Second Charge Mortgages: Raising Capital Without Remortgaging
If you have equity in a property but don't want to disturb an existing low-rate first charge, a second charge mortgage allows you to borrow against that equity as a separate facility — leaving your first mortgage untouched.
In a rising rate environment, many investors hold legacy mortgages at sub-2% fixed rates that would be destroyed by a full remortgage. A second charge lender takes a legal charge behind the existing first charge mortgage, providing a separate loan against the available equity. Rates are higher than a standard first charge (typically 6–12% depending on LTV and credit profile), but the maths often favours paying the higher second charge rate on a smaller amount rather than remortgaging the entire facility at current market rates. Brokers who specialise in second charges have access to lenders that don't appear on comparison sites.
