Robo-advisors have transformed UK investing by making professional portfolio management accessible and affordable. Instead of needing a traditional financial advisor (typically requiring £50,000+ in assets), you can get a managed, diversified portfolio from as little as £1.
How Robo-Advisors Work
- You answer a questionnaire — about your goals, timeline, risk tolerance, and experience
- The platform builds a portfolio — typically using low-cost ETFs across equities, bonds, and other asset classes
- Automatic management — the platform rebalances your portfolio, adjusts allocations, and reinvests dividends
- You contribute regularly — set up a direct debit and the platform handles the rest

Nutmeg
The UK’s largest robo-advisor (owned by JP Morgan). Offers three tiers:
- Fixed Allocation — cheapest, pre-set portfolios
- Fully Managed — actively adjusted by the investment team
- Socially Responsible — ESG-focused portfolios
Solid track record, good user interface, and a range of risk levels (1–10). The main downside is that fully managed fees (0.75% + fund costs) approach 1%, which is expensive for what is largely passive investing.
Wealthify
Owned by Aviva. Very low minimum investment (£1), making it ideal for beginners:
- Five risk levels: Cautious, Tentative, Confident, Ambitious, Adventurous
- Free plan available for basic ethical investing
- Simple, clean app and website
Slightly higher overall fee than some competitors, but the low barrier to entry and simplicity make it popular with new investors.
Moneyfarm
Italian-origin platform with a growing UK presence:
- Seven risk levels with more granularity than most competitors
- Includes access to a human investment consultant at no extra cost
- Active-like management with passive instruments
Fees reduce as your portfolio grows, starting at 0.75% for under £10,000 and falling to 0.35% for £500,000+.
InvestEngine
The most cost-competitive managed option:
- 0.25% management fee with a DIY option at 0% (free)
- ETF-focused portfolios
- Limited account types (no SIPP currently)
For cost-conscious investors who want managed portfolios, InvestEngine offers the best value.
Vanguard LifeStrategy (DIY Alternative)
Not technically a robo-advisor, but Vanguard’s LifeStrategy funds achieve a similar outcome:
- Five funds with fixed equity/bond splits (20%, 40%, 60%, 80%, 100% equity)
- Automatic rebalancing within the fund
- Total cost around 0.37% on Vanguard’s platform
- The simplest one-fund solution for DIY investors
Robo-Advisor vs DIY Investing
| Factor | Robo-Advisor | DIY Investing |
|---|---|---|
| Effort | Minimal — fully managed | More involvement needed |
| Portfolio construction | Professional | You choose your own funds |
| Rebalancing | Automatic | You do it yourself (or pick a LifeStrategy fund) |
| Cost | 0.35–0.95% total | 0.15–0.40% total |
| Control | Limited | Full |
| Best for | Hands-off investors, beginners | Cost-conscious, experienced investors |
The cost difference of 0.2–0.5% per year may seem small, but over 30 years on a £100,000 portfolio growing at 7%, it amounts to £30,000–£75,000 less wealth. Whether the convenience justifies this cost is a personal decision.
Who Should Use a Robo-Advisor?
Robo-advisors suit you if:
- You are new to investing and want guidance on portfolio construction
- You want a hands-off approach — set it and forget it
- You do not want to learn about asset allocation and rebalancing
- You value convenience over absolute cost minimisation
- You have a medium-sized portfolio — large enough for the fee to matter but small enough that a traditional advisor is not cost-effective
Who Should Invest Themselves?
DIY investing suits you if:
- You are comfortable selecting index funds and rebalancing your portfolio
- You want to minimise fees to keep more of your returns
- You enjoy learning about investing and want full control
- You are willing to spend 30–60 minutes per year reviewing and rebalancing
How to Choose
- Compare total fees — management fee + fund costs + any trading charges
- Check account types — do you need ISA, SIPP, LISA, or junior accounts?
- Review risk levels — ensure the platform’s options match your tolerance
- Try the questionnaire — most platforms let you see the recommended portfolio before committing
- Check minimum investment — some require £500+, others as little as £1
- Consider ethical options — if ESG investing matters to you, check what is available
