A GROWING energy firm which has doubled its workforce over the last two years says it expects to double its sales over the next 24 months after moving into newly expanded offices.

Ipswich-based Haven Power, which sells energy to businesses, has gone from strength to strength since it was launched five years ago, and has now doubled the size of its offices.

It is celebrating the completion of a �2.5million energy-efficient extension to its office space at Ransomes Europark and is gearing up for a major sales boost as new staff get to grips with their roles.

Chief executive Peter Bennell said the company, now owned by energy firm Drax, which operates one of the UK’s largest coal-powered electricity power stations and biomass generators, both based in Yorkshire, was enjoying major growth in spite of the economic slowdown.

He expected sales this year to reach �250million, compared to about �80m two years ago, and Haven now employs 330 staff against 160 then.

“It’s a big jump,” he said. “We have gone into some different parts of the market. We have carried on the business we have been doing. We have also gone into the big industrial market now – places like airports, for example, and big factories, rather than small businesses which is where we started out.”

The impressive growth was in line with what the business had planned for, he said.

“You have got to be quite careful when you are growing that quickly that everything stays together really because what you don’t want is customers you can’t service because you have not got the people or you have not got the power to service them.”

The firm, which celebrated an accolade recently when it came top for customer satisfaction in independent research by Datamonitor, is also investing in its IT and technology.
