Stocks and Shares ISA - Clean funds and charges

Froggitt

All comments and opinions welcomed. Objective - looking to reduce charges and commissions, as I'm sure its higher than it could be.

Current - its a bit fragmented, so I want to tidy up, and save some money in charges.

• Corporate ISA with Share Centre, value £20k, charges 0.5% pa
• 6 funds with Hargreaves Lansdowne - Schroder, Artemis, Blackrock - each worth say £3k
• 1 Fidelity fund with Cavendish, worth £6k
• L&G FTSE tracker - not sure who gets the trail on that - £15k
• Henderson smaller companies tracker - £15k

As far as Im aware, all in dirty class funds.

Thoughts - start with moving the Share Centre Corp ISA, costing £100pa, to a Share Centre Self select ISA, £4pm, ie £50pa.

• Transfer all the Hargreaves Landsdowne funds in species, to Share Centre, who will pay the HL switching fees, which would be £180 or so?
• Share Centre then switch to clean funds at the next XD date, reducing the AMC by say average of 0.5% (£100pa). No platform fee to pay. All admin costs covered by the above £4pm Self Select ISA fees.
• Then transfer the Cavendish, L&G and Henderson funds to Share Centre also, and await the cleaning and saving (£150pa).

Does this all sound sensible? Have I understood the costs fully? Does anyone have a better alternative suggestion? I don't do much buying or selling. It appears I will be making circa £300pa in charges savings.
