Installing an Electrical Shaver Socket
The advent of bathroom gadgets such as electric toothbrushes has meant that more and more of us need to use a shaver point in the bathroom. Fitting a shaver socket is a relatively straightforward task, but as with any type of work involving electricity, it is best to fully understand the job before getting started, and if in doubt at any stage, call in a professional.
Getting Started
The first job is to work out where the cables and electricity supply runs through the house, and working out where the best place would be to have the shaver socket, and how it is to be connected into the mains. This may affect where in the bathroom you decide to have the shaver socket, but the most common position is close to the sink or by a mirror. Mark on the wall the position of the new socket using a pencil and check with a level to see that it is straight.
Inserting the Socket
Once the position for the socket has been marked, cut the correct size of hole in the wall. If cutting into plasterboard this is a simple task; if the wall is brick or stone it will require more specialist equipment. Do not cut the hole in wall too large as it will need to be filled at a later stage and it will look less professional than a snugly fitting shaver socket. Secure the shaver socket onto the wall using screws and make sure everything is firmly attached.
Attaching the Wires
Wiring the shaver socket up to the mains is the trickiest part of the process. Turn off the electricity supply at the mains before starting any work with the wiring. Route the wires from the back of the shaver socket through the walls to the mounting box. Again, this is a simple process if the walls are plasterboard and trickier if they are brick or stone. Connect the wires up to the shaver socket, fastening the earth, live and neutral wires to the corresponding terminals. Check the wiring diagrams carefully to make sure that no mistakes are made with the colour coding of the wires, as this has changed recently and in older houses the colours of wires may be different from on a modern shaver socket. Ensure everything is tightened up securely and that the shaver socket is sealed properly with waterproof sealant to stop any water getting into the electricity. Test the shaver socket with a circuit tester, and then plug in a shaver to see if it is working properly. If there are any problems, check that all the connections are tightened correctly and that no wires have worked loose while the socket was being placed.
Safety
Under new regulations, any electrical work which is done in the house, including installing a new shaver socket, has to be checked and certified by a qualified electrician. These measures are to prevent electrical fires or other accidents caused by poor wiring.
🔌 10 Frequently Asked Questions About Installing a Shaver Socket
Installing a shaver socket in your bathroom is a practical upgrade—especially if you regularly use electric razors or toothbrushes. However, because it involves electricity and is located in a high-moisture area, there are specific safety considerations and regulations to follow. Here are the most common questions homeowners ask before fitting one.
1. What is a shaver socket?
A shaver socket, also known as a shaver point, is a wall-mounted electrical outlet designed specifically for low-power appliances like electric shavers and toothbrushes. It typically includes:
-
An isolated transformer for added safety
-
Dual voltage output (usually 115V and 230V)
-
Compatibility with both UK and European plugs
It’s a safer alternative to using a regular power outlet in the bathroom.
2. Can I install a shaver socket in any bathroom?
Yes, but with restrictions.
In UK bathrooms, sockets must comply with IP zoning regulations:
-
Shaver sockets can be installed in Zone 2 or outside of any zones.
-
They must be at least 60 cm away from the bath or shower and not directly above them.
-
Always check the manufacturer’s guidance and comply with BS 7671 Wiring Regulations.
3. Do I need a qualified electrician to install one?
Yes, in most cases.
Installing or altering electrical circuits in a bathroom is considered notifiable work under Part P of the Building Regulations (England and Wales). This means:
-
You must use a registered electrician, or
-
Notify your local building control before doing it yourself (rarely advised)
This ensures the installation is safe and legally compliant.
4. Can I wire a shaver socket into a normal ring main or socket circuit?
No.
Shaver sockets must be connected to a fused spur off a lighting circuit, or more commonly, to the bathroom lighting circuit. This is because:
-
They are low current devices
-
Direct connection to a ring main could be unsafe
Always follow manufacturer instructions and use a 3A fuse in the fused spur.
5. What’s the difference between a shaver socket and a regular power socket?
The key difference is electrical isolation.
Shaver sockets contain an isolating transformer, which:
-
Reduces risk of electric shock in wet environments
-
Limits power output
-
Allows safe use of devices designed for 115V (USA-style) and 230V (UK-style) plugs
Standard sockets are not allowed in UK bathrooms, except in certain very specific zones with RCD protection.
6. Can a shaver socket power a hairdryer or other high-power appliance?
No.
Shaver sockets are only suitable for low-power items such as:
-
Electric shavers
-
Rechargeable toothbrushes
-
Facial trimmers
Plugging in a high-power appliance like a hairdryer or straighteners can overload the transformer, causing it to shut off or fail.
7. How high should a shaver socket be installed?
There is no specific height regulation, but best practice is:
-
At least 1.1–1.2 metres above floor level
-
Out of splash zones, and not directly above sinks or basins
-
Easy to access without straining
Always combine practical positioning with compliance to electrical zone guidelines.
8. Can I install a shaver socket inside a bathroom cabinet or mirror unit?
Yes, and it’s often a good option.
Many illuminated bathroom mirrors or cabinets include a built-in shaver socket:
-
This can tidy up cable clutter
-
It keeps the socket discreet and splash-resistant
-
Installation may still need to be signed off by an electrician
Make sure the mirror unit is IP-rated for bathroom use.
9. Do shaver sockets need to be RCD protected?
Yes.
All circuits in a bathroom, including those supplying a shaver socket, must be protected by a Residual Current Device (RCD) with a maximum rating of 30mA. This is a key safety requirement in modern UK installations.
10. How much does it cost to install a shaver socket?
Costs can vary, but typically:
-
£80–£150 for supply and installation by a qualified electrician
-
More if additional wiring, RCD protection, or chasing walls is needed
-
DIY installation is generally not recommended due to Part P and safety considerations
Always get a quote and check credentials if hiring a tradesperson.
🧰 Final Thoughts
Shaver sockets are a convenient and safe addition to modern bathrooms, but electrical safety must come first. Whether you’re installing a standalone unit or opting for a cabinet with an integrated socket, always follow regulations—and when in doubt, hire a professional.
