Across the nuclear sector, long-standing personal service company arrangements are being squeezed by IR35 policy, risk appetite and internal procurement rules. In many cases the response is not a careful assessment of the working relationship, but a blanket move away from PSCs and outside-IR35 engagements. That may be administratively convenient, but it creates a real problem for an industry that cannot afford to lose experienced people.
The UK nuclear sector is trying to do a lot at once: defence, large-scale new build, small and advanced reactors, advanced fuels, decommissioning, fusion, maritime nuclear and more. Those programmes need people with scar tissue. People who understand regulated delivery, technical uncertainty, stakeholder pressure and the realities of getting difficult work done. Yet some of those people are being pushed towards structures that offer little more than payroll processing.
For many independent consultants, the default alternative is an umbrella company. That may tick a box, but it rarely provides a professional home. It does not build a consulting career. It does not create a peer group. It does not help the client retain capability in a more intelligent way. It often leaves the consultant carrying much of the insecurity of contracting, without the autonomy that made contracting attractive in the first place.
The gap NCL is closing
The Bring Your Own Client model is designed for exactly this situation: a trusted consultant, an existing client relationship, and a contracting route that has become the obstacle rather than the enabler.
The idea is simple. The consultant joins NCL as a PAYE consultant. The client contracts with NCL. The work continues with minimal disruption. The client retains the specialist they already trust, and the consultant moves into a genuine nuclear consultancy rather than a generic umbrella arrangement.
This is not about dressing up contracting as employment. It is about recognising that the industry needs better ways to retain scarce expertise when the old PSC model no longer works for everyone. For the consultant, BYOC offers continuity, employment benefits and access to a wider consulting platform. For the client, it provides a route to keep critical knowledge in the programme without continuing a PSC engagement that no longer fits internal policy. For the industry, it prevents another experienced specialist being lost to avoidable contracting friction.
The cultural point
Nuclear consulting is not commodity labour. The best consultants are not interchangeable CVs moving through a supply chain. They carry client knowledge, delivery judgement, technical context and hard-won credibility. When a working relationship is delivering value, the industry should be finding ways to preserve it, not forcing it through the least-worst payroll mechanism available.
That is why BYOC starts with a three-way conversation: consultant, client and NCL. Where there is a genuine relationship and a continuing requirement, NCL can provide the right consultancy structure around it. The aim is not to make life complicated. It is to keep good people doing valuable work, while giving both consultant and client a cleaner, more sustainable route forward.
If your client still wants you, but no longer wants your PSC, an umbrella company is not the only answer. Bring your expertise. Bring your relationship. Bring your client. NCL can provide the consultancy home around it.
