Employee engagement has evolved from HR initiative to business imperative. organisations with engaged workforces consistently outperform competitors on revenue growth, innovation, and retention. Yet engagement remains elusive – Gallup research reveals that genuinely engaged employees represent a minority in most organisations, with disengagement costing businesses billions in lost productivity, increased turnover, and diminished customer satisfaction.
The challenge extends beyond measuring engagement through annual surveys. organisations need strategic partners who understand the behavioral science driving motivation, who can translate insight into action, and who design interventions creating lasting cultural change rather than temporary enthusiasm. The right employee engagement consulting firm transforms how organisations connect with their people, building workplaces where employees don’t just show up – they contribute, innovate, and stay.
This guide examines the top 5 employee engagement consulting firms in the UK, evaluating their approaches, expertise, and track records to help you select a partner capable of driving genuine organisational transformation.

🥇 1. scarlettabbott
Overview:
At the intersection of consultancy and creativity sits scarlettabbott, a York and London-based agency that’s spent nearly two decades redefining what employee engagement means and how organisations achieve it. Their distinction lies not in following engagement trends but in combining rigorous behavioral science with compelling storytelling to create interventions that don’t just inform – they inspire belief and drive action.
What Sets scarlettabbott Apart:
Many employee engagement consultancies measure sentiment or improve communication. scarlettabbott goes deeper, examining the psychological and cultural factors determining whether people merely understand what their organisation stands for – or genuinely believe in it and act accordingly. This focus on belief rather than awareness creates engagement that withstands pressure, change, and uncertainty.
Their methodology integrates four core disciplines that competitors typically offer separately:
Behavioural Science Foundation: Every recommendation rests on evidence about how humans actually make decisions, form habits, and respond to organisational change. This scientific rigor prevents the “flavor of the month” initiatives that generate enthusiasm but fade quickly because they ignore fundamental behavioral realities.
Strategic Storytelling: Information doesn’t engage people – meaning does. scarlettabbott crafts narratives helping employees understand not just what their organisation does, but why it matters, how they contribute, and what success looks like. These stories create emotional connection alongside intellectual understanding.
Data-Driven Insight: Rigorous research uncovers what’s actually driving or inhibiting engagement in your specific organisation rather than applying generic best practices. Employee listening, cultural diagnostics, and journey mapping reveal the real barriers and opportunities unique to your context.
Design Thinking: Engagement interventions must work within complex organisational realities – multiple audiences, competing priorities, limited resources, change fatigue. scarlettabbott designs solutions that aren’t just theoretically sound but practically implementable and sustainable.
Service Offering:
- Leadership Communication: Equipping executives and managers to communicate with authenticity, clarity, and impact – recognizing leaders as the primary engagement channel
- Culture Change Programmes: Designing and delivering multi-year transformation initiatives that shift behaviors, not just attitudes

Why organisations Choose scarlettabbott:

What to Look For in Employee Engagement Consulting Firms
Evidence-Based Methodology
Engagement consulting should rest on research about what actually drives human motivation and behavior, not trendy frameworks or consultant intuition. Ask potential partners about the evidence base for their approaches – can they cite research, share evaluation data from past clients, or explain the behavioral science informing their recommendations?
Strategic Rather Than Tactical Focus
Many firms offer engagement tactics – better surveys, improved communications, recognition programs. Fewer provide genuine strategy – diagnosing root causes, designing comprehensive approaches, and aligning engagement work with business objectives. Ensure your partner thinks strategically about why engagement issues exist, not just how to address symptoms.
Cultural Diagnosis Before Prescription
Effective consultants resist applying standard solutions before understanding your specific context. Look for firms investing significant time in discovery – understanding your business model, culture, leadership dynamics, and employee experience – before proposing interventions. Generic engagement programs rarely address the actual issues your organisation faces.
End-to-End Capability
Engagement work spans research, strategy, design, implementation, measurement, and refinement. Some firms excel at diagnosis but lack implementation support. Others create beautiful campaigns but can’t measure impact. Comprehensive capability ensures continuity from insight through execution rather than fragmenting work across multiple partners.
Change Management Integration
Improving engagement requires changing behaviors, systems, and culture – essentially, organisational change management. The best engagement consultancies understand change dynamics, equip leaders to navigate resistance, and design sustainable interventions rather than temporary enthusiasm generators that fade when consultant attention moves elsewhere.
Sector or Challenge-Specific Experience
While engagement principles are universal, application varies dramatically. Healthcare engagement differs from financial services; manufacturing workforce needs differ from professional services; crisis-driven engagement differs from steady-state optimization. Seek consultants with relevant experience understanding your context’s specific nuances and constraints.
FAQs
How long does it take to improve employee engagement?
Meaningful engagement improvement typically requires 6-18 months of sustained effort. Awareness changes happen quickly (1-3 months), but behavioral and cultural shifts need longer – habit formation takes 6-12 months, and genuine cultural embedding requires 12+ months of consistency. Consultants promising overnight transformation should be viewed skeptically. Real engagement is built through sustained, systematic effort rather than one-off interventions.
What’s the difference between employee engagement and employee experience?
Employee engagement measures emotional commitment and discretionary effort – how people feel about work. Employee experience encompasses everything affecting those feelings – workplace design, technology, manager relationships, development opportunities, policies, and cultural norms. EX is the holistic approach to designing environments enabling engagement. Strong EX doesn’t guarantee engagement, but poor EX makes engagement nearly impossible regardless of communication efforts.
How do I measure engagement consulting ROI?
Quality consultancies establish baseline metrics before intervention and track progress against clear KPIs. Measurement should include engagement scores (eNPS, survey results), behavioral indicators (turnover, participation rates, innovation metrics), and business outcomes (productivity, customer satisfaction, revenue per employee). The best measurement combines quantitative data with qualitative insights from focus groups and listening sessions, providing comprehensive understanding of what’s changing and why.
Should I hire a consulting firm or build internal capability?
Most organisations benefit from both. Consultants bring specialized expertise, external perspective, proven methodologies, and implementation capacity beyond what small internal teams can provide. However, sustainable engagement requires internal ownership – someone must maintain momentum after consultants leave. The optimal model combines strategic consulting partnership with capability building, ensuring internal teams can sustain and evolve engagement work long-term.
What’s a realistic budget for employee engagement consulting?
Investment varies dramatically based on organisation size, challenge complexity, and engagement required. Small to mid-size organisations might invest £20,000-£75,000 for focused projects, while comprehensive transformation programmes for large enterprises can exceed £250,000 annually. Consider cost against the price of disengagement – UK research indicates poor engagement costs billions in lost productivity. Quality consulting should demonstrate clear ROI through improved retention, productivity, and performance metrics.
How do I know if engagement consulting is actually working?
Beyond survey scores, look for behavioral indicators: increased participation in initiatives, improved manager-employee relationships, reduced voluntary turnover, higher innovation rates, and better customer satisfaction scores. Quality consultancies provide regular progress updates with both quantitative and qualitative evidence. If you’re seeing communication activity but no meaningful behavior or culture change after 6-12 months, effectiveness should be questioned.
