What is a Mortgage Agreement in Principle?

A mortgage Agreement in Principle (AIP) is the first step to getting a mortgage, sometimes called a Mortgage Promise or a Decision in Principle.

Why apply for an Agreement in Principle?

A mortgage Agreement in Principle can speed up the home buying process.

It helps the:

  • Seller/estate agent. It gives the seller and estate agent the confidence that you’re serious about buying and can afford the property.
  • You, the buyer. The agreement will show what the lender is willing to lend you. This will help guide your property search.

How do I get a mortgage Agreement in Principle?

It’s usually a simple process that you can do with a mortgage provider either online, over the phone or face to face. You should receive a decision within around 15 minutes, depending on your circumstances.

1. Start an application

You can apply online with us or get in touch with a lender.

2. Detail your personal information

Income, monthly outgoings and how much you want to borrow. And any addresses you’ve lived at in the last three years.

3. Gather supporting documents

Payslips, bank statements, and rental or mortgage agreements.

4. Your lender does a credit check

We do a soft credit check but other lenders may do hard checks. Soft checks don't affect your credit rating, but hard checks do.

This will assess your financial situation to work out how much you could borrow.

Good to know


You’ll need to apply for a new AIP if your circumstances change. For example, if your income or outgoings change significantly. Or you decide you want to borrow more. 

Ready to apply?

It’s quick and easy to apply for an AIP online. It should take about 15 minutes.

You'll get an instant decision if you apply between 6am and 10pm Monday to Saturday, or 6am and 9pm Sunday. Otherwise, we'll give you a decision the next day.

Let’s look at the details

Important

The amount shown on the AIP is not guaranteed.​

When you make a full mortgage application, the lender may change their decision or offer different terms. This can be due to changes in your circumstances or the lender’s criteria.

Even if you have an AIP, you will still need to apply for a mortgage when you are ready.
