Payroll built around the rules that govern it.
Compliance isn't an add-on feature for us — it's the foundation of how our payroll administration is structured. Clear documentation, correct deductions, and processes aligned with UK payroll and tax requirements.
How we approach compliance and structured payroll administration
Rockwool Umbrella Solutions was established to provide payroll administration that operates correctly — not just commercially, but structurally. That means building processes around the legislation and HMRC requirements that govern CIS and PAYE umbrella payroll in the UK.
We don't make compliance claims we can't support. We don't invent accreditations or memberships. We describe our approach clearly: structured administration, transparent processes, and documentation that contractors and agencies can rely on.
The framework we operate within is established by HMRC and UK employment law. Our job is to administer payroll within that framework — accurately, consistently, and without confusion.
Alignment with UK payroll and tax frameworks
The payroll frameworks we work within are established by UK legislation and administered by HMRC. Here is how our operation aligns with each.
Construction Industry Scheme (CIS)
HMRCThe CIS framework is administered by HMRC and governs how deductions are made from subcontractor payments in the construction sector. Our CIS payroll administration is structured to align with current HMRC requirements — verifying registration, applying correct deduction rates, and maintaining records as required.
PAYE and Umbrella Employment
PAYEUmbrella employment operates under the standard PAYE system, governed by UK employment law and HMRC payroll requirements. We process income tax and National Insurance contributions correctly through PAYE, with full payslip documentation issued to workers on every payment cycle.
National Minimum Wage
Employment LawWorkers engaged through our umbrella service are employed under UK employment law. National Minimum Wage requirements apply and are incorporated into our employment framework. We do not structure arrangements that would result in workers receiving below the applicable minimum wage.
IR35 and Off-Payroll Working
IR35IR35 is complex legislation that affects how contractors are taxed. We do not make IR35 assessments on behalf of contractors or their end clients — this is the responsibility of the engaging party. Where a worker is assessed as inside IR35, our PAYE umbrella structure may be appropriate. Contractors should seek independent professional advice on their IR35 position.
What clear process looks like in practice
We believe that transparency in payroll is not optional — it's a basic requirement. These are the specific commitments we make to every contractor and agency we work with.
Clear payslips every cycle
Every worker receives a payslip that breaks down gross income, deductions, and net pay. No line item is left unexplained.
Disclosed margins and fees
Our umbrella margin and any applicable fees are disclosed to workers before engagement and shown on every payslip. No hidden charges.
Documented deduction records
CIS deduction statements are issued alongside payslips and retained. Workers have the documentation they need for their own HMRC submissions.
Questions answered directly
When contractors or agencies have questions about a payslip, a deduction, or a payment, we answer them. We don't redirect to terms and conditions.
HMRC registration verified
For CIS, we verify subcontractor registration with HMRC before processing any payment. The correct rate is applied from day one.
Agency reporting
Agencies receive confirmation of payment run completion and can access the information they need to manage their workforce payments confidently.
What we do not do
Setting out what we do not do is as important as describing what we do. Professional boundaries matter — particularly in a sector where non-compliant payroll practices cause real harm to workers.
