Best Investment Sign-Up Bonuses UK 2026: Earn £940
The best investment sign-up bonuses in the UK for 2026 are worth £940 across 11 verified offers. Top earners: Shepherds Friendly ISA (£270 profit) and Scottish Friendly ISA (£260 profit), two Friendly Society offers you won’t find on the usual roundup sites. Also worth claiming: Charles Stanley (£110 via TopCashback), J.P. Morgan (£75), and Santander (£50). ISA offers must be opened before 5 April 2026 to use this tax year’s allowance. Based on 11 verified offers tracked by Quidsy, March 2026.
£940 is more than half a year’s energy bill for a typical UK household. And here’s the thing: the two highest-paying offers on this page come from Friendly Societies, mutual organisations that have been around since the 1800s. They don’t show up on most of the roundup sites we looked at. That’s £530 in combined profit hiding in plain sight.
Every offer below has been verified, with net profit calculated after deposit costs. You’ll need cash upfront to trigger each reward, but those deposits stay yours. Withdrawal timelines vary by offer, so check the terms on each one before you start.
Deposits start at £25 for Penfold and go up to £1,000 for Wealthify, so there’s something here whatever your budget. You don’t need to do them all at once. Pick one, complete it, and move on to the next when you’re ready.
Sounds too good to be true? It's not. Banks and brokers spend millions on ads every year. Sign-up offers are just them spending that money on acquiring you directly.
