The 10 best gas leak detectors to buy in the UK

Picture of a gas leak detector

Whether you are professionally dealing with gas or someone at home using gas appliances, it is always worth having the best gas leak detector possible. After all, when living in a gas-powered house or working around with gas, there is a huge risk of gas leaks that are highly dangerous, so by having the best detectors possible you can find the problem quickly and take appropriate action.

But exactly can you expect from the best gas leak detectors? Check out the buying guide below for all the information you need to know to find the right gas sniffer.

What are gas leak detectors?

As the name suggests, a gas leak detector is a device that is used to detect possible gas leaks. Used in homes and commercial properties, this device uses a sensor to detect the presence of unwanted gas and provide a warning should any be found, usually in the form of an audio or visual alarm.

Why should you buy a good gas leak detector?

Many gases are harmful to people but difficult to detect due to being odourless. For example, carbon monoxide can occur while burning natural gas to heat homes and this gas is both odourless and colourless. So if leaked you can’t detect it and could possibly die from carbon monoxide poisoning. With the best gas leak detector, you can rest easy knowing that any gas leaks that happen in your home or workplace can be easily detected using the gas detection device. This could literally save lives, making it an essential buy for anyone that lives in a gas-powered home or works around gas.

How to choose the right gas leak detector in 2024?

Given how important the device is for your personal safety, it makes sense that you want to choose the best gas detector possible. Here are some things to think about that can make this process easier:

  • Gas Type: Some gas detectors only detect a single type of gas while others can detect many. So identify what gas types you are dealing with so that you can choose an appropriate detector. For example, in a gas-powered home you have to deal with natural gas and carbon monoxide, so the device should be able to detect these.
  • Sensitivity: Detector sensitivity is typically measured in parts per million, so make sure that the device can detect an appropriate amount of gas. For example, carbon monoxide leaks often see smaller volumes of gas that are undetectable unless a good gas leak detector has lower sensitivity. These can still be lethal over time, yet the device may not recognise the presence until it becomes more concentrated.
  • Portability: Gas leak detectors are available as both fixed and portable devices, either of which may be preferable to your situation. For example, if you only need to detect gas at home a fixed detector in each room may suffice, while mechanics, technicians, and engineers working with gases in their job will require a portable device.

What is the best kind of gas leak detector in the UK?

Here are the main types of popular gas leak detectors available to buy:

  • Fixed Gas Leak Detectors: This gas sniffer is fixed in place to provide continual protection against leaks. These are probably the best type of gas leak detector for homes as they can be left on their own to detect any leaks, notifying you via alarm should any be found.
  • Portable Gas Leak Detectors: These handheld detectors are portable for use around the home or worksite. Powered by batteries, they are better for people that need to check for leaks in multiple rooms, so are the best detector for technicians and engineers working on site.
