How does the mortgage application process work in the UK?

The mortgage application process differs depending on the type of mortgage that you apply for.

For example, remortgages and interest-only mortgages require specific criteria to be met before they’re approved.

Regardless of which type you’re interested in when applying for a mortgage, you’ll follow similar steps:

  • Speak to a mortgage broker: Consider talking to a mortgage broker about the kind of mortgage options available to you that align with your personal circumstances. You could also talk to your bank about your options.

  • Gather your essential documents: Make sure you have all the information you need to successfully apply for the mortgage you want.

  • Put forward your application: Once you have passed all security and credit checks, you may proceed with submitting your mortgage application. 

In most cases, a mortgage broker can also make it easier to apply for a mortgage.

A mortgage broker can assist you in collecting the relevant documents, assessing your affordability, and recommending mortgages based on your financial circumstances.

What documents do you need to apply for a mortgage?

Knowing what you need to apply for a mortgage is crucial for a successful application.

To apply for a mortgage in the UK, lenders will typically require the following documents:

  • Utility bills

  • Payslips from the last three months

  • A passport or driving license to prove your identity

  • Bank statements of your current account for the last three to six months

  • A statement of two to three years’ accounts if you’re self-employed - an accountant can help you with this

  • A P60 form from your employer

All of this information must be up-to-date and legitimate, and you may need to provide certified copies of original documents instead of scans or copies. 

Speed and legitimacy when signing a mortgage deed are all fundamental to a successful mortgage application.

You may also need to detail outgoing costs that may affect your ability to secure a mortgage, such as insurance, and other expenses, including general living costs, childcare, and entertainment.

  • Manage your debt-to-income ratio: Supplementing your debt obligations with multiple income streams or reducing your debt-to-income ratio before applying for a mortgage will make your application more appealing to lenders.

  • Use a mortgage calculator: Knowing how much you can likely borrow shows banks you are prepared for a mortgage and understand your financial obligations.
