Increase in cracks in property - Possible Subsidence?

I have recently been noticing an increase in a number of cracks that have been appearing in my property. The majority are standard hairline cracks in the ceiling, but there are a number that are concerning.

Firstly, there is a crack on the rear of the property (south facing) that runs along the mortar line. It doesn't appear to start from either a window or door, windows aren't sticking nor is it wider at the top than the bottom. A builder has taken a look and believes it to be a thermal crack, but I'm hesitant to get it repointed if it's part of a wider problem.

Incidentally I've recently had the roof repointed, and the workman noted that there was a gap above the guttering in the roof big enough for him to put his hand through, which explains some interior damage we have found. Another photos shows where there has been some leak damage on the ceiling/wall which also has some cracking along the plaster.

The window nearest this gutter has some cracking around where the frame joins the wall, and the same is happening in the kitchen underneath on the same south facing wall, there is also a crack along the skirting board in the living room, on the same wall.

The final photo is a crack around the front door which goes around the entire frame on the wall.

I imagine the most obvious answer will be to simple get a surveyor round through my home insurance, but thought I'd check if anyone could say categorically either way before claiming on the insurance and it to not be an issue.
