Hi Kieran....welcome to the Club
Replacement of the air bags is a relatively easy job but you will also have to replace the controller which will now be defunct and code in a new one.
Also, some sensors may have to be replaced also.
Technically, everything associated with the SRS including the wiring loom should be replaced following an incident that has led to the Airbags deploying.
Let us know how you get on with it all
