Question about getting a country visa

My parents and I are Indians. I had been holding a passport coming from the country when I was a kid, and I am currently holding a passport from the United Kingdom. I need to request for a multiple entry visa that I can use for five years. I just want to visit my father who is now working in Chennai, India. How can I acquire the type of visa that I need here in the UK, and how much do I need to pay?

I suggest that you call the Embassy of India so you would be aware of the details you need to know about obtaining of it.
