Working in Barnet
In Barnet we cover EN4, EN5, HA8 and 7 more postcode districts; we also cover Potters Bar, 3.1 miles away, and Borehamwood.
In Barnet, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If you are refitting a windowless bathroom in Barnet, the lighting is planned with the extractor fan so the two work together. Landlords in Barnet get an electrical certificate for new bathroom lighting, which belongs with the property's safety records.
Supplies across most of Greater London are 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
- A lighting plan: number and position of downlights, mirror lighting, switches and any shaver socket
- Testing and an electrical certificate for the work on completion
- Cable runs to each fitting, from the loft above or through the ceiling
- IP-rated fittings chosen for each zone, with IP65 downlights over the bath or shower
Decisions to make first
Integrated or replaceable LED
Integrated LED downlights are slimmer and fully sealed. Fittings with replaceable lamps let you change brightness or colour later.
Feature lighting
LED strips in niches, under a wall-hung vanity or along a plinth give enough light for night-time without full glare.
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.
