North Energy Associates Ltd was formally incorporated in October 1991 with offices at Morpeth, Northumberland. As a commercial consultancy company, its original aim was to assist energy efficiency improvements and renewable energy developments in the North East of England. Since that time, the work of the company and its dedicated staff increased dramatically to encompass sustainable energy development, in general, and global climate change mitigation, in particular.

An expanding range of clients included private companies, local authorities, government departments, national agencies and international organisations. Additionally, the geographical scope of the company’s activities widened to embrace all parts of the United Kingdom and many Member States of the European Union as well as countries as diverse as Algeria, Brazil, China, Egypt, Morocco, South Africa, Syria and Turkey. Professional expertise was provided in numerous areas, especially identification of energy saving opportunities, implementation of biomass heating schemes, planning for wind power developments and life cycle assessment as a means of measuring reductions in greenhouse gas emissions. The increase in activity and the staff team was matched by, first, a move to new offices in Stocksfield, Northumberland, and, then, the opening of an office in Sheffield, South Yorkshire.

After operating successfully for more than a quarter of a century, the company undertook voluntary and solvent liquidation in 2019, due to staff retirement and changes in career paths. The Directors would like to thank all members of staff who worked so enthusiastically and conscientiously over the years, all our partners, many of whom have become close colleagues, and all our clients, many of whom have had long-term productive relationships with the company. The enduring contribution and reputation of the company is a lasting testimony to the commitments and goodwill of every one of those involved in this worthwhile and stimulating enterprise.

Commercial activities of the company ceased at the end of October 2019.  This website will be maintained for some time to provide contact details for Nigel Mortimer.
