Best UK investing and crypto deals in 2026
The best investing deal is usually the platform with the lowest fees for your strategy, not a discount code. Across the platforms we cover, the sign-up saving is a refer-a-friend reward: Trading 212's free share (£8 to £25 in 80% of cases), InvestEngine's £20 to £200 bonus and Bitcoin rewards from Ledger and Bitrefill. Only Ledger runs genuine public hardware sales; the rest have no public codes.

Trading 212 gives a free share worth £8 to £100 (£8 to £25 in 80% of cases), InvestEngine gives a £20 to £200 investment bonus, and Bitrefill and Ledger pay Bitcoin rewards. Ledger also runs seasonal hardware sales; the others don't issue public codes, so the referral reward is the saving.
