The minimum amount needed to invest in gold in the UK depends on the method. Digital gold and vaulted platforms allow purchases from approximately £25. A half sovereign costs around £480. A full Sovereign runs close to £950. The right entry point depends on your budget, the tax efficiency you need, and whether you want to hold physical metal or a digital claim.

|---|---|---|---|---|
| Royal Mint DigiGold | ~£25 | Taxable | None | No |

Option 1: Digital and fractional gold (~£25 minimum)
What is it?
Royal Mint DigiGold and similar platforms let you buy fractions of gold in grams or milligrams. You own a digital claim on allocated gold, not the physical coins or bars directly.
Why people choose it
Lowest possible entry cost. No handling or delivery concerns. Easy to set up recurring purchases.
What to be aware of
DigiGold is not CGT-free. Unlike a physical Gold Sovereign or Britannia, DigiGold is not classified as UK legal tender. Gains are taxable capital gains. Also: Royal Mint DigiGold charges a 0.5% annual storage fee. Small positions face proportionately high costs.
Who this suits
Complete beginners who want exposure to gold prices with a tiny budget. Not the most tax-efficient route for UK investors expecting gains.
Option 2: BullionVault (vaulted gold, ~£50 minimum)
What is it?
BullionVault lets you buy gold by the gram in professional vaults in Zurich, New York, Singapore, Toronto, and London. You own allocated gold in your name but cannot take delivery below a full bar (approximately £400,000 at current prices).
Why people choose it
Very competitive pricing - typically 0.5% commission on purchase and 0.12% annual storage - with no practical minimum. It suits steady accumulation, and the marketplace structure means you can sell to another user without going through a dealer spread.
What to be aware of
Gains are taxable: BullionVault gold is not UK legal tender. The platform is not FCA-regulated as a financial product, though client metal is segregated and off BullionVault’s balance sheet. Physical delivery requires owning at least one full LBMA bar (400 oz), so most retail holders never take delivery.
Who this suits
Investors who want low-cost gold exposure without CGT-free coins, or who want to build a very large position at tight premiums. Often used alongside physical coins.
Option 3: 1g gold bar (~£145)
What is it?
The smallest widely available physical gold bar. Usually comes in an assay card from PAMP or similar refinery.
Why people choose it
Physical ownership. Gifting. Entry point for buyers who specifically want to hold the metal.
What to be aware of
Premium over spot is extremely high - 25–35%. The gold price must rise substantially before you break even. CGT applies on any gain (bars are not legal tender).
Who this suits
Gifting, not investment. For accumulating gold, 1g bars are an expensive way to do it.
Option 4: Quarter or Half Sovereign (~£480)
What is it?
A fractional Sovereign. Contains 0.0589oz (quarter) or 0.1177oz (half) of fine gold. CGT-free as UK legal tender.
Why people choose it
The lowest price point at which you can buy CGT-free physical gold. Half Sovereigns are the most common choice in this range.
What to be aware of
Premium over spot is higher than a Full Sovereign - typically 5–9% for a Half versus 3–6% for a Full. You pay more per gram to get the lower entry price.
Who this suits
Buyers who want CGT-free physical gold but cannot comfortably commit £950 to a Full Sovereign at once. Also good for regular monthly purchases in smaller amounts.
Option 5: Full Sovereign (~£950)
What is it?
The standard CGT-free gold coin for UK investors. 0.2354oz of fine gold. Tight premiums (3–6%), very high dealer liquidity.
Why people choose it
The combination of CGT-free gains, no VAT, and the tightest spreads of any physical gold product makes this the default starting point for most UK buyers.
What to be aware of
Requires committing approximately £950 per coin. This is the main barrier for buyers on a limited budget.
Who this suits
Most UK investors building a physical gold position. The tax efficiency and liquidity make it the most practical choice once the budget allows.
Option 6: Gold Britannia (~£3,940)
What is it?
A 1oz, 24-carat gold coin. CGT-free. The largest standard single coin for UK retail gold investors.
Why people choose it
Clean whole-ounce position tracking. Same CGT-free status as the Sovereign. Slightly tighter premium at the 1oz level compared with a Full Sovereign.
What to be aware of
High per-purchase cost. Better suited to investors with larger lump sums to deploy.
Who this suits
Investors deploying larger sums who prefer whole-ounce positions and want the CGT exemption at the 1oz price point.
The premium drag problem at small sizes
The smaller the gold product, the larger the premium as a percentage of the gold’s value. This means you are effectively paying more for the same gold.
| Product | Cost | Gold content value | Premium cost |
|---|---|---|---|
| 1g bar | £145 | ~£110 | ~£35 (32%) |
| Quarter Sovereign | ~£480 | ~£224 | ~£256 (14%) |
| Full Sovereign | ~£950 | ~£894 | ~£56 (6%) |
| 1oz Britannia | ~£3,940 | ~£3,800 | ~£140 (4%) |
The Full Sovereign is the most cost-efficient option among physical CGT-free products. Below that size, premium drag increases sharply.
Tax and regulation
CGT exemption: Only UK legal tender coins (Sovereigns, Britannias, and other qualifying coins) are CGT-free. Bars, DigiGold, and vaulted account products are taxable.
VAT: All investment gold products listed above are VAT-exempt at purchase. The VAT issue is significant for silver but not gold.

How people usually decide
Most buyers start with their budget and work backwards. If £950 is manageable, Full Sovereigns are usually the right choice. If not, Half Sovereigns maintain the CGT exemption at a lower cost. If the budget is under £400, a vaulted account product (BullionVault or DigiGold) gives gold price exposure with minimal upfront cost, though without the CGT exemption.
Frequently asked questions
What is the cheapest way to invest in gold in the UK? BullionVault or Royal Mint DigiGold allow investment from around £25–£50. These are digital/vaulted products - you own a claim on gold but not physical coins in your hand. For physical CGT-free gold, a Half Sovereign (~£480) is the lowest practical entry point.
Is DigiGold the same as buying physical gold? No. DigiGold gives you a digital record of ownership of allocated gold in the Royal Mint’s vaults. You do not have a specific coin or bar. You cannot take delivery below a full bar. And it is not CGT-free.
Can I invest in gold with £100? Yes - through BullionVault or DigiGold. At that level, a 1g bar is possible but carries a very high premium. Physical CGT-free coins start at approximately £480.
