Bradford-based replacement doors and windows company Safestyle Uk is set to float on the Alternative Investment Market next month in a deal worth £70 million - the largest AIM company flotation of 2013.

The company, which makes and installs PVCu windows and doors, said it intends to place ordinary shares worth around £70 million and the shares should start trading on the AIM market on December 11 with an initial market capitalisation of approximately £77 million.

Since its launch in 1992, Safestyle has grown into the largest company in the UK homeowner window and door replacement market, manufacturing 232,000 frames in 2012 and carrying out more than 50,000 installations. It has ten installation depots and 29 sales offices throughout the country.

Safestyle has increased its market share nationally from 4.4 per cent in 2007 to 7.5 per cent in 2012. In a market that has declined 35 per cent from its 2007 highpoint, the company has managed to sell 250,.000 window frames annually.

In the six months to June 30 2013, Safestyle had revenues of £62.6 million and pre-tax profits of £7.8 million. And since then trading has been in line with directors’ expectations.

On admission to AIM the Safestyle board will comprise Steve Halbert as non-executive chairman, Steve Birmingham, chief executive, Mike Robinson , finance director and Chris Davies, non-executive director. They will hold around ten per cent of the issued ordinary share capital of the company.

Steve Birmingham said: “This marks a major milestone for Safestyle which we believe will increase the profile of our business, provide further credibility to our leading offering and enable us to put in place share incentive plans for staff whose dedication and hard work has contributed significantly to the success of our company.

“We are ideally positioned to capitalise on future growth opportunities and we are looking forward to a successful future as a public company.”
