Bathrooms need carefully planned electrical installations. With water, moisture and electrical equipment all sharing the same space, every fitting, circuit and connection needs to be suitable for its location and installed correctly.
At NC Electrical, we provide professional bathroom electrics in Henley-on-Thames and the surrounding areas for homeowners, landlords, developers and commercial clients. From lighting and extractor fans to electric showers and complete bathroom renovation electrics, we deliver safe, practical solutions tailored to your property.
Whether you're upgrading an existing bathroom or starting a complete refurbishment, we'll help you plan the electrical work properly from the outset.
We've been delivering electrical installations for over 40 years as a family-run business based near Henley-on-Thames.
Customers choose us because we combine practical experience with careful workmanship and straightforward advice.
We don't take a one-size-fits-all approach. We'll consider your bathroom layout, existing wiring and planned fixtures before recommending the most suitable electrical setup.
You can learn more about our experience and credentials on our Accreditations page.

Whether you're refreshing one feature or undertaking a complete renovation, we can provide the electrical work needed to create a safer and more functional bathroom.
Our bathroom electrical services include:

Good bathroom lighting needs to balance practicality, appearance and electrical safety.
We install lighting solutions for bathrooms of all sizes, including:
The type of fitting that can be installed depends partly on its position in relation to the bath or shower. Bathrooms are divided into electrical zones, with equipment closer to water sources subject to stricter requirements.
We'll select and install fittings suitable for their intended location rather than simply choosing a light based on appearance alone.
If you're looking to improve lighting elsewhere in your property, see our LED Lighting services.
Effective ventilation is important for reducing moisture and condensation in bathrooms.
We can install or replace electrically powered extractor fans and ensure they are connected safely and positioned appropriately.
Depending on your requirements, options can include:
If you're renovating, it makes sense to consider ventilation early in the project so cabling, switching and positioning can be planned alongside lighting and other electrical work.
Electric showers place a significant demand on an electrical installation and require a correctly designed supply.
Electrical Safety First advises that an electric shower should have its own circuit and be installed by a registered competent electrician.
Before connecting or replacing an electric shower, we'll assess factors such as:
If the existing system is not suitable for the proposed shower, we'll explain what electrical improvements are needed before installation.
Bathrooms are classed as special locations because the presence of water increases electrical risk.
BS 7671 divides the areas around baths and showers into zones. These zones determine what types of electrical equipment can be installed and the level of protection required.
Zone 0 is the area inside the bath or shower tray itself.
Only equipment specifically suitable for use in this location can be installed, and strict extra-low-voltage requirements apply.
Zone 1 covers the area immediately above the bath or shower and extends vertically according to the position of the fixed shower head or the relevant prescribed height.
Equipment installed here must be suitable for the location and protected appropriately against water.
Zone 2 generally extends 600mm beyond the boundary of Zone 1.
Electrical equipment used within this area must again be suitable for the conditions and comply with the relevant requirements for bathroom installations.
Areas beyond Zones 0, 1 and 2 are subject to fewer bathroom-specific restrictions, but electrical equipment must still be suitable for the environment in which it is installed.
We'll assess the exact position of every fitting before installation.
For independent guidance on bathroom zones, see the NICEIC guide to bathrooms and electrics.

Residual Current Devices, commonly known as RCDs, provide additional electrical protection by rapidly disconnecting the supply when certain leakage currents are detected.
Current electrical safety guidance requires circuits in or passing through bathrooms and shower rooms to have appropriate RCD protection.
If you're planning bathroom work and your existing electrical system has limited or outdated protection, we'll assess the installation and advise whether improvements are required.
For older properties in particular, it may be sensible to combine bathroom improvements with a wider Electrical Testing & Inspection assessment.
Standard socket outlets are subject to strict restrictions in bathrooms because of their proximity to water.
Electrical Safety First states that standard sockets are not permitted unless they can be positioned at least 2.5 metres horizontally from the boundary of Zone 1. Purpose-designed shaver supply units have separate provisions and can be suitable in locations where an ordinary socket would not be permitted.
We can install suitable shaver points for:
We'll always assess the proposed position before recommending an outlet.

Planning bathroom electrics early can prevent compromises later in a renovation.
Before walls are tiled and finishes are completed, it's useful to decide where you want:
We'll work alongside your bathroom installer, builder or other trades where required so the electrical installation fits naturally into the wider project.
If your renovation forms part of a larger property upgrade, our Full Rewire service explains when more extensive electrical work may be appropriate.
Henley-on-Thames and the surrounding areas include many older and period homes where bathroom renovations can uncover electrical installations installed to previous standards.
Older electrics do not automatically need replacing simply because of their age. Their condition, safety and suitability for the proposed work are what matter.
During a bathroom project, we may check areas such as:
If we identify an issue, we'll explain the options clearly rather than recommending unnecessary work.
If you've recently bought an older property, our electrical services for New Home Buyers can help you understand the condition of the wider installation.
Rental bathrooms need to remain safe, reliable and suitable for regular use by tenants.
We work with landlords on bathroom-related electrical work, including:
If an EICR identifies electrical issues affecting a bathroom, we can advise on the required remedial work.
Learn more about our electrical services for Landlords or our dedicated EICR Testing service.
We'll discuss your plans, inspect the existing electrical installation where necessary and establish what electrical work is required.
For renovations, we'll also consider the proposed position of baths, showers, furniture, mirrors and other fixtures.
We'll determine suitable locations for lighting, ventilation, controls and other electrical equipment while taking bathroom zones and safety requirements into account.
Our electricians carry out the agreed work carefully and in accordance with applicable electrical requirements.
We work neatly and coordinate with other trades where necessary to keep your project moving smoothly.
Once the work is complete, we'll carry out the appropriate electrical testing to confirm that the installation is operating safely.
Some electrical work in bathrooms is notifiable under Part P of the Building Regulations in England, particularly additions or alterations within defined special locations and the installation of new circuits.
Where notification or electrical certification applies to the work we've completed, we'll ensure the relevant requirements are deal

It depends on where they are installed.
Bathroom zones determine the level of protection required for electrical equipment close to baths and showers. Lighting installed in certain zones must meet the relevant requirements for resistance to water.
We'll select fittings suitable for their exact location.
Yes. LED downlights can provide practical, efficient bathroom lighting when correctly selected and installed.
The required specification depends on where each fitting sits in relation to the bath or shower.
Yes. We install and replace bathroom extractor fans, including timer and humidity-controlled options.
We'll recommend a suitable system based on the room and your existing electrical setup.
We can carry out the electrical installation required for suitable electric showers, including dedicated circuits where necessary.
Before installation, we'll check that the electrical supply, cable and protective devices are appropriate for the proposed shower.
Standard socket outlets are heavily restricted in bathrooms.
They are not permitted within 2.5 metres horizontally of the boundary of Zone 1. Purpose-designed shaver supply units are treated differently.
We'll advise on safe and compliant options for your bathroom layout.
Bathroom circuits require appropriate RCD protection under current electrical safety requirements.
We'll assess your existing installation and make sure the work we carry out has the required protection.
Certain work is.
Under Part P in England, installing a new circuit is notifiable, as are certain additions or alterations to existing circuits within the defined special location around a bath or shower.
We'll explain whether notification applies to your particular project.
Often, yes.
A bathroom renovation does not automatically mean the entire property needs rewiring. We'll assess the existing circuits and advise whether they can safely support your proposed improvements.
Where wider issues are identified, we can discuss targeted remedial work or our Full Rewire service where appropriate.
Yes. We provide electrical services for domestic and commercial clients, including suitable bathroom and washroom electrical installations.
