“Working with Rainbow Safety has transformed our safety sign sales.”
Before partnering with Rainbow Safety, our safety sign sales were less than £300 per month.
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 invoiced £5,100 on a single order.

We can now compete with internet prices and still make a healthy margin.

We were regularly asked to supply safety signs, but struggled to compete with internet prices while maintaining a worthwhile margin.
