As per title, last winter I put cheap bubble wrap all over my windows,
and it worked. The temperature inside raised a couple of degrees, which
was just enough to go from absolute freezing to having to turn the
heating on only a couple of hours a day, vs on the whole day.

The temperature now in about 20 degrees inside during the day and 17 at
night (if the weather keeps this way).

Should I take the bubble wrap off or leave it on?

If the temperature goes up, I can just open the windows.

Would bubble wrap also protect against excessive heat or make it worse
in summer?

It'll make it worse. Polythene is said to be transparent to infrared, so
the heating effect of the sun's rays will not be stopped by it. The
rooms will get hotter. Also, cheap bubble wrap is very unlikely to have
any UV stabiliser included, so after a few years at most will start to
disintegrate. It is best to remove it over summer and put it back for
winter..

Do what everybody else does. In peak summer heat draw the curtains and
close the windows

When I used to use it for insulating a greenhouse, it was usually
brittle by the time I came to take it down next spring.

Rubbish.

The curtains stop solar gains and the closed windows stop hot outside air.
By doing this butopening windows at night, I can keep indoor temps down
to about 25-27°C even on 30°C days

Those are walking around the house naked temperatures for me. Less
clothes washing to do as well.
