Since finding in Norway that restaurants there sell non-alcoholic beers is normal and supermarkets sell a range of these drinks I have found that the UK is getting there. May be I just wasn't looking properly. I was surprised at how many beers were available from various supermarkets. My favorite is Bavaria 0.0% (larger) which is mainly sold in bottles but I have found Morrisons sell both bottle and can versions. Being a keen biker I attend many biker rallies and do a lot of camping and all campsites do not allow 'glass' so this is brilliant but the only company I have found which do this. Bavaria do a Bavaria 0.0% (Wit) which is nice too.

One thing to note is that a beer or wine can be classified as Alcohol Free if it contains 0.05% or less and De-alcoholised contains 0.5% or less.. So if you want no alcohol then make sure you read the label. Another benefit is the number of calories, for example Bavaria 0.0% (larger) contains 25 kcals (per 100ml)..
Now before someone asks "what's the point of alcohol free, it just isn't beer", there are many reasons why someone will not or cannot drink alcohol. With these products you can feel like you are part of a BBQ, party or social event and still be able to drive your friends home.
A useful source of information is The Alcohol Free Shop which has an extensive collection of wines, beers, stouts and Gluten free but check the prices.
