Stephen Parker started as a domestic plumber 30 years ago. Parker PHS still caters for domestic clients in the East Lancashire and West Yorkshire area, but the vast majority of work undertaken is as a commercial plumbing contractor. Refurbishment and maintenance of existing plumbing and heating systems are another service that the company offers. A dedicated after care team is always on hand to ensure that any newly installed systems run smoothly following hand over at project completion. Heating and mechanical systems, traditional and renewable energy, are designed and installed by the company.
