It appears there is input list limit of 100 NGRs. I have 2,405 NGRs to convert to postcode. Is there a quicker and easier (free) tool that will do the job?

Philip, try https://www.royalmail.com/find-a-postcode. Input the address without the postcode and let that page tell you what it is.

I found the exact grid reference for our property and entered it.The post code then came up which is the post code we already have,however this postcode is assigned to a property some 900mtrs away and is not on the same road as ours.I need a pinpoint postcode for our property.Can you help me?

My earlier (below) comment was wrong. All post codes were in accurate order but there was some stuttering from 2-6 times on occasions. Removing these stuttered duplicates gave me a complete and accurate list, which could be pasted.

Excellent if you have a list of different grid refs to convert to post code, but any known duplicates listed apart in the grid ref list, are listed together in the postcode list, which knocks the list out of sequence, and needs then manual sorting. Otherwise it's Brilliant
