About Us

With nearly a century of industry experience, WJ Shirley has developed a proven strategy for delivering high-quality commercial drainage solutions while providing exceptional value to our clients.

Our commercial drainage services are specifically tailored to the real estate sector, offering independent drainage consultancy and contracting services to leading Building Consultancies, Investors, Fund Managers and asset managers. We understand the technical, financial and compliance pressures associated with commercial property and structure our services accordingly.

A Consultancy Approach That Sets Us Apart

Unlike other drainage consultants, WJ Shirley produces its own unique reporting methodology. Our drainage reports have been refined to deliver a clear, comprehensive and commercially focused analysis of each drainage system, including condition, risk, cost implications and actionable recommendations.

Every report is prepared by an experienced drainage consultant, presented in an easy-to-understand format designed for property professionals. Clients consistently find our reports clearer and more insightful than standard industry reporting platforms, including traditional Wincan outputs.

Uniquely, our reports also incorporate environmental risk and legal compliance assessments. These critical factors are often overlooked, yet they can lead to irreversible environmental impact, significant financial exposure and reputational damage if not identified early.

We are committed to providing honest, realistic and commercially grounded advice, always acting in the best interests of our clients and their assets.

Health, Safety & Industry Compliance

WJ Shirley places Health & Safety at the core of all operations. Our drainage engineers are CSCS qualified and first-aid trained, and all equipment is regularly inspected and serviced to ensure compliance with industry standards and best practice. This commitment underpins our exemplary safety record and reliable service delivery.
