IG UK Offer: Earn Up to £200 Cashback on Your Investments (March 2026)

IG is currently offering 5% cashback on investments for new clients, with a maximum payout of £200. The promotion runs from 23rd February to 13th March 2026, giving new investors a short window to sign up and make qualifying trades. Use promo code CASHBACK200 when opening your account to activate the offer.

Our Verdict

This is a straightforward, predictable promotion. Unlike lottery-style free share offers where your reward is random, IG's 5% cashback gives you proportional value based on how much you invest. The maths is simple: invest more, earn more cashback.

The promotional window is tight, running for under three weeks from 23rd February to 13th March 2026. If you have been considering opening an IG account, this is worth acting on sooner rather than later.

The 3-month holding period is reasonable, especially if you are planning to invest for the long term anyway. You do not need to actively trade during this period. You simply need to maintain an active portfolio.

In practical terms, a minimum investment of £100 earns you £5 cashback. To unlock the full £200, you would need to invest £4,000 or more. For investors looking to open a new ISA or SIPP heading into the new tax year, this could be a well-timed bonus on top of your regular contributions.

How It Works

IG calculates your cashback at 5% of the total investments you make by 13th March 2026. The maximum cashback is capped at £200 per client. Here is how the numbers break down:

• £100 investment = £5 cashback
• £500 investment = £25 cashback
• £1,000 investment = £50 cashback
• £2,000 investment = £100 cashback
• £4,000+ investment = £200 cashback (maximum)

All qualifying investments must be made in shares or ETFs through your IG account. The cashback is then credited to eligible clients in June 2026, after the 3-month holding period has passed.

IG Platform Features

Beyond this promotion, IG offers a solid investing platform for UK clients. The platform charges zero commission on UK stocks and ETFs, which keeps your ongoing costs low. Uninvested cash earns 3.75% AER on balances up to £100,000, so your money is still working for you while you decide where to invest.

IG supports three account types: a General Investment Account (GIA), a Stocks and Shares ISA, and a Self-Invested Personal Pension (SIPP). This means you can use the cashback offer across any of these wrappers depending on your investment goals.

IG also became the first UK-listed broker to offer cryptocurrency trading, adding another asset class for investors who want diversified exposure from a single platform.
