An ‘ambitious‘ bid by six local authorities in North Wales to the UK and Welsh governments for £400m, could finally kick-start investment at the Bryn Cegin industrial park in Bangor.

Wales Office minister Guto Bebb spoke as the councils handed over their bid for a North Wales growth deal, calling for support for 12 projects designed to boost the region’s economy, which included the Bryn Cegin industrial estate.

Under the proposals £20 million would be spent on industrial estates in North Wales, including Warren Hall, Flintshire, Bodelwyddan and Bryn Cegin, which would hopefully kick-start private sector investment.

The bid also supports the North Wales Metro concept, promoting integrated transport around 4 hubs, as well as the redevelopment of Holyhead Port.

Mr Bebb said: “I’m not saying that £400 million will be forthcoming, but is an ambitious set of proposals that are being taken “very seriously by UK government and also by Welsh Government”.

In 2005, the 90-acre Parc Bryn Cegin received £3.5m of European funding and investment from the former Welsh Development Agency (WDA) of £4.9m.

At the time, officials said the park would attract up to 1,600 jobs, £18m of additional investment and provide more than 70,000 sq metres of floor space for businesses. The Welsh Government claimed the park would create a more “prosperous local economy”, but it has been empty ever since.

In December 2015, Liberty Properties announced proposals to develop a cinema complex, restaurant and tourism hub on the site, with the creation of up to 400 jobs, but have since blamed Brexit for “very frustrating” delays.

In August this year, Gwynedd Council approved plans for a high tech £14m dairy plant at the site which could create up to 30 new jobs.
