Frequently asked questions about the United Kingdom
Running payroll and HR in the United Kingdom means keeping up with HMRC deadlines, RTI submissions, auto-enrolment rules and ever-changing employment law. Below we’ve answered the questions employers ask us most often about outsourcing payroll and HR support in the UK.
What does outsourced payroll in the United Kingdom include?
Outsourced payroll in the United Kingdom typically covers monthly payroll processing, PAYE and National Insurance calculations, RTI submissions to HMRC, payslip distribution, auto-enrolment pension contributions, and year-end reporting including P60s and P11Ds. At Black Mountain, we handle all of this in-house so employers in the United Kingdom stay fully compliant without the admin burden.
Do you handle auto-enrolment and workplace pensions in the United Kingdom?
Yes. Every employer in the United Kingdom must automatically enrol eligible workers into a qualifying workplace pension and make contributions. We manage the full auto-enrolment process, assessing your workforce, enrolling eligible employees, processing contributions, handling opt-outs, and completing the required re-declaration of compliance with The Pensions Regulator.
How much do outsourced payroll services cost in the United Kingdom?
Costs vary depending on employee headcount, pay frequency and whether you need HR support alongside payroll. Most small and mid-sized employers in the United Kingdom pay a fixed monthly fee based on the number of payslips processed. Contact us for a tailored quote, there are no setup fees and no long-term contracts.
How long does it take to switch payroll providers in the United Kingdom?
A payroll transition in the United Kingdom typically takes two to four weeks, depending on your pay cycle and complexity. We handle data migration from your existing provider, parallel-run the first payroll to check accuracy, and manage the HMRC handover. Most switches happen at the start of a new tax month or tax year for a clean cut-over.
Can you support small businesses and startups in the United Kingdom?
Yes. We support employers of all sizes across the United Kingdom, from businesses running their first payroll to organisations with hundreds of employees. For small businesses and startups, outsourcing removes the need to learn HMRC systems, buy payroll software or hire in-house payroll staff, you get expert support from day one.
Do you provide HR support alongside payroll in the United Kingdom?
Yes. Alongside payroll, we provide integrated HR services across the United Kingdom including employment contracts, employee handbooks, HR advisory, absence management and compliance with UK employment law. Combining payroll and HR under one provider gives employers a single point of contact and ensures data flows seamlessly between the two functions.
