Hi
As the title says, Marmalade car insurance: dc recently passed their driving test, aged 19.
Looking around online for insurance for dc to drive our family car, by far the cheapest option was Marmalade pay as you go, and the most suitable because dc is away at uni mostly so wouldn't want to drive our car all that often. (dc wont have their own car for a while yet)

I contacted our main insurer, Aviva to check that it wouldn't invalidate our existing insurance or whatever: I got different answers on Twitter dm and when I phoned the call centre 
one said it's up to us yeah it's fine, the other said no it would make our vehicle 'double insured' which is wrong apparently - but the insurance would be specific to our dc, not our car?? And of course if we made a claim, it would only be on one of the policies, depending who was driving
Totally confused
Has anyone used this Marmalade pay as you go insurance for a new driver? Is it legit? Will it invalidate our existing car insurance?
(Im thinking it must be legit/legal because they've been in business a fair few years, I guess Aviva are told to upsell as much as possible!)
