How does environment tech compare?
Each pair uses the same year, currency and reporting basis. Cohort overlap is disclosed.
| Industry | Covered / eligible | Revenue total | Median revenue | Net profit / loss | Aggregate margin | Profitable share | Overlap |
|---|
Available-account cohorts are not estimates of whole industries. Overlapping entities can occur in more than one cohort; do not add cohort totals.
Coverage, calculations & financial sources
Filed annual accounts for exact designated national identifiers. Every aggregate and peer pair uses one fiscal year, source currency and reporting basis; periods, coverage and overlap are explicit; 2026 partials are excluded.
The same up to eight reporting entities remain open across years, filters and sorts. Other company figures are available in Radar.
Source currencies and accounting bases stay separate. Missing accounts are excluded rather than treated as zero. Exact reporting periods appear on company previews. Annual totals can change with coverage and do not measure growth of a fixed company cohort.
Web traffic, app reach and release cadence
How the London companies on this page show up online: the sites people visit, the apps they install, and how often those apps ship.

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.
Release cadence by quarter
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. 144 of 160 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

Where demand signals run ahead of mapped supply — London
Compare demand signals in London’s newsflow with the environment tech categories mapped to each signal.
Signal percentile − supply percentile = gap in percentile points. Positive gaps highlight questions to investigate. A high signal can reflect spending pressure or access friction, as well as potential demand.
The comparison is relative to the signal families on this page. A supply percentile of zero means the lowest relative reading, not zero companies. It is a prioritisation clue, not measured market size or unmet demand.

Environment Tech in London: key questions
Clear definitions for making better comparisons.
What does this landscape measure?
It measures the tracked company ecosystem, recorded funding, hiring and other available evidence. It is not a market-size estimate.
Can segment counts be added together?
No. A company can belong to several segments, so segment counts and funding can overlap.
What does a missing figure mean?
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.
