Insurance question.

[oakdale]

I was involved in a no fault accident in May 2016 and dealt directly with the other parties insurance but I of course informed my insurance about it.

It's just dawned on me that I didn't tell the OH's insurance about this, I'm a named driver but don't drive hers very often.

What are the implications of retrospectively informing them of the accident, (I know it may put the cost up a bit) but I'm more concerned they may take a dim view of not being told at renewal?

I'm insured with Aviva and hers is with Quote me happy (the same company) so they'll probably know already I but haven't formally informed them.
