Working in Marlow
In Marlow we cover SL7; we also cover Maidenhead, 4 miles away, and High Wycombe.
Marlow gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Marlow bathroom has one central light, adding downlights and a mirror light is usually the change you notice most. For Marlow homes with a loft above the bathroom, the insulation and fire protection are checked before any downlights are cut in.
Water across much of Buckinghamshire is 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 ceiling pull-cord or a switch outside the room, with separate switching for mirror and feature lights
- 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
- Fire-rated downlights or fire hoods where the ceiling has to keep its fire resistance
Decisions to make first
Downlight positions
Evenly spaced downlights give flat, general light. Placing one over the shower and one over the basin puts the light where you actually use it.
Colour temperature
Warm white, around 3000 K, feels softer; cool white, around 4000 K, is crisper for shaving and make-up. Mixing the two in one room looks uneven.
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.
