It is a common worry but we have yet to meet an IT provider that is too difficult.  They’ll unlikely be happy but as the process is to simply introduce us as your new IT provider, we will handle the change-over on your behalf.  If you are thinking of leaving a provider than chances are they are used to others leaving too.  These kinds of providers expect a high churn of customers so just hands over the details.  Whatever happens, we will make sure you are looked after through the whole process.
