Nicko launched his carbon neutral cab company, made up of a fleet of Toyota Prius cars, in 2007 just after graduating from university. Three years on and he’s celebrating striding well past the £1m turnover mark with a ‘decent profit margin’.

Around 90% of the company’s revenue comes from account work and clients range from eco-friendly celebrities to corporate giants such as Unilever. Initial funds to start the business came from savings and a family and friends investment round, but Nicko has since followed this on with a further £300,000 of angel funding.

The young entrepreneur has big ambitions for the company and is projecting an extra £1m of revenue for the coming year. In his words, Climatecars in on course for ‘more scale, more profit and better margins’.
