I did allow access to my computer ( can't believe I was so stupid) , I've run virus checks and changed log on password, contacted bank, changed log on details on ipad and mobile. Can't think of anything else to do.

You should make sure that there is no obvious remote access software still installed on your computer (such as AnyDesk and Team Viewer amongst other names). Look down your list of programs for anything there which shouldn't be.
These are legitimate remote access programs so won't show up in a virus scan but may still leave a backdoor to your device.
The amount risk to you in the future will be in proportion to how long the scammers had access, what they had access to, what information you had stored on your device and so on.
