The Bradford Factor is a formula used by many UK businesses to get a clearer picture of employee sickness, but it’s not just about counting days off. Its real power lies in highlighting the difference between a single, longer-term illness and a pattern of frequent, short-term absences.
What it boils down to is this: multiple, unpredictable single days off can cause far more operational chaos than one continuous, planned-for period of sickness, even if the total number of days absent is identical.
What Is the Bradford Factor and Why Does It Matter?
Every manager knows that dealing with employee absence is a constant balancing act. While a long-term illness certainly presents challenges, you can usually plan around it. The real day-to-day headache often comes from persistent, short, and unplanned sick days. This is exactly what the Bradford Factor was designed to spotlight.
It’s not just about how many days an employee is away; it’s about the pattern of that absence.
Imagine this scenario: one of your team members is off for two solid weeks to recover from minor surgery. It’s one event, and you can arrange cover. Now, contrast that with ten different employees calling in sick for one day each over that same two-week period. That’s unpredictable, disruptive, and puts a huge strain on everyone else trying to pick up the slack.
Highlighting Disruptive Patterns
The thinking behind the Bradford Factor is that frequent, short absences have a much bigger negative impact on productivity and team morale. The formula itself is straightforward but very effective at revealing these patterns.
S² x D = Bradford Factor Score
Here, S represents the number of separate ‘spells’ or instances of sickness, and D is the total duration in days. This is typically calculated over a rolling 52-week period.
The crucial part is squaring the number of spells (S²). This simple mathematical step means the formula heavily penalises repeated absences. It’s designed to flag the difference between someone who is genuinely unwell for a longer period and someone whose attendance is becoming erratic.

Why Tracking This Matters for Your Business
By keeping an eye on Bradford Factor scores, you can spot potentially problematic attendance patterns before they spiral. It gives managers a consistent, data-driven starting point to open up a supportive conversation with an employee.
Is there an underlying health issue? Are they struggling with stress? This isn’t about punishing people for being ill; it’s about identifying who might need support and maintaining stability across the business.

Calculating the Bradford Factor Score Step by Step
Getting to grips with the maths behind the Bradford Factor is the first step to using it with confidence. The formula itself is pretty simple, but its real power is in how it weights the frequency of absence, turning abstract patterns into a hard number you can use to manage your team.
The calculation breaks down like this:
S² x D = Bradford Factor Score
In this formula, S is the total number of separate spells (or instances) of sickness, and D is the total number of days an employee has been off. This is almost always calculated over a rolling 52-week period.
The crucial part is squaring the number of spells (S²). This is what gives the formula its punch. It means that lots of short, sharp absences will rack up a much higher score than one single block of long-term illness, even if the total days off are identical.
Putting the Formula into Practice
To see just how dramatic this can be, let’s look at two employees. Both have been off for a total of ten days over the last year, but their situations are very different.
- Employee A (Amelia): Amelia has a single, two-week absence (10 working days) to recover from a minor operation.
- Spells (S) = 1
- Total Days (D) = 10
- Her score is: 1² x 10 = 10 points
- Employee B (Ben): Ben takes ten separate, single-day absences throughout the year for various minor ailments.
- Spells (S) = 10
- Total Days (D) = 10
- His score is: 10² x 10 = 1,000 points
Even with the same number of days off, Ben’s score is a whopping 100 times higher than Amelia’s. This is the Bradford Factor in action—it’s designed to flag the disruptive, unpredictable nature of repeated absences, not to penalise someone for a genuine, long-term health issue.
As you can see, the score climbs exponentially with every separate instance of absence. It’s the frequency, not the duration, that really sends the score soaring.
Where Did It Come From and How Is It Used?
The Bradford Factor became a popular tool for UK employers back in the 1980s. It gave them a straightforward, numerical way to identify and manage the kind of short-term sickness that causes the most operational headaches.
Its name comes from research conducted at the Bradford Management School, and its purpose has stayed the same: to pinpoint absence patterns that put the most strain on a business. While the formula is a constant, how it’s applied can vary hugely. Some companies might set a trigger for an informal chat at a score as low as 50, while others won’t begin any formal process until a score hits several hundred. You can discover more about the Bradford Factor’s history and how it’s used.
Nailing this calculation is the foundation for building a fair and effective absence policy. Remember, it’s not about automatically starting disciplinary action. It’s about using the score as a trigger to open up a supportive conversation and find out what’s really going on behind the numbers.
Building a Fair and Legally Compliant UK Policy
Getting the Bradford Factor right is about more than just crunching numbers. It’s about building a policy that’s robust, fair, and stands up to scrutiny under UK employment law. A score is just a number, after all. Your policy is what gives that number context and turns it from a blunt instrument into a genuinely useful management tool.
Think of your policy as the company’s commitment to handling absence consistently. It tells your team that you have a structured, transparent approach, while also protecting the business from very real legal risks. It’s the essential bridge between the data and the real-world conversations and actions that follow.
Grounding Your Policy in UK Law
When you start looking at sickness patterns, you’re stepping into sensitive territory that’s tightly regulated by UK law. There are two big pieces of legislation you absolutely have to get right.
First up is the Equality Act 2010. This is non-negotiable. The Act puts a clear duty on employers to make “reasonable adjustments” for employees with disabilities.
Under the Act, a disability is defined as a physical or mental impairment that has a ‘substantial’ and ‘long-term’ negative effect on a person’s ability to carry out normal day-to-day activities.
What does this mean for your Bradford Factor policy? Simple: you can’t treat every absence the same. If an employee’s absence is directly linked to a known disability, you usually need to discount it or at least record it separately. Letting these absences push someone’s score over a disciplinary trigger point could easily be classed as disability discrimination.
Data Protection and GDPR Compliance
The second legal minefield is the General Data Protection Regulation (GDPR). Information about an employee’s health is considered ‘special category data’, which is a formal way of saying it needs the highest possible level of protection.
Your absence policy must be crystal clear about how you will collect, store, and use this data. You need to cover:
- Purpose: Be upfront. Explain that you’re tracking absence to manage operational cover and support employee wellbeing.
- Security: Detail the security measures you have in place. This data should be locked down, typically within a secure HR system.
- Access: Define exactly who can see this information—usually just the employee’s line manager and key HR staff.
Get this wrong, and you’re not just looking at hefty fines but serious damage to your reputation. The key here is transparency. Your team needs to understand why this data is being tracked and how it will be used. A good template employee handbook can provide a solid foundation for drafting these kinds of policies.
Creating a Transparent Framework
A legally sound policy is useless if no one understands it. It needs to be written in plain English, free from corporate jargon, and easy for everyone to find. The aim is to take the mystery out of absence management and build a bit of trust.
Your policy must spell out the exact trigger points for action. This kills ambiguity and stops managers from applying the rules differently from one team to the next. Clearly state what score leads to an informal chat, what triggers a formal review, and the thresholds for any potential disciplinary warnings.
When you have that level of clarity, a conversation prompted by a high Bradford Factor score is never a surprise. It becomes an expected part of a process the employee already understands. This simple step can transform a potentially tense meeting into a structured, supportive discussion focused on figuring out what’s really going on.
Setting Triggers and Taking Appropriate Action
A Bradford Factor score on its own is just a number. It’s what you do with it that counts. This is where we shift from the theory to the practical, turning a data point into a genuine tool for managing absence fairly and, most importantly, humanely.
The whole point is to remember that a high score isn’t an automatic red card. Think of it as a smoke alarm – it’s a clear, consistent signal for a manager to go and check what’s going on. It’s a prompt to ask “why?” and start a supportive conversation, transforming a cold calculation into a far more understanding way to handle bradford factor sickness.
Building a Tiered Framework
The most effective and fairest way to use the Bradford Factor is by creating a clear, tiered system of trigger points. This builds consistency right across the business, so everyone knows where they stand and every employee is treated the same. It takes the guesswork out of the equation for managers and staff alike.
A typical framework will have different score thresholds that kick off escalating levels of management action. This isn’t a one-size-fits-all model; you absolutely should tweak the scores to fit your company culture and the realities of your operations. The principle, however, stays the same: the higher the score, the more structured the conversation needs to be.
A tiered approach ensures that your response is always proportionate. A low-level score might just need an informal chat, while a significantly higher one naturally calls for a more formal meeting.
This entire process is about opening a dialogue, not jumping straight into a disciplinary procedure. That first chat should always be about understanding and support, trying to get to the root cause of the absences.
Example Trigger Points and Actions
To give you a better idea of what this looks like in practice, here is a sample framework. Remember, the scores are just examples – what really matters is the supportive structure and the intention behind each stage.
Here’s a sample framework illustrating how different score ranges can trigger escalating levels of management review and support.
Example Bradford Factor Trigger Points and Actions
| Bradford Factor Score Range | Suggested Management Action | Focus of the Conversation |
|---|---|---|
| 51 – 200 points | Informal chat during a return-to-work interview. | A supportive check-in to see if the employee is okay and to make them aware their score is being monitored. |
| 201 – 400 points | Formal review meeting with the line manager (and possibly HR). | A structured discussion about the absence pattern, exploring potential underlying causes and discussing what support the company can offer. |
| 401 – 600 points | First formal written warning. | Clearly outlining the impact of the absences on the business and setting clear expectations for improvement. |
| 601+ points | Final written warning or consideration of further disciplinary action. | A serious conversation about the potential consequences if attendance does not improve, up to and including dismissal. |
It’s vital that managers use their discretion at every stage. Is the employee a new parent whose child is often unwell? Do they have an underlying health condition you weren’t aware of? The score is a guide, not a judge. For a much deeper look into this process, our blog has a comprehensive guide to setting effective Bradford Factor trigger points.
Ultimately, the goal is to use these triggers to spark communication and offer support where it’s needed most. That’s how you turn a simple score into a powerful tool for positive change.
How HR Systems Take the Pain Out of Bradford Factor Tracking
Let’s be honest, trying to manually calculate Bradford Factor scores is a nightmare. Keeping track of every absence for every employee over a rolling 52-week period is a huge administrative headache. It’s not just tedious; it’s a process riddled with potential for human error, which makes applying your absence policy consistently a real challenge.
This is exactly where a good HR system comes in. It can completely change the game, turning a soul-destroying task into a genuinely useful management tool.
The days of battling with complex spreadsheets are thankfully over. An integrated HR platform automates the tracking of bradford factor sickness from start to finish, killing the risk of miscalculations and freeing up your HR team and line managers to focus on more important things.
Real-Time Scores and Automated Alerts
A modern HR system crunches the numbers for you. As soon as a new absence is logged, the employee’s Bradford Factor score is recalculated instantly. No more delays, no more out-of-date information. Managers always have the latest score at their fingertips.
But it’s the automation that truly makes a difference. You can set up your company’s specific trigger points directly in the system. When an employee’s score hits one of those thresholds, an automatic alert can be sent straight to their line manager and the HR department.
This simple feature ensures that important conversations happen right away, not weeks down the line when the moment has passed. It shifts your whole approach from being reactive to proactive, giving managers the chance to step in and offer support before a small issue becomes a bigger problem.
The Advantage of an Integrated System
The real power move is when this automation is plugged into your wider HR ecosystem. For instance, solutions like Human Resource HR Management for Microsoft Dynamics 365 by Hubdrive are built on the Microsoft Power Platform, creating a single, reliable source for all your employee information.
Having everything connected in one place gives you some major advantages:
- Live Dashboards: With tools like Power BI, managers and HR leaders get a bird’s-eye view of absence data in real-time. You can spot trends across different teams or the entire company with just a few clicks.
- Consistent Policy Application: Automation is the key to fairness. By taking the manual guesswork out of the equation, the system ensures your absence policy is applied the same way for everyone, which significantly reduces the risk of grievances.
- Secure Data Handling: All sensitive absence information is kept safely within your own Microsoft 365 environment, making it much easier to stay on the right side of GDPR.
An integrated system does more than just track numbers; it gives you the tools to understand why people are absent and helps you build better wellbeing strategies. If you want to dive deeper into how these platforms operate, check out our guide on what an HRMS system is and its core functions.
By removing the administrative burden, automation empowers managers to focus on what truly matters: supporting their people. It ensures the Bradford Factor is used as intended—a fair, consistent, and data-driven starting point for a conversation.
Making the switch from manual tracking to an automated, integrated system is a fundamental step forward. It guarantees accuracy, promotes fairness, and delivers the strategic insight you need to manage absence effectively while supporting your team.
Beyond the Score: A Smarter Way to Manage Absence
A Bradford Factor score can be a useful red flag, but it should never be the only tool in your box. Think of it as a smoke alarm – it tells you there’s a problem, but it can’t tell you what’s burning or why. If you rely only on the numbers, you risk creating a culture of presenteeism. That’s when sick employees drag themselves into work, worried about hitting a trigger score, which isn’t good for them or anyone around them.
Genuine absence management is about more than just data. It’s about taking a more human approach, getting to the root causes of sickness, and building a workplace based on trust and wellbeing, not fear.
Thinking Holistically About Attendance
A truly effective attendance strategy blends the hard data from the Bradford Factor with softer, people-focused actions. It’s about looking past the score and starting a conversation.
Here are a few complementary strategies that make a real difference:
- Meaningful Return-to-Work Interviews: This is your best opportunity to connect. Frame these chats as a supportive check-in, not an interrogation. The goal is to understand what happened and see if there’s anything you can do to help.
- Flexible Working: Offering flexibility in hours or location can be a game-changer for people juggling health conditions, family needs, or other personal challenges that often lead to those disruptive short-term absences.
- Proactive Wellness Initiatives: Instead of just reacting to absence, get ahead of it. Investing in things like workplace wellness programs shows you’re committed to employee health, which can prevent issues from escalating.
The goal is to shift from a mindset of punishment to one of prevention. When you invest in your team’s health and create a supportive environment, you start fixing the very problems that cause high Bradford Factor scores in the first place.
This approach sends a clear message: you see your employees as people, not just numbers on a spreadsheet.
Learning from a Real-World Example
The pitfalls of a purely data-driven approach are well known. Take the HM Prison Service in the UK. They introduced a Bradford-style scoring system back in 2001. By 2006, they’d seen a significant drop in sick days – a roughly 25% reduction across their 48,000 staff.
But here’s the catch: that drop can’t be pinned on the formula alone. Alongside the scoring system, they also beefed up their occupational health services and support systems while simultaneously bringing in tougher disciplinary measures. It begs the question: did absence fall because people felt better supported, or because they were afraid of being sacked? You can read a more detailed breakdown of these findings and their implications.
This case study is the perfect illustration. The Bradford Factor can absolutely be part of an effective strategy, but it only works when it’s balanced with genuine human support and a willingness to understand individual circumstances. It’s a tool to start a conversation, not to end one.

Frequently Asked Questions
When it comes to using the Bradford Factor, it’s easy to get tangled up in the details. Let’s clear up some of the most common questions we hear from UK employers so you can use this tool fairly and effectively.
Can You Dismiss Someone Based on Their Score Alone?
Absolutely not. Think of a high Bradford Factor score as a red flag, not a final verdict. In the eyes of UK employment law, the score is simply a trigger to start a conversation, not a reason in itself for dismissal.
You must follow a fair and formal process. That means sitting down with the employee, listening to the reasons behind their absences, and looking at their unique situation. Only after that can you consider any disciplinary action. The score gets the ball rolling; it doesn’t decide the outcome of the game.
Do Disability-Related Absences Count Towards the Score?
This is where you need to be extremely careful. The Equality Act 2010 is very clear: employers must make “reasonable adjustments” for employees with disabilities. Counting absences directly linked to a disability in your Bradford Factor calculation is a huge risk and could easily lead to a discrimination claim.
The best practice is to record these absences separately and exclude them from the score entirely. Your absence policy needs to spell this out explicitly to ensure you’re treating people fairly and staying on the right side of the law.
What Is a Bad Bradford Factor Score?
There’s no magic number here. A “bad” score is whatever your company policy says it is. It’s all about the trigger points you decide to set.
One business might decide a score of 200 warrants an informal chat, while another might not start a formal process until a score hits 500. A score only becomes ‘bad’ when it crosses a threshold that you’ve already defined and, crucially, communicated clearly to your entire team.
