Are there any English speaking flight schools to get a PPL in continental Europe?
Some years ago there were a couple of flight schools on Malta, I'm not sure if they are still operating, DuckDuckGo could probably tell you

The most common way of getting a JAR (pre-EASA) PPL (for UK trainees) outside the UK used to be to go to a JAR accredited school in the USA. Florida was very popular.  I expect there are schools in the US that are allowed to train to the EASA syllabus these days.  I think you need to travel on a training visa to do this and I'm not sure what is involved in getting one

I think I'm right in saying your flight test can be taken by an EASA examiner anywhere, no need to come home to do it (and anyway you'd want to do it over familiar territory)

A big warning to anyone learning to fly is not to pay upfront.  Pay lesson by lesson.  Flying schools can go bust very quickly, many students have lost a lot of money this way 

Personally, I would be wary of training outside the UK, the weather conditions and procedures will be very different from what you are used to, and a low-hours pilot could easily get caught out.  Marginal conditions can go bad on you very quickly.  If you do do this, try to get some supplementary lessons in poorish weather and get some time fly through UK CAS to get used to ATC procedures
