Renewable Energy Companies Using Wix in the UK: 293 Active Firms (2026)
Renewable-energy businesses running a hosted web platform generate, develop or support low-carbon power across the UK.
For renewable-energy operators, a hosted website-building platform usually sits at the commercial edge rather than the operational core. It handles project pages, grant or scheme explainers, local-service enquiries, recruitment, event listings and document publishing for buyers that may include landlords, facilities teams, local authorities and infrastructure partners. Adoption tends to signal a marketing-led posture: enough budget for a maintained web presence, but not necessarily a large digital engineering team. In this cohort, the pattern points to scaling SMEs and mid-market operators rather than enterprise utilities, with the site used to turn technical credibility, compliance material and regional coverage into inbound enquiries.

UK adoption covers 293 renewable-energy businesses in this list, all actively trading and running the platform on their public websites. Reported employment stands at 1,299 people. The platform ranks second among detected CMS options in the sector at 10.4% of 2,825 renewable-energy sites; the first-ranked system accounts for 71.8%. Registered-office skew is broad rather than purely London-based: London accounts for 16.4%, followed by the East of England at 13.7%, the South West at 11.6%, the South East at 10.6% and the East Midlands at 9.9%.
Great Britain’s licensed energy activities bring a different operating context from ordinary local-services websites. Renewable-energy businesses that generate, move or supply energy need Ofgem permissions and must comply with standard and any special licence conditions once granted. For operators with accredited legacy assets, the Renewables Obligation remains relevant even though it is closed to new generating capacity: generation records, audit trails and certificate submissions still have to be managed. Public-sector and infrastructure customers also tend to expect clear online evidence of accreditations, safety documentation and delivery scope, so the website often acts as a procurement support layer rather than only a brochure.
Adoption appears likely to remain concentrated among owner-managed installers, project developers and service businesses that value speed of publishing over bespoke engineering. As renewable-energy buyers ask for clearer evidence on delivery capability, maintenance cover and compliance, hosted sites may carry more gated documents, project updates and enquiry-routing functions. Some maturing operators will outgrow the platform as tender pipelines, multilingual content or integration needs become more complex. Others will stay, particularly where the website is mainly a trust signal for regional origination rather than a transaction system. Consolidation in the sector may also leave a tail of dormant or lightly maintained sites after acquisitions.

How Wix 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.
