First direct account switch

I’m considering switching my spare (Natwest) account to first direct to take advantage of the £125 bonus and paired 5% savings account.

Now my question is, does anyone have experience of doing this? My NatWest account holds no money, nor does it have any incoming or outgoing payments, DD’s or standing orders.

Would I still qualify for the welcome bonus?

Iirc First Direct have a minimum monthly deposit amount otherwise there’s a charge.

£1000 monthly deposit. I get paid weekly which is a royal PITA so I plan to get paid into that and then pay my Monzo normally on a fixed date.
