The extension of the deal follows the success of the first phase awarded to Premier by the Department of Health and Social Care for an initial 25 sites from Inverness to Portsmouth.

Since the first project was delivered in Bolton, Premier has now set up standalone community testing sites in towns and cities across the country including Inverness, Leamington Spa, Dudley, Nottingham, Aylesbury, Buxton and Liverpool.

The next batch of sites will be in Leeds, Redcar, Durham and Oadby in Leicestershire.

David Harris, Managing Director of Premier Modular, said: “The work our teams have carried out across the country and round the clock has been phenomenal and has been very well received in those communities.

“Our colleagues continue to pull out all the stops in the factory and on site to set up the testing sites in just two to three days which really is an outstanding achievement given the bespoke nature of the buildings and the complexity of the site requirements.

“We are delighted this work has been recognised with the doubling of our contract to 50 sites.

“This contract also demonstrates just how responsive modular construction can be when combined with strong project management and logistical operations to help the NHS respond to urgent local needs.”

Premier has invested £7m in its hire fleet to allow a rapid response for major contracts.

It manufactures the test buildings to order and has put in place an entire extra shift working through the night at its modular building factory in East Yorkshire>

Each standalone test site has a 110sqm purpose-designed testing building pre-fitted with eight patient cubicles, hygienic walls, separate staff entrance and exit, test collection and drop off zones and a family testing room.

Premier’s contract also includes the supply of welfare facilities in three buildings to accommodate a PPE room, stores, test preparation, staff rest room, kitchenette and toilets.
