City Index Review UK 2026 (FCA Regulated)

City Index scores 78/100 in our testing. This review is based on a live UK account, opened at the broker's FCA-authorised entity, funded in GBP and traded. The EUR/USD, GBP/USD and EUR/GBP spread figures shown are modal values recorded on that account across three trading days in July 2026.

City Index suits traders who want an established UK name with broad market access. Deep UK heritage since 1983, a StoneX parent and a dual CFD and spread-bet offer across Web Trader, MT4 and TradingView are the reasons to choose it, and it trades as a brand of StoneX Financial Ltd, FCA-authorised under FRN 446717. Cost-led scalpers who chase the tightest raw spread should look elsewhere.

What I value about City Index is its UK heritage, market breadth, and platform choice. It has operated since 1983 and sits within the NASDAQ-listed StoneX group. You get forex, indices, shares and commodity CFDs in one account, plus a spread-bet account for UK clients. Platform choice covers Web Trader, MT4 and TradingView, covering most workflows without locking you into one tool.

I would not send cost-led scalpers here. With no raw-spread commission account, the cost is all in the spread, and our July 2026 recording put EUR/USD at a modal 1.4 pips. That is the widest in the FCA-regulated set we review, level with Trading 212. If you need MT5 or cTrader, you will not find them on the UK offer.

City Index suits traders who value an established UK name, a dual CFD and spread-bet offer, and TradingView charting. For cost-led scalpers or anyone who needs MetaTrader 5 or cTrader, I would point you elsewhere in the set.

City Index quick facts

City Index trades as a brand of StoneX Financial Ltd, and the table below collects the figures a UK trader checks first. I would start there.

Trading costs and fees

City Index prices through the spread on its core offer, with no raw or commission account at all, and our own recording shows the cost runs well above the advertised starting rate. The protocol behind these numbers, and the tier this review sits in, is covered in how we test. The draw here is heritage and breadth rather than a tight spread.

CFD account costs

The broker quotes EUR/USD from 0.7 pips and GBP/USD from 1.1 (broker site, accessed 10 July 2026). On a live UK account in July 2026 EUR/USD tested at a modal 1.4 pips, GBP/USD at 1.8 and EUR/GBP at 2.0, roughly double the from-rate in each case. That puts one standard lot of EUR/USD near £10.30, all of it spread, and makes City Index the widest tested EUR/USD in the FCA-regulated set we review, level with Trading 212.

I think the gap between the 0.7 advertised and the 1.4 we recorded is the single most useful number on this page. A from-rate is a best case; the modal is what you actually pay most often.

Spread betting costs

If you are a UK client, you can open a spread-bet account alongside the CFD account. It is priced the same way on major markets, not on its own schedule. HMRC does not normally treat placing a spread bet as trading, so those profits are not taxed and losses attract no relief, and no stamp duty applies. Tax treatment depends on your individual circumstances and can change.

Other fees UK traders should check

Funding is free in both directions, so the spread is effectively your whole cost. At 1.4 pips tested, that is a lot of cost to carry. I would flag two practical floors: card deposits have a £100 per-transaction minimum, and withdrawals have a £100 minimum or your full balance if lower. Overnight funding applies to positions held open, on top of a spread that is already the widest here.

Trading platforms

City Index offers Web Trader, MT4 and TradingView, plus a spread-bet account alongside CFDs. There is no MT5 or cTrader in our latest check of the UK entity.

Web Trader

Web Trader is City Index’s own platform and carries the SMART Signals pattern-recognition tools and the in-platform research. In my view, it is competent rather than a reason in itself to choose the broker.

MetaTrader 4

MT4 runs alongside Web Trader for traders bringing an expert advisor. There is no MT5, so the newer generation is unavailable. I would point you to The MT4 field in the UK for a separate comparison.

TradingView

If you are a chart-led trader, TradingView is the platform pick, and it connects to a City Index account. It is the most modern part of the offer. Which UK brokers run TradingView is covered separately.

Mobile apps

I find City Index’s mobile apps carry Web Trader’s core in a lighter form for account management and order entry.

Trust and safety

City Index trades as a brand of StoneX Financial Ltd, with UK heritage dating to 1983. I see that heritage as the main reason the brand stands out.

FCA regulation

StoneX Financial Ltd, trading as City Index, is authorised and regulated by the FCA under FRN 446717 (FCA register record, checked 16 July 2026), part of the NASDAQ-listed StoneX group, with UK heritage dating to 1983. One point to note: Forex.com is a trading name of the same firm, so City Index and Forex.com now share an authorisation rather than merely a parent. The Forex.com UK business previously ran through Gain Capital UK Limited (FRN 113942), which is no longer its counterparty. FSCS cover is per firm, so money held with both brands is covered once up to £85,000, not twice. On execution model, City Index executes as a market maker against its own book with StoneX group liquidity behind it, publishing order-execution and best-execution policy documents rather than a headline fill-speed figure; requotes are not a feature of its standard CFD execution.

Client money, FSCS and negative balance protection

I would note that City Index is a brand rather than a company: your counterparty is StoneX Financial Ltd, whose NASDAQ-listed parent publishes audited accounts. Client money is held in segregated accounts under the FCA’s CASS rules, separate from the firm’s own funds. Negative balance protection applies to retail accounts, so a position cannot leave you owing more than your balance. If the firm failed, FSCS cover runs up to £85,000 per eligible person, covering shortfalls in client money and assets rather than trading losses. Disputes escalate to the Financial Ombudsman Service, and how FCA authorisation protects you covers the award limits.

History and ownership

City Index has operated in the UK market since 1983, which is second only to IG in this set, and it sits inside the NASDAQ-listed StoneX group. The listed parent publishes audited accounts. I see that heritage and balance sheet, rather than pricing, as what draws traders to the brand.

Public reviews

Trustpilot rates City Index 4.4 out of 5 from 390 reviews (Trustpilot profile, captured August 2026). That is near the top of the FCA-regulated brokers we cover, where the range runs from 2.0 to 4.6, though on a much smaller review count than the largest brands here carry, so read it with that in mind. It also sits strikingly against the widest tested spread in our set, which suggests reviewers are rating service and heritage rather than cost. Read it as a brand-level signal rather than a UK verdict, since Trustpilot profiles cover the whole brand across every market. Scores also move, so treat the figure as a August 2026 snapshot.

TradingView users rate City Index 3.8 out of 5 from 238 ratings (TradingView profile, captured August 2026), on 3K connected accounts. That is a small sample by the standards of this page, where the largest runs past 38,000, so treat it as indicative rather than settled.

Account types and minimum deposit

A CFD account and a spread-bet account cover the UK offer.

Account options for UK clients

Both accounts price alike on major markets and differ on tax treatment rather than model. There is no raw or commission tier. Tax treatment depends on your individual circumstances and can change.

Minimum deposit

City Index has no minimum deposit to open either account (broker site, accessed 10 July 2026). The practical floor is a £100 per-transaction minimum on card deposits, while bank transfers carry no minimum.

Funding and withdrawals

Funding is free in both directions, with £100 floors on cards and withdrawals.

Deposit methods (UK clients)

Deposits by debit card, credit card or bank transfer are free, and PayPal deposits are no longer accepted (broker site, accessed 10 July 2026). Card deposits carry a £100 per-transaction minimum; bank transfers carry none.

Withdrawals

Withdrawals are free of charge, with a £100 minimum withdrawal or your full balance if lower.

• Card withdrawals: three to five working days
• UK bank transfers: one to two working days, or one working day where the bank uses Faster Payments

Account opening

Opening is online, with identity and address verification under the FCA’s client-onboarding rules. There is no minimum deposit, so you can start without funding up front, though the £100 card floor applies when you do.

Product range

City Index covers forex, indices, shares and commodity CFDs across a broad range, with a spread-bet account alongside for UK clients. For depth on any single asset class, start at the CFD broker comparison.

Any crypto product City Index markets elsewhere is unavailable to UK retail. The FCA banned the sale of crypto derivatives to UK retail consumers from 6 January 2021. The markets table above states that in the crypto row, and no crypto tier appears in the leverage list because the FCA caps do not include one.

Index CFDs

City Index quotes the main global benchmarks at 20:1 retail leverage on the majors. I would point you to our index CFD brokers page for a comparison across the set, and to the share CFD brokers page for equities.

Spread betting markets

The spread-bet account covers the same market list as the CFD account, so you choose between them for tax treatment, not breadth.

Leverage for UK traders

Retail leverage at City Index follows the FCA’s standardised caps rather than anything the broker sets, and applies equally to the CFD and spread-bet accounts. No FCA broker exceeds these caps; what the caps allow explains the margin that follows from them.

Customer service

City Index runs UK support by live chat, phone and email, with account and platform help centred on its online help pages.

As a StoneX brand the help centre shares structure with Forex.com but is staffed for City Index products, including spread-betting queries. We describe support here from published information rather than timed response tests on the UK desk.

Research and education

In my experience, City Index’s in-platform analysis is a useful extra. It includes daily market commentary, a news feed and an economic calendar inside Web Trader. A structured trading academy covers CFD and spread-betting basics, and SMART Signals pattern-recognition tools flag chart setups where available. If you want deeper third-party charting, the TradingView integration is there. We describe the offer from City Index’s published material pending a live assessment.

How City Index compares to alternatives

Pepperstone runs the raw commission account City Index lacks, which is the entire cost argument. Forex.com is the same UK firm, trading under a second name on the same FCA authorisation (StoneX Financial Ltd, FRN 446717), so weigh the two on platform and interface rather than as a way to spread counterparty risk. For breadth on a deeper platform, CMC Markets is the closer match. The reviews index ranks the wider UK field, and every FCA broker we rate sits in one place.

Should you open an account with City Index?

Yes. City Index suits traders who value UK heritage back to 1983, a listed StoneX parent, and a CFD account with a spread-bet account beside it. I recommend it for exactly those traders. City Index trades as a brand of StoneX Financial Ltd under FCA authorisation FRN 446717, with no account minimum, free funding both ways and TradingView alongside Web Trader and MT4.

No. I would not send raw-spread cost hunters here. There is no commission-based raw account, so the all-in price never matches the ECN-style leaders, and our July 2026 recording put EUR/USD at a modal 1.4 pips: the widest in the FCA-regulated set we review, level with Trading 212, and roughly double the advertised from-rate. Traders who need MT5 or cTrader will not find them here either.
