is targeted for £9m in the next four years.

Highlights of the past 25 years include winning the Queen’s Award for Innovation and becoming one of the success stories of the 2012 London Olympics – installing and commissioning several leak detection systems in the main stadium, the white water canoe course and the Olympic village.

Last year, Andel installed its Floodline system in several prestigious London buildings, including The Shard, the Houses of Parliament, the O2, the “Walkie Talkie” building and Canary Wharf. The company also won a £75,000 contract to install water leak detection systems on each floor of Tower 1 and Tower 2 in Marina Bay Financial Centre in Singapore.

Julie Greenwood was Ian’s first employee – she started as his assistant before becoming operations director and is now managing director. She said a major focus for the firm was to expand its exports. It has distributors in countries including Italy, Poland, the Netherlands, Australia, Singapore and Hong Kong and is breaking into the US market. Andel began by developing leak detection systems to prevent flooding, but has expanded to design, manufacture and supply systems covering water, gas and oil. The firm has also developed a flood defence product, Rebund, a system of barriers resembling garden fencing to protect property in the event of floods. It also provides emission interceptors – tanks set into the ground to capture waste oil and supplies them to sites including bus depots and car dealerships. It also provides a consultancy service to steer clients through the regulatory jungle around the storage of oil on premises.

Julie said: “Since Ian died three years ago we had a year of stabilising the company. But in the past two years sales have increased dramatically.

“That has given us the ability to reinvest in the company, mainly on research and development because without R&D and bringing new products online the company will stagnate.

“We have also invested in systems and procedures to provide a good basis for the company to grow.”

Julie said: “Ian was an ideas man who loved to think of the next step forward. He was very good at starting projects and getting the right people to take them on.

“We have a good team with a “can do, will do’ mentality. Without having a good team of people prepared to work hard the company can’t go anywhere. It’s also about having good relationships with the financial institutions and suppliers. We try very hard to use suppliers within Yorkshire and support the local economy.”

And she added: “It is important we carry on Ian’s legacy. Now is the time to grow the business.”
