Borrow £5,000 or more with an additional loan
The borrowing is secured against your home in the same way as your mortgage.
With no product fees or early repayment charges on some additional loans, it's an easy way to find the money for the things you need and you will need to pay it back on a repayment basis. It doesn't need to be the same term as your mortgage. You could choose a term between 5 and 35 years.
To apply for an additional loan, your existing mortgage and the amount you want to borrow needs to be less than 85% of your home's value.

Borrow against your mortgage
With a Flexible Offset mortgage, you already have an agreed limit for borrowing additional money at the same rate as your mortgage. You can use any available funds you have on your mortgage and can repay this either on a repayment or an interest only basis. In the future, this may be restricted to a repayment basis only.
You can use Online Banking to access your available funds. Please note, if you want to withdraw any available funds in the future, we may check that you will be able to afford it.
If the limit that was agreed when you took out your mortgage isn’t enough, you can ask for a Credit Limit Review (charges will apply).The maximum LTV you may be able to borrow on your mortgage is shown in your original Key Facts Illustration.

Interest rates change from time to time and we reserve the right to change our SVR in the future (because of either funding costs or mortgage market conditions).

You have an interest only mortgage if:
your mortgage is described as interest only on your paperwork and mortgage statement
your monthly payments do not pay off the capital (the money you've borrowed) on your mortgage.
you have an endowment, ISA or other repayment plan to pay off your mortgage.
This is where you only have a single loan active on your mortgage account. You could have more than one active loan on your mortgage if:
you've taken out an additional loan with us;
you've transferred a product and increased your overall mortgage when you moved house; or
you have more than one type of repayment method i.e. part of your loan is on repayment and part is on interest only.
If you're unsure, your latest annual mortgage statement will show the number of active loans. Please ignore any loans with a £0.00 balance.
