    Trade Customer Success Story
    “Working with Rainbow Safety has transformed our safety sign sales.”

    With the support and marketing tools provided, our sales have grown to over £3,000 per month.

    Fire extinguisher servicing margins are not what they used to be, so supplying safety signs has become a valuable additional revenue stream for our business. On one warehouse safety survey alone we £5,100 in a single order.

    Previously we were regularly asked to supply safety signs but couldn’t compete with internet prices while maintaining healthy margins. Working with rainbowsafety.co.uk.
