Years of Power BI delivery
From first-generation Power BI through to Microsoft Fabric and Direct Lake architectures.
Infrastructure, Business Apps or Managed Services
We do Power BI and Microsoft Fabric. That is it. No generalist distraction.
Senior-led engagements
No junior-rotation model. The Power BI expert scoping your project delivers it.
Focused Power BI consultancy
Our Power BI consultants work with UK organisations across the UK, remote and on-site.
Power BI is at the heart of what we do
Metis BI is a UK-focused Power BI consultancy and Microsoft Fabric partner. We work exclusively on the Microsoft data and analytics stack (Power BI, Microsoft Fabric, and the surrounding Power Platform), which means the Power BI consultant on your project is a genuine Power BI expert, not a generalist who also does SharePoint and Azure.
Every Power BI consultancy engagement is led by senior Power BI experts with ten or more years of Microsoft business intelligence experience. Every solution is shaped to how your organisation actually works, not built from a template.

The problem is not buying Power BI. It is getting value from it.
Microsoft Power BI is the market-leading business analytics tool and data visualisation platform, used by more than 97% of Fortune 500 companies. Power BI connects to hundreds of data sources including SQL Server, Azure, Snowflake, Dynamics 365, Excel and Microsoft 365, and delivers interactive reports and dashboards that help teams make smarter, data-driven decisions across the organisation.
The problem most organisations face is not buying Power BI. It is turning Power BI from a licence line into a reliable, governed Power BI solution that delivers actionable insight. Reports are built quickly, semantic data models become tangled, governance is skipped, and within twelve months the Power BI estate is a maintenance burden rather than an analytics capability.
A specialist Power BI consultancy changes the outcome. The Power BI consultant you are working with does this every day, across many organisations, in Power BI Pro, Power BI Premium and Microsoft Fabric environments.
Three principles that separate a Power BI consultancy that delivers from one that does not
01 — Foundation
Governance first
Every Power BI consultancy engagement we deliver starts with how the Power BI solution will be governed — who owns the data, who develops the reports, how access is controlled. Governance is what lets Power BI scale from one dashboard to an organisation-wide capability that helps leaders make data-driven decisions with confidence.
02 — Craft
Semantic data models that hold up
Power BI reports are only as good as the data model behind them. Our Power BI consultants build star-schema semantic models with well-structured DAX, calculation groups and field parameters. Poorly built Power BI data models are the single biggest reason BI solutions become unmaintainable.
03 — Outcome
Client independence
Every Metis BI engagement is designed to leave your team more capable than it was before. We train your analysts, document the Power BI solutions, and transfer ownership properly so your internal team becomes the long-term owner of a Power BI capability we helped them build.

Lazaros Viastikopoulos
Founder & Principal Consultant
Metis BI is led by Lazaros (Laz) Viastikopoulos, who previously ran the Power BI practice at Telefónica Tech Data & AI (formerly Adatis). Laz has spoken at SQLBits, Data Relay, SQL Saturday and Power BI User Groups across the UK, with more than a decade of enterprise Power BI delivery.
He founded Metis BI to deliver the calibre of Power BI work a specialist consultancy can do without the overhead and generalist distraction of a multi-service Microsoft partner. Our Power BI consultant team combines Power BI developers, data engineers and governance specialists, every one of whom works on Power BI and the Microsoft data stack as their primary discipline.
The answers to your questions.
A Power BI consultancy helps organisations unlock full value from Microsoft Power BI — from first deployment through to enterprise-scale governance. Services typically include semantic model design, DAX development, Power BI report and dashboard build, governance frameworks, training, licensing support services, and migration from legacy BI tools. At Metis BI, our Power BI consultants combine technical Power BI expertise with practical experience of how business analytics actually gets used inside UK organisations.
A generalist Microsoft partner sells Power BI alongside SharePoint, Intune, Azure and Dynamics — Power BI is one of many services. A specialist Power BI consultancy works on Power BI as its primary discipline, which shows up in semantic data model quality, DAX fluency, governance depth, and currency of knowledge on new Power BI and Microsoft Fabric features.
Power BI consultancy pricing depends on scope — a focused semantic model build might be 10-15 days, a governance review and report development engagement 20-40 days, and an enterprise migration significantly more. UK Power BI consultant day rates typically range from £750 to £1,200. Metis BI works to transparent day-rate pricing with clearly defined scope and milestones, so you know what you are paying for at every stage.
Yes. A significant proportion of our Power BI consultancy engagements are with organisations that already use Power BI but are struggling with performance, governance gaps, broken semantic data models, or the transition to Microsoft Fabric. Our Power BI support services and optimisation assessments are a common starting point.
Fabric changes both the architecture and the licensing of Power BI. Architecturally, Power BI now sits on top of OneLake and consumes data through Direct Lake. Commercially, the shift from P-SKU to F-SKU capacity typically reduces cost and increases flexibility.
Yes. We deliver role-based Power BI training for developers, analysts and business users, tailored to each client's semantic model and Power BI reports. Training is built into every engagement because client independence is one of our core delivery principles.
