Role Overview:
Process weekly and monthly payrolls accurately and on time, following agreed timetables, cut-off dates and approval controls. Collect, validate and process authorised pay elements and employee changes, including salary, hours, overtime, shift premiums, allowances, starters, leavers, back pay and final payments. Process PAYE, National Insurance, pensions, student loans, attachment orders, Direct Earnings Attachments, SSP, company sick pay, SMP and other statutory payments or deductions. Reconcile OneAdvanced Time and Attendance information to payroll; investigate missing clockings, unapproved hours, incorrect rates, duplicate payments and material pay variances before submission. Prepare payroll previews, control reports and gross-to-net reconciliations for HR Manager and Finance approval; no unsupported manual or retrospective adjustment may be processed. Complete payroll submissions, issue payslips, respond to employee queries and maintain clear records of corrections, overpayments and outstanding actions. Administer pension enrolment and contribution changes, upload pension files and reconcile employee and employer contributions to payroll. Produce payroll, headcount, overtime, absence, pension and deduction reports and reconcile payroll information to HR, Finance and pension records. Support payroll year-end, the new tax year, P60s, statutory reporting, internal and external audits, and maintain current payroll procedures and audit evidence. Administer the full employee lifecycle, including offers, contracts, right-to-work and pre-employment checks, onboarding, probation, employee changes, absence, family leave and leavers. Prepare accurate HR correspondence and ensure salary, job title, manager, department, cost centre, shift, hours and personal-information changes are supported and effective from the correct date. Administer holidays, sickness, fit notes and family leave, ensuring relevant information is approved, recorded and provided to payroll before cut-off. Maintain complete electronic employee files in accordance with confidentiality, access, naming, filing and retention requirements. Create, amend and close employee records across OneAdvanced HR, OneAdvanced Time and Attendance, TMS, Flexipay, SAP SuccessFactors and other approved systems. Complete regular system audits, correct authorised discrepancies and raise support tickets for interface, access or data-transfer issues. Ensure every employee or payroll amendment has an approval trail and is updated consistently across all affected systems. Coordinate approved recruitment from advertising and application management through interview, selection, offer, pre-employment checks and onboarding. Prepare vacancy adverts, interview documentation, candidate communications and offers only after the vacancy, salary and terms have been authorised. Maintain recruitment trackers and coordinate contracts, references, inductions, IT equipment, system access and internal announcements. Act as the HR administration contact for agencies on the Preferred Supplier List and maintain accurate records of leased personnel, assignments, rates, transfer dates and end dates. Check agency hours and invoice information against approved time records, resolve discrepancies and report on agency headcount, cost and transfer opportunities. Escalate unapproved headcount, rate changes, supplier changes or assignment extensions; the postholder may not agree new commercial terms independently. Support policy and procedure updates and, where suitably experienced, assist with investigations, disciplinary, grievance, capability and absence cases through letters, notes, case files and action tracking. Maintain strict confidentiality and individually assigned system access; do not process unsupported changes, and escalate complex employee relations, payroll, fraud, data protection or statutory matters to the HR Manager.
