Legal Adviser (non-regulated) in Northern Ireland
Non-reserved commercial guidance. This guide covers the rules, taxes and compliance points that apply specifically when operating in Northern Ireland.
What a legal adviser (non-regulated) actually does
As a Legal Adviser (non-regulated) in the UK, you typically expert advisory, consulting or operational services that help other businesses run better. Day-to-day work focuses on non-reserved commercial guidance while keeping on top of UK tax, insurance and compliance rules.
Your duties include, but are not limited to:
- Scoping engagements and writing SOWs
- Delivering advice or consulting work
- Reporting progress to clients
- Tracking billable hours or deliverables
- Managing confidential client data
- Invoicing on agreed payment terms
How you operate
Mostly remote or hybrid, often invoicing clients monthly. Many start solo and bring in associates as work scales.
Who you work with
SMEs, scale-ups, public sector buyers, recruitment partners and other consultancies. Long-term retainers are common.
How you earn
Day rates, fixed-scope project fees and monthly retainers. Some also earn referral or finder's fees.
Key compliance areas
Written services agreements, IR35 status reviews per client, Professional Indemnity Insurance and ICO registration if processing personal data.
Why compliance matters
An incorrect IR35 determination can shift PAYE liability onto you. Working without PI cover exposes personal assets to client claims.
Business tip
Run separate Statements of Work per project, even with the same client — it keeps scope, IR35 status and invoicing crystal clear.
