More than 200 people have signed a petition calling on HSBC to keep the branch in Market Deeping open amid global cuts.
The branch in Market Place is due to close on August 28, according to a sign in the window.
The bank is cutting staff numbers globally, with up to 8,000 jobs at risk in the UK.
A petition calling on HSBC to keep the Market Deeping branch open had more than 220 signatures at the time of going to press. The petition was set up by Market Deeping resident Adam Brookes, a Liberal Democrat candidate in the upcoming South Kesteven District Council election on June 25.
Deepings Business Club chairman Andy Pelling said the closure would hurt businesses and community groups. He added: “Deeping is a thriving community with a lively town centre, an expanding industrial estate and ever increasing numbers of houses. I feel this is a short-sighted measure by HSBC which is likely to lose them a lot of customers to their competitors and may well be a blow for a reviving town centre.”
An HSBC spokesman said the number of customers using branches had dropped by 40 per cent over the last four years.
