Cost is where brokers in the same regulatory bracket actually differ.

Spreads from 1.0 pip suggest an all-in account, where the broker's fee is built into the price rather than charged separately. There is usually no commission on top, which makes the cost easier to predict.

Quoted spreads are best-case figures on the most liquid pair, in normal conditions. What you actually pay widens around news and at the session open.

Capital Index lists a minimum deposit of $0. Treat it as the cost of opening an account, not the cost of trading one - position sizing on a small balance is what tends to cause damage.

Leverage is capped at 1:30, which is the retail limit under tier-one regulation. It is a protection rather than a restriction: it caps how quickly a position can move against your balance.

Capital Index covers forex, indices, commodities, shares, fixed income. A wider range matters less than depth in the instruments you actually trade.

Funding options: debit/credit card, bank transfer. Check withdrawal routes as well as deposit ones - they are often not the same, and the difference only becomes apparent when you try to take money out.

Across a hundred brokers, the licence is what separates the field fastest.

Capital Index holds a tier-one authorisation from FCA. That matters more than any headline spread: it determines your leverage cap, whether losses can exceed your deposit, and what happens to your money if the firm fails.

The FCA caps retail leverage at 1:30, mandates negative balance protection, and covers eligible clients under the Financial Services Compensation Scheme.

Client money is held separately from the firm's own money, at Approved banking institutions; specific bank not publicly disclosed. That separation is what makes your balance recoverable if the company fails, rather than part of the pool its creditors divide up.

Negative balance protection applies, so a losing position cannot take the account below zero and leave you owing the broker money.

Covered by FSCS, up to £85,000 for eligible claims, which pays eligible clients up to its limit if the firm fails owing client money.

Check the licence yourself: the FCA Register.

Capital Index runs 4 account types. More choice is not automatically better: the tightest headline spread almost always sits on the account that also charges a commission, so the comparison that matters is the two added together.

Base currencies: GBP primarily, additional currencies depending on account. Holding the account in the currency you fund it with avoids a conversion charge on every deposit and withdrawal - a cost that never shows up in a spread comparison.

The smallest position is Instrument-dependent. For anyone starting carefully this matters more than the minimum deposit, because it sets the least you can put at risk on a single trade.

A demo account is available. Worth using for the platform rather than the results: fills are simulated, so it tells you how the software behaves but very little about execution.

Deposits and withdrawals

Deposit methods
Debit/credit card, bank transfer
Withdrawal methods
Bank transfer, cards where applicable
Deposit time
Cards generally immediate; bank transfer typically 1-3 business days
Withdrawal time
Typically several business days depending on method
Minimum withdrawal
Not currently published consistently
Local payment methods
UK bank transfer

Withdrawals are stated at Typically several business days depending on method, against Cards generally immediate; bank transfer typically 1-3 business days for deposits. A gap between the two is normal and not in itself a warning sign - identity checks are a legal obligation, not obstruction. What is worth noticing is a withdrawal that keeps meeting new conditions after those checks are done.

Withdrawal routes: bank transfer, cards where applicable. Money is usually returned by the route it arrived on, so the deposit method you pick is in effect the withdrawal method you are picking too.

The minimum withdrawal is Not currently published consistently - relevant if you intend to fund the account lightly, since it sets the smallest amount you can take out at a time.

Education

Research
Market analysis, weekly outlooks, technical/fundamental commentary, Signal Centre and MarketBOOK

Support runs 24/5 trading-week coverage. Round-the-clock cover matters more than it sounds: a position held over a weekend or through an unexpected halt is exactly when you need somebody to answer.

Reachable by live chat, email, telephone. A published telephone number is the one channel that is hard to fake and hard to ignore, so whether there is one says more than the number of channels does.

Languages: Primarily English. Being able to raise a complaint in your own language is worth more than it appears, because complaints are where precision matters most.

Education: extensive: trading education, webinars, platform guides, marketbook and educational content. Treat broker-published material as an introduction rather than as advice - it is produced by a firm whose revenue rises when you trade more.

Capital Index is roughly 12 years old. Younger is not worse, but there is less public record to judge it on, so the licence and the protections carry proportionally more weight.

The contracting entity is Capital Index (UK) Limited. This is the company you would actually have a relationship with, and it is worth checking that it is the same one named on the licence you are relying on: large brokers commonly operate several, and they are not equally protected.

Part of Capital Index Group. A parent adds resources, but the protections that apply to you are the ones attached to the entity that holds your account, not to the group.

Information is regularly updated. Last compiled from Capital Index's own website on 26 August 2026.
