The internet is full of DIY instruction videos but, even if they claim to be experts, online DIYers don’t always know their stuff, especially where electrics are involved.

Don’t put your life at risk by following advice from YouTube DIYers.

Back in 2016, we conducted research with almost 1,000 electricians about their experiences fixing DIY projects.

One-third had seen electric shocks caused by botched DIY.

15% reported the DIY had caused an electrical fire.

The most common mistakes that people make when attempting to undertake DIY tasks were cutting through power leads, drilling into wiring, and trying to repair an electrical item while it is still switched on.

Many people take on projects that should be left to experts, often driven by tutorials found on the likes of TikTok, Pinterest, Instagram, and YouTube.

Although there are undoubtedly some jobs people can do themselves, it is important to be aware of any potential electrical risks before starting DIY.

And any electrical repairs should be left to the professionals. While the internet is a great resource, it’s no substitute for the real thing – a professional who can do the job safely and effectively.

Never follow online DIY advice if you’re not 100% confident it’s been provided by a fully qualified, competent person.

And if you're unsure about potential electrical risks, seek advice from a registered electrician. 

1. Locate cables in your wall. A common DIY error is accidentally drilling, nailing, or screwing into cables hidden inside your walls. A quality cable detector can help track buried cables before you start work and reduce the risk of an electric shock.
2. Use an RCD (residual current device). An RCD can save your life by cutting off the power in the event of an electrical fault caused by a DIY blunder. Make sure you have an RCD fitted in your fusebox (consumer unit) and, where necessary, use a plug-in RCD.
3. Shut off the power. If you're doing any work near electrical wiring or power supplies, it is recommended to shut off the power in your fusebox (if you can) and only use battery-powered tools. To be sure that power is off before beginning DIY, plug an appliance into sockets or try switching on the lights.
4. Before using power tools, check the lead and plug. If you see signs of damage (for example, frayed wires) get the equipment professionally repaired before using it, or get it replaced. Watch out for the power lead at all times so you don't accidentally cut through or trip over it.
5. Get advice from a registered electrician. The best way to avoid electrical accidents in the home is to seek the advice of a professional. And, if you’re not sure, don't DIY.

If you need any electrical work done in your home, don't do it yourself. The best option is always to get a competent person to do the job.

Find a registered electrician

Part P of the Building Regulations is the legal framework that covers householders who are having work done in their homes.

It states that work which is deemed more dangerous – such as in the bathroom, or the installation of a new circuit – must be undertaken or reviewed and signed off by a registered electrician.

A lot of electrical work in the home is "notifiable" meaning that by law the local authority has to be informed of it and it has to be certified by a registered electrician.
