For UK investors, the choice between silver and gold is largely determined by tax treatment: silver attracts 20% VAT on physical purchase; gold does not. This single structural difference means that silver needs to appreciate significantly just to return the VAT on entry - before any real profit is made.
Beyond VAT, the comparison involves different volatility profiles, industrial demand dynamics, and different CGT positions depending on the specific products.
At a glance
| Gold (Sovereign) | Silver (Britannia, physical) | |
|---|---|---|
| VAT on purchase | 0% | 20% |
| CGT on gains | Exempt (legal tender) | Exempt (legal tender) |
| Typical volatility | Moderate | Higher |
| Inflation hedge history | Long, fairly consistent | Shorter, more mixed |
| Industrial demand component | ~10% of demand | ~55–60% of demand |
| Gold-to-silver ratio (March 2026) | ~140:1 | - |
| Minimum entry cost (CGT-free) | ~£480 (Half Sovereign) | ~£30 (Silver Britannia) |
| Annual production growth (supply) | ~1–2% | ~1–2% |
The VAT problem for silver
This is the most important factor and deserves direct treatment.
A Silver Britannia costs approximately £32 including 20% VAT at current prices (approximately £27 spot + 4% premium + VAT). If you buy 100oz of silver for £3,200 (£2,700 in silver content), you have paid £534 in VAT upfront.
For that purchase to break even, silver must rise from approximately £27/oz to approximately £32.50/oz - a 20% gain - before you are back to the equivalent of buying at spot.
Gold does not have this problem. A Gold Sovereign purchased at 5% over spot recovers that premium as soon as gold rises 5%.
Silver can still be a worthwhile investment for UK buyers - the industrial demand case is real, the upside potential in a bull market is higher than gold, and the Silver Britannia is CGT-free. But the entry hurdle is materially higher.
CGT comparison
| Product | CGT status |
|---|---|
| Gold Sovereign | Exempt (UK legal tender) |
| Gold Britannia | Exempt (UK legal tender) |
| Silver Britannia | Exempt (UK legal tender) |
| Silver bar | Taxable |
| Silver Maple Leaf | Taxable (not UK legal tender) |
| Gold bar | Taxable |
Both Gold Britannias and Silver Britannias are CGT-free. Silver bars are taxable. This is identical to the gold position - coins vs bars have different CGT treatment in both metals.
Volatility: silver moves more than gold
Silver is more volatile than gold by a significant margin. Annual standard deviation of silver returns is typically 25–35%, versus 15–20% for gold.
Silver tends to:
- Fall further than gold in risk-off environments
- Rise faster than gold in precious metals bull markets
- Underperform gold during economic contractions
- Outperform gold during inflationary surges with strong industrial demand
The gold-to-silver ratio - the number of ounces of silver needed to buy one ounce of gold - typically ranges between 50:1 and 100:1 over long historical periods. At approximately 140:1 in March 2026, silver is historically cheap relative to gold by this measure. This does not guarantee ratio reversion, but it is the structural argument made by silver bulls.
Industrial demand: silver’s distinguishing feature
Approximately 55–60% of silver demand is industrial - compared to around 10% for gold, which is dominated by investment and jewellery. Key silver industrial applications:
- Solar photovoltaic cells: Silver is used in the conductive paste in solar panels. Global solar installations are growing significantly, and silver use per panel, while declining gradually, remains substantial.
- Electric vehicles: EVs use approximately twice the silver content of conventional vehicles in electrical systems.
- Electronics and semiconductors: Silver is a preferred conductor in a range of applications.
- Medical devices: Silver’s antimicrobial properties drive growing medical use.
This industrial demand backdrop provides a structural demand driver that gold does not have. It also means silver’s price is partly influenced by global industrial activity and economic cycles - which can be a headwind as well as a tailwind.
Who tends to choose silver
Investors who accept higher volatility in exchange for higher upside potential in a precious metals bull market. Silver historically rises more than gold when conditions favour both metals.
Investors who believe the gold-silver ratio will revert toward historical norms. If the ratio moves from 140:1 to 80:1 - either through gold falling or silver rising - holders of silver would significantly outperform gold holders.
Investors who want to hold physical precious metals at a lower unit cost. A Silver Britannia at £32 gives physical ownership at a fraction of the cost of a Half Sovereign at £480. For buyers who want to hold the actual metal, this matters.
Who tends to choose gold
Investors prioritising capital preservation with less concern for speculative upside. Gold has a longer, more consistent track record as a store of value during crises.
Investors who want to avoid the VAT problem. The 20% VAT on silver is a meaningful structural headwind. Gold avoids it.
Investors with larger positions. For a £50,000 precious metals allocation, paying £10,000 in VAT upfront on silver is a significant cost. Gold at the same size pays no VAT.
Tax and regulation
Gold (Sovereign/Britannia): VAT-exempt. CGT-exempt. No regulatory constraints.
Silver Britannia: 20% VAT on purchase. CGT-exempt (UK legal tender).
Silver bars: 20% VAT on purchase. CGT taxable on gains. The least efficient combination for UK buyers.
Silver VAT workaround: Bonded vault storage (e.g. BullionVault Zurich) defers or eliminates UK VAT on silver. See our bonded vault guide.

How people usually decide
Most UK investors who hold precious metals start with gold and add silver later - once they have established a gold position that is tax-efficient and they want additional speculative exposure to the metals complex.
A common approach: core position in Gold Sovereigns for capital preservation and CGT efficiency, with a smaller satellite position in silver for higher-volatility upside potential, accepting the VAT drag as the cost of entry.
Pure silver positions held at meaningful size in physical UK coins are relatively unusual for this reason. The VAT headwind is too significant as a primary allocation for most investors.
Frequently asked questions
Is silver a better investment than gold? Not objectively. Silver has higher upside potential in bull markets and a different demand structure (more industrial). Gold has better tax treatment in the UK, lower volatility, and a longer track record as a crisis hedge. The right choice depends on your objectives.
Why does silver have VAT but gold does not? Investment gold is VAT-exempt under EU VAT Directive rules that the UK retained post-Brexit. Silver is classified as an industrial commodity, not an investment good - so standard 20% VAT applies.
Is the gold-to-silver ratio a reliable indicator? It is a widely watched metric. Historical averages have been 50:1 to 80:1 over long periods; the current ~140:1 is high by historical standards. Whether the ratio reverts, and on what timescale, is not predictable.
