Before we dive in, here’s the best bit of advice we can give to would-be DIY electricians:
Don’t bother. Find yourself a qualified electrician here: NICEIC Find a Tradesperson
Understanding Electrical Regulations Yes, there are jobs you can legally do yourself, and we’ll cover those below. But before you start rewiring your kitchen because you “watched a video on YouTube”, remember: insurance companies aren’t your mates. If the socket you fitted causes a small fire, your insurer could have 101 reasons not to pay out.
That said, if you know your AC from your DC (great band, by the way) and just want a better grasp of what you’re allowed to do, read on.

Why These Regulations Matter
Electrical rules aren’t about red tape — they exist to keep you, your family, and your home safe from shocks, fires, and costly mistakes. The UK has a few big players who set and enforce these standards:
- The Institution of Engineering and Technology (IET) – authors of the famous BS 7671:2018 Wiring Regulations (aka the “wiring regs”).
- The Department for Levelling Up, Housing and Communities (DLUHC) – responsible for the Building Regulations, including Part P which covers electrical safety in homes.
- The Health and Safety Executive (HSE) – set health and safety standards and guidance for workplaces and homes.
Three Key Regulations You Should Know
1. BS 7671 Wiring Regulations
This is the safety bible. It covers everything from how circuits are designed, to earthing, to which cables are safe where. You don’t need to know every word, but you do need to know it exists — and that electricians are trained to work to it.
2. Part P of the Building Regulations
This one’s especially important for homeowners. It says that certain electrical work must either:
- Be carried out by a registered electrician, or
- Be notified to your local building control.
Think kitchens, bathrooms, new circuits, and extensions.
3. HSE Guidance
The HSE push two big things:
- Risk assessment – don’t just dive in with a screwdriver.
- Competency – only do work you’re genuinely capable of.
What You Can (and Can’t) Do as DIY
Generally safe for competent DIYers:
- Replacing like-for-like light switches and fittings.
- Swapping a broken socket outlet for a new one.
- Sockets paid link

Leave to the pros:
- Installing new circuits.
- Full or partial rewires.
- Anything in bathrooms, kitchens, or outdoors.
If in doubt, don’t chance it.
Spotting Trouble Before It Sparks
Keep an eye (and nose) out for these signs:
- Flickering lights = loose connections or overloading.
- Warm plugs/sockets = overheating and potential fire risk.
- Burning smell = serious danger → turn off the supply and call an electrician immediately.
In Case of Emergency
- Switch off at the consumer unit (fuse box).
- Don’t touch anything wet.
- If there’s fire risk → dial 999.
