What is a Decision in Principle?

Before a full application, you'll need to get a Decision in Principle - where we'll tell you if we can offer you a mortgage and exactly how much you’re able to borrow.

It takes as little as 10 minutes

With some details from you we’ll tell you whether we can lend to you and how much.

It won't affect your credit rating

Our checks will not appear on your credit file at this stage of the application.

It lasts for 30 days

If you need more time, you can easily retrieve your details and resubmit your Decision in Principle for reapproval.

How much could I borrow?

It helps at this stage to have an idea of how much you would be able to borrow for your mortgage.

Can I afford it?

We also have a repayment calculator which will give an estimated monthly repayment figure for the amount you want to borrow.

I'm ready to get started!

Ok, you just need to read the following first:
