The search is on to bring a major business to Gloucestershire to fill the rather large shoes left by the departure of a firm tipped until recently as a future FTSE 100 company.

The 300-plus staff at Gloucester-headquartered nuclear power firm Horizon do not need telling again of the sudden demise of the business, which looked set to be an integral part of the UK's energy sector for the foreseeable.

That was until Japanese owners Hitachi pulled the plug on plans to build UK's next generation of nuclear power stations at Wylfa Newydd in north Wales and Oldbury in South Gloucestershire.

Which was immediately followed by news earlier this year of wholesale redundancies at the Brockworth business, leaving its purpose-built in 2016 52,000 sq ft headquarters with 650 workstations all but empty.

Most of those staff have now left the building in question. And that building, Sunrise House, on Gloucester Business Park, is now back on the market.

Ian Wills, director of office agency at JLL's Bristol office is handling the instruction to find a new tenant for the building.

"I advised Horizon on its leasing of the building initially so have known them for some time and it is such a shame a high value employer of this type is reducing its presence. We aim to identify another major organisation to take over Sunrise House," said Mr Wills.

"Horizon has undertaken an extremely high quality fit-out and the building benefits from a restaurant, large shower and changing facility, meeting rooms, office furniture, excellent IT and telephone infrastructure as well as high level security features. It is only three years old and could save an organisation considering investing in a new premises millions of pounds in fit-out or build costs."

Gloucester Business Park is home to several of the county's major employers including the NHS, Ageas Insurance, Laithwaites Wine and G-Tem. The park recently announced major lettings to GE and Ecclesiastical Insurance.

The site has direct access to junction 11A M5 and range of amenities including Tesco Extra, a gym, a pub, hotel and coffee shop.
