CX, process & change consultancy

We help organisations reduce customer churn by fixing the problems behind it.

The reasons a customer leaves are never obvious. There’s no single failure, no clear moment where things went wrong - just a growing sense that people are slipping away, and the organisation is working harder for diminishing returns.

Carter Consultancy helps senior leaders uncover what’s really driving churn, slow delivery and stalled change. By starting with customer experience and working through process and culture, we deliver practical improvements that teams adopt, use and sustain.

  • Get clarity on what’s actually driving customer churn
  • Align teams so work flows instead of stalling in silos
  • Build momentum through practical improvements that stick

Dave gets people up out of their seats and engaged. Individuals quickly link the concepts back to real-life scenarios in their day-to-day roles - even the most stand-offish find themselves getting involved.

Is this you?

Does this feel familiar?

Five patterns we see again and again inside organisations where customer experience, process and culture aren’t pulling in the same direction.

Dave Stubberfield presenting Carter Consultancy’s 1% Club performance framework.
  • 01

    Customers are leaving - or disengaging - often without a clear single cause.

  • 02

    Strategy is agreed at the top but falls apart in delivery.

  • 03

    Teams work hard but operate in silos, duplicating effort or handing work off blindly.

  • 04

    CX, engagement or transformation initiatives start well, then quietly fall apart.

  • 05

    Leaders spend more time firefighting than leading.

You’ve got the strategy - you need better systems.

Our approach

How it works

This work isn’t about frameworks or theory. It’s about execution, momentum and sustainability.

  1. 01

    Discovery and diagnosis

    Understand what is really happening on the ground, not just what reports say. We speak to leaders and teams to surface misalignment early and identify where value is being lost.

  2. 02

    Focus and prioritisation

    Rather than trying to fix everything, we help prioritise a small number of visible, measurable improvements that build credibility and momentum fast.

  3. 03

    Implementation and improvement

    Workshops are combined with hands-on delivery. Improvements are designed around real people, real customers and real constraints.

  4. 04

    Make it stick

    Tools and templates are shared openly. Coaching and soundboard support is provided. Simple operating rhythms, KPIs and reviews are embedded so progress compounds rather than fades.

About us

Practical change that delivers results - and sticks.

Carter Consultancy is an independent consultancy specialising in customer experience, process improvement and change.

We work hands-on inside complex organisations and understand why well-intentioned initiatives often fail. Strategy is rarely the problem. Execution is.

We are comfortable working at every level of a business - from boardroom to frontline - translating strategy into action and giving teams the tools and confidence to improve how they work.

Our approach is grounded in common sense, empathy and execution. No jargon. No big-bang programmes. Just practical change that delivers results and sticks.

Mission, vision, values

What we stand for.

Our Mission

To help organisations deliver practical, lasting change by working alongside their people - not above them. We exist to close the gap between good intentions and real results.

Our Vision

A world where change programmes succeed because they start with people, not PowerPoints. Where improvement is a daily habit, not an annual initiative. And where leaders have the clarity, confidence and support to make it happen.

Honesty first.

We tell it straight. Real progress starts with an honest picture of where things stand, even when that’s uncomfortable.

Practical over perfect.

We’d rather deliver something useful this week than something polished next quarter. Momentum matters more than theory.

People at the centre.

Change doesn’t happen in boardrooms or slide decks. It happens when the people doing the work understand it, believe in it, and own it.

Hands-on, always.

We don’t advise from the sidelines. We work inside the organisation, alongside teams, where the real work gets done.

Built to last.

We measure success by what continues after we leave, not by how long we stay. Every engagement is designed to reduce dependency, not create it.

Case study

Currys: when a small operational decision became a brand issue

The context

Currys operates at national scale, where thousands of small operational decisions quietly shape how the brand is perceived by customers and the public.

The challenge

A health and safety decision removed jet-wash facilities from delivery depots. As a result, delivery vans began leaving warehouses visibly dirty. On the surface, this felt like a minor operational issue. In reality, it was eroding brand trust every time a van arrived at a customer’s home or drove through a neighbourhood.

No single team owned the problem. Health and safety had made a reasonable decision in isolation. Delivery teams felt the impact but lacked a route to challenge it. Silos meant the wider consequence was invisible.

The intervention

Through customer experience work and frontline engagement, delivery teams were encouraged to look at the situation through the customer’s eyes and ask a simple question: what does this signal about us as a brand?

That perspective gave teams the confidence to raise the issue constructively. Rather than confrontation, the conversation focused on impact. Health and safety were brought into the discussion, context was shared, and assumptions were challenged.

The outcome

A new, safer process was introduced. Staff were certified to use the equipment properly, jet-wash facilities were reinstated, and ownership was clarified.

The fix itself was simple. The impact was not.

A silo was broken. Frontline teams felt heard. A national brand issue was resolved - a small moment of customer experience improvement that demonstrated how asking the right questions, at the right level, leads to better outcomes.

The fix itself was simple. The impact was not.

If you know things aren’t working as well as they should - but don’t want another initiative that stalls - the next step is a focused discovery session.
