Broker sign-up bonus: free shares up to £500 for new clients

What a broker sign-up bonus actually is

A broker sign-up bonus is a real share or cash credit paid by a regulated broker for funding a new live account. Open the account, deposit £500, get £40 in NVDA shares. That's the deal — below is the small print that decides whether the bonus actually lands.

Today every offer on this page is a free real share — an actual fractional or whole position in a listed company, credited to the portfolio. The same mechanic also covers cash welcome credits, platform fee waivers and premium-tier upgrades; if those go live, they get listed using the same card shape.

The qualification pattern is consistent across formats:

1. Open an account via the partner link.
2. Pass KYC verification (ID + proof of address).
3. Make a qualifying first deposit in GBP.
4. Keep the capital on the account for the holding period (typically 90 days).
5. The sign-up bonus lands — usually within 7 days of conditions being met.

What a sign-up bonus is not: a trading-credit you have to wager, a CFD position, a discount on commissions, or a demo balance. The deposit stays yours from day one; the only constraint is keeping it parked for the stated period.

Worked example: how much £1,000 actually yields

The headline £40-to-£500 number is the share's value at crediting. Translated to yield on your deposit — and to an annualised figure factoring the 90-day holding period:

The 10% peak yield is the eye-catching number. Honest version factors in (a) market risk on the share between crediting and sale, (b) the 90-day cost of capital on the deposit, and (c) any trading or FX fees if you sell into a non-GBP currency. None of those usually wipe the bonus out, but they make the all-in return more like 6–8% net if you sell promptly, and 0 to 15% if you wait and the share moves.

Common pitfalls (and how to avoid them)

The reasons people end up bonus-less, ranked by how often we see them in broker support threads:

1. Registered via the wrong route — estimated 30–40% of failed claims. Typing the broker URL into the address bar, or clicking an organic Google result, doesn't enrol the account. The qualifying step is the partner link. Once registered without it, closing and re-opening on the same ID won't fix the record.
2. VPN at signup — estimated 15–20% of failed claims. UK-only offers reject accounts opened from a non-UK IP even when the KYC documents are British. Turn the VPN off before clicking the partner link and keep it off until KYC is approved.
3. Deposit short of the qualifying floor — estimated 10–15%. £499 is not £500. Currency conversion on non-GBP funding cards can clip the figure; use a GBP transfer for predictability.
4. Withdrawing the deposit before day 91 — estimated 10%. Even a partial withdrawal that takes the balance below the qualifying tier kills the bonus. Plan with money you can park for the full quarter.
5. Incomplete KYC — estimated 10%. Proof-of-address documents must be issued within the last 3 months. A 6-month-old utility bill won't pass even though it's still your address.
6. Dormant old account — estimated 5–10%. Including one from 2017 you forgot about. Brokers cross-check date of birth + first three letters of surname, so old accounts under maiden names get caught too.

How brokers actually fund these bonuses

A £40 share to a new client isn't charity. To understand why it's possible, the unit economics of online brokerage:

Customer acquisition cost (CAC) for a funded retail brokerage account in the UK ranges from roughly £60 to £300+, depending on channel. Paid search for "best stockbroker" sits at the top of that range; affiliate-driven signups via comparison sites are lower. Brand search and word-of-mouth are cheapest, but the volume is finite.

Against that, the lifetime value (LTV) of a funded account is typically £200 to £1,500+ over 3 years, blended across active traders, buy-and-hold investors and dormant accounts. The split is brutally power-law: a small minority of active traders generate the bulk of revenue (spread, FX conversion, premium-tier subscriptions, interest spread on uninvested cash), while the median client trades a handful of times then goes quiet.

A £40 share given to a new £500 depositor reads three ways from inside the broker:

• Cheap CAC. £40 + a few quid in operational cost is below the paid-search alternative; the broker is buying a funded account directly instead of paying Google for a click that may or may not convert.
• Cash-flow positive on day one. The qualifying £500 deposit immediately funds the bonus payout — the broker isn't out of pocket waiting for revenue to catch up.
• Behavioural anchor. A client who's already received a share is statistically more likely to make a second deposit and a first trade within 30 days. The bonus isn't just acquisition — it's onboarding activation.

The bonus is therefore an acquisition spend that comes back through the same client's trading activity. The broker isn't subsidising the new client; the new client is, on average, funding their own welcome gift over the months that follow. Knowing that doesn't make the bonus any less real — but it does explain why "free share" offers are sustainable rather than a fluke.

How we test these offers

Every broker sign-up bonus on this page is manually verified before it goes up. We open the broker's onboarding flow as a fresh prospect, walk through the asset picker and the deposit prompt, and confirm the bonus terms still match what the broker's published T&Cs say. We re-check current offers every 7 days and re-verify the T&Cs text against the broker's domain — not against a cached version on a comparison site.

How we get paid (and why it doesn't change this list)

BrokeRewards earns a commission when you open an account through the orange "Claim" button. The broker pays the same commission whether we rank their offer first, last or in the middle of the page — placement is not negotiable. We list one card per asset in the same alphabetical-by-asset order the eToro picker shows them; tiers and deposit thresholds are the broker's published numbers, not editorial choices.

What we won't do: list an offer we think is misleading (assets that take months to credit, undisclosed eligibility carve-outs, "deposit before midnight" pressure marketing) even when the affiliate rate is high. If a card disappears from this page, the offer ended or we couldn't reverify it within our 7-day check cycle.
