IG vs CMC Markets: Which UK Broker Is Better In 2026?
IG and CMC Markets are two of the strongest traditional UK trading providers in the GradTraders broker bank. Both offer FCA-regulated routes, spread betting, CFDs, TradingView connectivity and mature proprietary platforms. The current comparison gives IG a narrow overall win at 8.8/10, while CMC Markets remains the stronger personal platform choice for traders who particularly value Next Generation.

Quick Verdict: IG Wins Overall, CMC Wins On Proprietary Platform Feel
IG wins this comparison by 8.8/10 to 8.7/10. The deciding factors are its broader modern platform ecosystem, greater account and product breadth, exceptional market coverage, investing routes and slightly stronger overall trust-and-scale profile.
CMC Markets remains the narrower winner for traders who prefer its Next Generation platform and active proprietary-platform experience. My own historical platform preference still leans towards CMC, but personal preference should not override the wider broker-bank evidence.
The difference is only 0.1 because both are excellent UK-facing brokers. This is not a strong broker versus a weak one. It is a comparison between IG’s wider all-round ecosystem and CMC’s more focused platform-led appeal.
Wins through platform breadth, market coverage, investing access, scale and the strongest complete UK all-round proposition.
Next Generation remains my preferred proprietary trading environment and CMC scores better for my historical practical experience.
Both provide established FCA-regulated UK spread-betting routes; platform and instrument costs should decide the choice.
Cost-sensitive scalpers should also compare Pepperstone, IC Markets and FP Markets before choosing either broker.

Platform Comparison: IG Ecosystem vs CMC Next Generation
This is the most important part of the comparison because both brokers are platform-led rather than bare-bones execution venues.
IG Platform Ecosystem
- IG proprietary web and mobile platforms.
- MetaTrader 4 and MetaTrader 5.
- TradingView connection for supported markets and routes.
- ProRealTime advanced charting and automation.
- L2 Dealer and direct-market-access tools for eligible users.
- Trading APIs and broader investing infrastructure.
IG wins the category because it supports more distinct professional and retail workflows.
CMC Next Generation
- Highly developed proprietary web and mobile environment.
- Strong charting, pattern tools and integrated research.
- Broad spread-betting and CFD instrument access.
- TradingView connectivity for supported CFD accounts.
- MT4 through a separate account and platform route.
- Positive first-hand GradTraders platform experience.
CMC wins when the decision is specifically about the quality and feel of the broker’s own trading platform.
Platform verdict: choose IG for overall platform choice. Choose CMC Markets when Next Generation itself is the reason you want the account. Traders committed to cTrader should compare other brokers because neither is the natural cTrader answer.
Spread Betting And UK Tax Position
Both IG and CMC Markets provide spread betting to eligible UK clients. This is a major reason they belong in the same comparison group rather than being judged only against global forex and CFD brokers.
Spread-betting gains are generally free from UK Capital Gains Tax and Stamp Duty under current rules, although tax treatment depends on personal circumstances and can change. CFDs remain available for traders who prefer that structure or require a particular product route.
Neither broker wins purely because it offers spread betting. The practical decision should come from the exact spread, overnight funding, platform, market, stop type and account experience.
Costs, Spreads, Margin And Leverage
CMC Markets receives the slightly higher category score, 8.2/10 versus IG’s 8.1/10, but the difference is too small to choose a broker without checking the instruments you actually trade.
Both brokers combine premium UK regulation and broad infrastructure with a spread-led pricing model on many products. Neither should automatically be assumed to beat raw-account specialists on frequent short-term trading costs.
An occasional spread bettor may reasonably prefer IG’s wider ecosystem or CMC’s platform without being concerned about a small difference. A high-frequency index trader should compare both against Pepperstone, IC Markets and FP Markets, then include entity, margin and withdrawal trade-offs rather than comparing headline spreads alone.
Regulation, Safety And Client Protection
Both brokers are serious UK-regulated names with public-company structures and decades of operating history. IG wins narrowly because its current UK structure, overall scale and 1974 founding date create one of the strongest trust profiles in the retail trading bank.
CMC Markets remains extremely strong. Its FCA-regulated UK route, client-money framework, public listing and history since 1989 make it a credible alternative rather than a compromise on legitimacy.
The exact accepting entity still matters. A familiar logo does not guarantee identical products, leverage or protections across every country and client classification.
Safety verdict: IG wins the institutional comparison, but both belong among the strongest UK trust profiles in the bank. Regulation does not remove the market risk of spread betting or CFDs.
My Experience With IG And CMC Markets
I have used both brokers. IG was an important earlier part of my trading journey, but my historical experience included occasions when I could not access my account during a live session and needed urgent support. That reduced my personal confidence even though the company itself remained well regulated and financially established.
I later moved to CMC Markets. Next Generation felt like a step forward for me, platform access was stable and execution was consistently good. I eventually left CMC as my index trading became more active and I wanted lower margin requirements, greater leverage and different cost conditions.
This experience explains why CMC wins execution and proprietary-platform preference in my comparison. It does not mean CMC must win the overall broker score. IG’s modern product and platform breadth now extends far beyond the narrower route I used historically.
The correct conclusion is therefore deliberately split: CMC Markets was the better personal trading experience; IG is the stronger complete modern all-round broker on the current evidence.

GradTraders Best Native Platform Choice: Plus500
Plus500
UK partner policy: GradTraders does not promote broker services to UK customers unless the relevant UK entity is authorised and regulated by the Financial Conduct Authority (FCA). Plus500UK Ltd (FRN 509909) is authorised and regulated by the FCA, and Plus500 is a firm we’re proud to partner with for our UK audience.
Plus500 is the GradTraders Best Native Platform Choice in this comparison. Its appeal is different from IG and CMC Markets: rather than competing on the widest third-party platform ecosystem, Plus500 centres the experience around its own user-friendly proprietary platform.
For eligible UK retail clients, client money is held in segregated bank accounts under FCA client-money rules, and retail CFD accounts include negative balance protection, which limits aggregate liability to the funds available in the trading account.
That combination makes Plus500 worth comparing for traders who value a native-platform experience and an FCA-authorised UK account route. It does not make CFDs low risk, and it does not replace the wider IG-versus-CMC verdict above.
Partner disclosure: Plus500 is a GradTraders affiliate partner. GradTraders may earn a commission if an eligible account is opened through this link, at no additional cost to you. This commercial relationship does not alter the IG 8.8/10 versus CMC Markets 8.7/10 editorial verdict.
Risk reminder: CFDs are leveraged products and can result in rapid losses. The provider-specific retail loss warning is displayed within the Plus500 banner above.
Prefer a native platform? Traders who do not need the broader IG or CMC Markets platform ecosystems can also compare Plus500, the GradTraders Best Native Platform Choice. For eligible UK retail clients, the Plus500UK route is authorised and regulated by the FCA and includes negative balance protection.
Alternative Brokers Worth Comparing
| Broker | GradTraders Position | Why Compare It? |
|---|---|---|
| Pepperstone | 9.1/10 · Best UK Active-Trader Route | FCA-regulated spread betting, cTrader and TradingView create a sharper active-trading alternative. |
| IC Markets | 9.2/10 · Active-Trader Benchmark | Raw pricing, cTrader, TradingView and international active conditions, with a different entity trade-off. |
| FP Markets | 9.0/10 · Flexible Active Route | Strong platform choice and competitive active-trader positioning without the same UK-specific appeal. |
| Plus500 | Best Native Platform Choice | User-friendly proprietary platform, FCA-regulated UK route for eligible clients and retail negative balance protection. A focused alternative to the broader IG and CMC Markets platform ecosystems. |
| Interactive Brokers | 8.9/10 · Serious Trader & Investor Route | Broader listed markets, futures, options and professional tools for users who do not need spread betting. |

Final Verdict: IG Wins 8.8 To 8.7
IG is the overall GradTraders winner because it provides the more complete modern UK broker ecosystem. Its advantage comes from regulation, platform range, market coverage, investing routes, scale and long operating history—not from being the cheapest broker on every instrument.
CMC Markets remains the platform-preference winner. Next Generation delivered the stronger personal trading experience for me, and CMC’s 8.9/10 execution and reliability score reflects that evidence.
The final answer therefore depends on the question being asked. For the best complete established UK all-rounder, choose IG. For the proprietary platform I would rather use for active spread betting and CFDs, choose CMC Markets.
GradTraders verdict: IG wins the full comparison by 0.1, while CMC Markets remains close enough that platform preference, actual instrument costs and personal workflow can reasonably reverse the decision for an individual trader.
