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.

SEP continues to grow and is now a Trimble Authorised Service Partner for the Spectra and Nikon product lines. As such we are able to offer a full range of optical, GNSS and laser survey instrument solutions along with the SECO range of survey and construction accessories. The broad range of products we are able to offer are included on this website, please feel free to contact us if you have a specific requirement that you wish to discuss.
