Removing bricks from wall - what's safe

[SouthDrive]

Hello,
My gas supply has been moved and whilst the hole is dug I'm also going to swap the old steel water pipe to a new MDPE pipe,

Id like to repair the brick work by "toothing in" the new bricks.

Is it safe to remove the old damaged bricks without any additional support for the bricks above?

In total I need to cut out a total width of 3 bricks, and a depth of 5 bricks .

Yes! Imagine a triangle, pointing up the wall, with the base of the triangle where you will remove bricks. Only the bricks within that triangle will be at risk of loosening.

I thought it would be okay but wanted to clarify,
Thank you for the quick response

Hello
Thought I would show what I did incase it helps anyone in the future, although the post title is a bit vague.
Replacing the water pipe was the goal,.
1. Dug out and exposed the old pipe
2. Cut out the broken bricks, (grinder and SDS)
3. Removed old pipe, put some Flexi duct in from eBay, put the mdpe in, bricked up the hole
4. Inside, filled the big hole inside with a weak mix (1cem, 8 sand, 8 gravel) finished the top 6" with a stronger mix (1 cem, 4 sand)

5. Should have put a drain off valve on the 22 coppers but the shops were shut so I didn't.

Thanks for the advice Harry
