What's a Decision in Principle?

Before applying for a mortgage, and often before making an offer on a property, you’ll need a Decision in Principle (DIP). This is also known as an Agreement in Principle (AIP) or a Lending Certificate. It confirms that we'd be prepared to lend to you. 

Getting a DIP involves a soft credit check and won’t affect your credit score.

The Decision in Principle takes into account:

  • Whether you can afford the amount you're looking to borrow, based on your income and outgoings as well as other factors
  • Our lending criteria so we remain responsible lenders

Applying for a Decision in Principle

You can apply for a DIP online, by phone or in branch. It’s free of charge and there’s no obligation to apply for one of our mortgages afterwards. 

If at any time you would like to speak to somebody about your DIP, pop into your local branch or call us on 0800 30 20 11.

Key stages and timescales

What you'll need to apply for a DIP

  • Three years of address history
  • Proof of your income and outgoings

Upon completing your DIP application, we should be able to tell you immediately whether we can, in principle, lend you the amount you need. If you’re applying online, we may need to call you for some extra information.

How long will the Decision in Principle be valid for?

It's valid for 90 days.

Mortgages are secured on your home. You could lose your home if you do not keep up payments on your mortgage.
