Shepley Engineers

Shepley Engineers Limited is based in Cumbria, operating as a major multi-discipline contractor and project manager. We specialise in term contract works within the nuclear and chemical process plant sectors. The Shepley Group provides a self-delivery solution covering supply, high integrity ME and I manufacture, installation and commissioning support. We have two wholly owned subsidiaries:

  • PPS Electrical – an electrical and instrumentation installation specialist
  • West Cumberland Engineering (WCEL) – A class 1A fabricator and precision parts machinist

We are engaged in a number of capacities from main contractor to sub-contractor and, in some instances, as advisor and consultant. We work individually or in collaboration with complimentary service providers or partners (e.g. as part of Cumbria Nuclear Solutions (CNSL)) and a significant proportion of our current workload is delivered via long term framework agreements. It has been necessary to develop our processes, systems and culture to be effective and responsive, which has allowed us meet the evolving standards and requirements of the client at the Sellafield site since 1948.

Mechanical & Electrical Supply and Installation

Shepley Engineers has a large pool of skilled trade resources and a very healthy training and development agenda with a large domestic apprenticeship scheme. We have a proven track record of safe and effective ME&I installation delivery across a range of projects and environments.

Our work in this area includes routine maintenance as well as major outage work and asset enhancement. We are able to self-deliver the key disciplines in the areas of Mechanical, Electrical and HVAC as well as minor Building and Civil work.

Nuclear Engineering & Decommissioning

The Shepley decommissioning teams offer a unique blend of practical conventional decommissioning experience together with a safe and proven track record involving the introduction of new and innovative technologies where appropriate. We offer a cradle to grave service across a range of small, medium and very large complex nuclear decommissioning problems, mainly as part of CNSL. Manufacture In WCEL we have well established and experienced fabrication and precision machining capability focused on the manufacture of high quality products including process pipework, tanks, vessels, modules, waste containers, glove boxes and high integrity ductwork mainly for the nuclear and petrochemical industries.

The facilities at our Lillyhall works are also widely utilised for final assembly, mock-ups, testing & familiarisation training prior to the site installation of equipment. We have developed a flexible and responsive manufacturing service which can be applied across a wide range of task size. PPS Electrical also manufacture a wide range of E&I control panels which have been installed across the Sellafield site..


Our Decontamination expertise covers the delivery of hands on decontamination and R&D activities, using Ultra High Pressure water jetting, Chemical decontamination, CO2 blasting, concrete scabbling and ice pigging. We have also carried out blockage removal and pipework cleaning in nuclear facilities, minimising effluent production, utilising techniques such as water jetting, mechanical scouring, chemical dissolution and pressure pulsing. We also produce decontamination strategies and option studies fully underpinned by technical assessments and experience.

Restoration and Renovation

Shepley became established as a specialist restoration and conservation contractor in 1985 when we completed a major iron project on the Grade 1 listed Dorchester Hotel on Park Lane, London. Since that time we have been engaged as the specialist contractor on numerous large high profile restoration schemes as well as a vast array of smaller private commissions. We have made significant investments in the specialist resources which are essential to deal with the unique challenges within this sector and this includes the promotion of trainees through the various key craft skills. We have also made significant investments in our facilities which are capable of dealing with all aspects of the work from the initial cleaning processes, through the various restoration tasks to the application of a range of protective coatings. In all cases our approach is carefully considered to provide a sympathetic solution which can involve a blend of conventional craft skills along with technologies which help us protect the historic fabric.
