GCA chairman Will Armitage said: "The annual inspections take place from March 17 until June 13 and will begin with an assessment from an independent inspector.
"Once this is complete, the inspector will discuss his/her findings with the garden centre’s owners, managers and staff in a constructive feedback session. This allows the management team to make any changes necessary, based on the findings, straightaway.
"Many GCA members have said that the unique annual inspections and constructive feedback sessions are one of the biggest benefits of membership. It is a fantastic motivational and management tool and really keeps staff on their toes, making sure they are always doing their absolute best.
"Garden centres receive no advance warning about when their inspection will take place and they do not have the option to turn away the inspector. It is all about making sure they are offering a consistently excellent service and improving their customer service standards, which is what all GCA garden centres must do to remain members."
This year’s inspectors are: Liz Hutson, Andy Campbell, Ian Boardman and Roger Crookes. The four have already met recently for a ‘consistency day’, where they each did a trial run inspection and then checked they were marking consistently with each other.
