The retailer has approached a number of agencies about the review as it looks to ramp up its loyalty programme across its trade customers.
TradePoint is a new Trade Counter operation at B&Q dedicated to the needs of professionals and claims to offer brands at special trade prices.
The retailer does not retain a direct marketing agency. In the past, it has worked with agencies including RMG Connect, Rapier and the now-defunct Personal.
The review follows recent advertising activity by B&Q to capitalise on the increasing number of people turning to DIY projects over bank holiday weekends.
In March, the retailer launched its "I did that" advertising campaign by McCann Erickson.
