If you're thinking about raising a modification, please get in touch with us. Our experts can give you advice on your Proposal, explain how the modification process works and help to answer any questions you may have.


Once you've been in touch and are ready to write your Proposal paper, use the below form and send it to us by the monthly modification submission date which you can find on our Codes Calendar.


When we receive your Proposal, we'll check it through and work together to make sure it's easy to understand.
