Mortgage application

What do I need to apply for a mortgage?

Getting prepared for when you apply for a mortgage

Before you apply for a mortgage, it will be useful to have several documents to hand as well as having a good understanding of your finances to help prepare you for getting a mortgage.

Read on to find out what documents you may need to apply for a mortgage.

1. Check your credit report

You can view your credit score on our app or if you don’t have the NatWest app you can use various platforms such as Experian, Equifax or ClearScore.

There are ways to help improve your credit score (such as registering on the Electoral Roll at your main address) which you may want to try and tackle if you already know what your credit score is.

2. Proof of ID

A passport or driving license are the more commonly used documents for proof of ID but we will accept other forms of ID if you don't have these. You'll also need to make sure these documents are in date.

3. Proof of address documents

These can include council tax bills, utility bills, bank statements and should be dated within the last three months.

4. Evidence of where your deposit is coming from

This is important as lenders will need to see Proof of Deposit to understand where your deposit is coming from.

  • If your deposit is from your savings, you’ll need to provide evidence via bank statements and any large payments will need to be explained. The bank statements will also need to show your name and address.
  • Gifted mortgage deposits will usually require a signed letter from the person who is gifting you the money. At NatWest, we require a signed letter or email (no signature required) from the gifting party, confirming the gift is either non repayable or repayable. 

5. Proof of income


Last 3 months payslips. If you have recently started a new job or changed salary, you’ll need to be able to provide proof of your salary.

If you would like us to consider any additional bonus payments or overtime we would need to see the corresponding payslips or the Year to Date figure on the payslip.

Bank statements

Last 3 months bank statements. This should be the account that your salary is paid into. This is to ensure figures match on payslips compared to the relevant bank account.

We may request to see bank statements from other bank accounts you hold to help us with eligibility criteria. To find out more about eligibility criteria, read our guide to mortgage eligibility.

We can also consider letters from managers or the business you work for if you are unable to provide payslips or bank statements.

6. Proof of expenses

As well as proof of income, expenses are also needed to ensure that the mortgage loan amount suits your lifestyle and requirements.

Lenders will look for any financial commitments that may have an effect on how much you can afford in relation to your monthly mortgage repayments.

What if I'm self-employed or a freelancer?

If you’re self-employed, you’ll need to provide the following additional documents required for proof of income:

Proof of income (2 years)

  • Certified accounts
  • SA302 form and tax year overview from HMRC
  • Business bank statements
