When my parents were flooded out in Carlisle in the January 2005 floods they were out of their house for over 10 months. ~5 feet of water in the house.
There was still work outstanding when they moved back in October. Once they occupied their own house and the rental house wasn’t being paid for by the insurance company, everything pretty much ceased to happen and my parents gave up fighting. My mam nearly had a breakdown because of this
It’s still not right 11 years later.
They’ve been flooded again in December courtesy of Storm Desmond and are in rented accommodation again. ~6 feet of water in the house this time.
Dehumidifiers are in, kitchen, skirtings, door frames, plaster, etc have all been ripped out and they’re just waiting for it to dry before work starts. IIRC it was ~2 months of drying before anything meaningful started happening.
My advice is to be vocal with the insurance company but don’t be in a rush to move out of the rented accommodation that they’re paying for and use it as a big lever to get things done right.
