You can simple send os an email on email@example.com, if you have gotten a new company registration number and get it changed.
If the owner is the same, the current agreement just needs to updated. To do so we need:
New company registration number
The company name
If it is a new owner, we need to make a new agreement. To do so, send us an email, and we will send you a link so we can collect the information we need safely.
