My builder has just installed these velux windows. Velux say the gap between the tile and flashing kit should be between 30 and 60mm however the gap is clearly more in the photos below. The builder says it's the best he can do with the tiles. I would be really grateful if someone could offer some advice on how this can be achieved.
Cutting in velux windows to concrete tiles

Jesus, where to start. 
Pic 1 big black hole, presume tile is kicking up too much.
Flashing not sat properly, as the moulded upstand should have no gap.
Some folk mortar the sides, where the tiles are cut, but yours look to big to do this.
Pic 2 flashing is not sat properly/distorted. flashing should slot on Top of each other, not skew whiff.
Pic 3 same as 2.
Pic 4 same as 2
pic 6 flashings overlapping as windows are too close together. I’ve not seen this done before, but I’m no expert.
He’s right that sometimes depending on tiles used, you can’t get the sides the same distance away from the window.

Horrific tiles (Marley Anglia..?). Poor builder.

Are they just as bad as Anglias?Lack of care fitting flashings and (Redland 52) ,
just as bad, but bigger so the roof gets one quicker
It's more the lack of care or diligence fitting the tiles over some parts of the flashing. With a bit of careful trimming of the tile bottoms (where they sit on the flashing) you could improve those tiles instantly.
Trimming the tile bottoms is a great idea. As luck has it (maybe) just found some slightly smaller Marley tiles in my garden. I’m thinking they should be used between the two velux windows as the cut would be more like half a tile. They are slightly smaller in height, I’ve attached a photo. Do you think they might resolve that problem?

There is only really room for one Redlands tile between the two Velux windows. The left hand part of the tile points vertically so water can get in behind. The Marley tiles are not so wide meaning I could have one and a half tiles which would fill the gap nicely.
Yes I too would like to see pictures when finished.
