Is it illegal to have no RCD protection – Advice from Electriman, North London Electricians

Is It Illegal to Have No RCD Protection in Your Home?

The short answer is: not automatically illegal for existing homes, but it is a serious safety issue — and for landlords or new work, the rules are much stricter.

What Is an RCD?

An RCD (Residual Current Device) is a life-saving safety device fitted in your consumer unit (fuse box). It detects dangerous faults — such as electricity passing through a person — and cuts the power in as little as 30 milliseconds, fast enough to prevent electrocution.

Does Your Home Need One?

Yes, in most cases. Under the current wiring regulations (BS 7671 18th Edition), RCD protection is required for:

All socket outlets up to 20A (in virtually all locations)

Cables buried in walls at less than 50mm depth

Outdoor circuits (garden sockets, sheds, garages)

Bathroom circuits

Most lighting circuits in dwellings

What Should You Check Safely?

Look at your consumer unit — does it have RCD switches (usually wide rocker switches) or RCBO breakers?

If you have an old fuse board with rewirable fuses and no RCDs, this is a significant concern

Do not attempt to open the consumer unit or carry out any electrical testing yourself

Legal Position for Homeowners vs Landlords

Owner-occupiers: No direct criminal penalty for an existing installation lacking RCDs, but any electrical work carried out without upgrading protec
