Renewable Energy Companies Using Squarespace in the UK: 158 Active Firms (2026)
Renewable-energy businesses running hosted site-builder storefronts generate, install or advise on low-carbon power across the UK.
For renewable-energy operators, a hosted site-builder is usually a front-office system rather than a core energy platform: it handles explanations of installations, project credentials, appointment requests, quote forms and small-catalogue equipment sales. Adoption tends to signal a small commercial or owner-led marketing function, with enough budget for paid acquisition and analytics but not necessarily a custom web team. The buying centres are usually sales, operations and founder management, not IT procurement. Most engagement patterns look like local or regional lead generation for installers, advisory work and development pipelines, with public-sector and business buyers needing clearer credentials than a simple consumer brochure site.

UK adoption among renewable-energy businesses is a small slice of the sector’s web stack: 158 actively trading companies run the hosted site-builder. It sits third in detected CMS share within the sector, at 5.6% of a sector CMS comparison denominator of 2,825, behind a much wider self-hosted CMS pattern and another hosted builder. Reported employment across the cohort is 1,222 staff, with 112 of 112 firms reporting headcount (100%). Registered office skew is spread rather than London-only: South East accounts for 15.2%, London 13.3%, Scotland 12.7%, South West 12.7% and East Midlands 8.9%.
Energy activity, not the website software, drives the main compliance burden. Businesses that generate, move or supply energy in Great Britain need the relevant Ofgem licence and must comply with standard and special licence conditions once granted. Renewable-support administration also matters for accredited generation: the Renewables Obligation is closed to new capacity, but stations already accredited remain subject to audit, certificate and generation-reporting duties. For companies running a hosted builder, procurement risk is more about contact-form handling, analytics consent, evidence of claims and hand-off into sales or operations systems than about the web platform being energy-regulated.
Adoption appears likely to remain pragmatic rather than strategic. Renewable installers and advisers with owner-led marketing teams tend to value fast publishing, quote capture and tidy service pages, while larger generators and energy suppliers are more likely to move towards custom stacks, tighter consent controls and deeper CRM integration. The sector’s early-commercial weight points to churn between low-code builders as firms rework offers, add financing or product catalogues, and professionalise bid materials. Compliance pressure around claims, customer communications and evidence trails should keep the website close to sales operations, even when the core energy systems sit elsewhere.

Key facts
About 6% of the trading cohort reports turnover above £5M (10 of 158 firms) — the rest sits below that revenue band.
14% of the cohort was incorporated since 2022 (23 firms), so a sizeable share is in its first few filing cycles.
Within renewable-energy companies with a detectable CMS, the hosted site-builder sits third by detected share at 5.6% (158 of 2,825), behind the two largest systems at 71.8% and 10.4%.
The cohort is most concentrated in the South East at 15.2% (24), followed by London at 13.3% (21), Scotland at 12.7% (20) and the South West at 12.7% (20).
Co-detected marketing instrumentation is modest: 30.4% (48) show a web-analytics tag, 15.8% (25) a tag-management layer and 7.6% (12) paid-search advertising tags.
Overlapping sector tags point to installer and services exposure: 38.0% (60) also sit in field services and trades, 12.7% (20) in utilities and 12.0% (19) in construction.
Renewable-energy businesses that generate, move or supply energy in Great Britain need an Ofgem licence and must comply with standard and any special licence conditions once granted.

How Squarespace 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.
