Mark Group was founded in 1974 in Leicester, England by John and Kathleen Cottingham and has grown to become a leader in energy saving and generation solutions.

The core business structure was originally built around home insulation but with advances in technology and the rise in awareness of the need to reduce energy consumption, Mark Group’s business plan was tailored for prosperous growth.

Son Lee Cottingham joined the family business in 1996 and now as Group CEO, has not only built on the solid building blocks which were laid almost four decades ago, but has driven the business to achieve even higher levels of success.

Operating across the whole of the UK and with the expertise to advise, specify and install one of the largest ranges of energy saving and energy generating technologies anywhere in the country, the company really has made its mark.

Domestic to commercial, public and private sectors and around 1,300 employees nationwide – working for Mark Group opens the door to a world of possibilities. Yet the business continues to hold strong to the family values at its heart.
