The next year he set up the service's first volunteer team. At that point there were ten of them; today there are 100 uniformed voluntary members, who in the last year gave more then 10,000 hours of their time. Ranging in age from 17 to 72, they help educate vulnerable groups about fire safety, work in the community to cut arson and hoax calls, and give practical help like fitting smoke detectors.
Volunteers are full of appreciation for the long, unsociable hours Aldwin puts in to make sure they're supported, dropping in on their work in evenings and at weekends and always being available on the end of the phone, says team leader John Briffett. "I believe Roy has played an inspirational role in the development of this volunteer scheme and truly feel it would not be achieving what it does today without him," he says.
Aldwin, who's been involved with volunteering since he was 18, including as a special constable - he received a long service award before retiring from the role in 2007 - says he's driven by a desire to help vulnerable people in particular. "I absolutely love working on community safety issues - anything that improves the safety and environment we live in," he says. "That's what it's about. I've done that all my life."
He's as effusive about the volunteers as they are about him. "They don't replace anything we've done previously, they enhance it. They're the unsung heroes. They're so professional people think they're part of the service, even though their uniforms say that they're volunteers.
"We've attracted an outstanding group of people. They're amazing." Some have even become personal friends.
Another benefit of the scheme, which is soon to expand into trading standards work to help stamp out rogue traders, is the opportunities for personal development it offers volunteers. "Many people come to us when they're unemployed and have gone back into full-time employment," Aldwin says. "They've all said it helped them through that period of unemployment and helped them get new roles." The experience of seeing his team members grow in their roles is "wonderful", he adds. "I had a dad come up to me and say his son was more confident, helpful, driven. I felt really humbled - I said 'it's not me, it's the service!' It's a really nice scheme, it really is."
Aldwin, who is married with daughters aged 15 and 21, is also an active school governor and manages a partnership between local businesses in Hemel Hempstead to reduce crime in the town, a role that is part paid and part voluntary. "I can't express in words how delighted I am," he says of being shortlisted for the public servant of the year award. "For me, it recognises all the volunteers I work with. I love that."
