LCWRA and inheritance

I am going to inherit around £100k at some point and want to use the money as a deposit to buy a home for me and my family (currently renting) and maybe make improvements to the home if it needs them in order to be a reasonable place to live. If I got the inheritance and reported it to DWP and my UC stopped for a couple of months due to having tipped over the financial threshold and then I spent the money, do I have to go through the whole rigmorale of starting a new claim and being assessed for LCWRA again?
