  • Kier Northern have used the Engineering & Surveying expertise of SEP for over 25 years. They provide a professional, responsive, consistent and economic one-stop service. From pre-contract, site investigations and survey reports, to construction phase engineering and quality management, through to as-built information and CCTV surveys at completion. At our recently completed Wythenshawe Transport Interchange project SEP provided excellent support to both our bid and delivery teams.
    Graham Harwood-Senior Bid Manager, Kier Northern.
  • I have personally known and partnered with SEP for over 25 years, throughout which their client focussed service has always met my full expectations. Their Surveying expertise has aided Morgan Sindall during the bid stage of many projects, giving us the leading edge over our competition. And in addition, our Project teams have engaged their Site Engineers & Managers with great success, supporting the delivery of over 200 schemes during this time, projects ranging from £500k to £100m
    Frank Reynolds-Senior Bid Manager, Morgan Sindall Construction & Infrastructure
  • I have used SEP for over 10 years and have always found their Engineers & Surveyors to be reliable and experts in their field. I often recommend them to colleagues and other businesses.
    Jeff Boothroyd-Senior Operations Manager, Morgan Sindall Construction & Infrastructure
  • Finance is all paid off and it's all mine. Big thanks to Neil, Mike and Joe at SEP for their support both with providing a cracking instrument (& technical advice) and helping to arrange the finance. I always used to think of Spectra as the cut-price option but having worked with it for 12 months I prefer it to any Leica or Topcon I've previously used, particularly the laser scanning function and the Genlock.
    Alastair Banks -Banks Engineering & Management
  • Working with SEP from quotation stage through to delivery of their final report has always been handled in a highly professional manner with all timescales maintained as originally promised. They have a reputation in our consultancy practice as a company to whom we can entrust complex projects as they have a full understanding of the brief and are able to adapt to the specific needs of the project in a positive manner. SEP is, accordingly, our survey company of choice.
    Neville Shaw -Integra Consulting Engineers
  • We have worked with SEP for several years and they have become our survey company of choice. SEP’s attitude to projects and production of accurate drawings has always been professional and efficient and the team are a pleasure to work with.
