Yeah, if you're in the UK, just go with a local printer. Here's some UK ones:
http://comicprintinguk.com/ - Rich is great and does work for loads of UK small pressers, so I'd definitely recommend him.
But in the past I've also printed with Inky Little Fingers and they were also ok (though maybe not as helpful for beginners!)
I've also heard https://mixam.co.uk/ is quite good for value, though I have yet to try them.
