One engineering discipline, every layer. Whether the system is a production Kubernetes platform, the application running on it or the hardware beneath, the fundamentals are the same: clear requirements, sound architecture, verified delivery.

Capabilities

Approach

How we work

Engagements are shaped around the outcome, not the other way round. Most work falls into one of three models.

Project delivery

Defined scope, defined outcome. We take responsibility for a work package — from interface specification to platform build — and deliver it to agreed acceptance criteria.

Embedded consultancy

Senior engineering capability within your team. We work inside your processes, tools and governance, raising delivery capacity without raising overhead.

Advisory & assurance

Independent review where confidence matters: architecture and design reviews, integration readiness assessments, and engineering assurance for safety-related change.

Experience

Experience where it matters

Our background is delivery in environments where failure is not an option: safety-related control systems and production cloud platforms. We are at home with assurance frameworks, formal interface management, and the realities of integrating new technology into operational infrastructure.

Safety-critical delivery
Assurance frameworks
Production cloud platforms

About

About 3B Consulting

3B Consulting Ltd is an independent engineering consultancy based in Bristol, United Kingdom. The practice is led by engineers whose delivery experience spans safety-related control systems, enterprise cloud platforms and full-stack software — and who remain hands-on across all three.

We keep the company deliberately small. Clients work directly with the engineers responsible for their outcome, with no account layer in between.
