WELCOME300: free shares for new money
New clients who invest at least £300 receive a bundle of free UK-listed shares worth up to £300, using promo code WELCOME300. It runs through 31 December 2026 and works on a General Investment Account, Stocks and Shares ISA, or SIPP. Full breakdown in our IG free shares guide.
Interest on uninvested cash
IG pays interest on the GBP cash you hold but have not invested, at a standard variable rate it sets and can change, credited monthly. On top of that it runs boosted rates for new clients from time to time, such as the 5.00% AER offer it ran in June. Those boosts are time-limited, so check whether one is live before you fund an account. Full detail in our IG cash interest guide.
Why choose IG?
IG is one of the longest-established brokers in the UK, FCA regulated and listed on the London Stock Exchange, with access to thousands of markets. Outside these offers it runs share dealing, ISAs, SIPPs and more, so the promotions sit on top of a broad, well-run platform rather than being the only reason to sign up.
Frequently Asked Questions
What IG offers are available right now?
IG currently has two separate new-client share offers. WELCOME300 offers a random UK share bundle worth £40 to £300 after a qualifying £300 investment. SEPSHARES250 offers a random US-listed share bundle worth approximately £20 to £250 after a qualifying £50 net investment. The two offers cannot be combined.
Can I get free shares and earn interest on cash?
Cash interest is a separate account feature subject to its own eligibility and terms, so it is not guaranteed for every account or balance. A promotional cash-interest boost has separate conditions and counts as another promotion, so it cannot be combined with SEPSHARES250.
Which account types qualify?
For SEPSHARES250, qualifying investments can be made through a GIA, ISA, SIPP, Smart GIA, Smart ISA or Smart SIPP. IG pays the reward into a GIA, so you need one even if you invest through another eligible account. WELCOME300 covers GIA, ISA and SIPP accounts.
