Buddy Punching: How to Stop Time and Attendance Fraud

Time theft might sound like a victimless crime, but it costs UK businesses an estimated £2.2 billion per year. From buddy punching to inflated timesheets, dishonest time reporting quietly drains payroll budgets, distorts labour costs and creates resentment among honest workers who shoulder more than their fair share.

The good news is that modern time and attendance technology has made most forms of time theft preventable. This guide explains the problem, its true cost, and the practical solutions available to every UK employer.

What Is Buddy Punching?

Buddy punching is the practice of one employee clocking in or out on behalf of another. The most common scenario: an employee who is running late asks a colleague to clock them in at the start of the shift so they appear to have arrived on time.

It sounds minor. It is not.

A worker who buddy-punches just 10 minutes per day costs their employer approximately 43 hours per year in paid time for work not performed. At the national living wage (as of April 2024), that is over £470 per worker per year. Scale this across a workforce of 50, 100 or 500 employees and the cost becomes staggering.

Why It Happens

Buddy punching thrives in environments where:

• Traditional punch cards or PIN-based systems are used — anyone can punch anyone’s card or enter anyone’s PIN
• There is no verification that the person clocking in is who they claim to be
• Supervision is light — managers are not present at clock-in and clock-out times
• The culture tolerates it — “everyone does it” normalises the behaviour
• Consequences are absent — if buddy punching is never detected or addressed, there is no deterrent

Other Forms of Timesheet Fraud

Buddy punching is the most visible form of time theft, but it is far from the only one.

Early Clock-In / Late Clock-Out

Workers who clock in several minutes before their shift starts or clock out several minutes after it ends, accumulating small amounts of unearned pay each day. Over weeks and months, this adds up.

Extended Breaks

Taking 45-minute breaks when 20 minutes is allocated, but recording only 20 minutes. Particularly common where break times are self-reported rather than tracked.

Inflated Timesheets

In environments where hours are reported manually (paper timesheets, spreadsheets), some workers round up their hours. An 8-hour day becomes 8.5 hours. A 37.5-hour week becomes 40. Individually small, collectively enormous.

Ghost Employees

A more serious form of fraud where a manager creates fictitious employees on the payroll and collects their wages. This is rarer but devastating when it occurs, and is usually only detected through rigorous audit processes.

Unauthorised Overtime

Workers who clock extra hours without authorisation, knowing the payroll system will process the payment automatically. This is a grey area — the hours may be genuinely worked but not approved.

The True Cost to UK Businesses

Direct Payroll Costs

The most obvious cost is paying for time not worked. If 5% of your workforce inflates their hours by 15 minutes per day, the annual cost for a 100-person operation paying an average of £12 per hour is approximately £23,400. For larger organisations, this runs into hundreds of thousands.

Payroll Processing Errors

Manual timesheets require manual processing, which introduces errors. Overpayments, underpayments, incorrect holiday accruals and miscalculated overtime all result from inaccurate time data.

Labour Cost Distortion

If your time data is unreliable, your labour cost calculations are unreliable too. This undermines budgeting, pricing decisions, project costing and resource planning.

Employee Morale

Honest workers resent colleagues who cheat the system. When buddy punching is tolerated, it sends a message that integrity does not matter. This erodes trust, engagement and team cohesion.

Compliance Risk

Inaccurate time records make it impossible to demonstrate compliance with the Working Time Regulations. If you cannot prove that workers are within the 48-hour average or receiving their rest breaks, you are exposed to enforcement action. See our guide to Working Time Regulations for more detail.

Solutions: Technology That Prevents Time Theft

GPS Clock-In Verification

GPS-enabled time clocking ensures that workers can only clock in when they are physically at the correct work location. The system records the GPS coordinates at the point of clock-in and clock-out, creating verifiable proof of the worker’s location.

How it works: The worker clocks in using a mobile app. The app captures their GPS coordinates and compares them to the expected work location. If the worker is not within the defined radius (typically 50–200 metres), the clock-in is either rejected or flagged for review.

Benefits:

• Eliminates remote buddy punching entirely
• Provides evidence of worker location for lone worker safety
• Useful for mobile workers visiting multiple sites
• Creates auditable location records

Photo Verification

Photo clock-in requires the worker to take a selfie at the point of clocking in and out. This creates a visual record that the correct person clocked in at the correct time.

How it works: The time clock app activates the front-facing camera and captures an image alongside the clock-in/out record. Managers can review photos to verify identity.

Benefits:

• Eliminates buddy punching (another person’s photo would be immediately obvious)
• Simple and non-invasive (no fingerprinting or biometrics required)
• Creates a visual audit trail
• Workers quickly accept it as normal practice

Geofencing

Geofencing defines a virtual boundary around a work location. Workers can only clock in when their device is within this boundary, and can optionally be reminded to clock out when they leave.

Benefits:

• Prevents early clock-in from home or car park
• Automatic clock-out reminders reduce forgotten clock-outs
• Different geofences for different sites in multi-location businesses

Exception Detection

Modern time and attendance systems can automatically flag unusual patterns for review:

• Clock-ins at unusual times (significantly before or after the scheduled shift)
• Missing clock-outs (which may indicate someone forgot or left early)
• Consecutive late arrivals
• Patterns of overtime without prior approval
• Breaks that exceed the scheduled duration
• Clock-ins from unexpected locations

Exception-based management means managers only need to review the unusual entries, not every single clock-in and clock-out. This dramatically reduces the administrative burden while increasing oversight.

Approval Workflows

Rather than automatically processing all clocked hours into payroll, modern systems allow for manager approval of timesheets before they are submitted for payment. Managers review the week’s time data, approve correct entries, query anomalies and adjust errors before payroll processes the data.

This creates a checkpoint that catches errors and fraud before they affect pay.

Implementing a Modern Time and Attendance System

Step 1: Audit Your Current Process

Before implementing a new system, understand your current situation:

• How do workers currently record their time? (Paper, spreadsheet, basic clock, honour system?)
• What verification exists? (None? Supervisor oversight? PIN codes?)
• What are the known problems? (Late arrivals, missing records, disputed hours?)
• What does your payroll process look like? (Manual data entry? Automated import?)

Step 2: Choose the Right Technology

Consider your business needs:

• Fixed location with all workers on-site: A fixed terminal with photo capture may be sufficient
• Multiple fixed locations: Mobile app with geofencing for each site
• Mobile or field-based workers: GPS clock-in with location tracking
• Mixed workforce: A platform that supports multiple clock-in methods

Step 3: Communicate the Change

Implementing time tracking technology can feel intrusive if not communicated well. Frame the change positively:

• It protects workers from underpayment and ensures accurate records
• It ensures fair treatment — everyone is held to the same standard
• It simplifies payroll and reduces errors
• It helps the business comply with employment law

Step 4: Set Clear Policies

Document your expectations:

• When workers should clock in and out
• What happens if they forget to clock in
• The process for correcting errors
• Consequences for deliberate time fraud
• How location data and photos will be used and stored (GDPR compliance)

Step 5: Train and Launch

Provide hands-on training for all workers. The system should be simple enough that training takes no more than 10–15 minutes. Provide a support channel for the first few weeks for any issues.

Step 6: Monitor and Refine

Review exception reports regularly in the first few months. Adjust geofence sizes, refine approval workflows and address any patterns of non-compliance promptly.

The ROI of Accurate Time Tracking

The return on investment from eliminating time theft and improving time accuracy is typically rapid:

• Reduced overpayments: Even a modest reduction in time inflation saves thousands annually
• Payroll efficiency: Automated time data eliminates manual entry, saving hours of admin time each pay period
• Labour cost accuracy: Reliable data enables better budgeting and resource planning
• Compliance confidence: Auditable records demonstrate WTR compliance
• Reduced disputes: When time records are transparent and verifiable, disputes between workers and managers decrease significantly

Most businesses report a full ROI within 2–4 months of implementing a modern time and attendance system.

Get Started with Accurate Time Tracking

Eliminating buddy punching and timesheet fraud is not about distrusting your workers — it is about building a fair, transparent system where everyone is held to the same standard and everyone is paid accurately for the time they work.
