Utilitywise is creating 200 jobs to meet the huge demand from businesses to reduce their energy usage and costs.
The energy consultancy currently employs 1,500 staff and has 27,000 clients across the UK.
The extra staff will be recruited over the next few months and be primarily based at the company’s new North Tyneside premises.
Geoff Thompson, chief executive of Utilitywise, said the new hires “reflect the growing demand for our services with small, medium and large businesses”.
The majority of the new workforce will be energy consultants advising businesses on the Utiltywise Utility Management Plan which allows business owners to turn off the lights remotely and reduce energy use at peak times.
The new jobs come shortly after Utilitywise appointed Brin Sheridan to the board as chief operating officer.
Thompson said: “I am excited to be announcing the appointment of Brin. He brings a wealth of experience from his previous roles and will be integral in ensuring that, as our range of products and services expands, we are well-placed to continue on our growth trajectory.”
