Advice on internal brick wall

[Gizmo101@]

Renovating a bedroom and some old lime plaster is loose with cracks. Have chipped it off hoping to just patch it up with plasterboard etc however under the window there a couple of loose bricks, v badly put in. Outside bricks are absolutely fine.

Any advice on sorting? Thinking to just get the loose bricks out, put new ones in and re-brick the small area. But not sure if more support might needed given it looks like some bricks have already pulled away.

No weight under sill so when ground moves that's the area that moves first.
Just point up

Cheer. Would you suggest putting some support directly under the sill?

The window board would be plastered in and probably also mechanically fixed. The plastic window frame would be fixed into the surrounding brickwork so no need for any support. Rake out the joints and roughly refill before a coat of render ready for refinishing; OR, after a rake out, apply the render pushing it well into the raked back joints, then refinish to match surrounding plasterwork.
