The double-glazing company which had to give undertakings to the Court of Session over its products has gone into liquidation.

The double-glazing company which had to give undertakings to the Court of Session over its products has gone into liquidation.

MB Designs (Scotland), based in Kirkintilloch, East Dunbartonshire and trading as the Quick Group, was pursued last year by the Office of Fair Trading after hundreds of complaints about the quality of its doors, windows and conservatories.

The OFT obtained interim enforcement orders from the Court of Session to give consumers protection, in the first case of its kind in Scotland. It then went on to seek a final enforcement order, but at the beginning of this year MB Designs and its directors, Martin Black and Paul Betts, gave undertakings to the court about the future conduct of the company.

Filings at Companies House yesterday reveal that the business had assets of £302,000, and that the directors had previously been involved in three insolvent companies and two dissolved companies.

Black, 48, principal shareholder, and sales manager Shaun Lagan only became directors of the company in recent weeks, replacing Betts, Anne Black, 48, and Fraser Black, 22.

Mike Haley, head of consumer protection at the OFT, said earlier this year: "These undertakings are good news for consumers who should be able to rely on any business to supply and fit the double- glazing products that they have ordered to a satisfactory standard."

He said the OFT would closely monitor the undertakings and take action if they were breached.

The original court action, brought under the Enterprise Act, came after hundreds of complaints to South Lanarkshire Council's trading standards service from customers unhappy with the supplies and workmanship.

MB Designs argued that an independent contractor carried out the installation work in many cases and denied any responsibility for defects. Martin Black said earlier this year: "We don't believe there was ever a problem in the past."

South Lanarkshire Council said yesteday that the company had traded variously as The Quick Group, Quick Fit, Quick Trade, Quick Glass and Quick Decks and Spas.

Peter Sherry, the council's trading standards manager, said the company was likely to be insolvent. "Consumers with outstanding complaints are likely to be treated as unsecured creditors and accorded the lowest financial priority."

He said any outstanding or remedial work was unlikely to be completed, although any new customers who had paid deposits by credit card or finance agreement would be able to secure a refund.

He added: "South Lanarkshire Trading Standards has a number of outstanding consumer complaints against the company that it will continue to deal with."

The liquidator is Ken Pattullo at Begbies Traynor in Glasgow.
