crack in house wall...

We moved into a house about a year ago.

Shortly after i noticed a few cracks developed on the render on one side of the house. Initially i put it down to just cracked render but it looks a bit suspicious that they eminate up toward that upstairs window.

Also In the bathroom (the other side of that upstairs window) there is a fine crack in one of the tile on the bottom corner of the window (mirroring the crack down toward to the alarm box). This implies movement in the wall to me, not just cracked render.

I have had a good investigation and it looks like all of the rain water form the roof drains into soakaways dotted around the house. The downpipe you see in the first pick just empties into a soak away but i'm not sure how far away from the house it drains (there is a patio outsied those patio doors).

Some background to the local.

- On the left of the first picture is a single story extension to the rear, the pitched roof you can see is a leantoo shed/room with the boiler inside.

- On the right of the first picture is a conservatory

- About 3m infront of the patio doors in the first pic there is a well. I've taken the lid off and the water level is low. The well walls are bricked and look nice and solid. The roof rainwater does not drain into the well.

- About 2m from the well (away from the house) is a swimming pool

What do you think is causing the cracks?

As i see it i have 3 options:

1) Get a surveyor in
2) Get all the guttering sorted so i drains into the mains drain the other end of the house
3) Other

What do you think?

If there are no other cracks, then the location of the cracking suggests some movement of the lintel or some normal expansion of the rear elevation
