31SJP Investments Limited.

UK company. Companies House number 07436194. filing history.

Nat Rothschild was appointed director on 5 February 2026. That is four months before this archive (6 June 2026).

The address

Registered office on Companies House:

c/o Nr Private Office Limited, PO Box 622, La Fleche House, 8 Berthelot Street, St Peter Port, Guernsey, GY1 4LX.

“Nr Private Office” is a Guernsey services entity. The initials “Nr” track to Nat Rothschild’s personal office structure on other filings.

The name

“31SJP” reads as 31 St James’s Place, London SW1A 1NR.

That is the historical address of the Rothschild family’s private office.

Spencer House (the Rothschild London base) and the family Trust offices are clustered on St James’s Place.

The corporate name is therefore a direct reference to the London family-office address.

Why it matters

This is the most recent UK directorship Nat Rothschild has taken — just four months old as of this archive date.

The structure is: UK-incorporated company, controlled through a Guernsey “Nr Private Office” address.

The full filing history, articles of association, PSC declaration, and first-year accounts are pending.
