GMT/BST — your working hours
Three Power BI problems London teams run into — and what they cost
UK-specific dynamics that slow down BI projects.
The problem
GDPR compliance left to last
A dashboard gets built, then someone in legal asks 'where is this data stored?' — and the answer is US East or a third-party SaaS. Six weeks of rework follows.
UK GDPR requires you to document the lawful basis for processing personal data, identify the data controller and processor chain, and confirm data residency. We complete this before writing the first DAX measure — not after.
The problem
Open-ended London contractor day rates
At £600/day, a 3-month contractor engagement costs £39,000 — often more than a fixed-scope project that delivers the same outcome faster.
London Power BI contractors bill by the day with no scope accountability. A fixed-price engagement with clear deliverables and a completion date is almost always cheaper than an open-ended day rate. We publish fixed GBP prices — no discovery call required to get a number.
The problem
Offshore builds that can't support UK compliance requirements
An offshore team delivers a dashboard that stores data in US East or processes personal data without a Data Processing Agreement. UK GDPR Article 46 safeguards are missing.
Offshore BI delivery is cheap for a reason. GDPR documentation, Azure UK South data residency, and FCA-regulated firm vendor onboarding requirements are rarely included in an offshore scope. You discover the gaps when legal reviews the build — months later.
UK GDPR compliant from line one — not bolted on at the end
Every engagement starts with a GDPR data mapping exercise at no extra cost. We identify what personal data flows through your Power BI model, document the lawful basis, and design row-level security before the first report is built.
Azure UK South is our default data residency recommendation — UK GDPR and EU GDPR dual compliance. For FCA-regulated clients we document the full data flow and can work within your vendor onboarding process.
We sign a Data Processing Agreement before any data is shared. NDAs are standard. For financial services clients we understand SYSC operational resilience expectations and design accordingly.
DAX measures are written against your specific data model — not generic templates. Every measure is reconciled against your source numbers before you see it. We do not mark a dashboard as done until the delta is under 1%.
When we hand off, you own everything. .pbix files, documented semantic model, training session, and a 30-day hypercare window. Nothing disappears if you stop working with us.
Power BI for London's dominant sectors — not a generic playbook
We have built Power BI for financial services, pharma, and professional services firms with UK-specific compliance requirements.
Do you have experience with FCA-regulated firms?
Yes. We have delivered for FCA-authorised asset managers and payment institutions. Our builds include: PRA stress test reporting views, treasury dashboards with Bloomberg data, FCA supervision data in GABRIEL format, and SYSC operational resilience monitoring. We understand the FCA's expectations for third-party vendor governance and can work within your TPRM process. Azure UK South data residency and a signed DPA are standard on every financial services engagement.
Can you support UK pharma companies with MHRA requirements?
Yes. UK pharma and life sciences Power BI use cases: clinical trial progress dashboards (Phase I–III enrolment, site performance vs. protocol targets), manufacturing quality (OEE, batch release rates, deviation tracking), supply chain (inventory days, distribution SLAs), and MHRA/ICH E6 GCP audit trail requirements. UK GDPR and EU GDPR dual-regime compliance for cross-border clinical datasets is standard — we document the SCCs where required.
Do you work with London law firms and consulting firms?
Yes. London professional services Power BI: billable hours and utilisation by partner/practice group, matter profitability (law firms — Elite, Aderant), project margin analysis (consulting — SAP PS, Microsoft Project), and WIP reporting for accountancy firms (CCH, Practice Engine). UK GDPR consent tracking for client personal data and UK Modern Slavery Act reporting data are recurring requirements we handle.
What London clients get on a Lets Viz engagement
Our Offerings
Financial services BI
Treasury dashboards, FCA regulatory reporting (PRA, Basel III capital monitoring), fund performance vs benchmark, and trade surveillance with Azure Anomaly Detector. Row-level security, audit logging, and data residency in Azure UK South.
How a London-based asset manager eliminated 5 days of manual regulatory reporting
An anonymised engagement — the same problem profile we see across FCA-regulated firms in the City and Canary Wharf.
The challenge
A London-based asset manager was producing PRA stress test reports and weekly NAV reconciliation across 7 Excel workbooks, pulling from a Bloomberg terminal, an in-house SQL database, and a third-party fund admin platform. Month-end reporting consumed 5 days of analyst time and the numbers still required a manual sign-off call between the risk and finance teams to reconcile.
What we built
We built a Power BI semantic model with Azure UK South data residency, connecting Bloomberg via API, the SQL warehouse, and the fund admin platform's SFTP export. Row-level security restricted portfolio views by analyst role. A dedicated FCA reporting view automatically formatted monthly submissions. The DPA and data flow documentation were delivered as part of the handoff.
Outcomes
5 days → 4 hrs
month-end regulatory reporting time
7 → 1
Excel workbooks replaced by one semantic model

GDPR-native, FCA-aware, GBP fixed pricing
London buyers evaluate Power BI consultants on three things: data governance posture, industry sector depth, and cost predictability. We have clear answers to all three.
UK GDPR and EU GDPR by design
We design for dual-regime compliance from the first data mapping session. Every engagement includes a DPA, documented lawful basis, and UK South Azure data residency. Not an afterthought — built in from line one.
FCA and financial services depth
We understand SYSC operational resilience requirements, PRA stress test data structures, and the FCA-authorised firm vendor onboarding process. We have delivered for asset managers and payment institutions.
Fixed GBP pricing — no open-ended day rates
All quotes are in GBP, fixed scope. No hourly billing surprises. Invoice via Stripe or bank transfer, VAT-registered if required.
GMT/BST working hours
Same-day responses on board presentations, investor reporting, and regulatory submissions. Full overlap with the London working day — not overnight turnarounds.
Are you looking for a Power BI consulting partner or a London contractor?
London buyers often search 'Power BI consultant' but mean different things. London contractor day rates run £400–£800 open-ended. Here is the actual distinction.
Consulting partner (Lets Viz)
- We own the outcome — model, pipeline, reports, governance documentation
- One named senior analyst accountable from kickoff to hand-off
- We define the approach and the data residency recommendation
- Deliverables include a DPA, data flow diagrams, and training
- 2-business-day SLA on managed retainers — we monitor proactively
- GDPR data mapping included — not billed separately
Staffing agency / body shop
- Places a contractor at your direction — you manage the work
- Open-ended day rate with no outcome accountability
- You own all project management and GDPR compliance work
- IR35 status risk to manage depending on engagement structure
- No monitoring, no SLA — broken pipelines found by your team
- Senior expertise not guaranteed — junior contractors common at senior rates
