We are Open for Business

Rainbow Power Company would like to assure our customers that we are trading (not quite as normal). System designers are working from home and can customise a quote for you (free of charge) over the phone and online. We are still dispatching and posting items, with safety precautions in place. You can still order online or over the phone, and pick up items from RPC (our show room is closed however, and appointments must be made to pick up orders). We are still doing site inspections, keeping the recommended social distancing.
