Mr Trott was recognised in last year’s New Year’s Honours for a quarter of a century of service to the community.
He said that the inauguration was a wonderful occasion and he enjoyed a brief and light-hearted chat with the Prince.
‘It was a privilege to speak with him and to receive the award from him,’ he said.
The Prince has never visited Guernsey but Mr Trott said he had told him that he hoped to visit one day.
‘I said that while I can no longer speak on behalf of our community, I knew unreservedly they would be most welcome, and hoped their visit would be soon.
‘I explained that as I was no longer a public servant, I might not make the invitation list for their visit, so wondered if he might put in a good word for us, which raised a laugh.’
Mr Trott stood down from the States in June, after 25 years in politics.
‘We discussed what I was now doing. I said that from the private sector, I was trying to pay as much tax as possible, which seemed to meet with his approval.
‘The whole ceremony was faultless in every sense. An honour and a privilege, wrapped up in a fantastic day enjoyed by us all.’
Mr Trott was there with his family, wife Karen and children Jack, Jodie and Seren.
At the time of the announcement of his honour, he said he was proud to have served ‘a very special community’ in what had been ‘a team effort’, and he thanked his family for their support.
‘They, like the families of all those who enter public political life, give a huge amount in terms of support, patience and understanding.
‘Politics in a small and passionate community is often intense, it seldom makes you popular, and it takes up a lot of your life, which is fine as a personal choice, but it’s harder to ask it of your family, and my family has been incredibly supportive and I can’t thank them enough.’
Deputy Trott was first elected to the States in St Sampson’s in 2000.
He served that parish until 2020, when he finished ninth in the first island-wide election.
He held the top job in the States between 2008 and 2012 and again for the last 18 months of his time in politics.
He was also involved in the Commonwealth Parliamentary Association, serving as the unpaid independent trustee of the Commonwealth Parliamentary Trust Funds.
He also chaired Guernsey Finance pro-bono for the best part of a decade.
Before entering politics he worked in financial services, and still does as a chairman and non-executive director, and also spent time as a commercial fisherman. He is well-known for his passion for ormering on the spring tides.
