Property developer and investment company Prospect GB has let 14,000 sq ft of office space at International House on Chester Business Park to the motor vehicle finance specialist.
The Funding Corporation initially sub-let International House from Scottish Power Manweb, which occupied the entire building from 2006.
The latest deal sees The Funding Corporation become Prospect's direct tenant after agreeing on a new 10 year lease for an undisclosed rent at the 25,900 sq ft detached office building.
International House serves as the headquarters of The Funding Corporation and the group's subsidiary companies.
The headquarters accommodates a national call centre, various administration departments, training suites and management offices.
David Challinor, managing director of The Funding Corporation, said: "International House is ideally suited to a multi-faceted organisation such as ours, and has adapted easily to our changing requirements over the past six years, during which the company has experienced record growth in the non-prime lending sector."
Prospect said suites from 5,575 sq ft to 11,754 sq ft are available on the soon to be refurbished 12,034 sq ft ground floor, and on-site parking facilities are available.
Chester Business Park is located approximately 1.5 miles south of Chester city centre. The park adjoins the A55, which provides direct access to the M53 and M56 motorways, and a regular bus service links the park with central Chester and Wrexham. Park occupiers include Marks & Spencer, Bank of America and Lloyds Banking Group.
Prospect was represented in the deal by sole letting agent Legat Owen.
