How do I assess whether I’m being overcharged for tattoos?

e. g. I’m planning to get some words done, it’s two lines and about 5 cm across, and I got a quote for £100; doesn’t seem too expensive to me but I don’t know whether I’m being overcharged

i already have a couple tattoos but I got them during a time when an artist was doing an offer so I don’t think I can compare those prices

would appreciate anybody’s help thanks
