Amazon is to sign the biggest letting in Welsh history at a Welsh Assembly-owned site in Swansea.

The global on-line retailer is to sign a pre-let for 807,300 sq ft (75,000 sq m) of logistics space at the 33-acre (13 ha) Jersey Marine site on the outskirts of city.

The news of the deal was announced today by Andrew Davies, minister for enterprise, innovation and network said: ‘Amazon is one of the world’s biggest brands with tens of millions of customers globally.’

He said: ‘This decision by Amazon means Wales will now be part of the multi-million pound European market segment for on-line retailing and we welcome this significant foothold in Wales by a world-class company.’

Terms of the deal have not been disclosed but it is thought that Amazon will sign a 15-year lease at a rent of between £3/ sq ft (£32.29/ sq m) and £4/ sq ft (£43.05/ sq m).

The regional distribution centre will be the fourth taken by Amazon in the UK including sites in Scotland and Luton.

The first unit will be 400,000 sq ft (37,160 sq m) and will be ready for use in October.
