Data consultancy in London

Data consultancy in London that turns scattered data into decisions.

Clarity Business Intelligence is a data consultancy working with financial services, professional services, media, tech and public sector organisations across Greater London. We build data platforms, clean up reporting and give teams numbers they can trust, delivered remotely across the UK with on-site visits where they help.

London's economy is dominated by financial and professional services, but it also holds a vast base of technology firms, media companies, retailers, healthcare providers and public sector bodies, all generating data at a scale most regional businesses never see. The challenge in London is rarely a lack of data; it is too much of it spread across CRMs, finance platforms, marketing tools and legacy systems that were bought by different teams at different times and never designed to work together.

We work with organisations across every sector in London, including financial services, retail, professional services, healthcare, logistics, charities and the public sector. We do not restrict ourselves to a single industry, because the same problem repeats everywhere: reporting that takes days to produce and still leaves people arguing over whose numbers are correct.

Data consultancy services for London businesses

Data engineering and warehousing

We design pipelines that pull data from finance systems, CRMs, e-commerce platforms and internal databases into a single warehouse, so London teams stop rebuilding the same exports every month.

Data modelling

Our data modelling services give large, complex datasets a clear structure, which matters most in London where businesses often run several product lines or entities under one group.

Power BI reporting and dashboard design

Through Power BI consultancy and dashboard design we build reporting that gives leadership teams a single view of performance across departments, without every division building its own version of the truth.

Data visualisation

Our approach to data visualisation strips out clutter so senior stakeholders can see what matters in seconds, rather than wading through slide decks before a board meeting.

Analytics and forecasting

Through data analytics services we help London businesses forecast revenue, churn and demand, using statistical methods as the default and machine learning only where the data volume and quality genuinely support it.

Microsoft Fabric

Our Microsoft Fabric consultancy helps London organisations consolidate the patchwork of reporting tools that tends to build up in larger businesses, bringing data engineering, warehousing and reporting under one Microsoft platform.

Data governance and data quality

Through data governance consulting and data quality management we set clear ownership for each dataset, which is essential once several departments in a London business rely on the same customer or product records.

Data migration

Our data migration services support moves to new finance, CRM or ERP systems, keeping historical reporting intact through the transition rather than leaving a gap in trend data.

Master data management

Our master data management work gives London businesses a single trusted version of customer, product and supplier data, so different teams stop working from conflicting lists.

Training and ongoing support

Once a solution is live we offer Power BI training so staff can build and maintain their own reports, backed by ongoing support as requirements change.

How we work with London businesses

We start with a discovery conversation to understand your systems, priorities and current pain points, then agree a fixed price for a first phase of work, typically a data model and one working report, so you can see value before committing further. Build work happens remotely, with onsite visits to London for workshops and handover where that helps the project move faster.

As part of a wider UK data consultancy serving businesses nationwide, we deliver most work remotely and visit London on site where it is practical to do so. Get in touch to talk through what you need.
