You could try a Fidelity Fundsnetork JISA purchased via Cavendish online - £25 one off fee - they then return all initial commission and all the trial commission they could have received eg 0.5% as opposed to H-Ls 0.25% (which by the way H-L do not pay for JISAs).
You do however pay for fund switches of 0.25% under FN whereas H-L is free. However, if you're holding for the long term and are not swtiching often then Cavendish will I think almost certainly be better than H-L on cost grounds.
Cavendish are execution only so you get nothing else from them - eg no ratings, no account reports etc etc
With regard to RDR - it is my understanding having done some digging about that for execution only brokers there is basically no change - they will continue to be able to extract trail commission and rebate (or not). Which is why there has been a sudden explosion of fund platforms. The warning here is to avoid getting trapped (ref H-L £25/fund transfer fee), albeit I also believe RDR is suppose to be looking at platform reregistration/transfer aspects as well. On this basis FN looks a reasonable bet given virtually ever broker currently services them which means a simple reregistration rather than transfer (eg sell/rebuy).
As an aside it might be worth noting that FN support sub-accounts -eg one for ISA, one for OEICs, ones for designated accounts etc etc and each can be given a different a agency (I know this as I'm doing it at the moment)..
CoFunds does not support this model so everything has to be with one agency.
