CMC Invest combines commission-free UK and US share trading with transparent monthly plans backed by FTSE 250-listed CMC Markets, though foreign shares incur a 0.99% currency markup on the free plan.
CMC Markets was founded in London in 1989 by Peter Cruddas as a foreign exchange broker before expanding into spread betting and contracts for difference. The parent holding company, CMC Markets plc, completed its listing on the London Stock Exchange in 2016 (ticker CMCX). In 2022, the group launched CMC Markets Investments Limited under a separate Financial Conduct Authority license (FRN 948126) to deliver non-leveraged retail share trading and tax-sheltered accounts. Client securities are held under an insulated nominee structure, segregating long-term retail investments from the group's legacy trading activities.

Best for UK beginners and passive investors seeking £0 commission regular investing in UK shares and domestic index ETFs.
Active daily stock traders needing complex technical charting or international investors residing outside the UK.
Regulated by the UK FCA with £85,000 FSCS coverage and the institutional balance sheet of an LSE-listed parent firm.
CMC Invest operates through CMC Markets Investments Limited, authorized by the Financial Conduct Authority (FCA, FRN 948126) since March 2022. You can check each licence yourself on the FCA Register before opening an account. Because your investments fall under standard UK client asset segregation rules, your uninvested cash and custodial holdings remain strictly ring-fenced from the operational funds of the broker.
Eligible UK clients qualify for up to £85,000 in statutory compensation under the Financial Services Compensation Scheme (FSCS) should the brokerage fail. While the dedicated share dealing arm launched recently, its parent firm CMC Markets plc was established in 1989 and trades publicly on the London Stock Exchange (ticker CMCX). This corporate structure requires published, audited semi-annual and annual financial disclosures, giving you complete balance sheet visibility.
Shares are held in pooled nominee accounts under FCA CASS rules, supporting fractional shares and free in-specie transfers.
When you buy shares or index funds on CMC Invest, your legal title is registered under CMC Markets Investments Nominee Limited or an appointed institutional sub-custodian. Under this nominee model (holding securities in a dedicated trustee company rather than in your personal name), you remain the underlying beneficial owner with legal entitlement to all dividends and economic capital gains.
Your assets are segregated from CMC Invest's own operating cash in compliance with FCA Client Assets Sourcebook (CASS) requirements. If the broker faces insolvency, creditors cannot attach your assets to satisfy firm debts. You can also transfer whole shares out in-specie (moving portfolio holdings directly to another broker without selling to cash) completely free of platform processing fees.
Zero commission trades and no custody fees on the baseline plan, but a 0.99% FX margin adds up on overseas stocks.
If you invest $300 into an index fund each month, transaction commissions cost you $0 on CMC Invest's baseline Core plan. Across our standard ten-year investment projection of 121 recurring buys, trade commissions total zero and ongoing custody maintenance fees total zero. Unlike traditional UK wealth brokers charging percentage-based annual custody fees, CMC Invest keeps baseline portfolios free of ongoing account drag.
Access to over 4,600 UK and US equities and UCITS ETFs, though direct continental and Asian exchanges remain unavailable.
CMC Invest connects you directly to primary equity markets in the United Kingdom and the United States. On the baseline Core plan, the platform offers more than 4,600 assets, including more than 4,000 US shares, large-cap UK shares, over 400 ETFs, investment trusts, and REITs. Upgrading to the paid Plus or Premium plans broadens your investment universe to over 6,100 assets, adding 1,000+ mutual funds, mid and small-cap UK shares, and AIM shares.
Index fund investors will find hundreds of London-listed UCITS ETFs from major managers including Vanguard, iShares, and Invesco, enabling you to build globally diversified portfolios compliant with UK retail regulations. Fractional share dealing lets you invest in a portion of leading companies from just £1 within the Flexible Stocks & Shares ISA, SIPP, and GIA, so you can put small monthly amounts to work without needing the capital for a whole share price.
Intuitive mobile and web apps built for disciplined portfolio tracking rather than rapid algorithmic trading.
CMC Invest provides a streamlined investing experience across dedicated iOS and Android mobile apps alongside a browser-based web dashboard. Both platform channels maintain complete feature parity, allowing you to research assets, enter limit orders, fund your account, and track allocations without losing functionality when switching between your phone and laptop.
Direct market order routing without payment for order flow, offering market, limit, and stop orders plus extended-hours access to US shares.
When you submit trades on CMC Invest, your orders route to market execution venues under stringent UK regulatory rules. The Financial Conduct Authority strictly prohibits payment for order flow (PFOF, the practice of selling retail orders to wholesale market makers for kickbacks). Because CMC Invest receives zero PFOF revenue, your trades execute without conflicts of interest regarding order routing destinations.
The platform supports three core order choices: market orders, limit orders, and stop-loss orders. Setting limit orders allows you to define the maximum purchase price or minimum selling price you will accept, protecting your capital from unexpected volatility during market openings. Fractional shares can be bought through a market order by value, so you invest an amount from £1 rather than choosing a number of shares.
Flexible Stocks & Shares ISA, Cash ISA, Junior Cash ISA, and SIPP accounts alongside automated digital W-8BEN (US tax withholding certification) filing.
CMC Invest structures its accounts directly around the tax needs of UK retail investors. Alongside a standard taxable General Investment Account (GIA), you can open a Cash ISA and a Junior Cash ISA on the Core plan, a flexible Stocks & Shares ISA on the Plus plan (£6.99 monthly), and a Self-Invested Personal Pension (SIPP, a tax-advantaged retirement account) on the Premium plan (£10.99 monthly). The flexible ISA designation is a major advantage: it allows you to withdraw cash and replace it within the same UK tax year without reducing your annual £20,000 tax-free allowance.
Instant funding via UK Faster Payments and debit cards, with a £1 minimum per transaction and fee-free withdrawals.
Moving cash into CMC Invest is fast and free of platform transfer surcharges. You can fund your account using UK Faster Payments (FPS), instant Open Banking bank transfers, or UK personal debit cards. Bank transfers generally credit to your settled balance within minutes, allowing you to seize market opportunities without settlement bottlenecks.
Withdrawing your funds is just as clean. You can transfer settled cash back to your linked UK bank account free of administrative fees. Withdrawals are typically processed within 1 to 2 business days, and there are no minimum withdrawal thresholds holding back smaller amounts. General investment accounts and Cash ISAs both require a minimum deposit of £1 per transaction, though there's no minimum balance you need to maintain afterwards.
However, international banking rails are limited. Because CMC Invest UK serves domestic clients, you cannot deposit funds via overseas telegraphic wire transfers or foreign multi-currency fintech rails. On the free Core tier, international purchases trigger automatic conversion, as multi-currency holding wallets (USD and EUR) are reserved for paid plans.
Analyst ratings, price targets and ESG data powered by TipRanks and Morningstar, alongside practical learning guides and no gamification.
CMC Invest equips long-term investors with educational articles and foundational company metrics. Through the app's "Learn" library, you can read beginner-friendly guides explaining compound growth, index fund construction, ISA allowance rules, and financial statement terminology. Content concentrates on sustainable wealth building rather than high-risk trading habits.
Research tools are powered by TipRanks and Morningstar. You can see analyst ratings drawn from over 96,000 financial experts, 12-month price targets, bull and bear cases, and ESG preferences and ratings. Stock pages also provide valuation ratios, market capitalization, growth ratios, cash flow and income data, and company fundamental analysis is included on every plan.
Phone and email support with lines open from Sunday night to Friday night, whenever the markets are open.
CMC Invest provides customer assistance across three core channels: in-app messaging, email ticketing, and a dedicated UK telephone support line. Because customer service operates out of London, inquiries are handled by UK staff familiar with domestic ISA transfer procedures and British tax wrappers.
Community feedback across independent user review forums reports prompt query handling, with typical account questions resolved within 1 to 2 business days. CMC Markets' own complaints procedure says most queries are resolved immediately or within 24 hours, with a follow-up within five business days when further investigation is needed. Having direct telephone support available is a clear advantage over app-only competitors that route all customer inquiries through automated chatbots.
CMC Invest UK accepts individuals aged 18 and older who are legal tax residents of the United Kingdom with a valid National Insurance number and a UK personal bank account. The platform does not onboard US citizens, US residents, or persons domiciled outside the United Kingdom. Multi-currency holding wallets in US dollars and euros are available to clients who subscribe to the paid Plus or Premium plans.
CMC Invest is a secure, well-capitalized option for UK investors seeking a clean entry point into equity markets without ongoing custody holding costs. Backed by the substantial balance sheet of an LSE-listed parent firm, the stockbroking entity provides strong safety safeguards, full FSCS compensation coverage, and transparent monthly pricing tiers. While passive index investors focusing on UK shares and London-listed ETFs will find the zero-commission Core plan economical, international share buyers must weigh the 0.99% currency conversion fee or factor in the monthly cost of upgrading to paid tiers.
If you live in the UK and want to automate monthly investments into London-listed index funds or individual blue-chip equities, CMC Invest provides an accessible, custody-fee-free framework. It is particularly suitable if you want to bypass percentage-based platform fees charged by legacy institutions. However, if you plan to trade US shares frequently or require multi-currency accounts without monthly subscription charges, rival neobrokers offering lower currency exchange markups will be more economical over a ten-year horizon.
CMC Invest is owned by CMC Markets plc, a British financial services group founded in 1989 and listed on the London Stock Exchange under ticker CMCX. The investment service is operated through CMC Markets Investments Limited, a wholly owned subsidiary authorized and regulated by the Financial Conduct Authority under FRN 948126.
CMC Invest earns revenue through foreign exchange conversion markups, starting at 0.99% on the Core plan and decreasing on paid tiers. The company also generates income from optional monthly account subscriptions (£6.99 for Plus and £10.99 for Premium plans) and by earning interest margins on uninvested client cash balances.

The catch is that CMC Invest focuses strictly on the domestic UK retail investing audience. The parent group maintains separate leveraged CFD operations under distinct legal entities, but direct equity investing through this app remains cleanly insulated without cross-entity routing risk.
Bottom line: Top-tier UK regulatory licensing and full FSCS protection backed by an LSE-listed parent balance sheet make CMC Invest a structurally secure home for long-term investments.
“CMC Invest delivers institutional balance sheet clarity through its FTSE 250 parent firm while isolating share custody cleanly from CFD business lines.”
However, the nominee framework pools client holdings in collective accounts. Fractional shares are tracked through an internal ledger: while fractional allocations receive pro-rata cash dividends, you cannot transfer fractional positions out in-specie to an external platform. Additionally, CMC Invest does not explicitly name its overseas institutional US equity clearing partners in general retail disclosures.
Bottom line: CMC Invest relies on an established UK nominee system that safeguards your beneficial ownership and permits fee-free portfolio portability.
“Standard nominee pooling under FCA CASS regulations protects beneficial title, though fractional positions remain restricted to the platform.”
The key cost driver is currency conversion. When you purchase US stocks or non-sterling assets from British pounds, the Core tier applies a 0.99% foreign exchange markup. On each $300 international trade, that markup adds roughly $2.97. Across our ten-year recurring buy framework, foreign exchange costs accumulate to $455.40 on $46,000 of deployed capital.
CMC Invest also offers optional paid plans: the Plus plan at £6.99 monthly (adding Stocks & Shares ISAs and lowering the FX fee to 0.50%) and the Premium plan at £10.99 monthly (adding SIPPs and lowering the FX fee to 0.39%). While these tiers reduce variable currency friction on large orders, long-term buy-and-hold investors on the free Core plan must account for the 0.99% FX markup on overseas shares.

Across our standard ten-year projection of a $10,000 starting sum and $300 monthly deposits across 121 transactions ($46,000 invested), commissions total $0 and custodial account fees total $0 on the baseline Core plan. The sole expense is the 0.99% FX conversion fee on international assets. Converting the complete $46,000 capital volume generates a total ten-year cost of $455.40. Investors choosing the Plus plan (£6.99 monthly) or Premium plan (£10.99 monthly) pay fixed annual subscriptions of £83.88 or £131.88, which reduce the variable FX fee to 0.50% or 0.39%.
Bottom line: CMC Invest delivers exceptional value for UK-listed shares and ETFs, though international share purchases incur a 0.99% currency exchange markup on the free plan.
“Zero commissions and zero platform holding fees protect small sterling portfolios, but foreign exchange conversions on the Core tier carry a 0.99% markup.”
However, international coverage remains focused on North America and Britain. CMC Invest does not provide direct market access to European exchanges such as Euronext or Deutsche Börse Xetra, nor does it connect to Asian bourses. Furthermore, account opening is limited to UK tax residents, and the free Core plan does not include multi-currency cash balances, settling all international trades in British pounds.
Bottom line: CMC Invest meets core long-term equity and ETF allocation needs, but investors requiring direct European or Asian exchange routing must look elsewhere.
“Concentrating on US and UK listings gives passive index investors the essentials, though international exchange coverage remains limited.”
The interface is engineered around calm portfolio oversight. You receive clean asset allocation breakdowns, investment returns across custom timeframes, and historical dividend summaries. Order entry is straightforward and transparent, preventing execution errors. Watchlists and high-level sector filters help you organize prospective investments with minimal friction.
However, advanced chartists will notice the absence of complex technical analytical tools. The platform provides clean candlestick and line charts with basic time horizons, but lacks multi-indicator overlays or drawing suites found on professional trading terminals. There is no automated algorithmic script engine, no public retail trading API, and market pricing operates on a standard delayed basis until you stage an active order.
Bottom line: CMC Invest delivers clean, dependable software that makes long-term investing effortless while stripping away distracting trading noise.
“Complete parity between mobile and web channels makes portfolio monitoring straightforward, though technical charting remains basic.”
Because CMC Markets Investments Limited is a UK entity regulated by the FCA, US SEC Rule 605 and 606 venue disclosures do not apply. CMC Invest advertises extended-hours trading, letting you react to earnings reports and global news before the market opens or after it closes, and offers 24/5 trading on more than 4,000 US shares.
Bottom line: Transparent order routing complying with UK anti-PFOF standards, plus extended-hours access to US shares, makes CMC Invest dependable for regular long-term investing.
“Banning payment for order flow aligns execution with client interests, and extended-hours US trading adds flexibility for investors who want to react to news.”
For US stock investing, the platform streamlines withholding tax compliance. You sign a digital W-8BEN form directly inside the app during onboarding, reducing US dividend withholding tax from the standard 30% rate down to 15% under the US-UK double tax treaty. Cash dividends credit straight to your settled cash balance, and an automatic dividend reinvestment plan (DRIP) can be toggled on to reinvest payouts back into your holdings without manual effort.
Tax reporting is organized cleanly for taxable account holders. At the end of each UK tax year, CMC Invest produces an annual Consolidated Tax Certificate detailing capital gains, foreign dividends, and allowable costs. The main compromise is plan pricing: while several app-based rivals include Stocks & Shares ISAs for free, CMC Invest requires upgrading to its £6.99 monthly Plus tier.
Bottom line: Complete UK tax wrapper support and automated digital tax documentation make CMC Invest highly efficient for domestic wealth accumulation.
“Flexible ISA and SIPP integration provides top-tier tax efficiency, though equity ISAs require a paid monthly subscription.”
Bottom line: Domestic UK cash transfers are quick, free, and completely frictionless for British pound bank accounts.
“Open Banking integration makes domestic sterling cash transfers near-instantaneous, with zero platform exit fees.”
However, the research tools center on ratings, price targets and company data rather than deep valuation models. In-house commentary is provided through market news and analysis, but investors seeking advanced screeners or detailed valuation work will need external research tools.
Bottom line: CMC Invest offers a clean, distraction-free research interface with TipRanks and Morningstar powered tools on every plan, though experienced analysts may still want external valuation models.
“Objective educational guides and analyst data available on every plan support beginner investors, though deep valuation work still needs outside tools.”
However, phone support follows market hours. Lines are open from Sunday night to Friday night, whenever the markets are open, so there is no Saturday coverage. If a query is not resolved to your satisfaction, you can make a formal complaint to the Client Management team. If it remains unresolved after eight weeks, or you are unhappy with the final response, you can refer it to the UK Financial Ombudsman Service (FOS), which is free of charge, within six months of the final response.
Bottom line: Phone and email support covers market hours from Sunday night to Friday night, though there is no Saturday coverage.
“Maintaining a direct telephone support line elevates CMC Invest above app-only rivals that rely exclusively on chatbots.”
CMC Invest accepts fee-free deposits via UK Faster Payments, Open Banking instant transfers, or UK personal debit cards. General investment accounts and Cash ISAs require a minimum deposit of £1 per transaction, and funds sent through Open Banking typically credit to your settled cash balance within minutes.
CMC Invest accounts can be closed by liquidating your portfolio and withdrawing settled cash back to your linked UK bank account, or by transferring your share holdings in-specie to another broker. Once your balance reaches zero, contact support via in-app chat or email to finalize account closure without exit penalties.
CMC Invest pays variable interest on uninvested cash held in your General Investment Account. The Core plan pays 1.26% AER on GBP and USD, the Plus plan pays 2.27% on GBP and 2.53% on USD, and the Premium plan pays 3.30% on GBP and USD, with interest compounded once a month. Its Cash ISA is priced separately, with the investing page currently showing 3.69% AER (variable).
