Renewable Energy Companies Using Jetpack in the UK: 51 Active Firms (2026)
Renewable-energy businesses running web plugins publish, manage and measure public websites while operating in the UK energy market.
For renewable-energy operators, this plugin is usually a website-operations layer rather than a core energy platform. It supports publishing cadence, form capture, uptime and performance monitoring, spam control and basic audience measurement around project pages, customer tariffs, service contracts and investor material. Adoption tends to signal a direct-channel posture: marketing or operations teams want to adjust content without waiting for a full agency release cycle, while still keeping a relatively light technical stack. In this cohort, the buyer is more often commercial, operations or stakeholder-communications led than pure IT-led; engagements are typically small web retainers, plugin subscriptions and occasional build work rather than enterprise software programmes.

UK adoption is small but visible: 51 actively trading renewable-energy businesses are running the plugin on public websites. The employment footprint is modest, with 438 reported employees across the cohort. Within the sector’s detected website-plugin stack, the system sits second in the category ranking at 15.1% against a category base of 337. Registered-office locations are spread rather than London-only: Scotland accounts for 13.7%, London and the East of England each 11.8%, and the North West and South East each 9.8%. That mix fits a market made up of project developers, installers, asset operators and service firms as much as city-headquartered suppliers.
Companies that generate, move or supply energy in Great Britain operate inside Ofgem’s licensing framework, so public websites can carry compliance-adjacent material as well as sales copy: project information, customer notices, generation claims and investor updates all need internal owners. The Renewables Obligation is closed to new generating capacity, but accredited stations still face audit and compliance checks and submit generation information for certificates. For companies running this stack, procurement is therefore less about a regulated software purchase and more about controlling a public channel that intersects with licensing, consumer communication, planning scrutiny and renewable-support obligations.
Adoption appears likely to remain selective rather than universal. Renewable-energy firms with active project pipelines, consumer propositions or investor audiences tend to have more reason to keep website tooling in-house, while single-asset vehicles often have little need beyond a static presence. Agency-managed builds may persist where compliance review, planning content and stakeholder updates are bundled into wider communications work. Over time, the plugin may be absorbed into broader managed-site packages or displaced by simpler hosted tools, especially where lean teams value fewer maintenance tasks. The enduring users are likely to be operators that treat the website as an owned commercial and disclosure channel, not just a brochure.

How Jetpack usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling. Renewable energy companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of Renewable energy companies with a detectable system — not of all UK companies.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
Jetpack is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
