New data from aerospace trade organisation ADS shows that, despite UK companies increasing delivery rates by 6% a year for the past three years, growing demand for aircraft as passenger numbers increase means that backlog of work has risen by 9% over the past year.
This means that the work in hand for companies supplying the aerospace sector is now enough to keep them busy for nine years.
Paul Everitt, chief executive of ADS Group, said: "We've seen a very strong start to 2015 and a clear indication that UK industry is responding to the challenge of delivering a very full order book. It's clear that the UK's commitment to Industrial Strategy is working; whether that's by unlocking the supply chain, encouraging new talent or investing in research and technology.
"We cannot afford to become complacent. The UK continues to face fierce international competition and continued industrial success comes from long-term planning and sustained investment, and there can be no better argument for this than the very clear value we see the aerospace sector delivering for the UK economy."
