Thanks for the feedback. I probably should have been clearer with my question. Rethinking, I suppose I was most interested in ownership issues and tax implications. The money is mine and therefore putting it in an account for my children am I likely to have issues "reclaiming" it back from them (they are both under 4)? I'm not intending to place it there long term.

I have slowly tried to lower my currency exposure. It's been a frustrating ride in this respect and I'm all too aware of the direction of the exchange rate in recent and more historical years. Perhaps I should just exchange the GBP as soon as I receive it in future. Only over time has it become clearer and clearer I won't be leaving Switzerland in my lifetime.

If anyone has an alternative investment that they would like to recommend I welcome suggestions. The core aim of this particular investment was protection of principle and low risk with any upside. Instant access with a time horizon of perhaps less than a year. I do already hold equity and fixed income ETF's and would be open to suggestions in this area if it fits those requirements.
