Testimonials

Take a look at what customers say about HJN Plumbing

David M
Residential customer

I had a complicated leak that two other plumbers couldn't find. Harry identified the issue within 20 minutes and had it fixed the same afternoon. Honest pricing and a very professional attitude. I wouldn’t go anywhere else

Sarah W
N7

I’ve used Harry for years. He recently handled a 1st and 2nd fix for our bathroom renovation. He’s one of the few tradesmen who actually shows up when he says he will and leaves the place spotless. A real expert who knows his stuff.

Arjun P

Called Harry out for a toilet that had been leaking for weeks. He was round the same day, identified the fault immediately, and had it repaired in no time. No mess, no fuss, and a very fair price. It’s rare to find a plumber this reliable and skilled. Fantastic service
