If you need to make any changes to your site details, there are a number of things you can do.
You can complete an Amendment / Cancellation Form for the plot you need to amend by filling in all of the applicable fields. If you need to make alterations to more than one plot, you will need to submit a separate form for each.
Alternatively, if you registered your site online, simply log into your Robust Details account and amend your site details online.
If you’ve lost the original paperwork, you will need to write to your Building Control Body and inform them that you wish to amend your site details and what you intend on changing. Robust Details Limited also ask that you send them a copy of the letter along with your cancellation form.
