Who we are

A boutique built from six careers in delivery.

Most transformation programmes don't fail on technology. They fail on layers — on the distance between the people who sell the work and the people who do it.

5i Consulting was founded by six practitioners who were tired of that distance. We keep teams small and senior, decisions fast, and accountability personal. When you engage us, the directors are in the room — architecting, building and assuring alongside you.

Our name carries our promise: six directors, five principles — Innovate, Integrate, Implement, Insight, Integrity — the discipline behind every programme we run.

Senior-led work

"The same people who scope it, build it."

No hand-offs to junior delivery pods. No frameworks layered to fill a day rate. Just senior practitioners, accountable end to end.

Our principles

Five i's. One standard of delivery.

Each principle maps to a discipline our directors own — and a reason clients in both sectors trust us with work that cannot fail.

i.

Innovate

AI-first thinking and emerging tech, applied to real problems — not hype.

ii.

Integrate

Connecting systems, data and platforms so the whole estate speaks one language.

iii.

Implement

Working software, on time, that survives contact with production and audit.

iv.

Insight

Strategy, analytics and intelligence that turn data into decisions.

v.

Integrity

Honest, accountable delivery — the rarest differentiator, and the one public bodies value most.

What we do

Transformation, end to end.

From the first discovery workshop to live managed service — capability that spans strategy, engineering and assurance.

Flagship solution

National electronic tolling, delivered end to end.

A modern toll system is a high-volume, real-time payments and citizen-services platform — exactly what we build. We lead the programme and build the national IT platform, integrate roadside hardware through specialist vendors, and extend the digital-payment rails a government already trusts.

Tiered, RFID-first, GNSS-ready — one back-office behind every bridge.

Where we work

Equally fluent in government and enterprise.

The discipline that satisfies a public-sector audit is the discipline that protects a commercial launch. We bring both.

Public Sector

Central and local government, health and national programmes — delivered to GDS standards, with accessibility and audit built in. Our directors have shipped national-scale work, including census-grade workforce platforms.

Central GovernmentLocal AuthoritiesHealth / NHSCensus & ONS

Private Sector

Financial services, media, automotive and staffing — high-stakes, integration-heavy programmes where compliance and customer experience both matter, and downtime isn't an option.

The 5i edge

Why clients choose a boutique over a behemoth.

The large integrators bring scale. We bring proximity. For programmes where senior judgement and accountability decide the outcome, that's the difference.

The big-integrator model

  • Senior names in the pitch, junior pods in delivery
  • Layers of process to defend a day rate
  • Slow decisions across competing teams
  • Rework absorbed quietly into the bill
  • You're one account among thousands

The 5i model

  • Directors architect, build and assure your work directly
  • Small, senior teams — no padding, no hand-offs
  • Fast decisions, lower rework, fewer surprises
  • Fixed principles: every line held to the five i's
  • You're a partnership, not a ticket number
How we deliver

A method that mirrors our name.

Innovate

Discovery, options and a target architecture that challenges assumptions.

Integrate

Design how systems, data and people connect across the estate.

Implement

Build, test and deploy in agile increments to a working Beta.

Insight

Measure outcomes, surface analytics and prove benefits realisation.

Integrity

Assure, secure and run — accountable through Live and beyond.
