Viva not all of them will charge but yes that's what you would have to pay if needed.
Anyway I emailed Merula and asked them about this. Is a small charge but it's better than a ridiculous £100 migration fee.
Quote from email. Removed name as not sure I can post it.
There is normally a £15 charge for these migrates as long as no BT engineer visit is needed for the migration. We can waive this if there is a new 12 month contract with the move.
BTW viva I did look at your fibre but ruled you out, as your fibre prices cost to much. Free Fibre connection may of helped.
