On 1 June 2001 Middlesbrough Council entered into a Strategic Partnership agreement with HBS Business Services Group Ltd.

As part of this agreement the administrative staff and the administration function of the Teesside Pension Fund transferred to HBS, however the overall responsibility for the administration of the Fund remains with Middlesbrough Council.

Mouchel PLC acquired HBS in the Summer of 2007 and subsequently, in late Spring 2015, this business was acquired by the Kier Group PLC. In November 2018 Keir Pensions became apart of the XPS Pensions Group

Many of the original staff continue to work for the company to provide you with hopefully, what you consider to be an excellent service.

The Pensions Governance and Investments function remains under the direct control of Middlesbrough Council.
