Ulster Bank’s current notes all share a rather plain design of a view of Belfast Harbour flanked by landscape views; the design of the reverse is dominated by the bank's coat of arms.
The principal difference between the denominations is their colour and size. Notes issued from 1 January 2007 feature the Royal Bank of Scotland "daisy wheel" logo, adopted by Ulster Bank in 2005.
In November 2006 Ulster Bank issued its first commemorative banknote – an issue of one million £5 notes commemorating the first anniversary of the death of Northern Irish footballer George Best. This was the first Ulster Bank banknote to incorporate their new logo and the entire issue was taken by collectors within hours of becoming available in bank branches.
Ulster Bank plans to release a new series of polymer banknotes in 2019, while also replacing its paper notes currently in circulation.
