Fees for OCI by Postal Order

[nnj10]

We are a family of three (2A + 1Ch) and have already obtained our surrender certificates for Indian passport and planning to apply for OCI by post.

The postal application fees can only be paid by postal orders according to HCI London Website.
Does this mean each of us need to send separate postal order, given that fees are £175 per head, and maximum value of postal order is £250?

Also, can all three application be sent in one Royal Mail Special Delivery Envelope as a family application?

[ban.s]

either £175 x 3 or £250 x 2 + £25

all documents in a single envelope

[Seedy]

either £175 x 3 or £250 x 2 + £25

all documents in a single envelope

to avoid confusion send 3 x £175 all in one envelope. Write the GBR.. no., name and address at the back of the postal orders.

Thanks.

Gone for 3 x £175.
