Opens

You can approach Barnett Waddingham yourself, and its key features say all UK residents are eligible with no nationality test. The catch is breadth rather than the door: apply without an adviser and you are held to a single portfolio with one discretionary manager from its panel.

FSCS £85,000 investment cover · apply direct or through an adviser

Account Terms The catch
Flexible SIPP
Annual fee
£295 a year plus £200 to set up without an adviser. A further £525 a year if you use more than one panel provider. All plus VAT
Dealing fee
Nothing from Barnett Waddingham; £25 per cash transfer to a provider off its panel
Can hold
Securities on the London Stock Exchange, AIM or any HMRC recognised overseas exchange, ETFs, funds, investment trusts, REITs, gilts, gold and commercial property. Without an adviser you are limited to one panel discretionary manager, which narrows this a lot in practice.
 Unlikely to suit below £50,000, or below £100,000 for the wider investment range. Work charged by the hour runs from £128 to £327 plus VAT.

US-UK tax treaty

The US-UK treaty stops most double taxation, but the saving clause lets the US tax its citizens almost as if it were not there. What survives the clause.
