LED Dimmer Switches UK: Why Most of Them Flicker and How to Fix It
Your LED bulbs flicker. Or they buzz. Or the dimmer itself hums through two walls at 11pm. None of this is a faulty bulb — nine times in ten, it's a dimmer switch that was never designed for LED loads.
This guide explains the difference between leading edge and trailing edge dimmers, why minimum load ratings matter, how to check compatibility before you order, and which dimmers actually work: Varilight V-Pro, BG Evolve and Hamilton Hartland G2 compared side by side. Also covers 2-wire vs 3-wire wiring for retrofits in older properties, 2-way dimming circuits, and bathroom compliance under BS 7671:2018 Regulation 701.
