£700 seems steep to me for setting up an ISA, especillay as they have advised on the more complicated area of pensions for just £500. are there any other advisers who you could contact in your area? Did they take their fees from the pension ( they should have as 20% or 40%, depending on your tax band, will have been paid by the governmant though tax relief).
As maxstream said you can go direct but will pay 5% initial fees. There are some market leading companies which will pay commission to your IFA and still get 100% allocation rate (2.25% commision). Sterling, who are part of the Zurich Group, offer this and I see these regulary used by the IFAs I work with.
What was your risk profile? This is important as a portfolio planning tool can be used to build a portfolio of funds to match the required asset allocation for your personal risk profile. There are plenty of other companies such as Fidelity which will also offfer this but I would go back to your IFA and ask whether he would be willing to negotiate on their fees.
I could not disagree more with Maxstream when he says that reading a magazine is better than getting advice, although it would be cheaper. You get what you pay for at the end of the day and if this is important to you you should seek advice as the returns you get are mostly determined by the diversifitacion of your fund choice.
Good luck.
