Data Scientist salary in London.

Data Scientist market in London.

The data science market in 2026 is bifurcated: traditional ML roles (model building, feature engineering, A/B testing infrastructure) have seen modest growth, while roles adjacent to large language models and generative AI are commanding a 20–40% premium. The practical implication for salary benchmarking is that 'data scientist' covers a wide band; the percentiles on this page reflect the median, which means AI-specialist data scientists at the 75th percentile or above will find the headline figure understates their market value. Contract rates for LLM-adjacent data science work in London run to £700–£950/day.

London specifically: London salaries are the highest in the UK and carry the largest cost-of-living adjustment. The London premium over the national median is roughly 15–30% depending on role. Remote-first employers have applied downward pressure on this premium, but in-office and hybrid roles in London still command a clear uplift. Contract day rates in London run 20–35% above equivalent Manchester or Birmingham figures.

Members in this role typically add £8,600/year.

Modeled on a conservative 4 hours/week of contract work at the role's implied hourly equivalent (£43/hr). The Hustle Report Monday editorial finds the briefs and ranks them by fit so the time stays small.
