Compliance checks for sole traders
Guidance on tax obligations, invoicing and record keeping, including the apprenticeship levy where it applies

The global wind sector is projected to need hundreds of thousands of additional skilled workers this decade — here is how a UK contractor gets into offshore work without falling foul of the compliance requirements.
Offshore wind, decommissioning and subsea cabling are all scaling at once, and all three compete for the same technical skills. The shortage is not of people willing to work offshore; it is of people who can be mobilised compliantly at short notice.
That is good news for a contractor who prepares in the right order.
Certification is the usual bottleneck, and it is the one part that cannot be compressed once an opportunity appears. Booking survival and medical training before an offer exists is what turns a two-month lead time into a two-week one.
The same is true of status: knowing how you will be engaged, and having a compliant provider already in place, removes the delay that costs most contractors the first offer.
We employ offshore contractors directly, which closes the status question for the operator and gives the contractor continuous employment across assignments and operators.

leads contractor payroll operations at Promultis
Daniel Okafor runs the payroll operation that pays several thousand contractors every week, and he built most of it. He joined Promultis from a large umbrella provider, where he was responsible for RTI submissions and auto-enrolment across a book of forty agencies. Daniel works closely with recruitment partners on onboarding, same-day payments and the reporting hirers need for their own audits. He writes about the practical side of contractor engagement — the parts that decide whether a worker stays past their first assignment.
