms.
- Consider paying fees upfront.
- Check permitted overpayments.
- Avoid unnecessary optional charges.
- Prepare documents before applying.
- Compare remortgage and further advance options.
- Review the total amount repayable.
A second charge mortgage adviser can compare criteria and product costs.
Advice does not remove the cost of borrowing. It should help make those costs clearer.
Second Charge Borrowing for Older Homeowners
Age, retirement income and the proposed term may affect available options.
A standard second charge mortgage normally requires regular monthly payments.
Applicants approaching retirement may need to show how payments will remain affordable.
Alternative later-life products may use different repayment structures and eligibility assessments.
The Connect Lifetime second charge mortgage guide provides further information for older homeowners.
Products should be compared carefully because their long-term effects can differ considerably.

Second Charge Mortgage Fees FAQs
How much are second charge mortgage fees?
Fees vary between lenders and advisers. They may include arrangement, advice, valuation, legal and administration charges.
Can second charge mortgage fees be added to the loan?
Some fees can be added to the loan. Interest may then be charged on those fees throughout the term.
Do second charge mortgages have valuation fees?
A valuation is normally required. The lender may cover the cost or charge the applicant, depending on its policy.
Are legal fees always required?
Legal work may be required to register the charge. Some lenders include these costs, while others charge them separately.
What does APRC mean?
APRC is the annual percentage rate of charge. It estimates the annual borrowing cost using interest and certain compulsory fees.
Why is the total amount repayable important?
It shows the estimated overall cost across the term. This can reveal the effect of interest, fees and longer repayment periods.
Can I repay a second charge mortgage early?
Usually, yes. However, an early repayment charge or administration fee may apply.
Is a lower monthly payment always better?
No. A lower payment may result from a longer term, which can increase the total interest paid.
Are adviser fees refundable?
This depends on the adviser’s terms. Confirm when the fee becomes payable and whether any part is refundable.
Is a second charge cheaper than a remortgage?
Not automatically. Compare interest rates, fees, early repayment charges, loan terms and total repayment under both options.
Your home may be repossessed if you do not keep up repayments on your mortgage or another loan secured against it.
