Robo-adviser vs DIY investing in the UK

Quick answer: Robo-advisers offer ready-made portfolios with low minimums and automated rebalancing, while DIY platforms give full control but require you to choose funds and manage risk yourself.
UK investors can use execution-only platforms, robo-advisers or full financial advice. Each route is regulated by the FCA but offers different levels of guidance and cost. This guide compares fees, suitability and when each approach fits.

What robo-advisers do
Robo services ask about goals, time horizon and risk tolerance, then place you in a model portfolio — often passive ETFs or index funds. Many rebalance automatically and offer ISA, pension and GIA wrappers.
They suit beginners who want hands-off investing but still need a defined risk level. They are not the same as personalised financial advice.
DIY platform advantages
DIY investing suits people who want to pick individual shares, active funds or thematic ETFs. Platforms like general investment accounts and ISAs from major UK brokers offer research tools and wide fund ranges.
You control tax harvesting, asset allocation and timing, but you are responsible for diversification and avoiding emotional trading. Without discipline, DIY investors often underperform simple index funds over the long term.
Fees and regulation
Compare platform fees, trading costs and fund ongoing charges. A 0.25% robo fee plus 0.15% funds may beat an expensive active fund on a DIY platform if you would otherwise pick high-charge products.
All providers must be FCA-authorised. Check the Financial Services Register and whether your assets are FSCS-protected if the firm fails.
Common questions
Is a robo-adviser giving me advice?
Usually it is guidance or execution-only portfolio management, not full personal advice on your overall finances.
Can I switch from robo to DIY later?
Yes. You can transfer ISAs and pensions or sell and rebuy in a new platform, using official transfer forms for tax wrappers.
Which is better for pensions?
Both offer SIPPs and personal pensions. Choose based on fund range, fees and whether you want automatic glidepaths as you approach retirement.
