Timesheet management is the process of recording, reviewing and approving the hours employees work. Accurate timesheets are essential for correct payroll processing, compliance with working time legislation and controlling labour costs.

Why Timesheets Matter

PurposeDetail
Payroll accuracyEnsures employees are paid correctly for hours worked, including overtime
Legal complianceDemonstrates compliance with the Working Time Regulations 1998
National Minimum Wage / NLWProves total pay ÷ total hours ≥ minimum wage
Holiday accrualCalculates holiday entitlement for irregular hours workers (12.07% of hours worked)
Project costingAllocates labour time to specific projects or clients
Overtime managementTracks hours above contracted working hours
Absence trackingRecords sickness, statutory sick pay periods, holiday and other leave

Working Time Regulations

Under the Working Time Regulations 1998, employers must ensure workers do not exceed an average of 48 hours per week (calculated over a 17-week reference period, unless the worker has opted out in writing). Employers must keep records that are adequate to show compliance and retain them for 2 years.

National Minimum Wage Records

Employers must keep sufficient records to demonstrate NMW/NLW compliance for 3 years. For hourly-paid and piece-rate workers, this requires accurate records of hours worked.

EU Working Time Directive (Retained Law)

Following the CJEU ruling in CCOO v Deutsche Bank (2019), there is a requirement to have a system capable of measuring daily working time. While the UK has departed the EU, the ruling influenced UK practice, and employers are expected to record working hours to demonstrate compliance.

Timesheet Process

A typical timesheet workflow:

  1. Employee records hours — daily or per shift, noting start time, end time and breaks
  2. Employee submits timesheet — at the end of the pay period (weekly, fortnightly or monthly)
  3. Manager reviews and approves — checks hours against schedules, overtime authorisation and absence records
  4. Payroll processes approved hours — calculates gross pay, overtime, statutory pay and deductions
  5. Records are retained — for at least 2 years (Working Time Regulations) or 3 years (NMW)

Overtime and Timesheets

Timesheets are essential for tracking overtime, which has direct payroll implications:

Overtime TypeDetail
Guaranteed overtimeContractually required and included in regular pay calculations
Non-guaranteed overtimeOffered at the employer’s discretion but must be worked if offered
Voluntary overtimeEmployee chooses whether to work it

Overtime rates and conditions should be specified in the employment contract . For holiday pay calculations, regular overtime (both guaranteed and non-guaranteed) must be included in the 52-week reference period calculation.

Timesheets and Payroll Integration

Accurate timesheets feed directly into PAYE payroll :

Timesheet DataPayroll Calculation
Regular hoursGross salary
Overtime hoursOvertime pay at the applicable rate
Absence hoursSSP , SMP , unpaid leave
Holiday hoursHoliday pay calculation
Total hoursNMW/NLW compliance check

Modern payroll software can import timesheet data directly, reducing manual entry and the risk of errors. The approved hours flow through to:

Agency Workers and Timesheets

For agency workers, the employment agency or the hirer (depending on the arrangement) is responsible for recording hours. The hirer typically approves timesheets, and the agency processes payroll. Under the Agency Workers Regulations 2010, agency workers are entitled to the same basic working conditions (including pay) as comparable direct employees after 12 weeks in the same role.

Timesheets and Accounting

Labour costs recorded through timesheets feed into the employer’s accounting records :

AccountSource
Wages and salariesTotal hours × hourly rate
Overtime expenseOvertime hours × overtime rate
Project labour costsHours allocated to specific projects
Work in progressLabour time on unbilled client work
Accrued wagesApproved hours not yet paid at period end

For businesses that bill clients based on time (such as consultancies and professional services), timesheets directly determine revenue recognition and project profitability.

Common Timesheet Errors

ErrorImpact
Missing break deductionsOverpayment of hours; potential NMW compliance issue
Unapproved overtimeUnexpected payroll costs
Late submissionsDelayed payroll processing; employees paid late
Incorrect project codesMisallocated labour costs; inaccurate project profitability
Rounding errorsSystematic over- or underpayment
Not recording all working timeNMW/NLW non-compliance risk
