Data Analysts in Cardiff earn a median £36,100 per year — 5% below the UK average for the role, led by the Cardiff insurance and Welsh Government employer base. The middle 50% of earners sit between £28,500 and £47,500, and senior practitioners with a strong specialism push past £74,100. Pay rises are typically banded by experience rather than annual increment, so the route to higher earnings is changing employer or stepping up a level — not waiting for a cost-of-living adjustment.

What separates a £26K developer from a £65K one in Cardiff

Beyond the headline numbers, the more useful question for engineers is what actually drives pay between bands.

The pay gap between a junior and a staff-level Data Analyst in Cardiff is essentially a gap in ownership. Juniors implement; mid-level engineers own a feature; seniors own a system; staff engineers shape what the team builds and why. The salary curve mirrors that — entry roles cluster around £24,700, mid-level pay lands close to the £36,100 median, and the upper quartile (£47,500) is where engineers sit who can be trusted to scope and lead a quarter of work without a manager rewriting it.

Three things move salary fastest in Cardiff: depth in SQL or Excel that's hard to hire for, a track record of shipping production systems (not side projects), and being credibly able to mentor others. Total comp matters too — the larger London-headquartered tech employers (and US firms with a Cardiff office) increasingly pay 15–30% of base in equity or RSUs, which doesn't show up in ONS figures. If you're benchmarking offers, ask for total comp, not just base.
