CMC Markets vs Pepperstone: Which broker is best for UK traders in 2026?

This comparison cuts through the noise. It covers spreads, platforms, instruments, regulation, spread betting, fees and Financial Services Compensation Scheme (FSCS) protection – with sources clearly stated so you can verify every figure yourself. Neither broker is necessarily the right choice for everyone.

Quick verdict: CMC Markets vs Pepperstone at a glance

Choosing between these two brokers comes down to two things: what you trade and how you trade it.

CMC Markets is the stronger pick for UK spread betters and discretionary traders who want the widest instrument range and the most capable in-house platform. Pepperstone leads on raw trading costs and platform flexibility – especially for algo traders, scalpers, and copy traders who need MT4, MT5 or cTrader.

Both are regulated by the Financial Conduct Authority (FCA), and offer FSCS protection up to £85,000.

Fees & spreads compared: Which is the cheaper broker?

Spread costs are where traders can lose money without realising it. A difference of 0.3 pips on EUR/USD may look small, but across hundreds of trades a year it becomes material.

CMC Markets operates a commission-free standard account. It builds its costs into the spread. Its average EUR/USD spread is 0.70 pips (fxscouts.com, April 2026).

Pepperstone offers two pricing models. Its Standard account charges no commission and averages 1.00 pip on EUR/USD. Its Razor account charges raw spreads averaging 0.10 pips on EUR/USD, plus a commission of $3.50 per lot per side on MT4 and MT5 — $7 round-trip per standard lot. The all-in cost on the Razor account works out at around 0.80 pips on EUR/USD, which is slightly more expensive than CMC’s commission-free spread of 0.70 pips for lower-volume traders (ForexBrokers.com, March 2026).

For high-frequency traders executing dozens of standard lots daily, Razor’s near-zero raw spread can reduce total cost below CMC’s. For most retail traders trading smaller volumes, CMC’s 0.70 pip all-in cost is the more straightforward and cheaper option.

Share CFD commissions apply at both brokers, although CMC Markets doesn’t charge commission on UK and European share CFDs (except Greece shares). Pepperstone charges between 0.07% and 0.20% per side depending on the market traded (pepperstone.com, 2025/26). The commission on US shares is the same at both brokers, at 2 cents per share. Pepperstone’s lower floor on some countries gives a slight edge for large share CFD positions, although CMC Markets, with zero commission, will clearly be more cost-effective on UK and European shares (exc. Greece shares.

Tradable instruments: How many markets does each broker offer?

If instrument range matters to you, CMC Markets wins by a clear margin.

CMC Markets offers more than 13,000 instruments across forex, indices, shares, ETFs, commodities, and treasuries, and for professional clients only, cryptocurrencies. Its forex range alone comprises 300+ currency pairs – more than any other FCA-regulated spread betting broker.

Pepperstone offers approximately 1,726 instruments, including 90+ forex pairs, 25 global indices, 900+ share CFDs, 17 commodities and 100+ ETFs (fxscouts.com, April 2026). The range is solid for most active traders but falls well short of CMC’s breadth for those who need niche markets.

Regulation & safety — FCA, ASIC and UK client protections

Regulation is the starting point, not the finish line. Both brokers are FCA-regulated, which means they are legally required to hold client funds in segregated accounts, offer negative balance protection to retail clients, and meet ongoing capital adequacy requirements.

Regulation confirms your broker meets the FCA’s minimum standards. It does not eliminate trading risk. If a trade goes against you, the FSCS does not compensate your loss. See section 11 for a full explanation of what FSCS does and does not cover.

Trading platforms: CMC platform vs Pepperstone MT4/MT5, mobile trading app

This is where the two brokers differ most. Your platform choice directly affects your ability to execute your trading strategy, so it is worth spending time here.

CMC Markets ‘Next Generation’ platform is a proprietary web and mobile platform with 115+ technical indicators, pattern recognition, advanced charting and an integrated client sentiment tool. It is built for discretionary traders who want data and analysis in one place. CMC now also supports MT4, MT5 (selected regions) and TradingView, giving algo traders an option. The Next Generation mobile app closely mirrors the full web platform and won Best Mobile Trading Platform at the ADVFN International Financial Awards 2025.

Pepperstone’s platform range is broader for active traders. It supports MT4, MT5, cTrader, TradingView and its own Pepperstone WebTrader. For traders running Expert Advisors, MT4 integration is native and well-optimised. cTrader adds copy trading and is favoured by ECN-style traders who want direct market access pricing.

For scalpers and algo traders who need MT4 or cTrader natively with raw spreads, Pepperstone may be the better fit. For discretionary traders who want a polished single platform with research tools built in, CMC’s proprietary platform and native app leads.

Account types & minimum deposit requirements

Neither broker requires a minimum deposit to open a live account. Both recommend depositing enough to cover margin requirements on your first trades.

Spread betting: Why CMC Markets leads for UK traders

Spread betting is the most tax-efficient way to trade financial markets in the UK. Profits are exempt from capital gains tax and stamp duty under UK law, because spread bets are classified as gambling. This can potentially make it a powerful tool for active traders.

Tax note: Tax treatment depends on individual circumstances and UK tax law can change. The information above is not tax advice. Seek independent tax advice before using spread betting as part of a tax planning strategy.

CMC Markets offers its full 13,000+ instrument range via its spread betting account, including 300+ forex pairs that no rival UK spread betting provider matches. According to CMC Markets, over 2 million unique logins were recorded across its platforms in November 2025 – a sign of the depth of its UK client base (CMC Markets, November 2025).

Pepperstone also offers spread betting to UK clients through its FCA-regulated entity, Pepperstone Limited (FRN 684312). The instrument range is smaller, but spreads are competitive and execution is fast. For traders who already use MT4 or cTrader and want a tax-efficient overlay without switching platforms, Pepperstone’s spread betting account is a practical option.

The key risk with spread betting is overnight financing. Each day you hold a leveraged spread bet, a financing charge applies. On large index positions held for several weeks, this charge can compound significantly and reduce or eliminate any tax saving. Always calculate the true all-in cost of holding before entering a position.

Research, education & market analysis tools

CMC Markets has one of the most comprehensive research suites available from an FCA-regulated broker. Its Next Generation platform includes Reuters newsfeeds, an economic calendar, pattern recognition alerts, analyst commentary and a client sentiment indicator that shows live positioning data from other traders.

CMC won Best Spread Betting & CFD Education Tools at the ADVFN International Financial Awards 2025 — a recognition of the depth of its educational content across articles, videos and in-platform guides.

Pepperstone’s research offering is solid but more limited. It provides access to newsfeeds, a market calendar and a library of webinars and platform tutorials on its YouTube channel. The Pepperstone Academy covers trading basics through to advanced technical analysis and is well-structured for beginners. Webinar frequency appears to have reduced in the second half of 2025.

For traders who rely on analysis and education as part of their process, CMC Markets is the stronger option. For traders who bring their own analysis and simply need a fast execution environment, Pepperstone’s research offering is sufficient.

Customer support: Responsiveness & quality

Both brokers offer 24/5 support during trading days — covering Sunday evening through Friday night, in line with global market hours.

CMC Markets provides phone, email and live chat support. Its support team is available throughout market hours.

Pepperstone operates a local UK helpdesk, supported by global colleagues to maintain consistent coverage. Phone, email and live chat are all available.

Neither broker provides 24/7 support. Urgent queries raised over the weekend are typically handled by email until markets reopen. If weekend support is a hard requirement, this is worth factoring into your decision.

Inactivity warning: CMC Markets charges £10 per month on accounts dormant for 12 months or more. If you trade infrequently or hold an account open between strategies, this cost will apply. Pepperstone does not charge an inactivity fee, though dormant accounts may be archived after three months.

FSCS coverage & FCA protections: What UK traders must know

The Financial Services Compensation Scheme (FSCS) protects eligible UK clients of FCA-regulated firms up to £85,000 per person, per firm.

Both brokers hold client funds in segregated bank accounts under FCA Client Money rules. Your funds sit apart from the broker’s own capital. Even outside the FSCS, this ring-fencing gives your money a layer of protection in an insolvency event.

Which broker should I choose?

Here is a plain-English verdict by trading profile. Match yourself to the description that fits and follow the recommendation.

Choose CMC Markets if you:

1. Are a UK spread better who wants the widest instrument range and no need to switch platforms

2. Trade indices, commodities, niche forex pairs, share baskets, forex indices, or commodity indices that Pepperstone does not offer

3. Value in-platform research tools, pattern recognition and integrated newsfeeds

4. Prefer a single platform for spread betting and CFDs, supported by a publicly listed UK firm with over 35 years’ experience

5. Are a trader who holds multi-asset positions for days to weeks

Choose Pepperstone if you:

1. Run Expert Advisors on MT4 or MT5 and need native algo support with raw ECN-style spreads

2. Are a scalper or day trader where the Razor account’s near-zero raw spreads reduce your cost per trade

3. Want to copy trade experienced traders via cTrader while you build your own strategy

4. Do not trade often enough to be affected by the £10/month CMC inactivity fee (applicable after 12 months’ inactivity only if there are funds in the account), and value Pepperstone’s zero inactivity charge

Both brokers are FCA-regulated with FSCS protection up to £85,000. The choice is about fit, not safety. Regulatory protection is equivalent. Execution quality, spread costs and platform capability are where these brokers genuinely differ.
