I'd like to raggle the brick wall in my bathroom to accept a 15mm pipe

What is the best method to cut the raggle?

Oh, now there is a term I had not heard before ;-) I guess you mean how
do you cut a chase...

I tried a bolster and hammer, but think I'm likley to knock the wall
down using this method!

It will work, but is 'kin hard work if the bricks are hard. Wall chaser
or SDS are your best bets. Detail covered he

If you are going to try the angle grinder approach then read the
warnings about dust and take note! You can reduce the dust created a
little by having an assistant position a vacuum nozzle just under the
cutting disc for you as you work.

Failing that, the wall chaser that Cicero linked to (its the model I
use) will make practically no dust at all if hooked up to a decent vacuum.
