Is it possible to buy add-on covers that the insured didn’t buy initially with the policy?

Yes! You can buy add-ons that you didn’t initially buy with your policy. The best time to do this is when you renew your plan – you can simply choose the add-ons you want and pay the revised premium. You can also include add-ons mid-way through your policy tenure through a process known as an endorsement – however, you would have to contact the customer care representative of the insurance company for guidance.
