The deal was announced at a press conference on Wednesday at Kingsholm Stadium, at which the club also unveiled a sneak preview of their new look home shirt for the 2013-14 season.
ADEY is an award winning Gloucestershire company that has enjoyed spectacular growth in recent years. The business invented and produces the MagnaClean filters that maintain and protect central heating systems in nearly two million UK homes.
The former Gloucestershire Business of the Year and Queen's Award for Innovation winner
continues to invest in ongoing product development. The company has previously been listed in the Sunday Times Fast Track 100 as the fastest growing independent manufacturing business in the country.
Gloucester Rugby CEO Stephen Vaughan explained that the search for a new main sponsor had been a long, exhaustive one but that ADEY are absolutely the right partner going forward.
"It was hugely important to us to find the best possible match having enjoyed six great years with our previous main sponsor Jewson.
"The process has been ongoing since pretty much the start of the season, and we've obviously spoken to a number of potential partners with a high level of interest.
"However, ADEY are exactly the right fit. They're a young, dynamic company, a success story with their roots in the county. They also have aspirations to expand into Europe and we genuinely hope that we can help them achieve that.
"We're delighted to have them as Gloucester Rugby's new main sponsor and look forward to a long fruitful working relationship with them."
ADEY's Managing Director Kelvin Stevens accepted that the announcement represented a big step for a company that ten years ago was operating from a garden shed.
"We're used to moving quickly and taking sizeable steps and are delighted to be supporting Gloucester Rugby as main club sponsors. The sponsorship will raise our profile beyond the UK heating industry and help us continue our impressive growth in the future.
"While we clearly don't have the long tradition of one of the strongest and best supported rugby clubs in the country, we've come a long way and achieved a huge amount in a short period of time.
"Gloucester Rugby is built on pride and passion and similarly we're extremely passionate about what we do and proud of our success to date. We're a dynamic organisation, ambitious and we believe we've also got a team with exceptional potential.
"And, like Gloucester, we've set our sights firmly on success in Europe, so we have a lot in common.
"All of this is backed up by market leading products that protect heating systems and deliver tangible benefits for householders and the environment.
"We're really looking forward to working with Gloucester Rugby to ensure we communicate these positive messages and achieve our goals together."
