What HSBC UK says about the yearly allowance
HSBC UK says that on a fixed-rate mortgage you have an annual overpayment allowance, equivalent to 10% of the outstanding balance of your mortgage, and that anything over 10% will incur an early repayment charge.
If you have a fixed-rate mortgage, you’ll have an annual overpayment allowance (AOA), which is the amount you can overpay each year without incurring any charges.
Your AOA is equivalent to 10% of the outstanding balance of your mortgage.
Anything over 10% will incur an early repayment charge (ERC).
When the allowance resets
HSBC UK says the allowance resets annually, either on the date your mortgage account was opened or, if you have switched rates before, on the start date of your fixed-rate period.
It will reset annually, either on the date your mortgage account was opened, or on the start date of your fixed-rate period if you’ve previously switched mortgage rates.
What HSBC UK says about early repayment charges
HSBC UK says its early repayment charge is calculated as 1% of the amount repaid early above the annual allowance for each remaining year of the period during which the charge applies, reducing daily, and that it is capped at 5% on a 10-year fixed rate product.
The ERC is calculated as 1% of the amount repaid early, above any annual overpayment allowance, for each remaining year of the period during which the ERC applies, reducing on a daily basis.
However, if you’re on a 10-year fixed rate product, the ERC is capped at 5%.
Tracker and variable rate mortgages
HSBC UK says that with a tracker or variable rate mortgage there are no limits or charges for making overpayments.
