Ah just thought has the property had the cavity filled with insulation recently?
Yes it has I think ?
It was struck by lighting
Not 100% sure but think the floors are concretedCheck that the air bricks are clear? could be there blocked and the structural floor timbers are rotting 1930's bungalow had wooden floors

Has any sockets been removed and put back illegally?
God moves in mysterious ways, joking aside ffw knows his stuff.Funny you should mention it there was a electrician/plasterer there changing a socket and that's when it started cracking ?
There's only one crack outside under a windowI'm leaning towards somthing to do with the roof? The fact that the cracks are up high.If it was subsidence you would expect to see some crackin in corners, corners of windows at lintels? Is there any signs of cracks outside bigfella?

It's hipped I think but these cracks haven't just appeared over the the last few months they are a couple of years oldMy guess would be the wall plate moving. The insulation has allowed the snow to stay on the roof (is stopping it from melting) and the weight of it is pushing down on the roof and pushing the wall plate out.
Is the roof gabled or hipped? I bet its hipped with a shallow pitch.
There won't be cracks outside, the wall plate sits on the inside cavity wall. The outside wall is not supporting the roof.There's only one crack outside under a window
I've just seen you're in Yorkshire, you had much snow over the last decade? LolIt's hipped I think but these cracks haven't just appeared over the the last few months they are a couple of years old
We've not had much snow recently but could still be a factorI've just seen you're in Yorkshire, you had much snow over the last decade? Lol
I will still stand by my post. Wall plate moving
It's a problem which only became visible in the last two years though..?We've not had much snow recently but could still be a factor
