Cracks and mould in new house

[Adam]

I'm in the process of moving, early days so far and I am yet to have a survey. One area of concern are the following cracks in the house. The first picture is in the kitchen on the ground floor:

Ignore the bodge job on the right hand side with the wood, we'll replace that with plaster.

The next set of cracks are on the wall which had a conservatory added in the past 5 or so years:

The final set of cracks are in the bedroom, on the wall shared with the en suite.

Are any of these any concern? Probably hard to say but you can't fit a coin in them, I'm thinking they are purely cosmetic and the current owners have just been lazy but it would be good to seek further opinions ahead of the hom******s report.

Also, we noticed some nasty mould in the main bedroom (which shares the room with the ensuite) and I can't work out if the mould is coming from outside or is caused by poor ventilation from the en suite (currently no extractor fan).

So some more information, the house was built circa 1995 but I'm not sure if it's a timber frame. The outer walls are solid brick rather than plasterboard but I'm not sure beyond this.

The boiler was replaced around 6 years ago, I stuck my head underneath and it looks like they needed access to it. There wasn't any signs of anything wrong, just bodged back together. The house is pretty dirty and knocked about so we need to spend time and money on it but we are comfortable doing so. Should be decent once we have finished.

As for the mould, I stuck my hand above the window outside and everything felt fine. There wasn't any damp or gaps so I'm hoping an extractor fan and better ventilation would fix it.

So there are no cracks outside, we had a good look around the property once we saw the cracks inside and couldn't see anything other than the visible cracks I took the pictures of at the top of the walls.

What else can I check when I next visit? The reason I went for the hom****** report is that my lender doesn't offer one, we would need to commission our own one on top of what we would already be paying for. We haven't exchanged yet.
