Set up the smallest lawful business that can learn from a real buyer. Describe the activity and location first; then check restrictions, choose a proportionate structure, register what is required, separate the money and run one bounded customer test.
The order before the forms
What exactly will the business do, for whom and where?
Activity and location reveal licences, consumer duties, insurance and tax questions that a generic checklist misses.
What risk, ownership or customer requirement makes a structure consequential?
The wrapper should answer a real exposure or operating need rather than founder identity.
What buyer behaviour would justify the next irreversible cost?
A pre-written evidence threshold keeps administration from becoming validation theatre.
| First | Then | Keep visible |
|---|---|---|
| Define activity, owners and location | Check licences, insurance and employment constraints | Questions requiring an accountant, solicitor or regulator |
| Compare structures | Register with the correct authority | Filing, tax and recordkeeping dates |
| Separate money and records | Put contracts, privacy and consumer controls in place | One first-customer test and its stopping rule |
Frequently asked questions
A company is only one route. GOV.UK says a sole trader can start trading before Self Assessment registration becomes due, but activity-specific duties can arise earlier.
It depends on the activity, location, people and risks involved. Use the official licence finder and insurance guidance before the relevant transaction.
Write the business activity, structure reason, mandatory obligations and buyer-evidence threshold. Pay only for what the next responsible test requires.
