I presume that your cucumbers are indoors, so...

If it wasn't an all-female variety, the bitterness may have been caused by pollination by male flowers

If there are any other varieties in there too, they may have cross pollinated

What do you think?

Oh, I also found this on a website which may be of interest...

Some reasons for cucumbers to turn bitter:

many varieties which are not totally seedless will set male flowers caused by water or heat stress. These male flowers can pollinate the female flowers.

seedless varieties pollinated by bees visiting the greenhouse.

air pollution, excessive carbon dioxide or pesticide sprays.

high salt levels in the growing medium.

When you say they were from Sainsbury, were they saved from a cucumber you bought?

If they were bought as seeds, I think CuteC has covered it all.

Good point - not all varieties will come true.
