Audit planning is the process of defining an audit’s scope, timing and direction, assessing risks and controls, and agreeing a detailed work programme before fieldwork starts. Under ISA (UK) 300, auditors must set an overall audit strategy and audit plan, so large practices allocate resources, deadlines and risk responses upfront.
Setting the parameters and direction of the audit engagement begins with deciding what the audit’s scope is. It outlines the specific topics, procedures, or actions to be examined, the time to be spent on them, and the goals to be achieved. Auditors can effectively allocate resources, prioritise their efforts, and provide stakeholders with relevant insights by providing a clear definition.
Key takeaways
- Before anyone starts fieldwork, you need to settle what the audit covers, when it happens and how you’ll tackle it. That’s what audit planning is, and ISA (UK) 300 says you have to do it.
- Most people split it into five stages: scoping, spotting risks and controls, mapping out the plan and timeline, collecting evidence in the field, and then reporting and following up.
- Back in July 2026, the FRC published its findings. It had inspected 116 audits, and 79% of them needed only limited improvements at most.
- Running a larger practice? Stick to one methodology everyone uses, get your risk assessment written down early, and don’t overpromise on resources.
- Don’t treat the plan as a one-off. Things change mid-engagement, so revisit it and update it as you go.
What Is an Audit, and Why Is Audit Planning Important?
Audit planning matters because it fixes scope, resources and timelines before fieldwork begins, which reduces rework and keeps teams focused on the highest risks. ISA (UK) 300 requires auditors to plan the audit so that it is performed in an effective manner.
An audit is an independent examination of an organisation’s financial information, systems and controls, carried out to form an opinion on the financial statements. It entails scrutinizing transactions, systems, and controls to guarantee adherence to rules and pinpoint possible hazards.
Planning sets the stage for the entire audit process and really is the keystone of a successful audit. By getting your goals, scope, resources & timelines all lined out ahead of time, auditors can work way more efficiently and avoid wasting time on stuff they don’t need to do. Doing your homework in advance lets you focus on what really matters, use your resources wisely, and adjust your approach if you hit any tricky risks along the way.
Regulators are super keen on consistency. In their 2026 Annual Review of Audit Quality, the Financial Reporting Council (FRC) found that 79% of the 116 audits they looked at needed no more than a tweak or two, similar to the 2024-25 results (CPIA summary of the FRC review; AccountingWeb – 29 July 2026).
If you don’t put in the effort to plan, audits start to get disorganised and pretty inefficient. You’ll be way more likely to miss deadlines or overlook important stuff if you start an audit without a clear idea of what you’re doing.
What Are the Key Steps in Audit Planning?
The key steps are defining the scope, identifying risks and controls, building the audit plan and timeline, gathering evidence through fieldwork, and reporting with follow-up. ISA (UK) 300, effective from 15 December 2019 and last updated on 20 May 2022, requires an overall audit strategy and a detailed audit plan (FRC, ISA (UK) 300).
| Stage | What auditors do | Planning output |
| 1. Define scope | Agree the areas, period, standards and objectives the audit will cover | Scope and engagement terms |
| 2. Identify risks and controls | Assess internal and external risk factors and evaluate how controls respond | Risk assessment |
| 3. Build plan and timeline | Assign tasks, owners and due dates by availability and experience | Audit strategy and audit plan |
| 4. Gather evidence | Observation, inquiry, reperformance and sampling | Documented audit trail |
| 5. Report and follow up | Communicate findings and track corrective actions | Audit report and action log |
Planning an audit requires having a clear understanding of its scope. Auditors must establish the parameters within which they will work before getting into the finer points of financial statements and procedures.
Moreover, the scope clearly defines the areas the audit will cover, helping both the auditee and the auditor set expectations. It ensures that all parties agree on what will be examined and evaluated.
When auditors clearly define the audit scope, they focus on the most important areas needed to achieve the audit’s objectives. This focused strategy increases the audit process’s efficacy while also saving time.
How Do Auditors Identify Risks and Controls?
Auditors identify risks by assessing the internal and external factors that could affect an organisation’s objectives, then evaluate whether management’s controls reduce those risks. A control is a procedure or policy that management puts in place to address an identified risk.
In audit planning, identifying risks and controls is an essential first step. Management implements controls to reduce risks that may undermine organisational goals.
Auditors identify risks by evaluating internal and external factors that affect the organisation’s operations. Understanding the business climate, market trends, legal requirements, and historical performance information are necessary for this.
Controls are procedures or guidelines put in place by management to deal with risks that have been identified. Auditors must assess how effectively these controls reduce risks and help achieve organisational objectives.
Auditors may concentrate their attention on areas with the greatest risk exposure by carefully identifying risks and controls during the planning stage. This focused strategy guarantees an audit procedure that is more effective and efficient overall.
How Do You Create an Audit Plan and Timeline?
Create an audit plan by setting objectives and scope, splitting the work into phases, assigning tasks by availability and experience, and fixing a due date for each task. Review the timeline regularly so unexpected issues do not derail delivery.
When you’re developing an audit plan & schedule, professionalism is key. Start off by defining the scope of work and the audit’s end goals – this helps you get a sense of what areas of the audit need more digging.
Then break the audit process down into smaller, bite-sized phases, and assign tasks to team members based on what day they’re free & how experienced they are. Giving each task a deadline helps make sure the audit stays on track.
When you’re putting together your timeline, think about stuff like when team members are available, what obstacles you might run into & any outside factors that could impact things. You’ve got to be flexible because things can go wrong at any time during the audit.
To be prepared for any changes or delays, regularly review & tweak your plan as needed. Keeping everyone on the same page and sticking to the original timetable requires good communication between team members.
How Do Auditors Gather Evidence and Conduct Fieldwork?
Audit evidence is basically the facts and figures – or the raw data and the words from the people involved – that auditors are using to back up the conclusions they come to as a result of their investigation. And that evidence – it must get documented properly so it’s clear for everyone to see where we got to in the end.
The Fieldwork and Evidence Collecting bits are just as important as they sound, which is to say pretty darn important. We start actually putting the audit plan into action – collecting data, interviewing people, testing out controls – to make sure everything is working as it should be.
And while we’re out in the field doing our thing, auditors are under a lot of pressure to keep an open mind and be thorough. We’re not just looking at the bottom line; we’re digging deep into the books – the financials, internal procedures, and all the regulatory stuff too. We’re looking for any signs that something might not be quite right.
To make sure we get to the bottom of things, auditors use a few different tricks of the trade. We might conduct some form of observation –checking in on things in person or watching how they’re done. We might ask some questions – direct inquiries with the people on the ground. We might even do some of the tasks ourselves to see how they’re done in real life. And if we need to, we’ll use sampling to make sure we get a good enough picture of what’s going on. And one really important thing – all of this has to get documented so that we can go back and see exactly how we arrived at our conclusions. And to do that, we need to be transparent and clear in our record keeping.
| Technique | What it involves |
| Observation | Watching a process or control being performed |
| Inquiry | Asking management and staff questions, then corroborating the answers |
| Reperformance | Independently repeating a procedure or control to confirm the result |
| Sampling | Testing a selection of items from a population to conclude it |
What Happens During Audit Reporting and Follow-Up?
After fieldwork, auditors analyse the evidence, draw conclusions, report findings to stakeholders and track whether recommendations are implemented. A good report is clear and concise so decision-makers can act on it.
Next up in the audit planning process, the team takes a really close look at all that data they gathered on site and in evidence collection, and then uses it to come to some pretty important conclusions plus make suggestions for how things can be improved.
Reporting is a pretty big deal when it comes to audits, because it keeps all the people who need to know up to speed on the results. People in charge should ideally be able to make some smart decisions based on clear, simple information that’s laid out in a report that makes sense.
Plus, the audit team plays a significant part in follow-up – making sure that any issues that popped up during the audit get dealt with right away. They keep an eye on whether recommendations are being put into action, and check that any fixes are actually getting done.
To properly close an audit, management must be communicated with throughout this phase. By offering input, auditors can assist firms in improving internal controls and operations.
How Should Large Practices Approach Audit Planning in 2026?
Large practices should standardise planning methodology across teams, document risk assessment early, resource specialists realistically, and link planning to their system of quality management. The FRC’s July 2026 review shows consistency is the challenge: among other public interest entity (PIE) audit firms, 46% of inspections needed no more than limited improvements, up from 38% a year earlier and 21% two years earlier (CPIA).
| Planning area | What large practices should do | Reference |
| Methodology | Use one planning template and review checklist across offices and teams | ISA (UK) 300 |
| Risk assessment | Complete and document risk assessment before designing further procedures | ISA (UK) 315 |
| Quality management | Tie engagement planning to the firm’s system of quality management | ISQM (UK) 1 |
| Capacity | Map partner, manager and specialist availability against peak deadlines | Audit plan timeline |
| Technology | Use data analytics and automation to test full populations and flag exceptions early | Audit plan |

People Also Ask
What is audit planning?
Audit planning is where auditors lay out the blueprint for their engagement – determining what needs to be done, by when, and in what order, with a clear eye on the bigger picture. ISA (UK) 300 demands an overall audit strategy and a detailed audit plan – two essential pieces of the puzzle that set the whole process in motion. When planning is done well, bigger firms can allocate their resources, set realistic deadlines and prioritise their testing efforts before sending the team out into the field.
What is the difference between an audit strategy and an audit plan?
The overall audit strategy sets the scene, deciding when and how we’re going to approach a job and what our main goals are. The audit plan gets down to the nitty-gritty, breaking down what each team member needs to do, when they need to do it and how they’re going to go about it. The strategy gives us a broad outline of what we’re doing and when; the plan fills in the details.
When should audit planning start?
Planning never really stops, it just ebbs and flows. From the moment we start an engagement, we’re planning and adjusting as we go along. We start off by getting some basics sorted like checking our independence and making sure the client’s on board. And then we’re continuously updating our strategy and plan as things change – not just at the beginning, but all the way through to the end of the audit.
What should large practices prioritise when planning audits in 2026?
If you’re a big practice, it’s a good idea to make sure you’ve got a consistent approach across all your teams, to document your risks early, to make sure you’ve got the right resources and to schedule in regular check-ins to make sure everything’s on track. And let’s be honest, with the FRC’s review showing that only 21% of audits needed a lot of improvement, consistency is key. Using standard templates and keeping an eye on your plans can help you hit that mark.
Can outsourcing support audit planning?
Absolutely. You can use an outsourced team to do all the background work like putting together working papers, updating the trial balances and running data analysis while the partner takes care of the high-level strategy and makes the judgement calls. Our Audit Services and Outsource Audit Support Service helps UK practices keep up with the demand during peak periods while keeping the quality control in-house.
Conclusion: What Should You Do Next?
Gaining proficiency in audit planning is essential to making sure that every audit procedure is successful. Auditors can improve the quality and efficiency of their audits by closely adhering to the essential steps in audit planning, which include comprehending the scope, identifying risks and controls, developing a comprehensive plan and schedule, carrying out fieldwork efficiently, and concluding with comprehensive reporting and follow-up.
