Wrong.

Confirmation that the work complies with Building Regulations. It's not
permission as they can't refuse to grant it provided the work is compliant.

Yes you can DIY it.

Without reference to Building Control you are allowed to *repair* an
existing window. As this is for a bathroom and I suspect the need is for
ventilation possibly the easiest way is to "repair" the window by replacing
one sealed unit with a replacement sealed unit with an extractor fan mounted
in it.
