A second charge mortgage is a regulated UK loan secured against your home that sits behind your existing main mortgage at HM Land Registry. The "second charge" refers to its position in the priority order: if the property is ever sold to settle debts, the first-charge mortgage is paid in full before the second-charge lender receives anything. Borrowers typically use a second charge mortgage to release equity from their home without having to remortgage the whole property, which is useful when the existing first mortgage is on a low fixed rate that would be expensive to break.

TL;DR What it is: a regulated mortgage secured against a home that already has a first-charge mortgage on it. How it sits: behind the first mortgage in the priority order at HM Land Registry; the first-charge lender is paid first in any sale or repossession. Why people use it: to release equity without disturbing a low-rate first mortgage, to consolidate debt, or to fund home improvements. Who regulates it: the Financial Conduct Authority, under the same rules as a first-charge mortgage. |
How "first charge" and "second charge" work
Every mortgage is registered as a "charge" against the property at HM Land Registry. The charge gives the lender the legal right to apply to the court for possession and sale of the property if the loan is not repaid, and to take what they are owed from the sale proceeds before any other creditor.
The order in which charges are registered is called the priority order. The first lender to register a charge holds the "first charge" position; any later lender holds a "second", "third", or further charge position. The legal framework is set out in the Land Registration Act 2002, available at legislation.gov.uk.
If a property is sold to settle debts, proceeds are paid out in priority order:
- First-charge mortgage paid in full.
- Second-charge mortgage paid in full from any remaining proceeds.
- Third-charge or any later charges paid from whatever is still left.
- Any surplus returned to the borrower.
This order is what makes a second charge mortgage riskier for the lender: in a forced sale where prices are weak, the second-charge lender may not recover the full balance. This is why second charges typically carry slightly higher interest rates than first-charge mortgages.
Why people take a second charge instead of remortgaging
The most common reason a UK borrower chooses a second charge over a remortgage is because their existing first-charge mortgage is on a fixed rate that would be expensive to break. Modern fixed-rate UK mortgages typically carry early repayment charges (ERCs) of 1 to 5 percent of the outstanding balance during the fixed period. A borrower with £200,000 outstanding on a fixed rate three years from end of term might face an ERC of £8,000 to £10,000 to break the rate.
If the borrower needs to release £50,000 of equity for home improvements or debt consolidation, the maths often favours leaving the first mortgage alone and adding a second charge instead. The second charge carries a higher rate than the first mortgage, but it avoids the ERC and preserves the low-rate first mortgage. Comparison guidance is published by MoneyHelper, the government-backed money guidance service.
Regulatory status
Second charge mortgages on residential property in the UK are regulated by the Financial Conduct Authority. They have been regulated as mortgages (under MCOB) rather than as consumer credit (under the Consumer Credit Act) since 21 March 2016, following implementation of the Mortgage Credit Directive.
The conduct rules are the same as for first-charge mortgages, set out in FCA MCOB. They include:
- Affordability assessment. The lender must assess whether the borrower can afford the new monthly payment alongside existing committed expenditure.
- Stress testing. The affordability calculation includes a stress test at a higher rate than the one initially offered.
- Disclosure requirements. The lender must provide a European Standardised Information Sheet (ESIS) showing all costs, fees, and the total amount payable.
- A reflection period. The borrower has at least seven days to consider the offer before accepting.
All FCA-authorised second charge lenders and brokers are listed on the FCA Register. Always verify a lender or broker on the Register before instructing them.

Who offers second charge mortgages in the UK
Second charges are not typically offered by high-street banks. The market is served by specialist lenders such as Pepper Money, Selina Finance, United Trust Bank, Together Money, Norton Home Loans, Shawbrook Bank, and Equifinance, all FCA-authorised. Most applications go through specialist mortgage brokers who maintain relationships across the lender panel.
What a second charge does NOT do
A second charge mortgage is not the same as several other products that are sometimes confused with it.
| Product | How it differs from a second charge |
|---|---|
| Remortgage with capital raise | Replaces the first-charge mortgage with a larger one, instead of adding a second behind it |
| Further advance | A top-up of the existing first-charge mortgage from the same lender; does not create a second charge |
| Equity release / lifetime mortgage | Specialist product for over-55s where interest rolls up rather than being paid monthly; takes a first-charge position |
| Personal loan | Unsecured; not registered against the property; smaller amounts and shorter terms |
| Bridging loan | Short-term finance, often interest-only, usually 3 to 24 months; can take first or second charge depending on structure |
Risks borrowers should weigh
A second charge mortgage is secured against your home. If you fail to keep up repayments on either the first or the second charge, the lender can apply to the court for possession of the property. This is the same risk as on any mortgage, but it is worth restating because borrowers sometimes treat second charges as a lower-stakes form of borrowing than a "real" mortgage.
Other risks to weigh:
- Higher rates than first-charge mortgages. The rate difference compounds over the term and can be substantial.
- Longer terms increase total interest paid. Consolidating short-term debts into a 25-year second charge can lower the monthly payment but raises the total cost.
- ERCs on the second charge. Most products carry ERCs in the early years; if rates fall and you want to refinance, you may face a charge.
- Combined LTV exposure. A second charge taken at high combined LTV makes you more vulnerable to falling property prices, potentially leaving you in negative equity.
Borrowers benefit from the Financial Ombudsman Service for complaints (financial-ombudsman.org.uk) and the Financial Services Compensation Scheme for mis-selling claims against insolvent firms (fscs.org.uk).

Frequently asked questions
Is a second charge mortgage the same as a secured loan?
In modern UK regulation, yes. Since the Mortgage Credit Directive came into force on 21 March 2016, second charge loans on residential property have been regulated as mortgages by the FCA, eliminating the previous distinction between "secured loans" (regulated as consumer credit) and "second charge mortgages".
Can I have a second charge mortgage if I rent out my property?
Buy-to-let second charge mortgages exist but are usually unregulated, because they are commercial rather than residential lending. Specialist BTL second-charge lenders accept landlord applications, but the FCA's MCOB rules typically do not apply.
Does a second charge mortgage affect my main mortgage?
Not directly. The first-charge mortgage continues exactly as before. Indirectly, the second charge increases your total monthly mortgage commitment, which would affect any future remortgage or first-mortgage application.
Can I get a second charge mortgage with bad credit?
Yes, in many cases. Specialist lenders accept defaults, CCJs, and prior arrears at varying severity levels. Rates are higher and combined LTV is usually capped tighter than for clean-credit cases.
How much can I borrow on a second charge mortgage?
The limit is the lower of: the lender's maximum loan size (typically £500,000), the lender's combined LTV cap (typically 75 to 85 percent), and what the lender's affordability calculator allows given your income and committed expenditure. For most borrowers with reasonable equity, affordability is the binding constraint rather than LTV.
