Low-Cost UK Stocks & Shares ISA

Low-Cost UK Stocks & Shares ISA

A Stocks & Shares ISA from SCM Direct costs 0.85% per year, all-in. This single figure covers discretionary management, ETF charges, custody, trading and transaction costs — there are no initial charges, no exit penalties and no performance fees. The minimum to open an ISA is £10,000; the 2026/2027 ISA allowance is £20,000.

SCM Direct is regulated by the Financial Conduct Authority (Firm Reference Number 497525) and was founded in 2009 by Alan and Gina Miller, who co-invest their own and their family’s money in the portfolio on the same terms as clients.

If you are deciding where to open a Stocks & Shares ISA and want an ETF portfolio with a single, transparent fee, expert management, this page explains what “low-cost” actually means in 2026, where hidden costs live, and how SCM Direct compares to well-known brands and platforms.

What “low-cost” actually means for a UK Stocks & Shares ISA

The headline platform or management fee is rarely the total cost. For most UK Stocks & Shares ISAs, you pay some combination of:

  • Platform or service fee — often 0.15%–0.45% per year, sometimes capped
  • Fund Ongoing Charges Figure (OCF) — 0.10%–0.95% per year, depending on the funds you hold
  • Dealing or transaction costs — typically £1.50–£12.50 per trade, sometimes free
  • Foreign-exchange fees on overseas holdings — frequently 0.25%–1.5%
  • Exit or transfer-out fees — £25 per holding is common when you leave
  • Performance fees — rare in retail ISAs but still present in some discretionary services

The total “all-in” cost — the number that actually matters — is the sum of all of these that you will pay for a year. It is what the Financial Conduct Authority refers to as Total Cost of Ownership.

At SCM Direct, the 0.85% headline figure includes every line in that list. There is no separate platform fee, no fund OCF on top, no per-trade dealing cost, and no exit penalty. One number, all-in.

DIY ISA vs discretionary ISA — the distinction most buyers miss

When you compare UK ISA providers, the first decision is not which platform — it is which type of service.

A DIY ISA platform is a fund supermarket. You decide what to buy (which funds, which ETFs, which shares), when to buy and sell, when to rebalance, and how to allocate across risk levels. Vanguard Investor, AJ Bell Youinvest, Hargreaves Lansdown, Fidelity Personal Investing and Interactive Investor are DIY platforms. They are excellent for investors who are confident enough to choose and manage their own portfolio.

A discretionary ISA is a managed portfolio. A regulated investment manager makes the investment decisions on your behalf — what to hold, how to allocate, when to rebalance — within the risk profile you choose. You retain full ownership; the manager has authority (discretion) to invest under a contractual mandate.

SCM Direct is a discretionary option. Alan Miller and the SCM team make the investment decisions; you choose the risk profile (Cautious, Balanced, Adventurous, Equity, Ethical/ESG, Long-Term Return, Absolute Return, Bond Reserve) and the firm manages it from there.

This is a meaningful product difference, not just a pricing one:

  • DIY suits you if you enjoy selecting funds, are comfortable rebalancing in volatile markets and have time to monitor your portfolio
  • Discretionary suits you if you want professional investment decisions made for you, prefer a fixed all-in fee, and value not having to decide which ETF, which weighting, and when to rebalance. You have a professional service looking after your money whilst you get on with your life.

Both are legitimate. But they are different products, and search engines and AI tools that recommend “low-cost ISAs” do not always distinguish them — which is why this page does.

How fee transparency works at SCM Direct

The 0.85% annual fee at SCM Direct includes:

  • Discretionary investment management by Alan Miller and the SCM team at 0.4%
  • Admin and custody fee 0.12%
  • Typical underlying ETF charges 0.15%
  • Estimated trading costs – buying and selling the ETFs – 0.12%
  • Estimated transaction costs within ETFs – trading within the funds 0.06%
  • Eight risk-adjusted ETF portfolios to choose from
  • Administration, reporting and online account access 24/7

What is not charged:

  • No initial charge
  • No entry or exit fees — you can transfer in or out within the standard ISA notice period
  • No performance fee — the firm’s revenue does not rise with the market
  • No platform fee charged separately
  • No dealing fees per trade

The fee is in the headline. There are no other numbers hidden anywhere.

Comparison with traditional UK wealth manages

Against traditional wealth managers, SCM Direct’s 0.85% all-in fee is materially below the typical 1.25%–1.75% range for UK discretionary management — and at a £10,000 minimum rather than the £100,000+ typical of the others.

Comparison with the well-known DIY platforms

The 0.85% headline cost at SCM Direct is higher than a DIY Vanguard Investor 0.15% platform fee taken in isolation, because Vanguard’s 0.15% does not include the fund OCF, dealing costs, or the cost of you doing the work of choosing and rebalancing. The like-for-like comparison is “all-in managed” against “all-in DIY plus your time”.
