Auto escalation means an automatic increase of sum insured. In Bharat Griha Raksha policy there is an automatic increase (escalation) of 10% on base sum insured every year.
For example: If the initial sum insured = 1,00,00,000 then,
2nd year sum insured = 10% of base sum insured 1,00,00,000 + 10,00,000 = 1,10,00,000. Every year, the sum insured will increase proportionally.
