First-round bids for the five-strong business, which is led by Jillian MacLean, are believed to have been submitted earlier last week. It is understood that an asking price of circa £25m has been put forward, although it is thought the group might realise a price closer to the high teens/£20m mark.
It is thought that Novus has run a rule over the business, which is backed by investment company Imbiba Partnership, while a MacLean-led, private equity-backed management buyout of the group is a possible option.
It recently secured two sites for next year and is set to announce plans to ramp up its expansion strategy.
