As well as joining the comms industry's professional body, Bright One will also work closely with the PRCA as part of its not-for-profit working group to raise awareness of opportunities and need for volunteers to offer their time to third sector organisations.
Bright One has donated 2,700 hours of pro-bono work to the charity sector, which is estimated at a value of around £300,000.
PRCA director general, Francis Ingham said: 'Bright One is an initiative we’re keen to support, as not only does it help charities with their communications needs, but also helps develop the next generation of PR professionals - the future of our industry.
'They couldn’t get off to a better start than by volunteering with Bright One.'
The agency was established by 2010 PRWeek Award young professional of the year nominee Ben Matthews two years ago.
