The Financial Assessment is one of the most detailed and rigorous stages of the Post Office appointment process. Whilst many applicants assume it simply confirms they have sufficient funds to purchase the business, the assessment is considerably more comprehensive.
Throughout the process, the Post Office builds a detailed picture of both the applicant and the proposed business. Your funding arrangements, Business Plan, financial forecasts, personal finances and commercial assumptions are all reviewed together to assess whether the business is financially sustainable and whether your application presents a realistic and credible proposition.
Applicants should also be prepared for extensive financial due diligence. Supporting documentation is carefully scrutinised, source of funds may need to be evidenced, and additional information or clarification is frequently requested. The Financial Assessment isn’t simply about entering figures into an online form—it’s about demonstrating that every figure can be supported and every assumption justified.
Perhaps most importantly, the Financial Assessment should not be viewed in isolation. It forms part of your overall Post Office application, alongside your Business Plan and the two-hour Post Office interview. The strongest applications present one consistent story, where your financial forecasts, funding arrangements, operational plans and interview responses all reinforce one another.
This guide explains each section of the Financial Assessment, highlights what the Post Office is looking for, identifies common mistakes and provides practical guidance to help you prepare a stronger, more consistent submission.
Understand the Financial Assessment Process
The Financial Assessment forms one of the most important stages of the Post Office appointment process. Before beginning, it’s important to understand that the assessment is not simply about demonstrating that you have sufficient funds to purchase the business. The Post Office uses this stage to assess the overall financial viability of both the applicant and the proposed business. Every section contributes towards building one complete financial picture, helping the assessor understand how the business will be funded, operated and managed successfully.
About You
The first section focuses on your personal background and previous experience.
Typical information includes:
What the assessor is looking for
This section helps build confidence that you have the experience and background to operate a successful Post Office business.
Legal Business Structure & Company Details
This section explains how the business will be owned and operated.
Typical examples include:
The legal structure should support both the funding arrangements and your wider business plan.
Property Inforrmation
You’ll be asked to provide details relating to the premises, including ownership or lease arrangements.
This information feeds into the wider financial assessment and helps establish the operating costs associated with the business.
Start Up Costs & Funding
This is one of the most important sections of the assessment.
You’ll normally explain:
The figures entered here should align with the Business Plan and your wider financial forecasts
Staffing Costs
This is one of the most important sections of the assessment.
You’ll normally explain:
The figures entered here should align with the Business Plan and your wider financial forecasts.
Business Plan
The Business Plan is the financial engine behind the entire assessment.
Your three-year forecast should bring together:
Every figure should be commercially realistic and supported by the assumptions you provide later in the assessment.
Personal Income, Liabilities & Expenditure
This section focuses on your own financial position.
It considers:
The Post Office wants to understand whether your personal financial circumstances remain sustainable after purchasing the business.
Business Assumptions
This is where you explain the thinking behind your financial forecasts.
Applicants are typically asked to explain assumptions relating to:
Good assumptions are realistic, evidence-based and consistent with the figures already provided throughout the Financial Assessment.
Understanding Financial Due Diligence
The Financial Assessment isn’t simply about demonstrating that you can afford to purchase the business. The Post Office also carries out extensive financial due diligence to understand where funds have come from and to satisfy its legal and regulatory responsibilities.
Applicants should expect supporting documentation to be reviewed carefully, with additional questions often asked where clarification is required.
This level of scrutiny is entirely normal and forms an important part of the appointment process.
Every Figure Should Be Supported
One of the most common misconceptions is that completing the Financial Assessment simply involves entering figures into an online form.
In reality, many of those figures need to be supported by documentation.
The assessor isn’t only reviewing the numbers—they’re assessing whether those numbers can be evidenced and whether the overall financial position is clear, consistent and credible.
Providing complete information at the outset can significantly reduce delays later in the assessment.
The Art of Completing Your Financial Assessment
Completing the Financial Assessment isn’t simply about filling in the boxes. Every section should support the next, creating one consistent financial story that demonstrates your ability to purchase, operate and grow the business successfully.
Your funding arrangements should support your Business Plan. Your staffing costs should reflect your projected sales.
Your personal drawings should remain affordable alongside your household commitments.
Your business assumptions should explain how your forecasts will realistically be achieved.
Alongside the Financial Assessment, applicants are also required to complete a detailed Post Office interview, often lasting around two hours. During the interview, you’ll be assessed across a wide range of operational and commercial topics, including customer service, retail management, staffing, compliance, community engagement, business planning and financial awareness.
The Financial Assessment and Interview should reinforce one another. The financial decisions described in your Business Plan should be consistent with the commercial understanding you demonstrate during the interview.

When does the Financial Assessment take place?
It forms part of the wider appointment process after your application has progressed to the Financial Assessment stage. The exact timing varies depending on your application and the branch.

No. It assesses the overall financial viability of the proposed business, your funding arrangements and whether the application presents a realistic commercial case.
