Remortgaging Guide UK
How to switch your mortgage and potentially reduce your monthly payments.
What Is Remortgaging?
Remortgaging means switching your existing mortgage to a new deal — either with your current lender or a new lender. Homeowners typically remortgage when their fixed-rate deal ends.
If you're still early in your property journey, it may help to read our Buying Guide to understand how mortgages fit into the wider process.
Why Do People Remortgage?
- To secure a better interest rate
- To reduce monthly payments
- To switch from variable to fixed rate
- To release equity from property
- To consolidate debt
When Is the Best Time to Remortgage?
Typically:
- 3–6 months before your current deal ends
- When property value increases
- When interest rates fall
How the Remortgaging Process Works
- Check your current mortgage terms
- Compare deals
- Apply for new mortgage
- Property valuation
- Legal transfer
- New mortgage begins
The legal side is handled through conveyancing — see our Conveyancing Guide for full details.
Remortgage Costs
- Arrangement fee
- Valuation fee

Some lenders offer fee-free remortgage packages.
What Is Equity Release?
If your property has increased in value, you may be able to borrow additional funds against it. This is known as releasing equity.
Common Uses:
- Home improvements
- Debt consolidation
- Investing in another property

How Property Value Affects Remortgaging
The lower your Loan-to-Value (LTV) ratio, the better the rates available.
Example:
- Home value: £300,000
- Mortgage remaining: £150,000
- LTV = 50%
