PV Installation Companies Using RankMath SEO in the UK: 100 Active Firms (2026)
PV installation firms using SEO tooling design, fit and maintain solar power systems while signalling investment in search-led customer acquisition across the UK.
For PV installers, this kind of SEO plugin sits in the commercial website rather than in the installation workflow. It manages search titles, structured snippets, indexation rules and content hygiene across service pages, project pages and local landing pages. Running it usually signals a contractor with a direct enquiry channel, a maintained content-management site and some budget for agency or in-house marketing support. The fit is especially visible among firms trying to win residential and commercial solar leads without relying only on tender portals, referrals or paid advertising. It also implies a need to keep technical web changes aligned with changing offers, coverage areas and aftercare propositions.

UK adoption is still a minority pattern inside PV installation search tooling. The cohort comprises 100 actively trading PV installation firms running this SEO system, with reported headcount of 1,041 between them. Within 667 PV installers with an identified SEO tool, it ranks second at 15.0%, behind one higher-share plugin category at 76.0% and ahead of the next alternative at 7.6%. The registered-region skew is western and northern: South West accounts for 18.0%, North West 12.0%, South East 11.0%, with East of England and West Midlands at 9.0% each.
Search tooling sits close to quotation forms, call-tracking journeys and local landing pages, so adoption brings routine compliance work as well as marketing benefit. Domestic solar enquiries can include names, addresses and project information; privacy and electronic-marketing obligations make consent, retention and processor contracts relevant even where the installer is a small contractor. Procurement is usually web-agency led rather than enterprise IT-led, with plugin choice shaped by the site build and hosting stack. That creates some operational dependency on external developers when search templates, redirects or consent settings need changing after offer updates, coverage-area changes or aftercare-page revisions.
Adoption appears sticky while installer websites remain content-managed and agency-maintained. The cohort tends to look commercially practical rather than experimental: quotation-led pages, service-area content, case-study libraries and maintenance information matter more than elaborate brand campaigns. Pressure may come from search result layout changes, paid-lead costs and consumer scrutiny of energy claims, pushing installers to keep technical SEO, review signals and consent handling in better order. Smaller firms may stay with agency-selected defaults, while more scaled contractors are more likely to treat search infrastructure as part of their sales operations.
Adoption by company size
Adoption of RankMath SEO rises with company size across the trading UK PV installation companies in this cohort. 5.1% of the 1,213 companies with under 10 employees run RankMath SEO (62 detected). 6.8% of the 410 companies with 10–50 employees run RankMath SEO (28 detected). 16.7% of the 30 companies with over 50 employees run RankMath SEO (5 detected). That is a 11.6% gap between the over 50 employees and under 10 employees bands.

How RankMath SEO 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.
RankMath SEO is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
