What 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.
The 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 |
The 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.
Same rules, same checks
A robo-adviser is just an FCA-authorised firm with an app. Check it on the FCA Register like anyone else, understand whether you're getting "advice" or "no advice" (it changes your complaint rights), and read the all-in fee line — some digital services aren't as cheap as the branding implies. The vetting toolkit applies unchanged.
