Power BI Implementation in London

Implementing Power BI for London organisations, where the data model decides almost everything that follows. Report performance, calculation complexity and whether measures behave as expected all follow from how tables relate — and a flat spreadsheet-shaped import produces a report that is slow to refresh and awkward to extend.

Why this comes up

The problem

Everything was imported as one wide table, the calculations are increasingly convoluted, and refresh takes twenty minutes.

What you get

What we deliver

  • A star schema built rather than importing source tables as they arrive
  • Relationships defined properly so filters propagate as users expect
  • Measures written against the model rather than compensating for its shape
  • Refresh strategy chosen — import, direct query or a combination — per requirement
  • Row-level security implemented where different users must see different data
  • A shared dataset established so reports build on one model rather than several

Want this scoped for your business in London?

Thirty minutes, no charge, no sales script. You leave with a written summary of what power bi implementation would actually involve — whether or not you use us.

Power BI Implementation in London — common questions

Why does the model matter more than the visuals?
Because everything else depends on it. A well-shaped model makes calculations short and reports fast; a flat table makes every measure work around the structure, and the resulting complexity compounds with each new requirement.
What is wrong with one wide table?
It duplicates data, inflates the file and makes filtering ambiguous. Splitting facts from dimensions reduces size substantially and gives you relationships that behave predictably, which is what stops measures returning results nobody can explain.
Import or direct query?
Import for speed where the data fits and a scheduled refresh is acceptable; direct query where data must be current or is too large to import. Mixing them per table is common and it needs deciding deliberately rather than by default.
Should reports share one dataset?
Where they cover the same subject, yes. Separate datasets per report means the same logic maintained several times and the same figure calculated differently, and consolidating later is considerably harder than establishing a shared model at the outset.
Do you work with businesses across Greater London?
Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of London businesses do you usually work with?
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
Do you cover the areas around London?
Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
