The Norville Group has entered administration - just days after the company's optician practices were sold.

More than 130 jobs are being lost at the family spectacle firm's laboratories in Gloucester, Bolton, Seaham in Durham and Livingston in Scotland.

Simon Girling and Christopher Marsden of BPO LLP have been appointed joint administrators and are hoping to sell parts of the business.

Hakim Group, who bought the Norville Opticians retail business last week, said the nine practices around Gloucestershire are not affected by the administration and will continue to operate under the Norville name.

The largest group of independent opticians in the UK says investment involves a transformation programme, which includes shared ownership opportunities for existing employees, along with significant enhancements to the product offering as well as the customer experience.

Norville Opticians director Adrian Street said: "The future is bright for Norville Opticians and our teams are as committed as ever to deliver the highest quality eye care and eyewear.

"Our best wishes go to the Norville Group and hope the good people there see a positive outcome and they come out of this situation stronger than when they entered it."

The sale of Norville Opticians will secure around 50 jobs at the practices in Gloucester, Charlton Kings, Bishop's Cleeve, Dursley, Stonehouse and Wotton-under-Edge.

Hakim Group head of business development Luke Wren said: "Job security for colleagues will always be our priority, no matter the circumstances, but I can reassure team members' jobs within the retail division will not be affected by the Norville Group's administration.

"We're incredibly excited for the opportunities that lie ahead in unleashing the full potential of Norville Opticians for our colleagues who work there."
