About Thornton & Lowe:

Thornton & Lowe is an independent consultancy that helps organisations win and deliver more public sector and regulated work. We support clients across the full procurement lifecycle, from early opportunity identification and bid strategy through to tender delivery, framework applications, evaluation support, and wider commercial consultancy.

Known for our practical, hands‑on approach, we work closely with clients to understand their goals, provide clear and commercially focused advice, and deliver support that is both compliant and results driven. Our team combines deep sector knowledge with a collaborative, values‑led culture, creating an environment where people are trusted to make a difference, contribute ideas, and play an active role in helping clients succeed.

As the Client Support Executive (CSE), you will work within the business development team and support our clients from the point of handover, coordinating their kick off meetings and having regular contact with them through the delivery process and post submission. The CSE will also support several of our retained clients and work alongside our Key Account Manager, sales team and bid professionals to deliver the service to our clients that Thornton & Lowe are known for.
