The scale of the economic contribution of Associated British Ports' (ABP) three ports in East Anglia has been revealed in a new report by independent consultants Arup.

Together, the three ports - King's Lynn, Lowestoft and Ipswich - contribute £340million to the UK economy annually and support 5,000 UK jobs, it said.

The new statistics show that, of those totals, ABP's East Anglia Ports contribute £241m directly into the regional economy and support 3,577 jobs in the area.

The three East Anglia ports handled 2.2m tonnes of cargo in 2013.

It's a diverse business, with Ipswich exporting almost 500,000 tonnes of grain for local farmers as well as importing 140,000 tonnes of cement and more than 300,000 tonnes of aggregates annually to support the local construction sector.

Lowestoft is a renewable energy hub and key to the development of the offshore wind industry, while King's Lynn is vital to the agricultural sector, handling 350,000 tonnes of agricultural products every year, the report reveals.

The three ports combined handled more than 1.3m tonnes of agribulks and 150,000 tonnes of timber in 2013 and play a key role in connecting the region to ports across the North Sea and beyond. ABP also has a pair of five-gold-anchored marinas at Ipswich and Lowestoft providing 500 marina berths and extensive facilities supporting marine based leisure & tourism.

ABP says it is committed to developing its three ports in East Anglia, with a programme of investment expected to increase their contribution to the regional economy by £24m annually.

Andrew Harston, ABP Director based in Ipswich with responsibility for ABP's 11 short sea ports, said: 'Our ports in East Anglia are a cornerstone of the regional economy, vital for the construction industry, key to farmers accessing global markets and essential for the further development of the offshore wind industry.

'I'm proud to report both these impressive figures and our determination to build on this success with a programme of investment that will deliver growth for the regional economy.'
