How Close Can a Socket Be to a Sink in the UK?

General Mubashir Ahmed 3 April 2025 0 Comments

When installing electrical sockets near a sink, safety is the top priority—especially in kitchens or utility areas where water and electricity are both present. In the UK, the positioning of sockets is governed by BS 7671 (IET Wiring Regulations).

Here’s what you need to know:

✅ Minimum Distance Between a Socket and a Sink

The recommended minimum distance between a socket outlet and the edge of a sink is:
👉 300mm (30cm)

This applies horizontally, not just directly behind the sink. It’s measured from the edge of the sink/drainer, not the centre or tap.

⚠️ This distance helps avoid the risk of water splashes reaching the socket and reduces the danger of electrical shock.

💧 What If You Can’t Meet the 300mm Rule?

In tight spaces:

You may still be allowed to install a socket closer if there’s no realistic risk of water splashing
The socket should be:
- Positioned above worktop height
- Protected by a 30mA RCD (residual current device)
- Ideally installed sideways or under cabinets to reduce exposure

Always follow BS 7671 guidance and consult a qualified electrician.

🚿 What About Bathrooms?

Sockets in bathrooms have stricter rules:

Standard sockets are not allowed within 3 metres of a bath or shower
Only shaver sockets (with isolation transformers) are allowed within certain zones

🛠️ Other Kitchen Socket Rules to Know

Sockets should be placed at least 150mm above the worktop
Avoid placing sockets:
- Directly above hobs or ovens
- Under sinks where leaks could pose a hazard

Conclusion

In UK kitchens, a socket must be at least 300mm away from the edge of a sink to comply with safety recommendations. This helps prevent water and electricity from coming into contact. When in doubt, always consult a qualified electrician to ensure your setup meets regulations and keeps you safe.
