Mark’s passion in renewable solutions and the whole area of energy transformation has continued, entailing long term investment in trials and testing a number of technologies targeted at helping customers meet their carbon reduction targets and assisting in lessening the burden of fuel poverty. This passion and investment has positioned Smith Bros as a leading provider of renewable solutions through Helix50, a joint venture company bringing together a number of like-minded individuals and committed companies.
