When you communicate information to a customer, you must take reasonable steps to communicate in a way that is clear, fair and not misleading (COB 2.1.3 R).
You should consider your customer's knowledge of the particular investment business that the communication relates to and make reasonable steps to ensure that the communication is clear, fair and not misleading (COB 2.1.4 G).
All types of communication are covered by this requirement (COB 2.1.5 G), for example:
COB Section 2.1 does not apply to a firm when it communicates a financial promotion, when COB Chapter 3 will apply instead (COB 2.1.1 R). In other words, you have broadly similar obligations whether the communication is a financial promotion or not.
