Last reviewed: 11 May 2026. Robo-advisors are online investment platforms that use automated rules and model portfolios to manage your money. They sit between low-cost DIY index investing and traditional advised wealth management. In the UK in 2026, the leading robo-advisors charge 0.45% to 0.85% all-in (platform fee plus underlying fund costs) and offer ISAs, SIPPs, Lifetime ISAs, Junior ISAs, and General Investment Accounts. This guide explains how they work, who they suit, what the regulation looks like, how to choose between them, and where the limits lie.
TL;DR
- Robo-advisors automate investment portfolio construction based on a short risk questionnaire.
- Total annual cost is typically 0.45% to 0.85% of assets, materially lower than a traditional advised service (1.5% to 2%) but higher than DIY index investing (0.20% to 0.40%).
- Most UK robo-advisors are authorised as discretionary investment managers by the FCA and segregate client money under FCA CASS rules.
- Cover under the Financial Services Compensation Scheme is up to £85,000 per provider for investments, against provider failure or fraud (not investment losses).
- They are not the same as a regulated financial adviser. They do not provide personal financial planning advice on tax, retirement income, estate planning, or complex situations.
- For sub-£100,000 ISAs and SIPPs where the holder wants a hands-off setup, robo-advisors are usually competitive on price and simplicity.
How robo-advisors work
A robo-advisor asks you to complete a short suitability questionnaire covering investment goals, time horizon, income, capacity for loss, and risk tolerance. The platform then allocates your money to one of a small number of model portfolios, typically 5 to 10 risk levels each holding a mix of equity, bond, and sometimes property ETFs from major fund houses. Rebalancing is automated and happens either continuously or quarterly. Some providers offer themed portfolios such as ESG, retirement-targeted (with glide paths), fixed income only, or higher-yield income.
You can usually open and contribute to a robo-advised account in under 15 minutes. Funds are held in a stocks and shares ISA, SIPP, Lifetime ISA, Junior ISA, or General Investment Account depending on the provider. Most accept lump sums, monthly direct debits, and cash or in-specie transfers from other providers.
What's inside a typical robo portfolio
A balanced 60/40 portfolio at a major UK robo in 2026 might hold:
- Vanguard FTSE All-World UCITS ETF or similar global equity tracker (around 50% of equity sleeve)
- iShares Core MSCI Emerging Markets ETF (around 10% of equity sleeve)
- iShares Core UK Gilts ETF or equivalent (around 60% of bond sleeve)
- iShares Core Global Aggregate Bond ETF or hedged equivalent (around 30% of bond sleeve)
- iShares Index-Linked Gilts ETF (around 10% of bond sleeve)
- Optional REIT or property sleeve (0% to 5%)
The mix is rules-based, not discretionary stock-picking. Two robo-advisors using the same risk level will typically produce broadly similar returns over five-year periods.
Cost breakdown
| Cost layer | Typical range | Notes |
|---|---|---|
| Platform management fee | 0.25% to 0.45% | Usually tiered: lower above £100,000 or £250,000 |
| Underlying fund (OCF) | 0.15% to 0.35% | Higher for ESG or actively-tilted portfolios |
| Transaction costs | 0.05% to 0.10% | Embedded in fund prices, often not separately quoted |
| Total annual cost | 0.45% to 0.85% | Compare to traditional advised: 1.50% to 2.00% |
On a £50,000 ISA, a 0.65% all-in fee costs £325 a year. The equivalent DIY portfolio using a cheap broker plus a global tracker plus a gilt fund might run at 0.25% all-in, or £125 a year. The £200 annual difference is the price of automation, rebalancing, and the absence of platform admin.
Who robo-advisors suit
- First-time investors who want a hands-off setup with no DIY decisions.
- People with £500 to £100,000 to invest who do not want full wealth management.
- ISA savers who would otherwise leave the money in cash.
- Investors who value automated rebalancing and tax-loss harvesting (where offered in a GIA).
- People who want a clean monthly direct debit and no admin between contributions.
- SIPP holders building retirement balances over decades who want a default glide path.
Who is better served elsewhere
- DIY investors comfortable with index funds: a low-cost platform with a global tracker plus a gilt fund typically costs 0.20% to 0.40% all-in. Over 30 years the fee difference compounds materially.
- High net worth investors (£500,000+): bespoke wealth management or a discretionary portfolio service may offer better value once fees are negotiated, alongside personalised tax planning.
- Anyone with complex needs: tax planning across multiple wrappers, defined-benefit transfers, business sale proceeds, divorce settlements, inheritance, or estate planning need a regulated financial planner, not a robo.
- People who actively want to pick funds: a self-directed platform gives full control.
- People nearing retirement decumulation: Robos are better-built for accumulation than for drawdown income planning, although some now offer drawdown-aware portfolios.
Risk and regulation
UK robo-advisors are authorised and regulated by the FCA, typically as discretionary investment managers under permissions for "managing investments" and "safeguarding and administering investments". Client money is held under FCA CASS (Client Assets Sourcebook) rules in segregated trust accounts at major UK custodian banks. If the provider fails, the Financial Services Compensation Scheme covers eligible investments up to £85,000 per person per authorised firm.
Note that FSCS does not protect you from investment losses. If the underlying funds fall in value, that is part of normal market risk. FSCS only protects against provider failure or fraud. Check the provider's FCA reference number on the Financial Services Register before opening an account.
What to look for when choosing
- Total annual cost: Platform fee plus underlying fund OCF. Anything above 0.85% combined is uncompetitive in 2026.
- Number of risk levels: More granular options (10 levels) give better alignment than coarse ones (5 levels). At the extremes, very cautious or very aggressive investors are sometimes underserved by 5-level systems.
- Account types offered: ISA, SIPP, LISA, JISA, GIA. Confirm the wrapper you need is supported and that transfers in are accepted.
- Minimum investment: Some providers require £100, others £1,000 or £5,000. Some have higher minimums for SIPPs.
- Transfer-in process: Most accept cash and in-specie ISA transfers; some are noticeably slower than others. Six-week transfer windows are common; some take longer.
- Customer support: Some offer access to qualified financial planners for an additional fee, useful for one-off questions at major life events.
- Tax statement and reporting: All UK robos provide an annual tax statement. Quality varies; check the statement format if you're a higher-rate or additional-rate taxpayer.
- ESG and themed portfolios: If you want an ESG portfolio, check the screening methodology rather than the marketing copy.
- Drawdown and decumulation support: If approaching retirement, ask specifically how withdrawals are handled and whether the portfolio adjusts as you draw down.
Tax treatment
Investments held in an ISA or SIPP are tax-sheltered. Investments held in a General Investment Account are subject to UK Capital Gains Tax above the annual allowance (£3,000 for 2025-26 tax year, expected to remain at £3,000 for 2026-27) and income tax on dividends above the £500 dividend allowance. Robo-advisors usually provide a tax statement annually but do not file your tax return for you.
For larger GIA balances, tax-loss harvesting (selling and replacing positions to crystallise losses against gains) can be valuable. A handful of UK robos offer this; most do not. If you have a GIA above £50,000 and want this feature, confirm it before signing up.
Performance: what to expect
A balanced 60% equity, 40% bond portfolio in GBP terms has produced roughly 5% to 7% annualised total return over the past 20 years, with substantial year-to-year variability. Cautious portfolios (30/70 equity/bond) tend to produce 3% to 5%; aggressive portfolios (90/10) produce 7% to 9%. These are pre-fee figures. After 0.65% all-in costs and inflation, real returns are materially lower.
Robo-advisor portfolios are designed to track this kind of long-term outcome. They are not designed to beat the market. If you want active management or tactical asset allocation, a robo is not the right product.
Frequently Asked Questions
Is a robo-advisor the same as a financial adviser?
No. A regulated financial adviser provides personalised advice and carries liability for that advice. A robo-advisor provides a discretionary investment service based on your risk profile but does not advise on your wider financial situation, tax position, retirement plan, or estate.
What happens to my money if the robo-advisor fails?
Your investments are held in a separately ring-fenced custody account, so they are not part of the firm's assets. The administrator transfers your holdings to another provider. FSCS covers up to £85,000 per person if there is a shortfall in cash or securities held by the firm.
Can I withdraw whenever I want?
Yes, subject to standard settlement times (T+2 for equities and ETFs, T+1 for gilts). Withdrawals from an ISA do not affect your contribution allowance for the tax year unless the provider supports flexible ISA rules and you re-deposit within the same year.
Do robo-advisors offer ESG options?
Most major UK robo-advisors now offer at least one ESG-screened portfolio range. ESG funds typically cost 0.10% to 0.20% more than the standard equivalent, and the screening methodology varies widely between providers.
What's the difference between a robo SIPP and a workplace pension?
A workplace pension is set up and contributed to by your employer with a default fund. A robo SIPP is opened by you and funded by you, with portfolio selection based on your risk profile. Both are tax-relieved at your marginal rate; a workplace pension also benefits from employer contributions, which a SIPP does not. For most employees, the workplace pension is the priority; a SIPP is a useful addition for self-employed people or those wanting more control.
Can I have both a robo-advisor and a DIY platform?
Yes. There is no rule against having multiple platforms. Many investors split between a robo (for set-and-forget core) and a DIY platform (for satellite positions or specific products like investment trusts). Watch your overall ISA contribution limit and SIPP annual allowance.
