Here’s an overview of the types of malting barley grown around the world:
“As far as barley suitable for malting is concerned, it can be stated that all the varieties grown in the British Isles are two-rowed; two-rowed barleys are also grown in Australia, Ouchak and Chile, while six-rowed varieties are grown in California, Australia, Morocco, Smyrna and Chile, as well as in some other countries. Prior to the 1939 war considerable quantities of foreign six-rowed barleys were used by British brewers, mainly from California and Chile, as well as some Chilean two-rowed. Due to the sunnier and more equable climates of these countries as compared with the British climate these barleys were more uniform in quality and this was of distinct advantage to the maltster. Further, the coarser husk of the six-rowed varieties tended to give a better filtration in the mash tun and to prevent those filtration troubles caused by the too-close packing of the undissolved parts of the malt (known to the brewer as grains'), which form the medium through which the solution containing the extractable materials is filtered off. In fact most brewers used from 30% upwards of Californian or other similar foreign malt and many brewers considered that they could not brew satisfactorily without them. However, experience dining and since the war has shown that present-day beers can be satisfactorily brewed from all British malt.”
"Brewing Theory and Practice" by E. J. Jeffery, 1956, page 129.
British brewers had this thing about Californian malt and got most upset when it was unobtainable during the two world wars. But the last one seems to have weaned them off it.
He’s right in saying loads of six-row barley was imported before WW II. That’s very clear from brewing records. Britain at the time produced way too little barley for its own needs. But that all changed during WW II, when there was a massive increase in barley production. As this table shows:

This can’t have all been barley for brewing. Slightly less beer was brewed in 1954 than 1938, while the total amount of barley both home grown and imported had grown significantly, from just under 38 million quarters to 63.5 million.
It’s clear from this next table that only a small percentage of barley was used in brewing:

“At the time of revision (1956) increasing quantities of Australian Cape barley (6 rowed) are coming into the country again, but even so, beer in Britain is still brewed mainly from malts made from barleys grown in Britain.”
"Brewing Theory and Practice" by E. J. Jeffery, 1956, page 129.
You can see in the table that barley imports had risen from zero in the final war years to about their pre-war level by the mid-1950’s. But I don’t see foreign barley mentioned in brewing records.
Taking Whitbread as an example, in 1938 all their Ales contained malt made from Californian barley. About a third of malt in the case of Bitter and IPA, 15% for Mild. While their Porter and Stout had about 5% malt from Ouchak barley from Turkey. In 1954, when barley imports were at pre-war levels, there’s no foreign barley in any of their beers.*
After WW II British beer was being brewed mostly from British ingredients for the first time since the mid-19th century. Until the British hop industry collapsed in the 1980’s.
