On a par with Euros, ironically enough (and soon with the Dollar).
But, seriously, there really are no such thing as 'British values'. We're a mishmash of different cultures, religions, and ethnic groups. What are sometimes characterised as 'British values' are basically either just common decency, which exists independently of nations, or an air of self-deprecation, usually masking an underlying belief in innate superiority (more of an English than a British trait). As Flanders & Swann put it:
'The English are moral, the English are good
And clever and modest and misunderstood!'
Though Donald Swann was hardly a stereotypical Englishman:

'Donald Swann was born in Llanelli, Carmarthenshire, Wales. His father, Herbert Alfredovich Swann, was a Russian doctor of English descent, from the expatriate community that started out as the Muscovy Company. His mother, Naguimé Sultán Swann (born Piszóva), was a Turkmen-Russian nurse from Ashgabat, now part of Turkmenistan. They were refugees from the Russian Revolution.'
