Yes you will need an air brick or an air vent.
As far as i know the fireplace was bricked up when it was originally removed and has never been used since.
Lay the brick on the floor of the fireplace flush with the front of the fireplace.
Wipe away the excess and repeat with another brick.

There s no problem blocking up plastering a redundant fire place but you should ensure the chimney top is closed off to water ingress plus it is best practice to vent the flue space so as to avoid condensation forming.
We have been told by one builder that now that the chimney breast has been bricked up we would need an air brick in it to allow ventilation and prevent damp but another builder has said that we do not need an air brick with the chimney being flued and with a cowl fastened to it and cemented in place.
I did a grant job in kirklees it was in their standard spec to brick up bedroom fireplaces and insert a vent.
I m bricking up an unused fireplace in a house about 30 years old.
With regards to the above comment if you put an air bick in the stack externally with the fireplaces still bricked up you will have more condensation problems.
Blocking up an unused fireplace after an old fire surround and hearth has been removed the hole in the chimney breast can be bricked in to tidy up the wall.
It s worth noting that although the chimney stack was originally outside there has subsequently been an extension built on the far side so the stack is now internal for most of the way up until about 2 3rd of the way up the second storey.
