Company History

A&L Mechanical Installations Ltd were incorporated in June 1990 and secured several small mechanical installation sub-contracts within the Water Industry.  Competitive pricing of enquiries continued leading to a steady stream of small sub-contracts awarded from leading Water Engineering Contractors. The focus of the business was to provide Mechanical Installations within the Water Industry and to  establish a Client Base by providing Quality, Service & Value.

Excellent progress was made within 5 years as the client base developed and became more established. By 1995, the Business began to gain recognition within the Water Sector. Growth of the business continued between 1995 & 1999, A&L developed a strong reputation for delivering consistent Quality and Service. This led to new opportunities in Scotland which led to several new clients and contracts.

With a growing client base and continued investment, A&L continued to develop and secure contracts within the Water Industry. Since 2005, A&L have concentrated on Scottish Water’s Capital Investment Programmes and the Company is a well-known and  established Framework Contractor and Delivery Partner. Consistent provision of engineering solutions and installations has led to year-on-year growth and Frameworks have been secured throughout Scotland.

In recent years the business has continued to develop and improve. In 2018 a revised business strategy was developed to include restructuring, re-branding, and wider marketing. The company acquired larger premises and invested heavily in growth and development of the business. A concentrated effort to widen the exposure of the business throughout the UK and Ireland has been very successful leading to Award-winning recognition, accreditation, and enhancement of the company’s reputation throughout the Water Industry.

Future Years

Business is about Growth, A&L is about growth. There is an established positive and ambitious nature within the business and a strong track record with key Blue-Chip clients in the Water Industry. Taking this and the continued investment in this sector into account, there are many opportunities available.

We consider the Business to be a highly successful organization that will continue to learn and develop. It is the intention to continue to strive for excellence, to make the most of opportunities arising and to continue to be a success. We are rightly proud and protective of our reputation which has been achieved by the continued dedication and hard work of all employees for over 30 years.

To offset our carbon footprint, A&L plant a tree for every contract awarded.
