I had someone wearing a hi-viz jacket with Surveyor on front and back but no other id knock on my door in Lydden on Monday, saying they were in the area checking that everyone had their government grants for home insulation - he didn't get the chance to stay long.
At our parish council meeting yesterday our clerk said she had someone making similar claims knock on her door yesterday just after she had downloaded an alert from trading standards saying these people had been in the Hildenborough area trying to get homeowners to pay for unnecessary surveys.
She has reported this activity to trading standards but it isn't on their website yet
