InvestEngine edges out Public.com as the overall winner, scoring 3.2/5 versus Public.com's 3.0/5 on our independent rating. With FCA regulation, a free Stocks and Shares ISA, zero deposit and withdrawal fees, and both web and mobile platform access, InvestEngine delivers a more complete and better-regulated experience for UK-based investors. Public.com holds its own with a broader asset range that includes crypto, but for most retail investors prioritizing safety, low costs, and portfolio management tools, InvestEngine is the stronger pick.
When it comes to investor protection, the regulatory framework behind a broker is arguably the most important factor to evaluate. InvestEngine is regulated by the Financial Conduct Authority (FCA) in the United Kingdom, one of the most respected and stringent financial regulators in the world. FCA oversight means InvestEngine must adhere to strict capital adequacy requirements, client money segregation rules, and transparent reporting obligations — all of which translate directly into a safer environment for retail investors.
Public.com, headquartered in New York, USA, operates under the supervision of the Securities and Exchange Commission (SEC). The SEC is a well-established regulator with broad authority over securities markets in the United States. While SEC regulation is credible and meaningful, the FCA's specific retail investor protections — including access to the UK Financial Services Compensation Scheme (FSCS) which covers up to £85,000 per eligible claimant — give InvestEngine a tangible safety advantage for UK-based users.
For US-based investors, Public.com's SEC regulation is entirely appropriate and provides solid baseline protections. However, in a direct regulatory strength comparison, InvestEngine's FCA licensing earns it higher marks on our safety scale, contributing to its overall rating advantage of 3.2/5 versus Public.com's 3.0/5. Neither platform offers leverage trading (both are capped at 1:1), which further underscores their positioning as responsible, long-term investing platforms rather than speculative trading venues.
Both InvestEngine and Public.com have built their core value propositions around commission-free investing, and in this regard, both platforms deliver. Neither charges trading commissions on stock purchases, and both platforms report spreads from 0 pips. Additionally, neither platform levies deposit or withdrawal fees, meaning investors can move their money in and out without incurring unnecessary costs. For cost-conscious retail investors, this is a significant and genuine advantage shared by both brokers.
Where InvestEngine differentiates itself is in the added value it layers on top of the zero-commission model. InvestEngine offers a free Stocks and Shares ISA, which is a tax-efficient account wrapper available to UK residents. This means eligible investors can hold ETF investments within an ISA without paying UK capital gains tax or income tax on returns — a benefit worth hundreds or even thousands of pounds annually for consistent investors. No equivalent tax-sheltered account structure is offered by Public.com, which is understandable given its US-market focus.
InvestEngine's managed portfolio service also operates with notably low ongoing charges compared to traditional robo-advisors or fund managers. For do-it-yourself investors, the self-directed account is entirely free to use. Public.com does not charge for its core investing features either, though premium features and certain advanced tools may carry associated costs. On pure fee structure alone, InvestEngine holds a meaningful edge, particularly for UK investors seeking tax-efficient, low-cost long-term wealth building.
This is the one category where Public.com clearly outperforms InvestEngine. Public.com supports two primary market types — Stocks and Crypto — giving investors the ability to access both traditional equity markets and digital asset markets from a single platform. For investors who want exposure to cryptocurrencies like Bitcoin or Ethereum alongside their stock holdings, Public.com provides a convenient, unified experience without needing to open separate accounts on dedicated crypto exchanges.
InvestEngine, by contrast, focuses exclusively on Stocks — specifically Exchange-Traded Funds (ETFs). This focused approach is a deliberate strategic choice rather than an oversight. ETFs are widely regarded as one of the most efficient, diversified, and cost-effective investment vehicles available to retail investors, and InvestEngine has built its entire platform around making ETF investing as simple and affordable as possible. For investors who believe in passive, index-based investing, InvestEngine's library of ETFs is genuinely comprehensive.
However, the absence of individual stock picking, crypto assets, options, or bonds on InvestEngine does limit its appeal for investors seeking a broader, more active investment approach. If your investing philosophy centers on diversified ETF portfolios and tax-efficient long-term growth, InvestEngine's focused offering is a strength. If you want to dabble in crypto, hold individual equities, or explore alternative assets, Public.com's wider market coverage makes it the more versatile choice.
InvestEngine supports two platforms: a proprietary web-based interface and a proprietary mobile application. Having both a desktop and mobile experience gives investors the flexibility to manage their portfolios from any device, whether they prefer the larger screen real estate of a browser-based interface for in-depth portfolio reviews or the convenience of mobile for quick account checks and contributions. The InvestEngine web platform is clean, intuitive, and designed with simplicity in mind — making it particularly accessible for beginner and intermediate investors.
Public.com, on the other hand, is primarily a mobile-first platform, offering a proprietary mobile application as its main trading interface. The app is well-designed, visually engaging, and has developed a reputation for its social investing features, which allow users to see what other investors on the platform are buying and selling. This community-driven approach adds an interesting social dimension to investing that InvestEngine does not replicate. For younger, mobile-native investors, Public.com's app experience may feel more natural and engaging.
That said, the absence of a dedicated web platform for Public.com is a notable limitation for investors who prefer to conduct detailed portfolio analysis on a full-sized screen. InvestEngine's dual-platform offering earns it higher marks in this category, providing greater flexibility without sacrificing usability. Our platform assessment gives InvestEngine the edge here, which is reflected in its support for two platforms versus Public.com's single mobile offering.
InvestEngine offers a range of account types tailored to different investor needs, including a self-directed investment account, a managed portfolio account, and crucially, a Stocks and Shares ISA. The ISA offering is a standout feature for UK investors and is provided completely free of charge — a distinction that sets InvestEngine apart from many competitors who charge ISA management fees. The managed portfolio option is particularly well-suited to beginners who want professional-grade portfolio construction without paying traditional wealth management fees.
Public.com is designed primarily for US retail investors and offers standard individual brokerage accounts with access to stocks and crypto. The platform's social investing layer — where users can follow other investors, see popular holdings, and engage with a community of like-minded individuals — makes it an interesting choice for newer investors who benefit from peer learning and community engagement. However, it lacks the structured, goal-based investing tools that InvestEngine provides through its managed portfolio service.
For UK-based investors, InvestEngine is the clear winner on account type variety and tax efficiency. For US-based investors who want a socially engaging, mobile-first platform with crypto access, Public.com offers a compelling and appropriately regulated option. Neither platform is well-suited to professional or high-frequency traders — both are explicitly designed for long-term, buy-and-hold retail investors with a 1:1 leverage cap confirming this positioning.
After a thorough evaluation across regulation, fees, platform quality, asset coverage, and account types, InvestEngine emerges as the stronger broker overall, earning our rating of 3.2/5 compared to Public.com's 3.0/5. The FCA regulation, free ISA account, dual-platform availability, and laser-focused ETF investing experience make InvestEngine a particularly powerful choice for UK-based retail investors looking to build long-term wealth in a tax-efficient, low-cost manner.
Public.com is not without its merits. Its broader asset coverage — particularly the inclusion of cryptocurrency — its socially engaging mobile app, and its SEC-regulated structure make it a credible option for US-based investors who want a modern, community-driven investing experience. If crypto access or social investing features are high on your priority list, Public.com deserves serious consideration.
Ultimately, the right choice depends on your location, investment goals, and preferred experience. UK investors focused on ETF-based, tax-efficient long-term investing will find InvestEngine hard to beat. US investors seeking a broader, more social mobile investing platform may prefer Public.com. For pure overall value, safety, and platform completeness, however, InvestEngine takes the crown in this matchup.
