01What a robo-adviser actually does
You answer a risk questionnaire; an algorithm assigns you a ready-made diversified portfolio (typically cheap index funds), invests contributions automatically and rebalances. Some services hold a regulated advice permission for that narrow recommendation; others are "non-advised" — execution with helpful framing. All-in costs commonly run 0.4–1% a year including funds — versus roughly 1.5–2%+ all-in for full human advice with ongoing management, and £0 for pure DIY on a platform.
02The honest comparison
| Robo | Human adviser | DIY | |
|---|---|---|---|
| Cost (typical, all-in) | 0.4–1%/yr | 1.5–2%+/yr ongoing, or fixed fees | Platform + fund costs only |
| What it solves | "Invest this sensibly without me learning portfolio theory" | Whole-life planning: tax, pensions, estates, retirement income, behaviour | Anything — if you do the work |
| Blind spots | Knows only the questionnaire: no tax planning, no "should I pay the mortgage instead?", no DB pensions, no estates | Cost; quality varies by firm; minimum asset levels often apply | You are the blind spot — behaviour gaps cost real money |
| Protection | FCA-regulated; FOS/FSCS apply per the service's permissions | Full advice protections — suitability is legally theirs | Execution protections only; decisions are yours alone |
03The decision, by problem type
- Accumulating monthly into a S&S ISA or pension with simple affairs: robo (or DIY with one global fund) covers most of it — the value of full ongoing advice here is mostly behavioural coaching, which is real but expensive.
- Crossing a complexity threshold — retirement income, DB transfers, inheritances, divorce, tax cliff edges: the questionnaire cannot see your life. This is human territory, often as one-off fixed-fee work.
- Hybrid is normal, not cheating: robo or DIY for the simple accumulating middle, a paid human for the occasional big decision. Many "robo" firms now sell exactly this laddering, with human advisers on call.
04Common questions
Are robo-advisers safe?
Mainstream UK robo services are FCA-regulated, hold your investments in the usual segregated structures, and carry FOS/FSCS protections appropriate to their permissions. "Safe" never means market losses can't happen — your portfolio still moves with markets; that's the product working, not failing.
Do robo-advisers beat human advisers on returns?
Wrong scoreboard. Both typically allocate to similar diversified funds — gross returns converge. The differences are cost (robo wins), scope (humans win enormously), and behaviour management (depends on you). Compare them on the problem you're hiring for, not on last year's percentage.
Why does this site not recommend a specific robo-adviser?
Because naming "the best" regulated product is a financial promotion and adjacent to advice — outside our lane by design. We explain the category; the FCA Register and the firms' own fee pages let you compare specifics, and our investing basics guide covers the concepts the questionnaire glosses over.
