Business transformation & change

Strategy that gets delivered.

Business transformation, organisation design and change for mid-market UK companies (250 to 2,000 staff). 26 years of senior HR experience behind every programme.

  • Founder-led, every engagement personally overseen
  • Former HR Director
  • Yorkshire-based, working UK-wide

Most transformations don't fail on strategy. They fail on people.

  • The org design

    that ignored how work really flows.

  • The change plan

    that lost the middle managers.

  • The restructure

    that kept the wrong leaders.

I help mid-market UK companies design and deliver transformation, restructure and change without that happening.

I bring 26 years of senior HR experience to the part of transformation everyone underestimates. Most consultants treat the people side as a workstream. I treat it as the part that decides whether the whole programme lands.

How I work

What I do

Three ways to work together.

No menu of HR products. A defined programme, senior cover when you need it, or leadership training your managers will actually remember.

Strategy executed at pace.

Business Transformation & Change

Defined programmes delivered in short cycles with frequent checkpoints and real outputs along the way. Not a 200 page report at month six.

  • Business transformationOperating models, ways of working, post-merger integration.
  • Organisation designRoles, teams, spans of control and decision rights.
  • Change managementEngagement, leadership alignment and adoption.
  • Growth & downsizingTUPE, redundancy, workforce planning, restructure.

In place fast. Gone when the work is done.

Interim & Fractional Leadership

Interim HR Director, Transformation Director and Change Lead roles, or ongoing part-time senior HR leadership. Weekly progress, fortnightly reviews, a clear handover plan from day one.

Call me when a leader has left mid-programme, the transformation needs senior ownership, or you're between hires and the work can't wait.

What clients say

Don't take my word for it.

Kate demonstrated a rare combination of energy, creativity and precision. Her collaborative style, clear communication, and ability to balance detail with a broader perspective were instrumental in delivering compliant, successful outcomes. The project has significantly strengthened our compliance and reporting functions, while also leaving behind a more connected and capable team.
Lisa WheatcroftPeople Director, MTR Elizabeth Line
She quickly gained the respect and trust of the Exec Team and staff alike, partnering very well with HR in working out what a successful launch would look like and putting in place the necessary resources to make that happen. I would highly recommend Kate and People Efficient without hesitation.
Julia HowellsHead of HR, Nextbase
Kate made an exceptional technical, strategic and operational contribution to the success of the mobilisation... Working within an ambitious timeframe and under significant pressure, she remained calm, organised and solutions-focused, helping to ensure the mobilisation was delivered seamlessly and to an exceptionally high standard.

Meet Kate

Hello. I'm the person who actually turns up.

I'm Kate Maddison-Greenwell. I've spent 26 years in senior HR, including HR Director roles, and I've led transformation and change from the inside. I've seen what makes programmes land and what makes them quietly unravel. It's nearly always the people side.

I'm also a trained actor. That sounds like a left turn. It isn't. It's why I read a room well, why I listen properly, and why the managers I work with rehearse the hard conversations instead of just reading about them.
