What is Spread Betting? A UK Beginner's Guide
Spread betting is a leveraged way to speculate on whether a financial market will rise or fall, without owning the underlying asset. In the UK it has a distinctive tax treatment: for most retail traders, profits are currently free from Capital Gains Tax and Stamp Duty, which is part of why it remains popular here despite being largely unknown elsewhere. That tax treatment depends on your individual circumstances and is not guaranteed, as we explain below.
But a favourable tax treatment doesn't mean risk-free. Spread betting is a leveraged product, which means your gains and losses are amplified, and the majority of retail traders lose money. The UK financial regulator, the Financial Conduct Authority (FCA), requires every broker offering spread betting to display this warning prominently, and with good reason.
In this guide we explain what spread betting actually is, how it works in practice, how it is treated for tax, the real risks involved, and what to look for in a platform if you want to try it. We also cover how spread betting differs from buying shares directly and from CFDs, which is the closest alternative product.
What is Spread Betting?
Spread betting is a way to speculate on the price movements of financial markets without ever owning the underlying asset. Instead of buying shares in Tesla or buying physical gold, you place a bet on whether the price will go up or down, and how much money you make or lose depends on how far the price moves in your chosen direction.
The "spread" in spread betting is the difference between the price you can sell at (the bid) and the price you can buy at (the ask). That spread is how the broker makes its money, there is no commission charged on top. You stake an amount per point of movement, and your profit or loss is simply your stake multiplied by how many points the market moved.
A few things make spread betting distinct from other forms of trading:
- You don't own the asset. You never actually own the share, the ounce of gold, or the unit of the index. You're betting on the price.
- It's leveraged. You only put down a percentage of the trade value as margin (for example, 5% on major indices), while your exposure is the full size of the position. This magnifies losses just as much as gains.
- It's tax-efficient for most UK retail traders. Profits are currently free from Capital Gains Tax and Stamp Duty, though this is not guaranteed and depends on your individual circumstances.
- It's UK-specific. Most countries don't have spread betting. It exists because of a quirk in UK tax law dating back decades.
- You bet per point, in pounds. Even on US stocks or gold priced in dollars, your stake is denominated in GBP per point, so you are not converting currency to take the position. Some share-dealing accounts also offer multi-currency holdings, so compare the specific costs of each route.
Is Spread Betting Tax-Free in the UK?
For most UK retail traders, spread betting profits are not taxed. The reason is structural rather than a simple "it's gambling" label: because you never acquire or dispose of an underlying asset, no chargeable gain or allowable loss arises for Capital Gains Tax purposes. This exemption follows from section 51 of the Taxation of Chargeable Gains Act 1992, as set out in HMRC guidance at CG56105. There is also no Stamp Duty, because you do not buy the underlying shares.
This is not an absolute exemption. HMRC's Business Income Manual (BIM22020) is explicit that a spread bet can become taxable where the winnings "arise from the carrying on of that trade" rather than merely from an opportunity presented by a trade. For the overwhelming majority of retail traders this does not apply, but spread betting is more accurately described as usually untaxed than as automatically tax-free.
There is one caveat worth understanding. If spread betting becomes your source of income, HMRC could in theory treat it as a trade and tax the profits. That bar is very high, and court cases that have tested it have usually landed in the taxpayer's favour, but it's worth mentioning for full transparency. If you think you might fall into that category, speak to a qualified tax advisor.
There is also a flip side. For the same structural reason, spread betting losses cannot be offset against any other income or capital gains. The losses are simply losses, with no tax relief available.
This table is for general guidance only. Tax treatment depends on your individual circumstances and can change. Spread betting and CFDs are commission-free at many brokers, but other costs apply (such as the spread, overnight funding and currency conversion), and some brokers do charge commission, particularly on share CFDs.

How a Spread Bet Actually Works
The easiest way to understand spread betting is with a worked example. Let's say the FTSE 100 is quoted at 8,200 to buy and 8,199 to sell (so the spread is 1 point). You think the FTSE will rise, so you place a buy bet at £10 per point.
If the FTSE rises to 8,250 and you close your position:
- Points gained: 8,250 minus 8,200 = 50 points
- Your profit: 50 points multiplied by £10 per point = £500
If the FTSE falls to 8,150 and you close your position:
- Points lost: 8,200 minus 8,150 = 50 points
- Your loss: 50 points multiplied by £10 per point = minus £500
The mechanics are the same whether you're betting on an index, a currency pair, a commodity like gold, or an individual share. Only the point size changes. For UK shares, one point is typically one penny of share price movement; for gold, one point is usually one dollar; and for EUR/USD, one point is typically the fourth decimal place (a pip). Point sizes and pricing vary between brokers and markets, so always check the contract details for your specific market with your broker before you trade.
Your exposure is far larger than your deposit. To open a £10-per-point bet on the FTSE 100 at 8,200, you control a position worth £82,000 (8,200 × £10). Under FCA rules, the broker will require margin of 5% on major indices, meaning you'd need around £4,100 in your account to open the position. A 50-point move against you wipes out £500, or more than 10% of your margin.
Key Spread Betting Terms Explained
A quick glossary of the terms you'll see on every spread betting platform:
- Spread: The difference between the buy and sell price. This is your cost of trading.
- Stake: The amount of money you're betting per point of movement, typically from £1 per point upwards.
- Point: The unit of price movement. Different markets have different point definitions.
- Margin: The deposit required to open a position, shown as a percentage of the total trade size.
- Leverage: The multiple of your margin that you're controlling in the market. FCA rules cap retail leverage at 30:1 for major forex, 20:1 for major indices and gold, 10:1 for other commodities, and 5:1 for shares.
- Stop loss: An order to close your position once the market moves against you by a set amount. It is triggered at that level but filled at the next available price, so in fast-moving or gapping markets it can close at a worse price than the level you set. A useful risk-management tool, but not a guarantee against slippage.
- Guaranteed stop: A stop that closes your trade at exactly the price level you set, even during fast-moving or gapping markets. It comes with a fee (a premium), which typically applies when the guaranteed stop is triggered.
- Margin call: A notification that your account no longer holds enough margin to support your open positions. If you do not add funds or reduce exposure, the broker can begin closing your positions automatically once your margin reaches the regulatory close-out level.
- Overnight funding: A charge applied to leveraged positions held overnight, reflecting the cost of the leverage.
Spread Betting vs CFDs: What's the Difference?
Spread betting and CFDs (Contracts for Difference) are close cousins. Both are leveraged, both let you go long or short, both are regulated by the FCA, and most brokers that offer one also offer the other. The differences are mostly about tax and structure.
Spread betting is a bet. You stake per point, profits are usually free from Capital Gains Tax and Stamp Duty (subject to your circumstances), losses are not deductible, and the product exists only in the UK and Ireland.
CFDs are a contract. You hold a position in lots or units, profits are subject to Capital Gains Tax (but can be offset against other gains or losses), there is no Stamp Duty because you don't own the underlying, and commissions may apply on share CFDs. CFDs are available in most major markets outside the US.
For UK retail traders who just want to speculate on short-term market movements, spread betting is almost always the better choice on tax grounds. CFDs become more relevant if you trade professionally and want to offset losses, or if you want the flexibility to trade in currencies other than GBP. We cover this in more detail in our best CFD brokers UK comparison.
The Real Risks of Spread Betting
Being tax-efficient is not the same as being risk-free, and this point is worth making firmly. The FCA requires every UK broker to disclose the percentage of retail accounts that lose money trading spread bets and CFDs. At Capital.com, that figure is 61%, and across major UK brokers the figure is comparably high. In other words, the typical retail spread bettor loses money.
The main risks to understand:
- Leverage amplifies losses. A 5% move against you on a 20:1 leveraged position wipes out 100% of your margin. This can happen in minutes on volatile markets.
- Margin calls can force you to close at the worst time. FCA rules require brokers to close your positions automatically if your margin falls to 50% of what's needed, which often locks in losses.
- Gaps can skip through your stop loss. If a market closes at 100 and opens the next day at 80, a standard stop loss at 95 will execute at 80, not 95. A guaranteed stop removes this risk for a fee.
- Overnight funding erodes long-held positions. Spread betting is designed for short-term trading. Holding positions for weeks or months eats into your returns.
- It's psychologically demanding. The leverage and the tax treatment can encourage overtrading. Most of the people who lose money are not losing because the product is flawed, they are losing because they overtrade, misuse leverage, or chase losses.
The silver lining for UK retail traders is that the FCA imposes strict protections. Negative balance protection is mandatory, meaning you cannot lose more than the money in your account, even in a market crash. All FCA-regulated brokers must segregate client funds from their own, and accounts are covered by the Financial Services Compensation Scheme (FSCS) up to £85,000 per client if the broker fails.
What to Look For in a Spread Betting Platform
If you decide spread betting is right for you, the platform you choose matters. A few criteria to prioritise:
- FCA regulation. Non-negotiable. Check the broker is authorised by the Financial Conduct Authority and registered on the FCA Register. Avoid any broker regulated only offshore.
- Tight spreads. Since the spread is your main trading cost, wider spreads compound quickly. Compare spreads on the markets you plan to trade, not just on the broker's headline markets.
- Range of markets. More markets means more opportunities. A good spread betting broker should offer thousands of markets across forex, indices, shares, commodities and ETFs.
- Platform quality. Fast execution, reliable mobile app, clean charting, and ideally integration with TradingView for advanced analysis.
- Risk management tools. Guaranteed stop losses and negative balance protection should be standard.
- Demo account. Any decent broker will offer a free demo with virtual funds so you can practice before risking real money.
- Low minimum deposit. So you can start modestly, test the platform, and scale up only if it's working for you.

How to Get Started With Spread Betting
If you've decided to give spread betting a try, here's the sensible way to start:
Pros and Cons of Spread Betting
Is Spread Betting Right for You?
Spread betting suits traders who want to speculate on short-term market movements, are comfortable with leverage, and understand that most retail traders lose money. It is a high-risk, short-term product rather than a long-term investing strategy, and it is not designed for building wealth over the long run. If you are unsure which approach fits your goals, consider seeking independent financial advice.
If you are going to try it, start with stakes you can afford to lose, stay on the demo for as long as you need, and treat the first six months as tuition. The traders who do well with spread betting treat it with the same discipline as any other professional activity. The ones who blow up their accounts treat it like a casino.
Frequently Asked Questions
Is spread betting legal in the UK?
Yes, spread betting is fully legal and regulated. UK brokers offering spread betting must be authorised by the Financial Conduct Authority (FCA), which enforces strict rules on leverage, risk disclosure, and client fund segregation.
Is spread betting really tax-free?
For most UK retail traders, profits are currently free from Capital Gains Tax and Stamp Duty, because no underlying asset is bought or sold. This is not guaranteed: tax treatment depends on your individual circumstances, can change, and may differ if spread betting is your main source of income or you are taxed outside the UK. The trade-off is that losses are not deductible for tax purposes either.
Can I lose more than I deposit?
No, not if your broker is FCA-regulated. Negative balance protection is mandatory for retail clients, meaning your losses are capped at the funds in your account, even in extreme market conditions.
What's the minimum I can bet per point?
Minimums vary by broker but typically start at £1 per point on major markets such as the FTSE 100 and EUR/USD. Some markets have higher minimum stakes.
Is spread betting the same as gambling?
It has historically been treated like a bet for tax purposes, which is part of why profits usually fall outside Capital Gains Tax. Practically, though, it is closer to short-term trading than to betting on roulette. The skill element is higher, and risk management tools like stop losses give you some control over outcomes. But the fact that the majority of retail participants lose money is a reminder that it behaves more like gambling than investing for those who don't approach it with discipline.
Do I need to be a professional to spread bet?
No. Spread betting is open to retail traders with the standard FCA protections. In fact, if you qualify as a "professional" client you lose some of those protections, including negative balance protection, so most retail traders are better off staying classified as retail.
Final Thoughts
Spread betting is one of the most powerful tools available to UK traders, and also one of the easiest to misuse. The tax treatment and leverage make it attractive for short-term speculation, but the statistics on retail losses are a sober reminder that most people who try it don't make money. If you want to explore it, do so with a regulated broker, a demo account, a starting balance you can afford to lose, and strict risk management from day one.
For UK traders ready to get started, Capital.com is our recommended platform. UK accounts are provided by Capital Com (UK) Ltd (FCA reference 793714): no separate trading commission (other fees apply, such as the spread, overnight funding and currency conversion), thousands of markets, a £20 minimum deposit, and a TradingView-powered platform that makes it easy to learn as you go.
Trading involves significant risk and may not be suitable for all investors. The value of investments can go down as well as up, and you may lose some or all of your initial investment. Past performance is not indicative of future results.
Spread betting carries a high level of risk to your capital. You should not spread bet unless you understand the risks involved and can afford to lose the money you invest. Spread bets are complex financial instruments and come with a high risk of losing money rapidly due to leverage. 61% of retail investor accounts lose money when trading spread bets and CFDs with this provider. You should consider whether you understand how spread bets work and whether you can afford to take the high risk of losing your money.
Tax treatment depends on your individual circumstances and may change in future. The tax treatment of spread betting assumes it is not your main source of income, and may differ if you are taxed outside the UK.
