You can hold gold in a Stocks and Shares ISA through a gold ETC (exchange-traded commodity) — a financial instrument that tracks the gold price, backed by physical gold held in a custodian vault. Physical gold coins and bars cannot go inside an ISA. Within the ISA wrapper, gains on gold ETCs are completely free from capital gains tax, with no limit on the gain and no reporting required.

Why hold gold in an ISA?
The primary reason is the CGT shelter. Without an ISA, gains on a gold ETC are subject to capital gains tax at 18% (basic rate) or 24% (higher rate) above the £3,000 annual exempt amount.
Inside an ISA, those gains are entirely tax-free, regardless of size. For an investor who builds a meaningful gold ETC position over several years at rising prices, the ISA shelter can be worth thousands of pounds in avoided CGT.
The ISA also removes the reporting obligation. Gold ETC gains outside an ISA must be reported via Self Assessment if they exceed the £3,000 threshold. Inside an ISA, there is nothing to report.
1. Gold ETC in a Stocks and Shares ISA
What it is: A gold ETC tracks the gold spot price and trades on the London Stock Exchange. The main physically-backed options available to UK ISA investors:
| ETC | Ticker | Physically backed | Annual charge |
|---|---|---|---|
| iShares Physical Gold ETC | IGLN | Yes — allocated gold | 0.12% |
| WisdomTree Physical Gold | PHAU | Yes — allocated gold | 0.39% |
| Invesco Physical Gold ETC | SGLD | Yes — allocated gold | 0.12% |
| Royal Mint Physical Gold ETC | RMAU | Yes — Royal Mint vault | 0.22% |
All four hold allocated physical gold in third-party custodian vaults. You own ETC units, not specific bars directly. In an insolvency of the ETC issuer, the underlying gold is ring-fenced and returned to unit holders.
Why people choose it: The ISA CGT shelter is the primary driver. Combined with the low annual management charges (IGLN and SGLD at 0.12% are among the cheapest gold instruments available), an ISA-held gold ETC is one of the most tax-efficient ways to hold gold in the UK — second only to CGT-exempt physical Sovereigns.
What to be aware of: You own a financial instrument, not physical gold. Unlike a Gold Sovereign, there is no physical metal you can hold in your hand, store at home, or access if digital infrastructure fails. The ETC structure depends on the custodian holding the gold and the ISA platform operating normally.
Annual management charges compound over time. At 0.12%, the drag is modest — approximately £60 per year on a £50,000 position. At 0.39%, that rises to £195. For very long holding periods, the cheaper options are meaningfully better.
Who this suits: Investors who want gold as part of a portfolio allocation and are comfortable holding it as a financial instrument. Particularly suited to those already using an ISA for other investments — adding a gold ETC to an existing account is straightforward.
2. Physical gold Sovereigns outside the ISA
What it is: Buying Gold Sovereigns or Britannias directly from a UK dealer, outside any tax wrapper. The CGT exemption on UK legal tender coins means gains are tax-free anyway — no ISA needed.
Why people choose it: Physical ownership, no platform dependency, no annual charges, and the same CGT-free outcome as the ISA. For most long-term physical gold buyers, the Sovereign route is both simpler and cheaper than maintaining an ISA for gold.
What to be aware of: Physical gold requires storage and insurance. The ISA’s annual contribution limit of £20,000 is not a constraint you face with physical coins — you can invest any amount. See storing gold at home for the practical considerations.
Who this suits: Investors who specifically want direct ownership of physical metal, or those investing amounts beyond the ISA annual limit.
ISA vs physical Sovereign: the practical comparison
For most UK investors, this is the central question:
| Gold ETC in ISA | Physical Sovereign | |
|---|---|---|
| CGT on gains | 0% (ISA shelter) | 0% (legal tender) |
| Annual charges | 0.12–0.39% ETC + ISA platform fee | None |
| Annual contribution limit | £20,000 | Unlimited |
| Physical ownership | No | Yes |
| Accessible | Sell and withdraw within days | Sell to dealer within days |
| Storage cost | None (within ETC) | Insurance / safe / vault fee |
The CGT outcome is the same. The difference is: the ISA route costs a small annual fee and involves no physical storage; the Sovereign route costs nothing annually but requires physical security. At larger positions, the ISA platform and ETC fees become meaningful — a £100,000 gold position at 0.12% ETC + 0.25% ISA platform fee is £370 per year. Compare that to a specialist vault at 0.12% annually on the same value.
Use the best-deal tool to see current Sovereign prices if physical is your preferred route.
Platforms offering gold ETCs in ISAs
Most major UK investment platforms support gold ETCs in their Stocks and Shares ISA:
| Platform | Notes |
|---|---|
| Hargreaves Lansdown | Full ETC range including IGLN, PHAU |
| AJ Bell | IGLN and SGLD available |
| Interactive Investor | Full ETC range; flat-fee pricing model |
| Trading 212 | IGLN available; commission-free |
| Freetrade | IGLN and others available |
| InvestEngine | ETF/ETC focused; low-cost |
Annual platform charges vary — percentage-based platforms (like Hargreaves Lansdown) become relatively expensive on larger positions; flat-fee platforms (like Interactive Investor) are better value at £50,000+.
ISA vs LISA vs SIPP for gold
These three wrappers are frequently confused. They serve different purposes:
Stocks and Shares ISA: No government bonus, no lock-in, no age restrictions. The most flexible wrapper for gold. Best for investors who want accessible, CGT-free gold exposure without the constraints of a pension.
Lifetime ISA (LISA): 25% government bonus on contributions, but locked until age 60 (or first home purchase), and a punishing early withdrawal penalty. See gold in a LISA for full details. Best for under-40s saving for a first home or retirement.
SIPP: Pension tax relief on contributions (20–45%), but locked until age 57. See gold in a SIPP for details. Best for higher earners adding gold to retirement savings.
For general gold ISA exposure with no strings attached, the plain Stocks and Shares ISA is the right wrapper.
Tax and regulation
CGT inside an ISA: All gains are exempt. No threshold, no reporting. Withdrawals from an ISA are also free from income tax.
ISA allowance: £20,000 per person per tax year (2026/27). The LISA (£4,000) counts separately and does not reduce your ISA allowance. If you also hold a Cash ISA, the limits are shared across all ISA types — the total cannot exceed £20,000.
ISA transfers: If you hold a gold ETC in an old ISA and want to move to a different platform, use an ISA transfer rather than withdrawing and resubscribing — withdrawing and resubscribing uses new annual allowance and cannot recover past years’ allowances.
Bed and ISA: If you hold a gold ETC outside an ISA and want to move it in, you must sell the holding (potentially triggering CGT), then repurchase inside the ISA. This is known as “Bed and ISA.” The CGT event on the sale cannot be avoided unless gains are within the £3,000 annual exempt amount.

Frequently asked questions
Can I hold physical gold in an ISA? No. A Stocks and Shares ISA is a financial investment account. It can hold stocks, bonds, ETFs, and ETCs — not physical assets like coins or bars. Physical gold has no ISA-eligible wrapper.
Which gold ETCs can I hold in an ISA? Any UK-listed, ISA-eligible gold ETC can be held in a Stocks and Shares ISA. The main options are iShares Physical Gold ETC (IGLN), WisdomTree Physical Gold (PHAU), and Invesco Physical Gold (SGLD). All three are physically backed by allocated gold in custodian vaults.
How much gold can I hold in an ISA? As much as you like — within the annual ISA contribution limit of £20,000 per person per tax year (2026/27). You can allocate your entire £20,000 allowance to a gold ETC if you choose, or split it across different holdings.
Is gold in an ISA CGT-free? Yes. All gains on any investment held inside a Stocks and Shares ISA are completely free from capital gains tax. This includes gold ETCs. There is no limit on the gain, and no reporting required.
What is the difference between a Gold ISA and a Stocks and Shares ISA holding gold? There is no regulated product called a “Gold ISA” in the UK. The correct term is a Stocks and Shares ISA that holds a gold ETC. Be cautious of any provider marketing a “Gold ISA” — check whether it is an HMRC-approved ISA wrapper and what the underlying product is.
