PV Installation Companies Using Wix in the UK: 170 Active Firms (2026)
PV installation companies using hosted website-builder features design, quote and present solar projects for UK households and businesses.
Hosted site-builder adoption in PV installation tends to sit in the sales and operations layer rather than in engineering delivery. The system gives small and lower mid-market installers a low-maintenance way to publish project pages, answer household and commercial buyer questions, capture quote requests and route bookings or document downloads. Use of this stack usually signals a direct-channel posture: the firm expects prospects to self-educate online before a site survey or energy assessment, but may not yet have the internal web team or custom development budget associated with larger installation groups.

Across the UK, 170 actively trading PV installation companies run this hosted site-builder. Reported employment across the cohort totals 1,090 people, which fits a market led by small installation teams rather than enterprise-scale energy groups. Within the sector’s 1,386 detected CMS sites, the system ranks second, with a 12.3% share; the main alternative accounts for 74.2%, so adoption remains a minority pattern. The regional skew is not especially London-centric: East of England accounts for 16.5%, South West 14.1%, South East 12.4%, London 11.8% and West Midlands 10.0%.
Procurement and compliance issues sit around the installer’s web journey rather than the site-builder itself. PV buyers are asked to submit service addresses, project details and contact data before a quotation, so consent wording, form handling and document retention matter. The surrounding stack tends to include forms, analytics, page widgets and visual enhancements, typical of owner-managed service businesses using modular tools. Claims about savings, installation suitability and eligibility for support need care, because the website often frames the commercial conversation before any surveyor has checked the property.
Adoption appears likely to remain concentrated among installers that want a controlled brochure, enquiry and education channel without maintaining a custom web build. As firms add financing referrals, monitoring portals, aftercare workflows and partner-led fulfilment, some will outgrow hosted templates and move towards more integrated marketing and operations systems. Others will keep the lighter stack because it suits local search, seasonal campaign pages and quick updates to services. Consolidation among installers would tend to favour standardised platforms, but the long tail of small operators should keep hosted builders in regular use.
Adoption by company size
Adoption of Wix varies by company size across the trading UK PV installation companies in this cohort. 10.8% of the 1,213 companies with under 10 employees run Wix (131 detected). 8.8% of the 410 companies with 10–50 employees run Wix (36 detected). 3.3% of the 30 companies with over 50 employees run Wix (1 detected). That is a 7.500000000000001% gap between the over 50 employees and under 10 employees bands.

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. PV installation 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 PV installation 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.
Wix is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
