Borrowing and credit
What is a remortgage?
Quick definition: A remortgage is the process of moving an existing mortgage to a new deal, either with the same lender or a different lender.
At a glance
- It often happens when a fixed or discount deal is ending.
- It can be used to change rate, term or lender.
- Fees, early repayment charges and affordability checks may apply.
- Borrowing more through a remortgage increases debt.
Explain it simply
Remortgaging means arranging a new mortgage deal for a property you already own or are already paying a mortgage on. People often remortgage when their current deal is ending, so they do not move onto a standard variable rate. They might stay with the same lender or move to a new one. A remortgage can save money, but fees, checks and early repayment charges matter. Borrowing extra money through a remortgage means taking on more debt.
Student explanation
Remortgaging is a common part of the UK mortgage lifecycle. It can involve a product transfer with the existing lender or a new mortgage with another lender. Reasons include securing a new rate, changing the mortgage term, switching repayment method or raising additional borrowing. Students should distinguish remortgaging from moving home: the property may stay the same while the mortgage changes. Total cost comparisons should include product fees, valuation, legal costs and any early repayment charges.
Professional explanation
A remortgage is replacement or refinancing of an existing mortgage, either internally through product transfer or externally through a new lender. The process involves eligibility, affordability, valuation, conveyancing where applicable, redemption, completion and registration steps. Customer outcomes depend on timing, reversion-rate avoidance, fee comparison, loan to value, credit profile and advice or execution-only pathways. Additional borrowing via remortgage requires clear affordability and purpose assessment. Remortgaging should be distinguished from a further advance, second charge mortgage and home mover mortgage.
UK example
A borrower with a five-year fixed-rate deal ending in three months compares remortgage options before the mortgage moves to SVR.
Why it matters
Remortgaging can affect monthly payments for years and is one of the main decision points in a mortgage.
Common misunderstanding
Remortgaging does not always mean changing lender; a new product with the same lender may also be an option.
