About Us

For over 25 years SEP has been supplying Engineering and Surveying Services to clients across the UK and Overseas. During this time we have grown steadily to become one of the largest independent companies in our field.

Our head office in Skelmersdale controls over 80 site based staff who are currently working on projects for Major Petrochemical Companies, Utilities Companies, Property Developers, Building & Civil Engineering Contractors, Local Councils, County Councils, Architects and Private Individuals. These site staff are complemented by our in house computing team that produce CAD drawings, calculate earthworks volumes and provide health and safety services and technical support for both our clients and SEP staff.

The broad range of services that we offer are highlighted on the rest of this website but if there is a particular requirement that is not shown then just give us a call and we will be happy to provide a solution to your needs.
