If you are doing this for professional purposes you will have to get it done professionally and even if you aren't professional I believe it's like electrical work still illegal to do this yourself.
A professional gas fitter will be able to do all the proper tests etc and write a new certificate for the installation that are required after fitting new parts etc.
For example any insurance you would have on your property would be invalid if something went wrong.
