Stephen Metcalfe, Member of Parliament for South Basildon & East Thurrock, opened local business dBD Communications' third site in Basildon.
dBD works with large organisations such as Network Rail by developing safety communications systems, and has experienced continued growth since it was created in 2002, now employing over 40 people locally.
Mr Metcalfe said: "It was great to be invited to share in the continued success of dBD Communications and to help open their new facility.
"Businesses like dBD are the backbone of our local and national economy, and are driving us forward by creating jobs and apprenticeships."
He added: "It is crucial for government to provide a stable environment for business growth and investment, and I was pleased to see tax reduction measures in the recent Budget that will make a difference to local companies like dBD."
