Prototype Development

Prototype Development for Energy & Clean Technology

Have an idea? A design? Or a concept you want to bring to life — without heavy upfront investment?

At Mechanical Services International, we specialise in supporting start-ups, scale-ups and established companies within the energy and clean technology sectors who need prototype equipment built, tested and refined, but don’t manufacture in-house.

Based in Great Yarmouth, we work with clients across renewables, clean energy, offshore and industrial sectors to turn early-stage ideas into functional prototypes. Whether you’re developing a proof-of-concept, test rig, pilot equipment or first-off build, we provide practical engineering support from fabrication through to assembly and testing.

We understand that prototyping is rarely straightforward. Designs evolve, challenges arise, and requirements change. Our experienced engineers adapt quickly, suggest practical solutions, and make changes on the fly to keep development moving — without unnecessary cost or delay. This flexible, problem-solving approach is especially valuable for new technologies and emerging concepts.

For established businesses, we act as a trusted build partner when specialist equipment is required but internal manufacturing capability isn’t available.

Confidentiality is fundamental to our work. Your designs, data and intellectual property remain protected, with all prototype development carried out discreetly within our workshop.

If you’re looking for a practical engineering partner to help develop, build and refine prototype equipment, we’re ready to support you.
