Steadfast Innovation provides end-to-end mechanical engineering expertise — from early design and analysis through prototyping, development and full productionisation. Wherever you are in the journey, we bring the rigour to move it forward.
Steadfast Innovation delivers mechanical engineering expertise at every stage — from first sketch to production-ready product. We don't just design it; we make sure it can be built.
Concepting, optioneering and detailed mechanical design — from initial sketches through to full manufacturing drawings, modelled in 3D CAD.
Enquire → 02Specialist finite element analysis and structural simulation to validate your designs under real-world loading — reducing risk before committing to hardware.
Enquire → 03Turning designs into tangible prototypes — managing the build, iterating quickly and de-risking development before scale-up. We support you through the messy middle.
Enquire → 04Physical and analytical testing to verify performance against specification. We produce test protocols, reports and calculations to support sign-off and regulatory compliance.
Enquire → 05Preparing your design for volume manufacture — Design for Manufacture (DfM), supply chain engagement, tolerance analysis and production documentation to get your product built at scale.
Enquire → 06Engineering rigour applied to early-stage innovation. We help explore novel technical solutions, assess feasibility and support grant applications and research programmes.
Enquire →Translating your requirements into engineered solutions — from brief to detailed 3D design.
FEA, calculations and systems modelling to validate performance before a single part is made.
Managing the prototype build, iterating on findings and de-risking the design in the real world.
Structured testing against specification. Reports, data and evidence to underpin confidence and compliance.
DfM reviews, supplier engagement and production documentation — ready to manufacture at volume.
Steadfast Innovation Ltd is a mechanical engineering consultancy based in Lockerbie, Scotland. Founded by Chartered Mechanical Engineer Stephen McEvoy, we provide high-quality engineering services to clients across the UK and worldwide.
What sets us apart is our ability to take a project all the way — from early design and simulation through hands-on prototyping, development and ultimately productionising for manufacture. We understand that the journey from idea to production is rarely straightforward, and we're built to support you through every step.
Our extended network of specialists means we can bring in the right expertise when needed:
We offer three engagement models to suit the nature of your project — ensuring transparency on scope, cost and delivery from day one.
Hourly-rate support with a defined limit of liability. Scope and hour estimate communicated upfront — ideal for ongoing or exploratory work where flexibility is needed.
A fully scoped work package at an agreed fixed price, delivered via a formal proposal document. Best suited to well-defined projects requiring cost certainty.
Discounted ongoing support based on an agreed contract. Suited to longer-term relationships or projects where Steadfast Innovation forms part of your extended team.
Based in Lockerbie, Scotland — supporting clients across the UK and beyond. Send us an enquiry and we'll come back to you promptly.
