Power BI Migration · London
Power BI Migration in London
Migrating London organisations onto Power BI from another reporting platform, where the model has to be rebuilt rather than converted. Every tool shapes data differently, so the useful question is not how to translate the old reports but which of them anyone still uses — and that answer is usually a fraction of the total.
Why this comes up
The problem
There are four hundred reports on the legacy platform and the migration plan assumes all of them are coming across.
What you get
What we deliver
- Usage measured on the existing platform, so migration effort follows real demand
- Reports triaged into rebuild, consolidate and retire
- The data model designed for Power BI rather than mirroring the old structure
- Calculations rewritten against the new model, since translation rarely works
- Users involved in verification, because they know when a figure looks wrong
- The old platform decommissioned once each area is signed off

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Power BI Migration in London — common questions
- Do we need to migrate every report?
- Almost certainly not. Usage data on the existing platform typically shows a large proportion opened rarely or never, and migrating those spends real effort reproducing something nobody will look at once it arrives.
- Can calculations be translated?
- Rarely cleanly. Expression languages differ in how they handle context and filtering, so a literal translation frequently produces something that returns the right number in one situation and the wrong one elsewhere — rebuilding against the new model is safer.
- Who should verify the results?
- The people who use the reports. Technical reconciliation confirms totals match; only the person who reads a report weekly notices that a category has been mapped plausibly and wrongly, and that class of error survives every check except theirs.
- When can the old platform be switched off?
- Area by area, as each is signed off. Keeping it available indefinitely means paying for both and gives people a reason not to adopt the new one, so a defined retirement date per area is what actually completes a migration.
- 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.
