Frequently Asked Questions

Q: Who are Advanced Engineering Solutions Ltd?

AESL was set up by a number of senior managers who were formally employed by British Gas at their Engineering Research Station at Newcastle Upon Tyne. The company was formed in October 1995 following the closure of the research establishment. The founding members realised that there was a market for their skills and knowledge within a privatised and competitive energy market.

The company was originally based at Sunderland in small offices on a business park. However due to rapid expansion it was necessary to find larger and more appropriate premises, moving to Cramlington in 2000.

The founding directors have well over 100 years of experience between them related to all aspects of gas engineering, pipeline materials and equipment. The company originally offered consulting services but soon saw the opportunity to provide pipeline condition assessment and asset management services both within the gas and water sectors. The company has developed its own pipeline inspection equipment and related condition assessment and life prediction techniques based on a statistical modelling. The company is rapidly becoming recognised as one of the leading companies in this field.
