No such thing as an "RCCD". RCD is a generic term which covers a number of devices, including RCCBs and RCBOs, as well as SRCDs etc. MCBs have not been called that - but merely circuit breakers - since 2008.

The terms "RCCD" and "MCB's" are ones that is in common usage and whilst they might not be technically correct, this isn't a technical forum and as long as the posters giving advice know what is being referred to, what's the problem?

For something that hasn't been called an MCB  since 2008, there are an awful lot of places advertising and selling them.
Here's just a few:
MCB (Miniature Circuit Breakers) Guide - Types, Sizes and Uses | RS Components (rs-online.com)
Mini Circuit Breaker | MCB | Schneider Electric, Wylex & More (toolstation.com)
MCB Types – Miniature Circuit Breakers - Techna - UK
MCB Selection Guide | TLC Electrical (tlc-direct.co.uk)

"RCCD" is not in common usage. It doesn't mean anything, and has never been a recognised term. As I pointed out RCD and RCCB are actual terms - RCCD is not.

And as for MCBs - this term has not been recognised since the 16th Edition was withdrawn. It is used in other national standards (e.g. ET101/I.S. 10101), but BS7671 recognises no such term. They are now simply circuit breakers.

And technically "light bulbs" are lamps but that doesn't stop people calling them bulbs. Get off your high horse, you're clearly struggling with the thin atmosphere at that height.
