Bathroom Lighting Installation

Good bathroom lighting needs to balance practicality, appearance and electrical safety.


We install lighting solutions for bathrooms of all sizes, including:


  • LED ceiling downlights
  • Mirror lighting
  • Vanity lighting
  • Feature and ambient lighting
  • Shower-area lighting where suitable
  • Energy-efficient lighting upgrades


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.

Extractor Fans & Bathroom Ventilation Electrics

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:


  • Standard extractor fans
  • Timer-controlled fans
  • Humidity-sensing fans
  • Fans linked to bathroom lighting
  • Continuous-running ventilation systems where appropriate


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 Shower Installations

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:


  • Existing circuit capacity
  • Cable suitability
  • Protective devices
  • RCD protection
  • Isolation arrangements
  • The condition of the existing electrical installation


If the existing system is not suitable for the proposed shower, we'll explain what electrical improvements are needed before installation.

Bathroom Electrical Zones Explained

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


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


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


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.


Outside the Zones


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.

RCD Protection for Bathroom 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.

Shaver Sockets & Bathroom Power

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:


  • Electric shavers
  • Electric toothbrush charging
  • Bathroom grooming equipment where appropriate


We'll always assess the proposed position before recommending an outlet.


For more independent bathroom safety information, visit Electrical Safety First.

Bathroom Electrics for Renovations & Refurbishments

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:


  • Ceiling and mirror lighting
  • Extractor fans
  • Electric showers
  • Shaver sockets
  • Illuminated mirrors or cabinets
  • Underfloor heating controls
  • Switches and isolators
  • Additional circuits


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.

Bathroom Electrics for Older Properties

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:


  • Existing wiring condition
  • RCD protection
  • Circuit capacity
  • Earthing and bonding arrangements
  • Existing fittings
  • Previous alterations
  • Suitability for additional electrical loads


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.

Bathroom Electrics for Landlords

Rental bathrooms need to remain safe, reliable and suitable for regular use by tenants.


We work with landlords on bathroom-related electrical work, including:

  • Lighting repairs and upgrades
  • Extractor fans
  • Electrical fault finding
  • Remedial work following inspections
  • Shower circuits
  • Replacement fittings
  • Electrical testing

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.

Bathroom Electrics FAQs

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.
