IG vs CMC Markets: Which UK Broker Is Better In 2026?
IG vs CMC Markets: Which UK Broker Is Better In 2026?
IG and CMC Markets are two of the biggest names in UK trading. Both are established, both offer spread betting and CFDs, both are FCA-regulated in the UK, and both are natural comparison points for traders who want a serious UK broker rather than a small offshore CFD platform.
The short version is this: IG is the bigger traditional UK trading brand, while CMC Markets has the stronger trading-platform feel for active UK traders. My GradTraders verdict gives CMC Markets the narrow edge for active traders, while IG remains a major all-round choice for traders who value brand scale and market coverage.

Quick Verdict: CMC Markets Edges IG For Active UK Traders
CMC Markets is my narrow winner for active UK traders because its Next Generation platform, charting tools and trading-focused setup feel slightly sharper than IG for regular spread betting and CFD trading.
IG remains the stronger all-round UK trading brand if you want scale, familiarity, broad market access and one of the most established names in spread betting and CFDs.
This is not a comparison where one broker is clearly poor. Both are serious UK brokers. The difference is that IG wins on brand strength and scale, while CMC Markets feels more impressive as a trading platform for active users.

Where This Comparison Fits In The GradTraders Broker Bank
IG and CMC Markets sit in the traditional UK broker part of the GradTraders broker bank. They are different from IC Markets, Pepperstone or FP Markets because they are not mainly judged as raw-spread global CFD brokers. They are judged as UK-regulated trading platforms with spread betting, CFDs, broad market access and long-established reputations.
The wider GradTraders broker research covers platforms and tools, costs and spreads, execution and leverage, regulation and entity structure, funding and withdrawals, reputation and practical suitability, and market coverage. Across those layers, IG and CMC Markets both score well, but CMC Markets has the slight edge for active platform-led trading.
The public 24-broker table gives the wider context. This article narrows that research into a direct UK-broker head-to-head between two of the biggest names in the market.
What Is IG?
IG is one of the most established UK trading brokers, best known for spread betting, CFDs, market range and brand recognition. For many UK traders, IG is one of the first serious brokers they come across because it has been part of the UK trading landscape for so long.
IG’s strength is its scale. It offers a broad market range, a familiar trading platform, mobile app access and additional platform routes such as MT4, ProRealTime, L2 Dealer and TradingView depending on account and product setup.
The main caveat is that IG is not necessarily the sharpest low-cost active-trader broker. It can be excellent as a large all-round UK trading provider, but traders who become very spread-sensitive may eventually compare it with brokers such as CMC Markets, Pepperstone, IC Markets or FP Markets.
What Is CMC Markets?
CMC Markets is another major UK trading broker, best known for spread betting, CFDs and its Next Generation platform. In my view, CMC is one of the strongest UK proprietary trading platforms available to active traders.
The reason CMC Markets scores slightly above IG in this head-to-head is not because IG is weak. It is because CMC’s platform feels particularly well suited to active chart-based traders who want a serious UK spread-betting and CFD environment.
CMC is still a traditional UK broker, so traders looking for high-leverage offshore-style CFD trading may still look elsewhere. But within the UK-regulated broker group, CMC is one of the stronger active-trading options.
My View As A Trader
I have used both IG and CMC Markets in the past. My own trading journey eventually moved towards lower-spread active CFD routes, but that does not mean either IG or CMC is weak. They are both serious brokers and both deserve respect.
If I was choosing between IG and CMC Markets purely as a UK spread-betting and CFD trader, I would lean towards CMC Markets because I prefer the trading-platform feel. If I wanted the biggest all-round traditional UK trading brand, IG would still be very hard to ignore.
The important point is that this comparison is not about legitimacy. Both are serious names. It is about which one better suits the trader’s style.
Platform Comparison: IG Ecosystem vs CMC Next Generation
IG Platform Strengths
- Large and familiar IG trading platform.
- Mobile app and web trading access.
- MT4 route for MetaTrader traders.
- ProRealTime and L2 Dealer routes for more specialist users.
- TradingView relevance for chart-led traders.
- Broad market coverage across spread betting and CFDs.
CMC Markets Platform Strengths
- Excellent Next Generation platform.
- Strong charting and trading tools.
- Good mobile and web trading experience.
- MT4 availability for supported markets.
- TradingView connectivity improves the charting workflow.
- Strong fit for active UK spread bettors and CFD traders.
IG wins on the breadth of its overall platform ecosystem. CMC Markets wins on proprietary platform feel. For the way many active UK traders compare trading platforms, that gives CMC the slight edge.
Costs, Spreads And Trading Conditions
Neither IG nor CMC Markets should automatically be assumed to be the cheapest broker for active traders. Both are major UK brokers with serious platforms, but traders still need to compare spreads, overnight funding, commissions, margin requirements and account-specific costs.
IG can be competitive and offers broad market access, but it is not usually the first broker I think of when the priority is the sharpest possible active-trader cost structure.
CMC Markets also needs instrument-by-instrument checking, but its trading-platform strength and active-pricing features make it slightly more attractive to me for active UK trading. As always, the correct comparison is based on the markets you actually trade, not one headline spread.
Which Broker Is Better For UK Traders?
Both IG and CMC Markets are strong for UK traders because both understand the UK spread-betting and CFD market. Both have FCA-regulated UK routes and both are familiar names for traders who want a regulated UK broker rather than an offshore CFD account.
IG is probably the easier first choice for traders who simply want the biggest recognised UK trading brand. CMC Markets is the better fit for traders who care more about platform experience and active trading workflow.
For a complete beginner who wants the biggest name, IG may feel safer and more familiar. For a more active trader who wants a stronger trading platform, I would look more closely at CMC Markets.
Which Broker Is Better For Active Traders?
CMC Markets gets my edge for active UK traders. The Next Generation platform, charting tools and overall trading feel make CMC a strong choice for traders who are actively watching markets rather than just placing the occasional trade.
IG is still strong. Its platform ecosystem is broad and its brand is enormous. But as a direct active-trader comparison, CMC Markets feels slightly sharper.
That is why my score puts CMC Markets above IG, even though IG remains one of the most important brokers in the UK market.
Regulation And Safety
Both IG and CMC Markets are serious regulated UK broker names. For UK traders, FCA regulation matters because it affects leverage limits, client protection, marketing rules, complaint routes and how retail clients are treated.
That does not make spread betting or CFD trading safe. It simply means the broker is operating within a recognised regulatory framework. Traders can still lose money quickly, especially when using leverage without proper risk control.
The right question is not simply “which broker is safe?” It is “which broker, product, account type and risk level actually suits the way I trade?”
