What Kewtech does

Kewtech Corporation Ltd is a UK-based, privately-held manufacturer of professional electrical test equipment, founded in 2004 and headquartered in Sunningdale, United Kingdom. The company designs and produces a comprehensive portfolio organised around four functional pillars: multifunction testers (MFTs) for BS7671 18th Edition installation testing, PAT testers for portable appliance testing, EV charge point testing adapters, and safe isolation kits for compliance with safe isolation procedures. Its flagship products include the KT66DL 12-in-1 MFT, the KT64DL marketed as 'the UK's smallest MFT', the SMARTPAT (described as the world's first Wi-Fi operated PAT tester), and the KEWEVA adapter which won 'Electrical Product of the Year 2024'. Underlying proprietary technology includes Anti-Trip Technology (ATT) for no-trip loop testing, single rotary-dial CP auto check on the KEWEVA, and automatic voltage detection regardless of battery status (KT5) for GS38-compliant safe isolation.

Kewtech monetises primarily through hardware sales, supplemented by a freemium software layer (the free KEWPAT app for PAT documentation and reporting, with integration to SimplyPats and Tradecert certification software) and a calibration/repair services business offered to both end users and wholesale partners. Pricing is quote-based with a dedicated trade price list for registered wholesalers; the company does not publish list pricing. Distribution is anchored in UK trade wholesalers and electrical distributors, complemented by direct e-commerce via kewtechcorp.com and a field calibration service operation. The company also distributes specialist instruments from Japanese manufacturer Kyoritsu through the same channel.

Kewtech's customer base consists primarily of small-to-mid electrical contractors and PAT testing professionals across the United Kingdom, with adjacent reach into gas engineers via the TB118 Kit and industrial end users via the lock-off and process clamp ranges. The company operates with 11-50 employees, holds no disclosed external funding, and has no identified parent company or institutional investors in the available source data. Marketing is product-led: an extensive YouTube video library, content marketing, Trustpilot reviews, trade events, and social channels support demand generation, while a calibration/repair service layer creates ongoing touchpoints beyond the initial hardware sale.

• Kyoritsu: Japanese manufacturer of electrical measuring instruments with overlapping product lines in MFTs, clamp meters and insulation testers. Notably, Kewtech is itself a UK distributor of Kyoritsu specialist instruments, making them both a partner and a direct competitor in adjacent SKUs.
• Martindale Electric: UK manufacturer focused on safe isolation, voltage detection and socket testing equipment. Overlaps directly with Kewtech's KEWISO safe isolation kits, KT voltage testers and LOOPCHECK socket testers.
• Megger: UK-headquartered manufacturer of electrical test equipment including multifunction testers, PAT testers and insulation testers. Directly competes with Kewtech's MFT and PAT portfolios in the UK contractor market and is the brand Kewtech is most often benchmarked against by customers.
• Chauvin Arnoux: French manufacturer of electrical test and measurement instruments (multifunction installation testers, clamp meters, insulation testers). Targets the same European electrical contractor customer base as Kewtech with comparable product categories.
• Seaward Electronic: UK-based specialist in PAT testing equipment and electrical safety testers, with the Apollo and Supernova ranges. Directly competes with Kewtech's EZYPAT and SMARTPAT lines for the PAT-testing professional segment in the UK.

Broad incumbents

• Testo SE & Co. KGaA: German-headquartered measurement technology company with broad offerings in electrical, environmental and HVAC instrumentation. Kewtech itself sells Testo-style environmental instruments (light, sound, temperature) and the two compete in adjacent measurement categories.
• Fluke Corporation: Global leader in professional electronic test and measurement tools with a broad portfolio of multimeters, clamp meters and installation testers. Kewtech explicitly references Fluke in switching-customer testimonials (e.g., Nexus Electrical) and competes with Fluke's installation testers in the UK.
