From Monzo's mystery cash reward of up to £100, to Tide's £50 business account credit, to Amex's 6,000 Avios sign-up bonus, there's real value to be claimed if you're opening a new account or getting a new credit card. All the financial services listed here are FCA-regulated, giving you consumer protection under UK financial regulations.
Best UK bank account deals in 2026
The best bank account deal depends on what you need the account for: current or savings, personal or business. Across the providers we cover, the sign-up saving comes from refer-a-friend rewards rather than public codes: Monzo's £20 to £100 mystery cash, Tide's £50 business credit, Yonder's bonus points, and the BA American Express Card's 6,000 Avios. None of them issue checkout discount codes.

What are the best UK bank account deals in 2026?
The best UK bank account sign-up deals come from refer-a-friend rewards, not discount codes. Monzo pays a £20, £50 or £100 mystery cash bonus, Tide pays £50 in business account credit, Yonder gives bonus points and money off, and the British Airways American Express Card gives 6,000 Avios after £2,000 of spend. None of these run public voucher codes, so the referral reward is the sign-up saving.
