Replacing 100 year old single glazed windows? (edwardian)

I'm looking for advice for if these old single glazed windows should be replaced?

It's one of the last houses on the street with its original windows so right now it definitely stands out.

However, I do think it's important to make the house more energy efficient and increase the value as well.

Please can you help me figure out which of the following options would be best?


1) Secondary glazing + restore/paint the single glazed windows

2) Triple glazed flush casement windows (wood or uPVC available)

Current windows:

uPVC with astragal bars that are copying the original windows but do not look as nice imo:

A++ triple glazed flush casement windows:

There is a company making triple glazed windows with this little arch that kind of reminds me of the original windows. We could ask that the windows are shorter and then buy 4 more separate windows to fill the original squares at the top and we can add the astragal bars (but this would probably cost a fortune idk?

Thanks everyone :)
