Window sill "drip gap" important?
Discussion
I don't think uPVC window cills work like that
The wooden one you posted has a drip routed into it about 10mm from the face and 25mm away from the wall....the reason being two fold.
Firstly if the drip was further forward the toe of the cill may rot off. Secondly if it was nearer the wall you 'might' get staining - more probable with timber windows
With uPVC cills the toe IS the drip...google upvc cill section
Granted they could be further out. I'd raise it with the intaller (presumably FENSA)
PS: you gangsta

Taking into accout Juless reply. The photos still make the cill position look wrong. Get the company back round to discuss.
Where the original frames thicker? This could be down to a lazy installer not wanting to make good the plasterwork inside! So he/they just pushed the new windows into the reveal until they met up with the plasterwork inside. If so you have a good case to make them refit them more forward.
This could be down to the companys surveyer/estimater.

This is 100% correct.They have fitted the new windows back to the inside plasterWhere the original frames thicker?

line. Windows should have been fitted further forward and plaster made good or
if not possible for some reason 180mm cills should have been fitted.

From memory im pretty sure the NHBC require a 40mm projection away from the main facing.

I'd say that was 100% the case hereWhere the original frames thicker? This could be down to a lazy installer not wanting to make good the plasterwork inside!

TBH looking at the pics again I'd be more worried the face of the windows are behind the rear face of the bricks..

Assuming standard English facing brick the window frame is at best positioned to achieve a minor overlap realistically I'd say only the mastic/backing rod is actually stopping wind driven rain from getting in between back of brick and front of window. TBH looking at the pics again I'd be more worried the face of the windows are behind the rear face of the bricks..
In a few years the gap will have opened enough for rain to directly penetrate the cavity.
