Many homeowners wonder whether they can tackle electrical work themselves. The short answer is: some work, yes – but much of it should be left to professionals. Here's what you need to know.
The Legal Position
In England and Wales, there's no law that says only electricians can do electrical work. However, Part P of the Building Regulations requires that electrical work is safe and, for certain types of work, properly notified and certified.
Work You Can Do Yourself
The following work doesn't require notification (though it must still be done safely and correctly):
- Replacing light fittings (like-for-like)
- Replacing sockets and switches (like-for-like)
- Replacing a damaged cable section
- Adding a spur to an existing circuit (outside kitchens/bathrooms)
- Installing low-voltage lighting (e.g., garden lights)
- Replacing a fuse in a plug
Work That Requires Notification
This work must either be done by a registered electrician or notified to building control:
- Installing a new circuit
- Replacing the consumer unit
- Any work in a bathroom
- Any work in a kitchen involving new circuits
- Outdoor electrical installations
- Installing an electric vehicle charger
Why You Shouldn't DIY
Safety
Electricity kills. Even "simple" work can be dangerous if you don't know what you're doing. Mistakes can cause electric shock, fires, or create hidden hazards.
Insurance
If DIY electrical work causes a fire or injury, your home insurance may not cover you. Insurers expect electrical work to be done by competent people.
Selling Your Home
When you sell, buyers' solicitors ask for electrical certificates. Uncertified work can delay or prevent sales.
Getting It Wrong
Incorrect electrical work can create dangers that aren't immediately obvious – wrong cable sizes, missing protection, poor connections. These can cause problems years later.
The Cost Argument
People often consider DIY to save money. But consider:
- Professional work comes with certification and warranty
- Mistakes can be expensive to fix
- Your time has value
- The risk of injury or fire damage
- Potential insurance implications
For most electrical work, professional installation is worth the cost.
When to Call a Professional
- Any work you're not 100% confident about
- Anything involving the consumer unit
- New circuits or significant additions
- Work in bathrooms or kitchens
- Outdoor installations

Conclusion
While some minor electrical work is legally permissible as DIY, the risks often outweigh the savings. For anything beyond changing a light fitting or socket faceplate, consider using a qualified electrician. Your safety, your insurance, and your peace of mind are worth it.
