What is the Fidelity Stocks & Shares ISA?
A Stocks & Shares ISA is a tax wrapper that lets you hold investments without paying personal income tax on dividends or capital gains tax on profits (above the respective allowances). The Fidelity Stocks & Shares ISA is provided by Fidelity International, a UK investment platform regulated by the Financial Conduct Authority (FCA). Fidelity was founded in 1946 and has grown into one of the largest fund managers in the world, serving millions of customers across Europe, Asia and the Americas.
The Fidelity ISA lets you invest up to the annual ISA allowance (set at £20,000 for the 2025/26 and 2026/27 tax years). Within the wrapper you can hold a combination of funds (active and passive), investment trusts, ETFs, UK and international equities, bonds and cash. Fidelity is a “fund supermarket” — meaning you can build a portfolio from a very wide universe rather than being restricted to Fidelity’s own branded products.
Key features
Investment choice
Fidelity gives you access to over 3,000 funds from more than 150 fund managers, plus ETFs, investment trusts and direct shares. This is one of the largest selections on any UK platform. Notably, Fidelity’s own range of low-cost index funds (branded Fidelity Index) are among the cheapest passive funds on the market.
Ready-made portfolios
For investors who don’t want to pick their own funds, Fidelity offers managed portfolios. These include the Fidelity Pathfinder range of multi-asset funds and guided portfolio options that match your risk profile.
Regular investing
You can set up a regular investment plan from as little as £25 per month, which is ideal for pound-cost averaging. Dividend reinvestment is available at no extra cost.
Transfer in
Fidelity supports transfers of existing ISAs and SIPPs from other providers, and the team handles most of the paperwork.
Tools and research
The platform includes fund filtering, comparison tools, independent research ratings, and educational content. A free coaching session with a Fidelity retirement specialist is offered to new customers in some cases.
Mobile and web
Fidelity’s platform has historically been web-first, but its mobile app has improved significantly, letting you check balances, trade and manage regular investments on the go.

Pros and cons
Pros
- Huge investment universe with over 3,000 funds and access to ETFs, trusts and shares.
- Among the cheapest passive index funds available through Fidelity’s own range.
- Flat platform fee of 0.35%, capped for fund-only portfolios, which is competitive for medium-sized portfolios.
- Strong research and educational content.
- Free dividend reinvestment and low regular investment minimums.
- Long-established, FCA-regulated provider with a strong reputation.
Cons
- Share dealing fees (£7.50 per trade) are higher than some newer low-cost brokers.
- Platform fee not capped for share-heavy portfolios (the £7.50 cap applies only to fund holdings).
- No fractional shares for individual stocks (unlike some newer app-based platforms).
- The interface, while functional, is less slick than modern app-first rivals.
- Telephone advice is limited; full financial advice incurs additional cost.
Pricing
Fidelity’s pricing is transparent and competitive for fund investors. The platform fee is 0.35% per year on the value of your account, capped at £7.50 per month (£90 per year) for funds. This cap does not apply to share holdings, so investors who hold mostly individual shares will pay more in percentage terms.
For shares, online dealing costs £7.50 per trade, dropping to £1.50 for frequent traders (10+ trades in the previous month). Fund dealing is free. Fidelity’s own index funds have ongoing charge figures (OCFs) as low as around 0.06% for some funds, which makes building a low-cost passive portfolio very achievable.
External fund costs vary by manager, but Fidelity offers a discounted fund management fee (FMF) on many popular funds, typically 0.25% cheaper than retail.
| Cost type | Fidelity charge |
|---|---|
| Platform fee (funds) | 0.35%, capped £7.50/month |
| Platform fee (shares) | 0.35%, uncapped |
| Share dealing (online) | £7.50 (reduced for frequent traders) |
| Fund dealing | Free |
| Transfer out | Free |
| SIPP drawdown | Additional charges apply |
How it compares
| Platform | Platform fee | Fund universe | Share dealing | Best for |
|---|---|---|---|---|
| Fidelity | 0.35% (capped for funds) | 3,000+ | £7.50 | Fund investors, mid-to-large portfolios |
| Hargreaves Lansdown | 0.45% (tiered) | 3,000+ | £11.95 | Research-led investors |
| Vanguard | 0.15% (capped £375) | ~85 (Vanguard only) | N/A | Low-cost passive investors |
| Trading 212 | Free | ETFs + shares | Free | Frequent share traders |
| AJ Bell | 0.25% (capped) | 3,000+ | £5–£9.95 | All-round investors |
Fidelity sits in the middle of the market: cheaper than Hargreaves Lansdown, more expensive than Vanguard for very large portfolios (because Vanguard’s fee caps at £375), but with a far wider universe than Vanguard. Open a Fidelity ISA if the combination of fund choice and low fees suits you.
