We have the experience EST. 1977 Worldwide Generator, Electrical & Mechanical Installation Contractors

1 Aidan Strain has been in business since 1977, initially as commercial, industrial and domestic electrical contractors working throughout the UK and Ireland. In 1993 an electrical wholesale outlet was established on the premises and remains a well known and established business serving local contractors, businesses and factories. In 1995 the range of contracting activities was broadened to include mechanical engineering as the business continued to expand in the UK and Europe. These individual enterprises were amalgamated to form ASEE Ltd. in 2000 and since then that company has maintained a considerable presence in the UK and Europe, both as generator installers and in delivering Mechanical and Electrical contracts which include:- Hospitals Telecommunications facilities Data centres Factories Water treatment plants Office and residential complexes Maintenance and building management services Minor building works

2 Worldwide Generator, Electrical and Mechanical Installation Contractors The company centres on a nucleus of 45 staff with additional resources employed as necessary to service particular project requirements many of which have peaked at around 160 personnel throughout the years. The engineering company has satellite offices in London and Germany, whilst still maintaining its head office base outside Newry, Northern Ireland. We recognise the importance of being adaptable to the needs of our clients. We are a privately owned company and our independent status means we are not part of a group or holding company that could restrict our participation. We have the experience
