The value of UK exports passing through Heathrow airport is now £48 billion after strong Chinese demand for British products continued to grow.

The value of exports travelling to China from Heathrow more than doubled to £7.6bn between August 2014 and July 2015, representing 15% of the good exported from Heathrow.

Research by UK Customs suggests that if Heathrow had unconstrained capacity, China would overtake the US as the UK's most valuable export destination within two years. Asian nations already make up four of the top five UK export destinations by value.

The figures showed that human medicines are among the products leading the growth of exports to China. Although vaccines for human medicine are the UK’s sixth most valuable export via Heathrow they have risen rising by 97% and 87% respectively over the previous two years –brought about by recent world health crises.

Precious metals still remain the single most valuable export from Heathrow at around £26bn. Second placed aircraft turbojets some way behind at just £3.5bn, following closely by jewellery at £3bn.

To celebrate Export Week (9-13 November), Heathrow has partnered with UK Trade and Investment to create a unique Export Café. The installation is on site at Heathrow Terminal 5 departures until Tuesday 17th November and showcases 25 of the UK’s best exports.

Emma Gilthorpe, Heathrow's strategy director, said: "At Heathrow, we are delighted to support the UK government's 'Exporting is GREAT' campaign to help raise awareness of the benefits of exporting and support network that is in place to help businesses across Britain t reach dining tables and markets across the world.

"The true heroes of this campaign are the businesses who have gone beyond UK borders and opened new markets to the benefit of their local communities and the UK's economy."

Lord Maude of Horsham, Minister for Trade and Investment, said: "Export is GREAT' is the government's most ambitious export campaign ever, aiming to inspire and support 100,000 additional UK exporters to sell their good and services overseas by 2020. I'm delighted that Heathrow will be partnering with us to extend and sustain the campaign's reach and provide support to businesses to boost their capability and help them successfully access international markets."
