We hold substantial stock across our most popular products and ranges. Due to the variety of finishes and configurations available, some items may need to be sourced from our suppliers. We receive regular deliveries from all major suppliers, helping us keep delays to a minimum.

Typical dispatch: 3–5 working days. Once dispatched, most UK mainland deliveries arrive within 1–2 working days.

To get your goods to you sooner, we may send all or part of your order directly from one of our trusted suppliers. This means items may arrive separately, through different couriers and with separate tracking information. RS Electrical Supplies remains your point of contact throughout.
