Quick answer
Yes — for almost all bathroom electrical work you need a qualified electrician. Bathrooms are classed as “special locations” under the wiring regulations, and most new or altered circuits are notifiable under Part P of the Building Regulations. A registered electrician carries out the work, tests it and issues a certificate you can keep.
Why bathroom electrics are treated differently
Water and electricity are a genuinely dangerous combination, which is why the wiring regulations single bathrooms out for special treatment. Wet skin dramatically lowers the body’s resistance, so a fault that would give you a nasty tingle in a dry kitchen can be fatal in a bathroom. To manage that risk, the regulations divide a bathroom into protective zones, restrict what equipment can go where, and require additional protection such as RCDs (residual current devices) that cut the power in a fraction of a second if something goes wrong.
This is not box-ticking. It is the reason a bathroom fitted by a competent professional is safe to use every day for decades, and why DIY electrics in a wet room are one of the riskiest jobs an amateur can attempt.
What Part P actually requires
Part P of the Building Regulations covers the safety of electrical installations in homes. In England, work in a bathroom is treated as a special location, and a good deal of it is notifiable — meaning building control must be told, unless it is self-certified by a registered competent person.
Work that needs a qualified electrician
- New circuits — for an electric shower, towel rail or underfloor heating
- Consumer-unit (fuse board) changes or upgrades
- Moving or adding sockets, spurs and fused connections
- Wiring extractor fans, shaver points and bathroom lighting
What you get for it
- An Electrical Installation Certificate or Minor Works Certificate
- Notification to building control handled for you
- Proof of compliance for when you sell
- Peace of mind that the protection is correct
Rules differ slightly across the UK and change over time. Always confirm current requirements with a registered electrician or Plymouth City Council building control.
What “registered” means
A registered electrician belongs to a government-approved competent-person scheme such as NICEIC or NAPIT. That registration lets them self-certify their own work as compliant and notify building control on your behalf — without you paying separately for a council inspection. It also means the work has been done to the current edition of the wiring regulations and properly tested before the power is signed back on.
On every Proud Bathroom Fitters job, the electrics are carried out by a qualified, registered electrician as part of our managed team — not subbed out to whoever is free. You meet the people doing the work, and you get the certificate at the end.
Lighting, extraction and heating are all wired to the current regulations and tested before sign-off.
Can I do any of it myself?
Honestly, our advice is don’t. There are a tiny number of non-notifiable jobs — like replacing a like-for-like light fitting outside the protective zones — that a confident homeowner could technically do, but in a bathroom the safe space to do anything yourself is vanishingly small. The risk of getting a zone wrong, omitting RCD protection or leaving an untested circuit is simply not worth it when a professional can do it properly and certify it.

How it works on a Proud Bathroom Fitters job
First fix
While the walls are open, our electrician runs the cabling for showers, heating, fans and lighting — neatly chased and protected.
Second fix
Fittings go in, everything is connected, and the installation is fully tested against the regulations.
Certificate
You receive the appropriate electrical certificate and the work is notified — clean paperwork for your records and any future sale.
It is one of the reasons our clients across Plymouth and the South West trust us with whole bathrooms rather than juggling separate trades. For budgets, see our Plymouth cost guide, or read the related answer on Gas Safe and Part P registration.
Is it illegal to wire a bathroom yourself?
Notifiable electrical work must comply with Part P and be certified. Doing it yourself without the right competence and certification can breach the Building Regulations and may invalidate insurance, so it is strongly discouraged.
Will the electrician test the existing wiring too?
A good fitter will flag any obvious issues with the existing installation and recommend testing where the bathroom ties into older circuits — important in many Plymouth homes wired decades ago.
