anyone have any idea how to fix this? I had a plumber chip it away cause of an old tap that burst and replaced the pipe inside and tap. Attached are photos for reference. Would it be OK to just use brick mortar to fix this?

Brick mortar would be fine. I would start by drying the area and cleaning it up. Be sure there are no leaks, It needs to stay dry otherwise you will have mold and other problems. You may have to place something in the back of the hole to keep the brick mortar from falling down the back side. Then fill the hole with fresh brick mortar and trowel the surface smooth. If you do not have anything else to patch you can get one of the already made brick mortar from your favorite box store.

the best fix would be to replace the whole brick but that will be tricky. patching the hole with mortar is much easier.

I would use a suitable UV-resistant expanding foam to fill such a hole. When the foam expands, it may fill places that you can't reach. Once it dries, it is generally easy to trim the excess with a knife. And, unlike mortar, it won't crack or chip away.
