Sippdeal (er, YouInvest) charges here:http://www.youinvest.co.uk/Sipp/ChargesandRates/
Custody charge: holding above £20,000 -£25 per quarter
Fund Custody charge based upon the total value of funds in our funds universe...0.20% pa (maximum £50 per quarter)
So for a holding >100k, is effectively £300 pa if all your investments are funds, £100pa if none are funds. For me in middle, about £200pa.
Hargreaves Landsdown charges http://www.hl.co.uk/pensions/sipp/charges-and-interest-rates
Shares 0.45% pa, capped at £200pa
Funds, 0.45%pa on first 250k, 0.25% thereafter
So for a holding of 100k funds is £450pa, for £100k shares is £200pa.
On basis of charges, YouInvest wins. Of course other factors come into play also.
Any other experiences...?
