The offices of Scottish & Southern Energy in Havant have been getting involved with Blue Day.
The majority of staff were dressed in blue and a cake sale and raffle was held.
Facilities Assistant Alison Savage, 43 said: ‘It’s great to see so many people in blue shirts. We’ve done this for the last four or five years now so it always does well.
‘Some of the staff have been out collecting money for the last couple of hours and they haven’t come back yet.
‘So we hope that means they’ve done well!’
