What Big Clean Switch does
Big Clean Switch (trading as Brakkn Ltd) is a UK-based, B Corporation-certified energy switching platform founded in 2016 in Bournemouth. It operates a dual B2C/B2B model helping UK households, employers, and organisations identify and switch to renewable electricity tariffs from a curated panel of green suppliers (Octopus, Bulb, Ecotricity, Good Energy, People's Energy, So Energy, Co-op Energy) while explicitly excluding fossil and large-scale biofuel tariffs to avoid greenwashing. The May 2021 merger of Clean Energy UK into Big Clean Switch unified the consumer switching brand with the business energy brokerage, giving the firm a single brand across households, SMEs, NGOs, and large employers.
The technology stack is a customer-facing comparison and engagement platform layered onto third-party integrations: price comparison is delivered via MyUtilityGenius Ltd; smart meter data (30-minute interval) is collected and stored via N3RGY DATA LIMITED; appliance-level energy disaggregation analysis is delivered through a partnership with ONZO Limited / Green Energy Options Limited; and the website chat layer is provided by Crisp on top of Cloudflare's CDN. Core product lines include a Home Energy Switching Service, a Business Energy Procurement brokerage, an Employee Energy Support benefit program priced at £1.20 per employee per year, an Energy Attribute Certificates offering for corporate ESG reporting, an Energy Helper guidance tool, and an Ethical Perks discount module.
Monetisation combines transaction-based commissions from energy suppliers when customers switch (the primary revenue stream on the consumer side) with a low-ticket, high-volume subscription model for the B2B2C Employee Energy Support channel where employers act as distribution anchors. Customer acquisition blends SEO/content marketing, Google and Facebook paid media, and a channel-led approach through employer partnerships (IKEA, Tesco, Sky, Burberry, Nandos, Ben & Jerry's, Brompton, JLL, Hitachi, GoCardless, Barratt, Bloomsbury, GMCA, ISEP, Abel & Cole, Orbit). The company remains privately held, single-jurisdiction (UK), and operates with a 1-10 employee footprint.

Big Clean Switch competitors and assessment
Company assessmentBroad incumbents
- uSwitch: UK-based broad price comparison platform covering energy, broadband, insurance and more, directly serving the same consumer-switching use case as Big Clean Switch but without a green-only positioning.
- MoneySupermarket: Mass-market UK comparison marketplace across energy and financial products; competes for the same household switching traffic that BCS targets, including green tariffs.
- Compare the Market: Large UK price comparison brand with a substantial energy switching vertical, competing head-to-head with BCS for consumer-side traffic and supplier commissions.
- GoCompare: UK price comparison site with a strong energy comparison vertical; competes with BCS for switcher traffic and acquisition via search and brand marketing.
Direct peers
- Look After My Bills: UK auto-switching energy service that automatically moves customers to better tariffs; overlaps directly with BCS on consumer energy switching and brokerage commissions.
- Selectra: UK and European energy price comparison and switching service operating in a similar intermediary/broker model, with growing focus on green energy offers.
- Econnect Energy: UK-based energy broker focused on renewable and corporate energy procurement; competes with BCS's B2B business energy procurement and Energy Attribute Certificate offerings.
Others
- Octopus Energy: Direct green energy supplier and key BCS supply partner; competitive because Octopus's own consumer switching tools and tariffs reduce reliance on intermediary platforms like BCS.
Emerging players
- Evergreen (ethical energy switching): UK green-only energy switching service operating in the same niche anti-greenwashing positioning as Big Clean Switch for environmentally minded households.
- Salary Finance: UK employer-sponsored financial wellbeing platform offering employee benefits including energy support; overlaps with BCS's employee energy support channel for distribution via employer partners.
