XTB Review 2026: Cash ISA & Stocks ISA Explained

XTB (X-Trade Brokers) is a publicly listed, FCA-regulated investment platform that launched in Poland in 2002 and now serves more than 2.5 million clients across 13 countries. In the UK, it is regulated by the Financial Conduct Authority (FCA) under registration number 522157 and is publicly listed on the Warsaw Stock Exchange — meaning its accounts are independently audited.

What makes XTB genuinely different from most UK platforms is its breadth in a single app. Where most savings and investment products are split across separate providers — a bank for your Cash ISA, a broker for your stocks and shares — XTB combines both under one login, with no platform fee for most users.

For the core UK use case — tax-efficient saving and investing with low fees — XTB is among the best options available in 2026. It won Best Low-Cost ISA 2025 (Boring Money) and has built a reputation for transparency, clean technology, and strong customer support across 18 languages.

What Is XTB — and Is It the Right Choice for You?

XTB (X-Trade Brokers) is a publicly listed, FCA-regulated investment platform that launched in Poland in 2002 and now serves more than 2.5 million clients across 13 countries. In the UK, it is regulated by the Financial Conduct Authority (FCA) under registration number 522157 and is publicly listed on the Warsaw Stock Exchange — meaning its accounts are independently audited.

What makes XTB genuinely different from most UK platforms is its breadth in a single app. Where most savings and investment products are split across separate providers — a bank for your Cash ISA, a broker for your stocks and shares — XTB combines both under one login, with no platform fee for most users.

The short answer to “Is it the right choice for you?” depends on what you need:

Everything You Can Do With One XTB Account

One login. One app. Cash savings, stocks, ETFs, and automated investing — all tax-free.

Most UK savers and investors hold accounts with at least two separate providers — a bank or building society for cash savings and a broker or platform for investments. XTB is built around the idea that this split is unnecessary and costly. With a single account, you get:

• A Flexible Cash ISA earning 4% AER — instant access, no lock-in, no minimum
• A Stocks & Shares ISA with zero commission on 9,000+ shares and 2,100+ ETFs
• Investment Plans — automated ETF portfolios from £15, with monthly auto-invest
• 4% AER on any uninvested GBP cash sitting in your account while you decide where to put it
• Access to stocks from the LSE, NYSE, NASDAQ, Euronext, and beyond
• Educational tools, market analysis, and a market calendar built into the app
• CFD trading on forex, commodities, and indices (for experienced traders only — see risk warning below)

XTB Cash ISA: 4% AER Flexible Cash Savings

The XTB Cash ISA is one of the most attractive cash savings products available in the UK market right now. It offers 4% AER (variable) on every pound you save, with no lock-in period, no minimum deposit, and no fees to open or maintain the account.

Key Features of the XTB Cash ISA

What Makes It Flexible?

A Flexible Cash ISA is different from a standard Cash ISA in one important way: if you withdraw money during the tax year, you can replace it later in the same tax year without it counting towards your £20,000 annual allowance again. This gives you much more control over your cash flow without sacrificing your tax-free savings capacity.

Example: You deposit £10,000 in April. In June, you need £2,000 for an unexpected expense and withdraw it. With a standard ISA, your remaining allowance for the year would be £10,000. With a Flexible ISA, you can replace the £2,000 later and still use the full £20,000 annual allowance by April.

Who Is the XTB Cash ISA Best For?

• Savers who want instant access and a competitive return without a fixed-rate lock-in
• Anyone who already invests with XTB and wants savings and investments in one app
• People making use of the full £20,000 ISA allowance who want flexibility to dip in and out
• Savers starting small — there is no minimum deposit requirement

XTB Stocks & Shares ISA: Tax-Free Investing with Zero Commission

The XTB Stocks & Shares ISA allows you to invest in a wide range of assets inside a tax-free wrapper. You pay no income tax on dividends and no Capital Gains Tax on investment growth, up to your £20,000 annual ISA allowance. XTB’s Stocks & Shares ISA is a Flexible ISA, meaning the same withdrawal-and-replace rules apply as with the Cash ISA above.

What Can You Invest In?

• 9,000+ real shares from the London Stock Exchange, NYSE, NASDAQ, Euronext, and other international exchanges
• 2,100+ ETFs from leading fund houses including iShares (BlackRock), Invesco, Vanguard, DWS Xtrackers, Lyxor, and VanEck
• Fractional shares: invest in expensive stocks (such as Amazon or Alphabet) from as little as £1
• Investment Plans: automated ETF portfolio investing with monthly auto-invest from £15

Key Features of the XTB Stocks & Shares ISA

Why the “One Platform” Advantage Matters

Most UK platforms force a choice: you either hold savings somewhere like a bank or building society and invest elsewhere through a broker. XTB collapses that distinction entirely. Inside a single XTB account, you can:

• Hold your emergency fund or short-term savings in the Cash ISA earning 4% AER
• Simultaneously hold a long-term investment portfolio in the Stocks & Shares ISA — same app, same login
• Earn 4% AER on any uninvested cash sitting in your Stocks & Shares ISA while you decide where to deploy it

This means you are never penalised for having cash sitting idle. Whether you are waiting for the right investment opportunity, building up a lump sum, or simply keeping a cash buffer, that money is still earning a competitive return inside the same tax-free wrapper.

XTB Investment Plans: Smarter Passive Investing

Investment Plans are XTB’s built-in tool for passive, long-term investing. They allow you to build a custom ETF portfolio, set up automated monthly contributions, and invest without having to pick individual stocks or time the market. Particularly well suited to beginners and long-term savers.

How Investment Plans Work

• Step 1: Choose your ETFs from a universe of 2,100+ funds. Filter by risk score, sector, region, or performance.
• Step 2: Allocate your desired percentage weighting to each ETF in your plan.
• Step 3: Set an initial deposit (£15 minimum) and optionally activate Auto Invest for regular monthly contributions.
• Step 4: XTB automatically invests your contributions into the ETFs in the proportions you have set.

Investment Plans can be opened inside a Stocks & Shares ISA, so all growth and income is sheltered from tax. You can open multiple plans simultaneously — for example, a retirement plan, a house deposit plan, and a child’s future fund.

Key Features

• Minimum investment: £15 per plan
• Commission: 0% on all ETF investments within the plan (up to £100k/month equivalent)
• Auto Invest: set-and-forget regular contributions by direct debit or card
• Transparency: full access to each ETF’s composition, risk score, and historical performance
• Flexibility: open and close plans at any time; quick deposits and withdrawals
• Low-cost ETFs: Total Expense Ratios (TERs) are rarely above 0.5% per year — far cheaper than actively managed funds

Stocks, ETFs, and More: What You Can Invest In

From UK blue chips to global ETFs — over 11,600 instruments across shares, funds, and markets.

Beyond ISAs and Investment Plans, XTB gives access to a broad range of asset classes. This makes it suitable for investors who want to go further than index-fund investing over time.

Stocks

• 6,800+ real shares from multiple stock exchanges including LSE, NYSE, NASDAQ, Euronext, and Xetra
• UK blue chips, US tech giants, European growth companies, and emerging market stocks all in one place
• Fractional shares from £1 — invest in expensive stocks like Tesla or Amazon with any amount
• Dividends passed through directly to your account

ETFs

• 2,100+ ETFs from providers including iShares, Invesco, Vanguard, DWS Xtrackers, Lyxor, and VanEck
• Global index trackers (e.g. FTSE All-World, S&P 500, MSCI World), sector ETFs, thematic ETFs, bond ETFs
• Zero commission up to £100,000/month; dividends credited automatically

Commodities, Forex & Indices (for experienced traders only)

• Gold, silver, oil, natural gas, agricultural commodities, 70+ currency pairs, and major global indices available as CFDs
• Maximum leverage of 1:30 in line with FCA restrictions for retail clients
• Negative balance protection applies to all CFD accounts
• Not available inside the ISA wrapper

XTB Fees: A Clear Breakdown

XTB has built its UK proposition around low costs. For the vast majority of savers and investors, the total annual cost of using XTB is close to zero — particularly for those investing regularly within ISA wrappers.

Earn Interest on Uninvested Cash

One of XTB’s standout features is that your uninvested cash earns interest regardless of which account type you hold — including cash sitting in a Stocks & Shares ISA while you decide where to invest it.

Current Interest Rates (from 20 July 2026)

Interest is calculated daily and credited monthly. Rates are variable and subject to change.

For most UK investment platforms, uninvested cash earns little to nothing. XTB’s 4% AER on GBP applies automatically to all accounts with no conditions, no minimum balance, and no requirement to hold an open trade.

Your Money Is Safe: Regulation, Protection & Security

FCA-authorised. FSCS-protected. Publicly listed and independently audited.

FSCS Protection: What’s Covered

XTB holds all Cash ISA client money in segregated Tier 1 Banks under CASS rules. Your cash savings are legally separate from XTB’s own operational funds and are FSCS-protected up to £120,000 in the unlikely event of XTB’s insolvency.

How to Open an XTB Account: Step by Step

Opening an XTB account takes approximately 10–15 minutes online. You will need a valid photo ID (passport or driving licence) and proof of address (utility bill or bank statement dated within the last 3 months).

Transferring an Existing ISA to XTB

• Open your ISA account in the XTB app
• Go to Manage → Transfer to XTB
• Enter your current provider’s details and the assets you wish to transfer

XTB supports transfers from both Cash ISAs and Stocks & Shares ISAs. Transfers may take up to 30 days. A transfer does not count as a new ISA subscription — your annual allowance is fully preserved.

Your capital is at risk. The value of your investments may go up or down. Tax treatment depends on your individual circumstances and ISA regulations which may change.

MoneyZoe Verdict: Is XTB Worth It?

XTB earns a rare five-star rating from MoneyZoe on the strength of a proposition that is genuinely difficult to beat in the UK market right now. The combination of a 4% AER flexible Cash ISA with a zero-commission Stocks & Shares ISA on a single, polished platform is exceptional value. There are no platform fees for the vast majority of users, no minimum deposit, and the experience — both in-app and from a regulatory standpoint — inspires confidence.

The platform is not perfect: the 4% Cash ISA rate is variable and could fall, the 0.5% currency conversion fee adds a small cost to international stock purchases, and XTB does not yet offer a SIPP or Junior ISA. But for the core use case — tax-efficient saving and investing for UK consumers — XTB delivers as well as any provider in 2026.

The “one platform” advantage is the real differentiator. Earning 4% on your cash while your investment portfolio also earns 4% on idle funds, both housed inside the same flexible ISA wrapper and the same clean app, is a level of integration that most competitors simply cannot match.

✓ Choose XTB if:

• You want a competitive Cash ISA and a zero-commission Stocks & Shares ISA — in one app
• You want to earn 4% AER on both your savings and your uninvested investment cash
• You value low or zero platform fees for most portfolio sizes
• You are a beginner or passive investor who wants automated ETF portfolios from £15
• You want fractional shares and access to 9,000+ stocks from a single account

✗ Look elsewhere if:

• You need a SIPP or pension account — XTB does not currently offer one
• You want a Junior ISA — not available on XTB
• You prefer managed funds (unit trusts / OEICs) — XTB focuses on stocks and ETFs

Your capital is at risk. The value of your investments may go up or down. Tax treatment depends on your individual circumstances and ISA regulations which may change.

XTB FAQs: People Also Ask

Is XTB regulated in the UK?

Yes. XTB Limited is authorised and regulated by the Financial Conduct Authority (FCA) under registration number 522157. It is also publicly listed on the Warsaw Stock Exchange, with independently audited accounts. Client money is held separately from XTB’s own funds under CASS rules.

Is XTB FSCS protected?

Yes. Eligible investments (stocks and ETFs) are protected up to £85,000 per person under the Financial Services Compensation Scheme (FSCS). Uninvested cash held in segregated Tier 1 Banks — including in the Cash ISA and Stocks & Shares ISA — is protected up to £120,000 per person. Always verify current limits at fscs.org.uk.

What is the 4% AER on XTB’s Cash ISA?

The XTB Cash ISA pays 4% AER (variable) on all balances. Interest is calculated daily and credited monthly within five days of the end of each month. There is no minimum balance and no lock-in period. The rate is variable, meaning XTB can change it without notice, so always check the current rate on the XTB website before opening an account.

Does XTB charge a platform fee?

For most users, XTB charges no platform or custody fee. There is no annual charge for portfolios below £250,000 equivalent (approximately 250,000 EUR). Above that threshold, a custody fee of 0.02% per annum (minimum £10) applies. Account opening, deposits, and withdrawals are all free.

Can I transfer my existing ISA to XTB?

Yes. XTB accepts ISA transfers from both Cash ISAs and Stocks & Shares ISAs held with other providers. The transfer process is handled in-app and typically takes up to 30 days. Transferring does not count as a new ISA subscription, so your annual £20,000 allowance is fully preserved.

Does XTB offer a SIPP or pension?

No. XTB does not currently offer a SIPP (Self-Invested Personal Pension) or any other type of pension account in the UK. If you need a pension alongside your ISA and savings, you will need to use a separate pension provider. This is the main gap in XTB’s product range compared to platforms like Hargreaves Lansdown or AJ Bell.

Does XTB offer a Junior ISA?

No. XTB does not currently offer a Junior ISA (JISA) in the UK. If you are looking to invest for a child in a tax-efficient wrapper, you will need to consider another provider such as Hargreaves Lansdown (which charges no fees on its Junior ISA) or Vanguard.

What is a Flexible ISA and why does it matter?

A Flexible ISA allows you to withdraw money from your account during the tax year and replace it later without that replacement counting towards your annual £20,000 ISA allowance. This is different from a standard ISA, where a withdrawal permanently reduces the allowance available for that tax year. Both the XTB Cash ISA and the XTB Stocks & Shares ISA are Flexible ISAs, giving you much greater cash-flow flexibility.

What is the currency conversion fee and when does it apply?

XTB charges a 0.5% currency conversion fee when you buy or sell assets denominated in a currency other than GBP. For example, if you buy shares listed on the NYSE (priced in USD), your GBP is converted to USD at the time of the trade, and the 0.5% fee applies to that conversion. For investors who hold primarily UK-listed assets, this fee is irrelevant. For those buying US or European stocks, it is a modest but ongoing cost to factor into your overall investment strategy.
