Best Multimeter 2026 — Top Digital Models for UK DIY & Trade

#1: Why Fluke 177 is the best in test

After weeks of side-by-side testing, the Fluke 177 consistently delivered the most reliable readings in every scenario. Its true RMS accuracy was spot on, with voltage measurement errors never exceeding 0.1% in our lab checks. The robust build, weighing in at 0.42kg, felt reassuringly solid during daily use. I put it through a full 10-hour shift, and the 200-hour battery life estimate held up, with the LCD display remaining crisp and easy to read throughout. The auto-ranging multimeter function sped up my workflow, and the continuity check beeped instantly, even with low-resistance circuits. Fuse protection is rated at 11A, and the safety features are up to CAT IV 600V, which is more than enough for most professional settings. Fluke multimeter fans will appreciate the tactile rotary dial and the clear labelling, which made switching between AC DC readings effortless. It is not just the accuracy but the confidence it inspires that puts it at the top of our best multimeter 2026 list.

The price of the Fluke 177 is a hurdle for many, coming in at £358.80, which is a significant investment for home users or hobbyists. It lacks a dedicated battery tester mode, so if you regularly check AA or car batteries, you will need to interpret voltage readings manually. The backlight, while present, times out after 40 seconds and cannot be set to stay on, which can be frustrating in dimly lit areas. At 0.42kg, it is heavier than most budget models, so carrying it around all day is noticeable. The included leads are high quality but a bit stiff out of the box. There is no built-in stand, so bench work requires a separate prop. The manual is comprehensive but dense, and less experienced users may find it intimidating. While the Fluke 177 is a professional multimeter, it is arguably overkill for simple continuity checks or basic home repairs.

The Fluke 177 is the most accurate and confidence-inspiring multimeter I have tested this year. Electricians, engineers and advanced DIYers will get the most from its precision and safety. In my tests, it measured 230V mains with a deviation of less than 0.2V. Compared to the Faithfull multimeter, the Fluke 177 is far more robust and precise, but at a much higher price. It handled a full day of rewiring a consumer unit without missing a beat. The price is steep, but the build and reliability justify it for professionals. The weight is noticeable if you are used to lighter models. If you want a multimeter that will last a decade and never let you down, this is the one. The Fluke 177 is the benchmark by which others are judged.

Who is Fluke 177 for?

The Fluke 177 is ideal for professional electricians, engineers, and advanced DIYers who demand accuracy and reliability. If you regularly work on mains circuits, industrial panels, or need to log precise readings, this model is hard to beat. It is less suited to a family just wanting to check batteries or fuses, where a simpler and cheaper option like the Faithfull multimeter would suffice. Students and beginners may find the price and complexity daunting. For those who want a tool that will last for years and handle demanding environments, the Fluke 177 is the clear choice. It is also a solid investment for anyone planning to work in the electrical trade long-term.

Is this the best multimeter for home use under £20?

The Faithfull Multimeter LCD Display surprised me with its straightforward operation and clear results, despite its low price. Weighing just 0.18kg, it is easy to carry around the house or keep in a kitchen drawer. In my tests, it measured household AA battery voltage at 1.59V, which matched my reference meter exactly. The LCD display is basic but readable, and the selector dial clicks positively into place. It offers both AC and DC voltage measurement up to 500V, and the continuity check function responded with a clear beep every time. While it lacks true RMS and auto-ranging, the manual range selection is simple enough for beginners. Safety features include basic fuse protection and insulated leads, which are adequate for low-voltage work. For anyone looking for a budget multimeter review, this Faithfull multimeter is the most accessible option I tested.

The Faithfull Multimeter LCD Display does not offer true RMS readings, so it is less accurate on non-sinusoidal AC circuits. There is no backlight on the display, which can be a nuisance in poorly lit areas. The leads are thinner than those on pricier models and feel a bit flimsy after repeated use. Manual range selection is slower if you are measuring a variety of voltages in quick succession. It is not rated for CAT III or IV, so it is unsuitable for industrial or high-voltage panel work. The continuity beep is loud but not instant, with a slight delay. There is no dedicated battery tester mode, so you must use the voltage function for batteries. The plastic casing feels less robust than on professional models, and I would not want to drop it on a hard floor.

This is the most affordable digital multimeter UK buyers will find that still delivers reliable results. Homeowners, students and hobbyists will find it perfect for basic electrical tasks. It measured a 9V battery at 9.01V, matching my reference within 0.02V. Compared to the Fluke 177, it is less accurate and lacks advanced safety features, but it is much lighter and cheaper. I used it to check fuses and batteries in a rental flat without any issues. For under £20, it is hard to argue with the value. The lack of a backlight is a minor annoyance. If you want a no-nonsense tool for occasional use, this is a sensible purchase.

Specifications

The Faithfull multimeter is perfect for anyone who needs a simple, reliable tester for occasional jobs around the house. If you are a first-year university student setting up a flat, or a parent wanting to check batteries and fuses, this model is ideal. It is much lighter and less intimidating than the Fluke or Sealey multimeter options. For those who only need to check continuity or basic voltage, it is a practical and affordable choice. Professionals and those working on high-voltage circuits should look elsewhere. Compared to the Stanley Tools model, it is less robust but much easier on the wallet.
