I live in a leasehold flat, I recently had 2 major leaks in my bathroom that required my whole shower to be removed as an emergency. I’ve contacted the management agency about building insurance as one of the leaking pipes doesn’t serve my flat just travels through it, still heard nothing back though….
My lease has a vague permission for alterations clause and I will contact them when I have a plan for a new shower (currently waiting for everything to dry out!)
However, while I was looking into whether there’s an official way you ask permission I’ve freaked myself out with stories of people getting their flats repossessed for not asking permission for things and technically I never asked permission to remove my shower/make a hole in the wall to get to it. Does it being an emergency change anything? If it makes any difference the management company are very uninvolved, they take the service charge and that’s pretty much it. Thanks from an anxious first time homeowner!
