Legal Age Tattoo Uk

Advice about getting a tattoo done?
I am considering getting a tattoo done in the uk tomorrow.I am of legal age. What do i need to look out for? Iv found one place which seems to have good atrists http://www.skinflixtattooz.co.uk/
They seem to have decent standard of hygiene they have a steralization room and a big tattoo room. My worry is around the needles and stuff.
Not sure what too expect.
Do you think it would cost alot to have this tattoo done on my lower back?

Also another important question do they tattoo the outline and then fill in the color at a later date or is it all done there and then when getting a color tattoo done?.
I don’t know about the price, but I have a multicolored butterfly with 420 under it on the small of my back, and they did the whole thing on the same night. The outline took the longest, but the coloring in was quick, and I actually didn’t feel it. Mine was 180, but it depends on how much detail you want and how much labor/artistry your artist has to do.
