Founders Andy Heller and Graeme Johnston launched the company in 2016 after they found a gap in the market for a customer focused telecommunications company.

Central Telecoms started in the Central Coast and has expanded to several regional locations across NSW and Victoria, with its headquarters located right here.

"We believe that the person who sells the product has to be responsible and accountable for it," co-founder Mr Heller said.

The person that [a customer] calls overseas doesn't know them, they are an account number to them, they have a few set questions and if its not in their realm then they just put you back in the queue for somebody else to have a go.

The company specialises in NBN transitions and has experienced a 101 per cent growth for the 2018 to 2019 financial year, making its debut on the CRN Fast50 at number seven.

The CRN Fast50 recognises the country's fastest growing ICT solution providers and channel players based on year-on-year revenue growth.

"The roll out of the NBN was to level up the playing field and create a platform which gave the control back to the end user," Mr Heller said.

"It does have its challenges but when you go up against Optus and Telstra, two multi-national companies, that local touch approach is difficult to deliver at such a large scale.

"It's difficult to provide that level of consistency at that size ... people are desperate for that help and assistance."

Mr Heller said larger contracts, including NBN migrations for a financial services organisation and a transport and logistics company, had been particularly beneficial to its financial position.

Central Telecoms earned more than $2.1 million in revenue over the last financial year.

The company of about 20 employees is looking to hire some more staff to ensure their customer service stays at a high standard as they continue to expand.
