Highlights

• Identified a critical pension enrolment error affecting an accounting practice’s payroll client, where employees eligible for the NHS Pension Scheme had been mistakenly enrolled in NEST
• Immediately halted incorrect submissions to prevent further impact
• Reconciled five months of misdirected pension contributions across multiple payroll cycles
• Overcame NEST’s system constraints to reverse and correct historical submissions
• Fully restored accurate NHS Pension Scheme records with a complete, auditable trail

Introduction

Accounting practices that manage payroll on behalf of their own clients carry a particular kind of responsibility — any error doesn’t just affect one business; it ripples through to the employees of the clients they serve. One such accounting practice relied on Corient’s payroll outsourcing team to manage payroll processing for one of its clients, including complex NHS Pension arrangements, expecting precision in every cycle.

That’s where Corient stepped in — not just to process payroll, but to catch and correct an error before it grew into something far more damaging for the practice and the client they served.

The Initial Problem: What Went Wrong?

While processing the accounting practice’s April 2026 pension submissions, Corient’s team identified a serious discrepancy:

• Employees enrolled in the NHS Pension Scheme had instead been submitted through the NEST Pension portal
• This misrouting had been happening since November 2025, spanning five full payroll cycles
• Left unresolved, it would have meant continued incorrect pension records and growing compliance exposure

Corient informed the client of the issue immediately and stopped any further NHS Pension contributions from being submitted through NEST.

Corient’s First Solution: The Fix

Corient’s team began by reviewing every affected payroll period to understand the full scope of the error. This meant tracing each employee’s contribution history from November 2025 onwards and identifying exactly where and how the misclassification had occurred.

Reconciling the variances required examining each payroll cycle individually and comparing what had been submitted to NEST with what should have gone to the NHS Pension Scheme from the point of enrolment.

The New Problem: A Surprise Roadblock

While the scope of the error was now clear, correcting it wasn’t straightforward.

NEST’s system doesn’t easily allow previously closed contribution periods to be reopened. Five months’ worth of historical submissions needed to be corrected, but the portal simply wasn’t designed to handle corrections that far back — creating a real risk that the fix itself could introduce new inconsistencies if not handled carefully.

Corient’s Second Solution: Fixing the New Problem

1. Reopen the Affected Periods: Corient’s team worked within NEST’s system constraints to reopen each relevant contribution period from November 2025 to March 2026.
2. Reverse the Incorrect Contributions: Each affected employee was resubmitted with a zero pension contribution in NEST, effectively reversing the incorrect entries while preserving a clean record of the change.
3. Validate Against Enrolment Dates: Every reversal was cross-checked against the employee’s actual NHS Pension Scheme enrolment date, ensuring the correction accurately reflected when contributions should have started.
4. Reconcile and Balance: All pension reports for the affected period were fully reconciled, confirming that every reversed NEST entry and reinstated NHS Pension record balanced correctly.

The Final Outcome: Success Story

By the end of the process, Corient had:

• Corrected all affected pension records from November 2025 to March 2026
• Reversed every incorrect NEST submission accurately
• Restored NHS Pension Scheme enrolment to reflect each employee’s correct start date
• Fully reconciled and balanced all pension reports

“We didn’t just want the numbers patched — we needed to know exactly what had gone wrong and exactly how it was fixed. Corient’s team was transparent throughout, and the reconciliation gave us complete confidence in our client’s pension records again.”

Key Takeaways: Why This Matters for Businesses

• Small enrolment errors can compound quickly if not caught early
• Immediate containment prevents a payroll issue from growing further
• Historical corrections require a careful, auditable, step-by-step approach
• Specialist payroll oversight protects both compliance and employee trust

If pension accuracy matters to your business, don’t leave it to chance — work with a partner who catches the details before they become problems.
