What our people say 

George, who progressed from Assistant Business Development Officer to Business Development Officer last year: 

“What was your route into the team? I came into Business Development after starting out in frontline roles in local authorities and then a housing charity, where I realised I wanted to continue having an impact on people’s lives, but on a bigger scale. The Assistant Business Development Officer role was a perfect progression, and after about a year I successfully applied for a Business Development Officer role. This felt really manageable given the space for development as an Assistant Business Development Officer. 

What are your favourite parts of the job? Winning contracts is a really great feeling, especially when I know they’ve been shaped with service users and colleague to make sure we’re designing services that offer the best support to the most people. I also value the constant opportunities to learn, feeling supported in my development, and seeing the decisions I’m involved in having a real impact on people’s lives.

What were your highlights from last year? Our team away day in Liverpool, which was great fun as well as chance to hear from the managers of our new Liverpool service. It was one of the first bids I worked on as an Assistant Business Development Officer, and it was amazing to see our bid come to life, being delivered by a passionate group of people.

What would you say to someone thinking of applying? I’d definitely say go for it, and once you start, embrace how much there is to learn! Make the most of a really knowledgeable and supportive team, of managers who genuinely want you to succeed, and of all the opportunities to try new things and develop new skills.” 

Holly, who has progressed from Assistant Business Development Officer to Senior Business Development Officer: 

“What was your route into the team? I was a psychology graduate and teacher training drop out! With my experience of working in schools and academic research into young people’s substance use, I started working as an Education Lead for one of CGL’s young person’s services. After a year I applied to join the Business Development Team, wanting to utilise my experience of working frontline and my love of research and writing. I’ve progressed from Assistant to Officer and then Senior Officer since joining the team in 2022.  

How would you describe the team? Helpful, real and full of knowledge. Everyone comes from different backgrounds and is happy to share their skills, knowledge and learning. I’ve never felt like I’ve asked a silly question, and I don’t feel like I must put a on ‘work mask’.

What would you say to someone thinking of applying? Not to think they can’t do it just because they don’t have experience in bid writing or business development. It’s more important to be able to demonstrate that they’re a confident professional writer and are really passionate about working in the drug and alcohol support sector.”
