I used to work for a UK company and commuted from Belgium. I paid no tax in UK and very little in Belgium...
From the UK side of things I had to spend less than 90 days in the UK, at the time they didn't count the day that you commuted from Belgium and then flew off out of the UK as a day in UK as long as it all happened on the same day but that did change...
The rules from UK tax are quite specific and your family living in the UK is one of them (which is normal as someone said they will be using UK privileges so you have to pay for them...) although I don't know the agreements with India.
They even check things like Supermarket loyalty cards to make sure you're not in UK more than 90 days etc or when you say you are in India.
I had to keep prove of commuting, tickets, boarding cards etc in case I got checked which I didn't but know some that have.
Your best bet is to contact a company like MannTax in Onchan Isle Of Man they will be able to put you straight. (They specialise in Aircrew tax affairs amongst other things)
Good luck
