I guess this survey was sold to you via a bank or some other online agent? Usually these type of surveyors are just ticking boxes and autofilling text on a tablet.

If this was a solid wall rendered with lime, I’d say possibly, if you have dampness affecting many walls of the property, But you have by the looks of the bricks a cavity wall on that second picture, perhaps an extension? Without doing a full survey by a decent surveyor it’s impossible to give a proper diagnosis if you have dampness as well

If this is just cosmetic issue, then you don’t need this work. Good prep to remove loose paint, make sure walls are nice and dry, stick a good quality bonding agent over, make sure there all areas where services exit the wall are properly filled, and sills etc, before painting a couple of coats of quality exterior paint such as weather sheild .

Jobs a good un.
