I'm building a widebeam narrowboat and I needed help with some odd fitting drains for the sink and shower. These guys were so helpful and found exactly what I needed for the job. They also gave me good advise on future proofing and doing the job right. I spent so much time going to all the DIY shops and getting so frustrated. I should have come here first and I'll definitely return for any future projects and save myself the headache. Thanks again for your help. I really appreciate it!
Response from the owner:Allan Thank you for your kind feedback. Our team is here to help, but we are always grateful to hear that we are doing a good job. We hope you get to enjoy your new narrowboat soon.

After trying all the local main trade places for an oversized undersink overflow without success, I stumbled across JHPS. What a relief! Their Google description is totally accurate. The chap who served me was experienced, helpful and got me the part I needed. Wish I'd googled days earlier. Fantastic products and service. Definitely recommend them.
Response from the owner:Thank you for your 5-star review. We pride ourselves on our service so it is always great to here back from customers. We are also glad everything is sorted in regards to the overflow.
