You can install the electrical component directly onto a brick or plaster wall. Ensure that all devices are engaged correctly on the DIN rail. It is because split load consumer units provide protection against overload, overcurrent & short-circuit and earth leakage. Although more expensive than a consumer unit with one or two RCDs and separate circuit breakers, RCBOs have the advantage that a fault will only affect a single circuit. Good to know: According to IET (Institution of Engineering and Technology) wiring regulations: 17th Edition (BS 7671:2008 1: 2011), an RCD protection must be provided in the consumer unit except smoke and burglar alarms system.
