The Trelco Story

Trelco Plumbing has built its reputation on trust, reliability, and consistently high standards of workmanship. Much of our work comes through word of mouth and long-standing customer relationships, something we take great pride in.

Founded by James Trelawny, Trelco is rooted in a straightforward approach: do the job properly, be honest with customers, and stand by the quality of the work. That commitment has shaped the business from the outset and continues to underpin everything we do today.
