I'm not sure what region the Indian Wii's are. I'll look into it for you, but as it's in Asia, I'd say that the Indian Wiis are NTSC-J. UK games are PAL region, and PAL games only work with PAL consoles.
Like I said, I'll look into this for you.
EDIT: I found this diagram which outlines console regions.
India and the UK are different regions, and the Nintendo Wii is region locked. Only games from the same region as your Nintendo Wii will play on it. So, if you bought an American Wii (NTSC) then you can only play NTSC games.
http://en.wikipedia.org/wiki/PAL_region <-----This link shows all the countries within PAL regions. Unfortunately, India isn't one of them. That means that UK games will not play on an Indian Wii.
My advice would be to look on the box that your Wii came in, and check what region it is. You will then have to buy games from that region for it. If it's NTSC-J, then I reccommend buying Japanese games from www.play-asia.com. If not, sell it and buy a UK Wii (PAL region).
