What Is a Referral Bonus?
A referral bonus is a financial incentive offered by a platform — bank, broker, crypto exchange, or investment app — to both an existing user who recruits a new customer and sometimes to that new customer as well. The bonus can take many forms: cash deposited to your account, fee credits, reduced trading fees for a set period, free stocks, or enhanced interest rates on your deposits.
For example, a neobank might offer you £20 and give your friend £20 when they open an account and make their first deposit. An investment platform might give you both a free share worth up to £100. A crypto exchange might offer a percentage fee rebate on your first trades. The mechanics vary, but the commercial logic is the same: user acquisition through word-of-mouth is cheaper than paid advertising, and the cost is shared with the person doing the referring.
On our institutions directory you can compare referral bonuses across banks, crypto platforms, investment apps, and more — all in one place.
Who Pays for Referral Bonuses?
Referral bonuses are funded from the marketing budget of the platform offering them. Rather than paying for a Google ad or a billboard, the company allocates a portion of its customer acquisition cost (CAC) to referral rewards. Because referred customers tend to have higher retention rates and lifetime value than customers acquired through cold advertising, it is often a favourable trade for the platform.
There is no "free money" hidden agenda here — the money comes directly from the company's marketing spend. The reason platforms can afford to be generous is that digital financial products have low marginal cost per user once the infrastructure is built. A crypto exchange that lets you trade with zero marginal infrastructure cost per additional user can afford to subsidise your first month of fee rebates because your future trading volume more than compensates.
The Main Types of Referral Bonus Structure
Understanding the structure of a referral bonus matters because it determines how much you actually earn and what conditions you must meet.
Fixed cash bonuses are the simplest: you refer a friend, they meet a condition (open an account, deposit a minimum amount, complete a trade), and both of you receive a fixed amount. These are common among neobanks and stock brokers. The key variable is the deposit or activity threshold — always check whether the friend needs to deposit £100 or £10,000 before either of you earns anything.
Percentage fee rebates are popular on crypto exchanges. Rather than a fixed payment, you and your referral share a percentage of trading fees for a defined period. These can be extremely valuable for active traders but worth almost nothing to someone who only trades once. If you plan to trade frequently, look for platforms offering ongoing fee splits rather than one-time bonuses. Check our crypto exchange listings for current fee-rebate referral schemes.
Free asset bonuses — a free share, a small amount of Bitcoin, or a starter deposit — are used by investment platforms and some crypto exchanges. The value is typically randomised within a range (e.g. "a free share worth £3–£200") as a marketing technique that creates excitement. Statistically, most people receive shares near the lower end of the range.
Tiered referral programmes reward you more as you refer more people. Platforms aimed at ambassadors, influencers, or simply enthusiastic users may offer escalating rewards after your fifth or tenth referral. These are worth pursuing if you have a network likely to be interested in the platform.
How to Maximise Your Referral Bonuses
Start with platforms you would use anyway. The best referral bonus is one from a platform you would genuinely recommend, both because you will be more credible and because you will not regret the recommendation if a friend has a poor experience. Read the full review of any platform before sharing your link — use our top-rated institutions list as a starting point.
Read the terms carefully. Most referral bonuses have minimum deposit requirements, minimum holding periods (you may need to keep money invested for 30–90 days before the bonus releases), activity requirements (a minimum number of trades), and geographic restrictions. Failing to meet a single condition often means neither party receives the bonus.
Stack bonuses where possible. Opening accounts with multiple platforms — if you would use them independently — means you can collect several referral bonuses in a short period. Many people cycle through neobank welcome bonuses systematically. This is entirely within the terms of most platforms, provided each account is legitimate and each person only signs up once per platform.
Track your referrals. Most platforms give you a dashboard showing who has signed up via your link and whether conditions have been met. Check it regularly — if a referral fails due to a technical issue, contacting support promptly usually resolves it.
