What is the difference between a first and second charge mortgage?
A first charge mortgage is the main loan secured on a property and has first claim on sale proceeds. A second charge mortgage is an additional loan secured on the same property, behind the first charge in priority. Both require separate repayments, and both put the property at risk if payments are not maintained.
The table below summarises the main points of comparison. Individual products can vary, so the relevant mortgage illustration and offer are the documents that confirm the exact terms.

More detail on how a second charge sits alongside an existing mortgage is set out on the second charge mortgages hub.
How does charge priority work if a property is sold?
Charge priority describes the order in which secured lenders are paid from sale proceeds. The first charge lender normally has priority, with a second charge lender behind it. Priority does not remove either borrower obligation: a second charge remains secured on the property and its repayment terms continue to apply.
Charges are usually registered in the order they were created, and that registered order generally determines the sequence of repayment from any sale proceeds. This is a general priority principle rather than a description of how any individual case will resolve. Anyone concerned about affordability or missed payments can read the second mortgage risks guide for further context.
When might a second charge be considered instead of remortgaging?
A second charge can be compared with remortgaging when someone wants additional borrowing while keeping an existing first mortgage in place. The comparison involves more than the headline rate: the existing mortgage's early repayment charge, both products' fees, monthly payments, loan terms and total cost all affect the outcome.
Remortgaging replaces the whole of the existing borrowing, while a second charge leaves the first mortgage untouched and adds a further secured loan behind it. Neither route is inherently cheaper or more suitable; the comparison depends on rates, fees, terms and the total amount repayable. The dedicated comparison page sets out second charge mortgage vs remortgage in more depth, alongside second charge mortgage rates and costs.
What are the key risks of a second charge mortgage?
A second charge mortgage adds a further secured repayment to the existing mortgage. The overall cost can be affected by the rate, fees and term, and missing payments can have serious consequences. As with other borrowing secured on a home, the property may be at risk of repossession if repayments are not maintained.
Points worth reviewing before comparing offers:
- Two separate secured repayments to maintain each month
- The total cost, including fees, not only the interest rate
- Any early repayment charge on either the first or second charge
- The consequences of missing payments on secured borrowing

Frequently asked questions
Is a second charge mortgage the same as a second mortgage?
The terms are commonly used interchangeably in the UK to describe borrowing secured on a home that already has a first mortgage. The exact product, rate structure and terms depend on the individual agreement and the lender involved, so the mortgage illustration and offer documents remain the definitive description of any particular arrangement.
Does a second charge mortgage replace the first mortgage?
No. A second charge mortgage is additional borrowing that normally runs alongside an existing first mortgage rather than replacing it. Both agreements continue separately, each with its own repayment schedule, so a borrower manages two secured commitments rather than one combined mortgage after a second charge completes.
Can the first mortgage lender be paid before a second charge lender?
Charge priority generally means a first mortgage lender is repaid before a second charge lender from sale proceeds. This ranking principle does not predict an individual outcome or remove either lender's rights under its agreement. The specific position depends on the registered charges and the circumstances of the sale.
What is the difference between a second charge mortgage and a remortgage?
A second charge mortgage adds a separate loan alongside an existing first mortgage, which stays in place. A remortgage replaces the existing mortgage with a new one, often with a different lender. Each route can involve different fees, rates, terms and early repayment charges that need individual comparison.
