Administrator Zolfo Cooper has shut down the group and all of its sites and is now only holding out hope for a buyer for the Wyvis Roofers subsidiary which employs 30 people.
Zolfo Cooper was appointed at the £31m group earlier this week to run its operations in Inverness, Glasgow, Dundee, Bathgate, Stornoway and South Uist.
Elizabeth Mackay, lead partner for Zolfo Cooper in Scotland, said: “It was with great regret that we have had to take today’s extremely difficult decision.
“We are fully aware of the impact that these redundancies have on the communities in which UBC Group operated for many years.
“My team and I will be working with all relevant agencies and third parties to seek to minimise the impact as much as possible.
“Unfortunately the group’s overall financial position had become untenable and a lack of outside interest in acquiring the business as a going concern meant that today’s decision was the only remaining course of action available.
“We remain hopeful that we are close to effecting a sale of Wyvis Roofing and expect to conclude this early next week.
“This will allow for the preservation of some 30 jobs in the Inverness area and allow the business to continue to serve its existing contracts.”
