Hi all, I am looking for some advice.

I moved into my current property about a year ago. The previous
occupier was an old lady who got a grant to install a new combi boiler.
The boiler has been put in a 'pantry' in the kitchen, with the flue
passed through the top part of an old window, and around it filled with
plaster/morter.

My concern is that
a. the flue has insufficient support, and shouldn't be positioned
through a wooden window frame (this is 2m off the floor outside).
b. the flue is too close to an opening window in the kitchen (1.4m)

The paperwork received with the house included a building regs
compliance certificate issued by the company which installed the boiler
in 2005.

Can anyone please advise:
Whether the issues above are in compliance with current building regs,
and whether I am able to pursue this with Building control. Obviously
the last thing I would want is to draw it to the attention of the local
council, and then I am liable for getting it put right.

What do you think?
