brilliant service helped with product codes and ordering. switches arrived a day later

Exceptional quality, both on hardware and the switch. Only gripe is the bottom switch grub screws can't be accessed from the top, like many cheaper alternatives. This is actually a very useful feature. Oh well.

I have used Corston’s light switches, sockets and door knobs throughout our projects and will continue. Their customer service is second to none and they’re telephone advice and ordering service is exemplary.
