    Second charge rates typically range from 8-15%. If left blank, we'll use 9.9%.

    Remortgage Details

    Expected terms if you remortgage with additional borrowing

    Note: Remortgaging will trigger your ERC if you're within your fixed period. If your current lender offers a Further Advance without ERC, that would typically be the cheapest option - check with your lender first.

    Typical range: £0 - £1,999

    When is a Second Charge Better?

    • You have a low rate you want to keep
    • High ERC on your current mortgage
    • LTV above 85%
    • Need flexible criteria (debt consolidation)
    • Faster completion needed

    What About Further Advance?

    A Further Advance from your current lender is often the best option if available - typically no ERC and lower rates than second charge.

    Contact your lender to check if FA is available. This calculator helps when FA isn't an option.
