Working in Isleworth
We work right across Isleworth — TW3, TW5 and TW7 — and in neighbouring Hounslow and Heston.
London homes in Isleworth often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Bathroom lighting in Isleworth is wired to BS 7671 with RCD protection, tested, and certified when it is finished. If you are refitting a windowless bathroom in Isleworth, the lighting is planned with the extractor fan so the two work together.
Water across much of Greater London is very hard. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- RCD protection on the lighting circuit, checked at the consumer unit and added where it is missing
- Testing and an electrical certificate for the work on completion
- A lighting plan: number and position of downlights, mirror lighting, switches and any shaver socket
- Cable runs to each fitting, from the loft above or through the ceiling
Decisions to make first
Feature lighting
LED strips in niches, under a wall-hung vanity or along a plinth give enough light for night-time without full glare.
Integrated or replaceable LED
Integrated LED downlights are slimmer and fully sealed. Fittings with replaceable lamps let you change brightness or colour later.
Rules that apply in England
In England, Part P makes a new circuit, a consumer unit replacement and any addition or alteration to circuits in a room with a bath or shower notifiable. The work must be done by an electrician registered with a competent person scheme or notified to building control. Replacing a light fitting like for like is not usually notifiable, but it still has to meet BS 7671.
