DC Allen and Partners was founded in 1962 by Derek Allen as a mechanical design service. The business diversified into precision machining and in 1966 became DC Allen and Partners (Engineering) Ltd. In the 1960's and '70's the company produced components for the UK aerospace and energy industries.

Tim Allen (Derek's son) joined the company in the 1980's. Coming from an electronic engineering background, he initiated a gradual refocusing of the business onto electronics and software design and development. By 2006, the company, now DC Allen Ltd, had fully switched to electronics and software development.

Now in our 56th year, the company is run by Tim and his wife Yee, who is also an electronic engineer.
