UKIZ/CHECKLIST
Building in Britain,
in order.
Most of what goes wrong early is sequencing: raising before checking eligibility, structuring the group before understanding the permanent establishment condition, approaching investors before knowing which ones are relevant.
Twelve steps
01 — Understand the UK opportunity
Establish honestly whether Britain has the research, customers and capital your specific company needs — and where it does not.
02 — Decide company structure
Most investor-backed companies are UK private companies limited by shares. Group structures with an overseas parent can complicate tax-advantaged investment.
