Re: Source of truly organic milk in UK (edit)
Possibly, but at least you can ask the farmers there. Then of course they may lie.
In truth, organic cows milk should be from grass fed beef that are left to graze all year round. The
Antibiotics etc are needed when cows are confined, and as far as I am aware all year round grazing doesn't happen in the UK, and when they are confined they are often fed grain, and other things they would not normally eat, even animal products.
As I understand it the injections are to counteract disease and digestion problems, caused by the artificial problems that we impose on these animals. Take a look at what John Robbins (from Baskin Robbins ice cream family), author of Healthy at 100 has to say about it (it's an anti dairy viewpoint)

Another reason I don't drink milk is because I am familiar with the work of Caldwell Esselstyn. I drink unsweetened organic soy milk with my tea. My reasons for not drinking milk are because I want to live a long healthy life rather than animal rights issues, and I am not trying to force that onto anyone else, each to their own.
But if you want organic milk, maybe you would need to find a farm that allows animals to graze all year round. There is only one person in the UK I know that has developed grass that can support grazing throughout the winter and that is Arthur Hollins, he died a few years ago sadly, but you'll find an interview with him here

I believe his family is carrying on his good work. I learned about him from the recent BBC documentary by Rebecca Hosking, called "a farm for the future". You can watch it on the BBCs website, or on Google videos.
If the farmers market doesn't get you results, try the nearest cattle market!
(edit)
In the John Robbins article, I noticed this text:
"It’s important to remember that grassfed is not the same as organic. Natural food stores often sell organic beef and dairy products that are hormone- and antibiotic- free. While these products come from animals who most likely were fed less grain than the industry norm, they typically still spent their last months (or in the case of dairy cows virtually their whole lives) in feedlots where they were fed grain. Even when the grain is raised organically, feeding large amounts of grain to a ruminant animal compromises the nutritional value of the resulting meat or dairy products and exacts an added toll on the environment."
I think the nearest you will get is hormone and
Antibiotic free milk, which you may well find at a farmers market. I have seen unpasteurized milk at mine, though haven't had cause to ask if it is hormone or
Antibiotic free.
