Industry landscapes
The companies, capital and talent shaping energy tech in London. Find the leaders. Understand the segments. See where the activity is.
An industry ecosystem,
measured in context.
24 featured companies from the funding, hiring, revenue and team-size leaderboards.
Locked revenue figures are available in Radar; the eight company financial previews stay the same throughout this page. A dash means the figure is outside these featured lists. Revenue years vary by company; the figures are not a like-for-like revenue comparison. Compare annual accounts ↗
Recently founded means a recorded 2023–2026 founding year and no recorded parent, acquirer or public-company status. These companies are not labelled startups without that separate classification.

A company can carry several segment tags, so these rows overlap and should not be added together. Trend lines are zero-based and share one quarter grid, so a flat line is a quiet segment, not a missing one.
New apps published, beside apps whose most recent update landed in that quarter — the second bar is how much of the shelf is still being maintained.
Darker bars are new releases, lighter bars apps updated. 161 of 180 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

Institution and researcher rankings use citations to their covered work. Research scope: worldwide. This may be broader than the company geography.
Clear definitions for making better comparisons.
It measures the tracked company ecosystem, recorded funding, hiring and other available evidence. It is not a market-size estimate.
No. A company can belong to several segments, so segment counts and funding can overlap.
A dash or unavailable panel means the current reviewed source snapshot does not support that figure.
Company ecosystem snapshot: 2 September 2026. Funding is recorded in USD; filed accounts retain their stated currency and reporting basis. Each section identifies its own coverage. The news and research behind these sections is explorable in Prism.
