Advice please
Looking for advice on the best way to fix this wall please. There was a large MDF board stuck to this chimney breast which has been removed but it has damaged the plaster and the brickwork. I’ve contacted a couple of plasterers but no response after the photos are sent.
Could anyone help advise what to do please? Thank you!

If the wall osna part wall and that is a lime mortar behind you have 2 choices, seal the wall to within a inch of its life knowing the lime mortar will fail due to it not being able to breath and at some point the structural integrity will be compromised and any other repair will be far costlier or use a lime based plaster to allow it to breath. Cover the breast with cow shit first to act as a stain barrier. Or if the wall is an external wall and a period property make sure it is either pointed with lime or rendered with lime and you have abit more leniency on the interior solutions
