Buying electrical & lighting supplies from Plumb Supply
Cable, consumer units and protection
Twin and earth still covers most domestic circuits — 1.0mm² and 1.5mm² for lighting, 2.5mm² for ring finals, 6mm² and above for showers and cookers depending on load and route. SWA is the choice for external and buried runs to garages and outbuildings. Consumer units must be metal-clad in domestic properties, and current wiring regulations expect RCD protection on the circuits that need it plus surge protection where the installation warrants it. RCBO boards cost more but isolate a fault to a single circuit, which customers notice the first time something trips.
Lighting and wiring accessories
Fire-rated LED downlights are standard in ceilings below habitable rooms, and IP-rated fittings are required in bathroom zones. Match colour temperature across a room — mixing 3000K and 4000K in the same ceiling is the most common complaint after a lighting refit. Sockets, switches, dimmers and USB outlets are where a finish is judged, so keep the plate range consistent through the property. Check dimmable drivers against the fitting before ordering; not every LED lamp dims cleanly on a trailing-edge dimmer.
Ventilation and electric heating
Extract fans in bathrooms and kitchens must meet the ventilation rates in the building regulations, and an inline fan with rigid ducting is quieter and more effective than a long flexible run. Heat recovery units suit airtight properties and refurbishments where condensation is a recurring problem. Panel heaters, electric towel rails and storage heaters are the practical answer in conversions and extensions where extending the wet heating circuit is not viable.
Electrical & Lighting Supplies — frequently asked questions
What electrical products can I order?
Cable and conduit, consumer units, circuit protection, switches, sockets and wiring accessories, LED lighting, extract ventilation, electric heating and test equipment.
Do you supply electrical products to trade customers?
Yes — trade accounts see their pricing on every product page and can request quotations for larger material schedules.
Which downlights can I fit in a bathroom?
Use fittings with an IP rating suitable for the bathroom zone they sit in, and fire-rated versions where the ceiling separates habitable spaces.
Can I replace a socket faceplate myself?
No. Even a like-for-like faceplate swap involves working on live wiring, and fixed electrical installation work should always be carried out by a qualified electrician. Much of this work is also notifiable under Building Regulations Part P in England and Wales.

Most do, and older properties do not always have a neutral present at every switch position. An electrician can check your wiring and recommend a suitable product or wiring change.
Read the full guide: A Homeowner's Guide to Switches and SocketsWhy does my LED bulb flicker on a dimmer switch?
This usually means the dimmer is not designed for LED loads, or the total wattage on the circuit is below the dimmer's minimum load. Choosing an LED-compatible dimmer matched to the bulb wattage generally resolves it.
Read the full guide: A Homeowner's Guide to Switches and SocketsWhat IP rating do I need for an outdoor socket?
It depends on the exact location and level of weather exposure. A qualified electrician should assess the position and specify the correct rating and circuit protection.
