FCA-compliant LinkedIn content for UK financial advisers is content that either stays outside the FSMA 2000 section 21 financial promotion restriction or — when it falls inside it — has been approved through the firm's compliance process. In practice, most adviser LinkedIn content can be educational, factual or process-led without triggering the rule.
This guide is general industry information for UK FCA-authorised advisers, not legal or compliance advice. Your firm's policy and your compliance team take precedence over anything written here. Read the underlying FCA guidance directly: FG24/1 (financial promotions on social media), COBS 4, SYSC 9, and FSMA 2000 s21.
The four rules every UK adviser needs to know
Know what counts as a financial promotion
Under section 21 of the Financial Services and Markets Act 2000, a communication is a financial promotion when it is an invitation or inducement to engage in investment activity. Educational, factual or process-led content does not automatically meet that bar — but specific product mentions, performance claims and "buy/invest" calls almost always do.
In practice
A post explaining how ISAs work is generally fine. A post recommending a specific fund is a financial promotion and needs your firm's approval before it goes out.
Identify your firm clearly
Your LinkedIn profile should make your authorised status visible. Your firm name, your role and (where appropriate) the firm's FCA reference number give readers and the regulator a clear line of sight to your authorisation.
In practice
Headline + experience section should make it obvious you are advising under an FCA-authorised firm. Do not hide it behind generic job titles.
Apply Consumer Duty thinking to every post
Under the Consumer Duty (PRIN 2A), communications must be clear, fair and not misleading, and must support understanding for the audience seeing them. On LinkedIn, your audience is mixed — clients, prospects, peers — so write to the lowest reasonable level of financial literacy that could click on the post.
In practice
A post that a peer would understand but a retail client could misread is a Consumer Duty risk. Write so the least informed reader still gets the point right.
Keep records the way SYSC 9 requires
SYSC 9 requires regulated firms to retain communications relating to their regulated activities for a defined period. LinkedIn is not exempt. Your firm needs a way to retrieve what you posted, when, and to whom — including replies and DMs that touch advice.
In practice
Either your firm has an archiving solution (e.g. Smarsh, Erado, Global Relay) or you screenshot/export your posts on a schedule. Find out which before posting at volume.
What you can post versus what crosses the line
Most advisers worry about LinkedIn compliance because the line feels invisible. It is not. Educational, process-led and behavioural posts are generally outside the financial promotion regime. Specific recommendations, performance language and identifiable client details cross into territory that needs your firm's sign-off.
| Generally allowed | Avoid (or compliance approval first) |
|---|---|
Educational principles — "how ISA allowances work", "what diversification means in practice" | Specific product, fund or share recommendations |
Process explanations — "how I structure a retirement income plan" | "Buy this fund" / "DM me to invest" calls to action |
Behavioural insights — "the cost of emotional investing in volatile markets" | Performance guarantees, "risk-free" language, or returns claims |
Commentary on regulation, market structure or industry news | Backtested charts presented without risk warnings or context |
Anonymised illustrative examples ("a recent client situation showed…") | Identifiable client stories, names, or financial details without explicit consent |
Frameworks and questions — "three things to think through before drawing pension" | Predictions about specific markets, rates or asset prices presented as fact |
The 7-point pre-posting checklist
Run every LinkedIn post through this list before publishing. It takes 30 seconds and catches almost every common compliance issue.
Could this post be read as inviting someone to engage in investment activity? If yes, route it through your firm's compliance process before posting.
Does it name a specific product, fund, ticker or include performance numbers? If yes, treat it as a financial promotion by default.
Are any client situations or numbers identifiable? Anonymise, or get explicit written consent.
Is your authorised firm visible in your profile and (where required by your firm) in the post itself?
Is the language clear, fair and not misleading for the least informed reader who could see this?
Will your firm be able to retrieve this post — text, images and any replies that touch advice — if the regulator asks?
If anything above is uncertain, send to compliance. The cost of pre-approval is always lower than the cost of a retrospective issue.
Build a content rhythm that stays inside the lines
Calm Authority generates LinkedIn drafts in your own voice and biases the structure toward the three categories that almost always sit outside the financial promotion regime — educational, process-led and behavioural. You still review, edit and route anything promotional through compliance. The system removes the blank page, not the oversight.
