// Bristol-based RF & electronics engineering consultancy

We engineer what others can't build in-house

From bespoke RF systems and embedded firmware to full product design and prototyping — we're the technical partner that closes the gap between your idea and a working product.

// What we do

Engineering capability,
on demand

We embed into your team or deliver standalone — whatever your project demands.

Research & Development

Feasibility studies, technology evaluation, and concept development for novel electronics challenges. We take on the hard problems that require deep investigation before a line of schematic is drawn.

Product Design & Prototyping

End-to-end hardware development from initial schematics through advanced PCB layout — including high-density interconnect (HDI), controlled-impedance RF boards, and exotic substrate materials — through to BOM optimisation and working prototypes ready for manufacture. We design for manufacture from day one.

RF Systems

Antenna design, radio link budget analysis, radar systems, spectrum planning, and full RF system integration. From sub-GHz IoT to microwave and millimetre-wave — we work across the spectrum, backed by 3D EM analysis.

Firmware & Software

Bare-metal firmware, RTOS-based applications, BSP development, and supporting desktop software. We write lean, well-documented code that your team can maintain long after handoff.

// About us

Senior engineers,
not junior teams

Electro-Technical was founded by practising engineers who were frustrated with consultancies that sell senior expertise and deliver junior execution. Every project at Electro-Technical is handled by an engineer with at least a decade of relevant field experience.

We're based in Bristol — a hub for aerospace, defence, and deep-tech — and work with clients across the UK and internationally. We don't take on more than we can deliver exceptionally.

Our sweet spots are RF and wireless systems, analogue front-ends, and full-product embedded development where the hardware and firmware need to be designed in close coordination.

// How we work

From brief to build

A straightforward engagement model that keeps you informed at every stage.

Discovery call

Free 30-minute conversation to understand your challenge, timeline, and budget. We'll be direct about whether we're the right fit.

Scoped proposal

A clear statement of work with fixed milestones, deliverables, and pricing — no ambiguous day-rate retainers unless that's genuinely what you need.

Execution

Weekly written updates. Designs reviewed at each milestone. You retain full IP ownership of everything we produce for you.

Handoff

Full design files, documentation, BoM, and a knowledge transfer session. We structure handoffs so your team can own what we've built.
