18th Edition MFT and EV Range
Testing electrical installations safely and accurately is essential for compliance and peace of mind. At CM Electrical, our 18th Edition MFT (multifunction testers) and EV test equipment range is built for electricians and installers working to meet the latest IET Wiring Regulations.
Whether you're certifying new installations, conducting periodic inspections, or testing electric vehicle charging points, we supply tools that help you carry out your work with precision. Each tester in this range supports 18th Edition testing requirements and is designed for day-to-day reliability on site.
We stock leading brands known for professional-grade build quality and ease of use. Our range includes standard multifunction testers and specialist kits for EV installation testing. Each product is selected for accuracy, clear display, and the ability to test a variety of systems, including RCDs, loop impedance, insulation resistance and continuity.
Built for Compliance and Reliability
With the 18th Edition wiring regulations now standard across the UK, it’s vital that your test equipment is up to date. Our range is designed to help you:
● Confirm compliance with current wiring standards
● Test all necessary circuits, sockets and RCDs quickly
● Accurately check new EV charging installations
● Store and recall test data where supported
Whether you're working in domestic, commercial or EV-specific installations, having the right equipment ensures work is safe, professional, and fully documented.
Applications of MFT and EV Testers
● Final circuit and RCD testing
● Zs and Ze loop measurements
● Insulation and continuity checks
● EV charge point testing including PEN fault detection (on compatible models)
● Earth resistance and PSC testing
Our testers are compact, durable, and ideal for day-to-day fieldwork.
Key Features to Look For
● Clear digital displays
● Auto-start or auto-ranging features
● Rechargeable battery options
● Bluetooth or USB data transfer (on selected models)
● Dedicated EV testing modes (where applicable)
Choosing the Right Tester
Not all testers offer the same functionality. If you’re focusing primarily on EV installations, look for models with dedicated EV testing modes and accessories. If you need a general-purpose tool for wider inspection and testing, a standard 18th Edition MFT with auto-ranging and loop impedance features may be a better fit.
If you're unsure, feel free to contact our team for advice before purchasing.
