Companies Using POWR in London: 457 Active Firms (2026)
Companies using website widgets in London embed form, popup, review or commerce features on public websites across the capital.
Front-end widget adoption tends to sit with marketing, ecommerce and web operations teams, rather than with a central software-buying committee. The job is usually practical: add lead capture, reviews, promotions or small commerce features without asking developers to rebuild the site. The London cohort looks more owner-managed than enterprise-led, with median turnover of £503k and median headcount of 7 among companies where those measures are reported. Running this kind of stack usually signals a public acquisition funnel, some consent-management overhead, and a preference for configurable tools over bespoke web development.

London accounts for 457 actively trading companies running this widget stack. Companies with reported headcount employ 2,108 people in total. The mix points to adoption by small commercial organisations rather than a narrow enterprise software estate: 18 firms have turnover above £5M, while 35 were incorporated since 2022. Sector overlap is broad, with education and training, travel and hospitality, construction, fashion and retail, and field services all represented, which fits a toolset used for public-facing conversion and engagement rather than one vertical workflow.
Embedded website tools sit inside the ICO’s privacy and electronic-communications perimeter when they store information on, or access information from, a visitor’s device. PECR regulation 6 covers cookies and comparable technologies, so analytics, marketing and third-party engagement functions generally need clear information and valid consent unless they are strictly necessary. UK GDPR and the Data Protection Act 2018 apply where personal data is processed. The Data (Use and Access) Act 2025 changed parts of the UK data and PECR regime, including cookie-consent rules and penalties, which makes supplier settings and consent banners a live procurement issue rather than a continuing legal task.
Adoption appears tied to the continued preference for low-code website estates, especially among commercial teams that want to change lead-capture and engagement journeys without waiting for a full development cycle. That pattern can persist, but it also creates review pressure: consent settings, script loading, page performance and supplier permissions tend to become more visible as firms mature. Some users are likely to consolidate widgets into broader website or commerce platforms, while others keep lighter embedded tools where the website remains the main sales or enquiry channel.
Adoption by company size
Adoption of POWR rises with company size across the trading companies in this cohort. 0.1% of the 532,485 companies with under 10 employees run POWR (303 detected). 0.9% of the 15,364 companies with 10–50 employees run POWR (145 detected). 0.9% of the 1,763 companies with over 50 employees run POWR (16 detected). That is a 0.8% gap between the over 50 employees and under 10 employees bands.

Key facts
About 3% of the trading cohort reports turnover above £5M (18 of 457 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (35 firms), so a sizeable share is in its first few filing cycles.
A website-building platform is also detected for 90.2% (412) of the London users, suggesting the widget is commonly layered onto hosted site infrastructure rather than custom builds.
Education & Training accounts for 12.5% (57) of the cohort, followed by Travel & Hospitality at 10.9% (50), with sector tags allowed to overlap.
Financial-health scoring is split: 20.8% (95) sit in the weak band and 5.9% (27) in the distressed band, while 3.7% (17) lack enough history for a score.
ICO guidance says PECR regulation 6 applies not only to cookies but to any technology that stores information on, or accesses information from, a user’s device; non-essential embedded tools require clear information and valid consent.
DSIT estimated the UK Digital Sector at £177.2 billion in current-price GVA in 2024, equal to 6.8% of total UK GVA.

How POWR 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.
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.
