For most UK investors building a low-cost Stocks & Shares ISA, Trading 212 is the cheapest mainstream option in 2026.

We assess UK investment platforms on five criteria:
We give the most weight to total cost. Cost is the only variable you fully control as an investor — and over a 20-year horizon, the gap between 0.15% and 0.45% annual cost on a £20,000 ISA compounds to roughly £5,000 in fees forgone.
Trading 212 UK Ltd is a London-based investment platform authorised and regulated by the Financial Conduct Authority (FCA reference 609146). The parent group was founded in 2004; the UK arm has been FCA-authorised since 2013. The platform offers three account types — a general Invest account, a Stocks & Shares ISA, and a CFD account (the last is high-risk and unsuitable for most retail investors; we'll come back to this).
Client holdings are custodied via Interactive Brokers, one of the largest brokerages globally. Cash balances are FSCS-protected up to £85,000. The shares you hold are not on Trading 212's balance sheet — in the unlikely event of platform failure, your holdings would be transferred to a replacement broker, not at risk.
This is where Trading 212 wins. The fee structure is unusually simple for a UK platform:
For context, a Hargreaves Lansdown Stocks & Shares ISA charges 0.45% per year (capped at £45 for funds; no cap for shares) plus £11.95 per share trade plus 1% FX. On a £20,000 ISA held in shares, you'd pay around £90/year in platform fees alone before any trading. On Trading 212, the same ISA costs £0.
The honest catch: Trading 212 makes money elsewhere. They earn on the cash interest spread (they receive interest on uninvested funds and pay you slightly less), securities lending, and the small FX margin. This is the industry-standard "free brokerage" economic model. None of it costs the buy-and-hold ISA investor anything material.
A general account. Use this once you've maxed your ISA, or for separate purposes such as joint investing. Holdings are taxable: dividends count toward your dividend allowance (£500 in 2026), and gains count toward your CGT allowance (£3,000 in 2026).
The Stocks & Shares ISA. £20,000 annual allowance, all growth and dividends tax-free, can be transferred in from other ISA providers (Trading 212 doesn't charge for inbound transfers). This is the account most readers should open first.
Contracts for difference — leveraged derivative trading. Around 75% of retail CFD traders lose money. We don't recommend CFD trading for the vast majority of readers, and the fact that Trading 212 offers it is one of its weaker reputational features. If you're using Trading 212, stick to Invest or ISA.
Two features genuinely differentiate Trading 212 from most UK competitors.
Pies let you build a portfolio as a single visual unit. You set the percentage allocation of each holding — say 60% global tracker, 20% UK index, 20% bonds — and any deposit into the Pie auto-allocates to those percentages. It's similar to a managed portfolio, but you're in control of every component and pay nothing for the convenience.
AutoInvest layers recurring deposits on top. Set up a £200/month direct debit into a Pie and the platform invests on schedule, automatically rebalancing toward your target allocations. This is the closest UK retail equivalent to true "set and forget" investing.
Trading 212 supports fractional purchases from £1. This matters more than it sounds. A single share of Berkshire Hathaway A class costs roughly £540,000; one Amazon share is around £130. Fractional shares let you put £25 into Amazon, £25 into a global tracker, £25 into anything — regardless of share price. Most UK platforms still don't offer fractional shares cleanly.
Trading 212 pays interest on uninvested GBP, EUR and USD held in any account, including the ISA. The rate is variable and broadly tracks the Bank of England base rate. Interest earned inside the ISA is tax-free, which makes the Trading 212 ISA function as a hybrid cash-and-investment wrapper — unusual in the UK market. Most platforms either pay no cash interest or pay an uncompetitive rate.
The mobile app is rated 4.5+ on both iOS and Android. The web platform is functional but visually busier than Freetrade or Wealthify. Order placement is fast, the watchlist is rich, and Pie management feels native rather than bolted on. Customer service is chat-only — there's no phone line. Response time during UK business hours is usually under 10 minutes; complex queries take longer.
| Platform | Annual cost on £20k ISA | Standout strength |
|---|---|---|
| Trading 212 | £0 | Lowest cost; Pies; fractional shares |
| Freetrade Standard | £59.88 | Cleaner UX |
| InvestEngine | £0 (DIY only) | ETF specialist |
| Vanguard | £30 (0.15%) | Best if you only want Vanguard funds |
| Hargreaves Lansdown | £90+ | Widest product range; best phone support |
For pure cost, Trading 212 wins. For product breadth (SIPP, JISA, LISA, every UK fund), Hargreaves wins. For ETF specialists, InvestEngine is worth a look. For most beginner-to-intermediate UK investors focused on a Stocks & Shares ISA, Trading 212 is the answer.
Start-to-first-trade typically takes about 15 minutes if you have your ID to hand. Trading 212 has one of the smoothest onboarding flows in UK brokerage.
In 2026, Trading 212 is the cheapest mainstream UK Stocks & Shares ISA. The combination of zero fees, fractional shares, Pies, AutoInvest and competitive cash interest makes it the best entry point for first-time UK investors and a defensible choice for anyone whose investment goals fit within the ISA wrapper.
The gaps — no SIPP, no LISA, no JISA, chat-only support — are real, but matter less if you're focused on building a Stocks & Shares ISA. For most beginner-to-intermediate UK investors, Trading 212 is the most cost-effective platform you can use.
Trading 212 is FCA-regulated, free to open, and the ISA takes about 15 minutes from start to first share purchase.

Yes. Trading 212 UK Ltd is authorised and regulated by the Financial Conduct Authority (FCA reference 609146). Cash balances are protected by the Financial Services Compensation Scheme up to £85,000 per person per provider. Share holdings are custodied via Interactive Brokers and aren't on Trading 212's balance sheet, so in the unlikely event of failure your holdings would be transferred to a replacement broker.
Yes. Trading 212 accepts ISA transfers in from other UK providers with no transfer fee. The process is handled by your new provider — don't withdraw and redeposit, as that uses your annual allowance again. Transfers typically take 2–8 weeks depending on the source provider.
Not as of 2026. Trading 212 currently offers Invest accounts, Stocks & Shares ISAs, and CFDs. If you need a SIPP, AJ Bell, Vanguard or Hargreaves Lansdown are the major UK alternatives.
Withdrawals to UK bank accounts typically take 1–3 working days and there's no fee. Funds need to be uninvested first — you'll need to sell holdings and wait for settlement (T+2 for most shares) before withdrawing the resulting cash.
Cash balances are protected by FSCS up to £85,000. Share holdings are custodied through Interactive Brokers and remain your property — in the event of Trading 212 failure, holdings would be transferred to a replacement broker rather than at risk of loss.
No inactivity fee, no platform fee, no annual fee. The fees you'll actually pay are 0.15% FX on non-GBP share trades, and 0.7% on debit-card deposits above £2,000/year cumulative. Bank-transfer deposits are free.
