Isa time.... where did yours go?

No new IFISAs for me for some time now. Down to about 5% in total capital of my all time high in P2P and drawing done the last accounts and/or waiting for administrations to be completed.

My final XIRR for the 2017 onwards foray into IFISAs is currently around 5.5% after losses, and would drop to just under 5% if all remaining capital is written off. Much of it likely will be, so let's say I got 5%. When I started, I'd hoped for about 7%, so it has done less well than that. It has certainly done less well than if I'd kept it in equity, or an equity/bond mixture. It has done better than cash. Looking back, I over allocated to P2P, attracted by the tax advantages (as a higher rate payer); perhaps now I am under allocating, but I don't think the risk reward at current interest rates is attractive. I'm getting 5% risk-free at the moment.

My highest real world returns (for IFISAs, so excluding non-ISA P2P) were for Moneything (I got out in time), Landlord Invest and Proplend, all of whom exceeded 7% XIRR after losses. ABLrate will also creep in to that list if more than about 20% of the outstanding capital is repaid in the two loans I have left there (again, I got out in time with massive discounting in the SM, a great decision in retrospect, even though I gave up 2%+ of my XIRR to do so). Honorable mentions for HNWLending and Crowd2Fund, who achieved a tad under 7% after losses.
In terms of absolute monetary returns, HNWLending, Proplend, ABLrate and Landlord Invest win (in that order), as I had the largest allocations there and they lasted the longest. Moneything had a high XIRR, but I didn't have much there and it folded fairly quickly. 

Anyway, all has been going into S&S ISAs for the last few years, but I am trying to diversify as much as possible away from pure equity. 
So increasing exposure to Managed Futures, Trend, Commodities, Gold, etc. A little bit of leverage via capital efficient funds (eg Wisdom Tree WTEF/NTSX). And a tiny dabble in crypto via etfs. Just in case.

The CGT reduction is quite a big deal longer term. I'd always assumed I could get by on harvesting £12,000 per year CGT relief, but £3,000 pa is effectively going to tax all significant gains (with no indexation for inflation). So the next few years will also be focussing on a lot of Bed'n'ISA work I think. 

Good luck everyone! 

EDIT: and to answer the question directly, my ISA went into Interactive Brokers, and the family ISAs went into Interactive Investor (via the Friends and Family scheme), Trading 212, and (for LISAs) Dodl (via AJ Bell). Remember you can split your ISAs across providers this year too!

WW3 is not in full swing yet.

Same as acrued interest in P2P.
