The "offline" course prices are here. It seems like the roughly equivalent MSc degree offline would be £15.5K for home and EU students and £33,250 for overseas students. You would have to add to that living expenses which are considerable in London (perhaps another £20K) https://www.imperial.ac.uk/students/fees-and-funding/tuition...

I did an MSc in Computer Science at Imperial (long before online courses existed) and it was by far the hardest academic thing I have ever done. Imperial is academically excellent, and likely the best university for science subjects in the UK and perhaps top 5 in the world. Having said that I'm sure much of the value is from being there with other students and teachers, and I don't know how much of that you're getting from an online course.
