About Rockatek

Rockatek Ltd is an Engineering Consultancy based in Gloucester in the United Kingdom, offering Analysis, Design and Testing services across a wide range of industries.

Rockatek specialises in Engineering solutions for harsh environments. Its mission is to use experience and expertise to develop and enhance clients’ products, systems and processes to provide cost efficient solutions. Rockatek also offers a Forensic Engineering consultancy and a robust in-house verification test service to verify complex design analyses and to demonstrate known failure modes to clients.

The company was established in 2016 by three experienced Chartered Engineers (MIMechE) with more than 35 years combined experience in Mechanical, Electronics and Systems Engineering. This is achieved by combining all the necessary disciplines including a First Principles approach to Engineering, Mathematical Modelling and Finite Element Analysis (FEA), Computer Aided 3D and 2D Design (CAD) and Project Management.

Rockatek’s philosophy is to work closely with clients with a focus on Project Management from design and analysis, through the supply chain to prototypes, qualification testing and Operations. To ensure the service is executed at the highest possible standards, Rockatek operates an ISO 9001:2015 certified Integrated Quality Management System. See the Rockatek ISO 9001:2015 certificate here.

Operations and Project Management

Rockatek’s consultants are competent in all aspects of Operations and Project Management. In order to maximise efficiency, Rockatek operates a lean Design and Engineering service from concept generation to project handover.

Rockatek projects are controlled through an internal stage gate process in line with customer requirements. Staged solutions are offered as well as formal design and progress reviews before progression to the next project phase. Each project is assigned a dedicated Engineering Consultant to manage the project through to completion.

Rockatek uses a robust Product Data Management (PDM) system to manage document configuration and to control design changes. This configuration control process extends to specifications, CAD models, drawings, assemblies, bills of materials, design standards and technical reports.

Rockatek offers an Operations and Project Management consultancy service. Our consultants can assess a client’s existing systems and process controls and highlight areas for refinement and improvement. Rockatek will typically investigate performance to existing KPIs and KFIs and provide feedback on the effectiveness of existing measures. This is a bespoke service tailored to the client’s needs and as such, requires a detailed initial discussion with the client’s management team as the scope can vary considerably.

Rockatek also offers a Supply Chain Management service targeted at the procurement of complex engineering components. Typically, such components will require a number of subcontract process steps including specialist machining, heat treatments, surface treatments and NDT.


“Lee Products Ltd has worked with the Directors of Rockatek for over fifteen years in the Down Hole Oil Tool market, specifically in the field of high pressure hydraulics. Jim, Dan Crowley and Dan Minett-Smith have the technical knowledge, vast experience and commercial acumen to give any project tangible results.

The one thing that impresses me most in B2B is when smart engineers/innovators can communicate ideas, data, and give succinct, understandable explanations of complex systems to any audience. These guys can do this in abundance and do it with passion and enthusiasm. We look forward to working with Rockatek again”.

“I have worked closely with the Rockatek Directors for many years. They have a proven track record of increasing product capability and reliability to offer solutions to real life engineering problems. Their ability to verify design improvements and new designs with analysis AND physical testing is invaluable to customers. The guys are thorough and professional. I wouldn’t hesitate to recommend their services to any company, large or small, who require expert engineering design, analysis and testing services”.

“It is great to meet a team of engineers who can hit the ground running with a strong history of working effectively together. It is very interesting to see how they quickly start to scope out the pros and cons of a project and evaluate the various possibilities”.

“Nationwide Windows have been working closely on a project to design and manufacture a door trolley that could be used by our Operatives as a mechanical aid to assist manual handling activities. James has been open to my feedback throughout the design process and made changes accordingly. The product was delivered on time, as specification and the build quality was as expected. Should Nationwide require further trolleys I would be happy to place a repeat order”.

“I have worked with James and the team at Rockatek Eng Consultants recently, their approach to solving engineering problems is effective and efficient. The engagement with them has been very professional at all times. They have an extensive knowledge of the ANSYS suite of simulation, and clearly demonstrate this with a pro-active and efficient approach to engineering tasks. If you require engineering simulation then I would encourage you make contact with the team at Rockatek Engineering Consultants”
