There are none that have zero % annual fees for looking after your investment, as far as I know. There are some which have no ditionalfees over and above what the underlying Unit trusts or Investment Trusts are charging (which is already non-zero).
Since there is very little extra work to do (tax reclamation on dividends having bit the dust) I don't see any reason to pay an =extraannual fee for investing via an ISA wrapper, and most places agree with me.
The underlying fee covers all the investment 'looking after', in terms of where to put the money. This ranges from ~0.5% for simply tracking an index up to several% for aggressive ITs which have performance linked management fees (i.e. is they beat the index, their cut goes up).
And you're wrong, you don't get what you pays for anymore. You get =at best= what you pays for. Most places these days you have to kick and scream to do even half that well (he says, sitting here waiting for an 'overnight delivery' shipment via AMTRAK [Telford] which should have been here yesterday).
