Give Fusco builders a call on Monday. One of the brothers is a plumber, but I'm not 100% sure he does anything outside of their own developments. If you don't have any luck talking to them I know one of them (mrs business partner) and can ask, if you prefer me to ask let me know because I'll see him tonight when I pick the mrs up from work.
Dave I reckon it looks great, just need 215 on the front or 225 all round.
