Yeah, it's a complex one; if it didn't leak during work then it may have been fine for 30 years. But no bad thing to have it updated. Unless I end up with a plastic box. Was hoping to get front garden sorted, nice new front wall, fix the pointing, put windows back to Victorian sashes etc. If there's a big plastic box on the wall I'd be less inclined to bother. We'll see. At least nobody exploded!
