Semantic models and DAX
A star schema your measures can rely on, one definition per KPI, and DAX that a new analyst can read. Most report problems we are asked to fix start in the model, so this is where we start too.
Power BI · United KingdomPower BI Consultancy for UK Organisations
Senior Power BI consultants who build models your numbers can rely on, reports people use, and the security and refresh behind them. UK office in Twickenham, delivery on UK business hours, fixed prices in GBP.
Why teams call us
Power BI is easy to start and hard to scale
Most UK organisations we speak to already use Power BI. The first reports went well. Then the estate grew: dozens of datasets with their own copy of the same tables, revenue that differs between the finance pack and the sales dashboard, refreshes that fail overnight, and one person who understands the DAX.
That is the point where a Power BI consultancy earns its fee. We put a shared semantic model under the reports, agree one definition for each measure, set up security and deployment properly, and leave your team able to run it. If the next step is Microsoft Fabric or Copilot, the same model is what makes that step work.
Our team holds current Microsoft certifications in Power BI (PL-300) and Fabric (DP-600, DP-700). If your reporting is part of a wider data platform, see our Microsoft Fabric and Power BI consultants UK page.
What we do
Power BI consulting services
Seven areas cover most of the Power BI work UK clients bring us. Many projects touch three or four of them.
Report design
Reports built around the decision someone has to make, not around the data that happens to be available. Clear page structure, sensible visuals and a consistent theme, so a board pack and an operational report feel like the same product.
Refresh and performance
Slow visuals, refreshes that time out, gateways that fall over at 7am. We trace the cause with Performance Analyzer and DAX Studio, then fix the model, the query or the storage mode rather than adding more capacity.
Premium Per User to Fabric and Direct Lake
Moving from Premium Per User or a P SKU to a Fabric capacity, and deciding which models should move to Direct Lake on OneLake. We size the F SKU against your real usage and plan the cutover so reports keep working on Monday morning.
Copilot in Power BI
Copilot answers well only when the model underneath is clean: clear names, descriptions, synonyms and sensible relationships. We prepare the model, set up the capacity and tenant settings, and agree who should use it first.
Row-level security
Row-level and object-level security that matches how your organisation is actually structured, tested against real user accounts, and documented so it survives the next restructure.
Training
Hands-on sessions for report builders and model owners, run on your own data where possible. The aim is a team that can maintain what we built, not one that has to call us for every change.

FAQ
Power BI consultancy in the UK: common questions
A Power BI consultancy designs and builds the parts of Power BI that are hard to get right in-house: the semantic model, DAX measures, security, refresh and capacity, and reports people trust. Solv Systems does this for UK organisations from our office in Twickenham, with delivery on UK business hours. We also fix existing estates, migrate from Premium Per User to Fabric, prepare models for Copilot and train internal teams.
It depends on scope more than on day rate. Our UK Power BI project cost guide puts most projects between £2,500 for a single focused report and £250,000 for an enterprise rollout, excluding VAT. We quote a fixed GBP price after a short discovery, so you know the cost before you commit. Microsoft licensing, such as Power BI Pro or a Fabric capacity, is paid to Microsoft separately.
A contractor suits a well-defined task where your team already owns the design. Power BI consultants suit work where the design itself is the problem: a model that does not scale, numbers that do not match between reports, or a migration with several moving parts. With Solv Systems you get a team rather than one person, so holidays and illness do not stop delivery, and you can also take a consultant on staff augmentation terms if a single person is what you need.
Our UK office is in Twickenham, south-west London, and your engagement lead is UK-based. Workshops, kick-offs and steering meetings can be held at your London office. Day-to-day delivery runs remotely on UK business hours, which keeps costs down without slowing anything.
Yes. We work with organisations across the UK, including Manchester, Birmingham, Leeds, Bristol, Edinburgh and Glasgow. Delivery is remote on UK hours, and we travel for workshops and key meetings where being in the room helps.
Usually, yes. Slow reports are most often caused by the model rather than the visuals: too many columns, bi-directional relationships, heavy calculated columns or DAX that scans the whole fact table. We measure first, then fix the specific causes. A rebuild is only worth it when the model structure itself is wrong, and we will tell you if that is the case.
Not automatically. Premium Per User is often the cheapest option for a small number of report builders and viewers. A Fabric capacity starts to make sense when many people need to view reports, when you want Direct Lake or other Fabric workloads, or when you want Copilot. We compare the licensing cost for your actual user numbers before recommending a move.
It can be. Your Power BI tenant and Fabric capacities can sit in Azure UK South or UK West. We sign UK-enforceable Data Processing Agreements and configure workspaces, security and sharing settings to meet UK GDPR and your own internal controls.
