Five people are to be made redundant after Swinton Insurance announced it is closing its Spalding branch.
The announcement brings an end to a long history of insurance brokers in the New Road building which previously housed the family business Norman C Williams.
Swinton took over that business in 2009 and has been part of the insurance giant since.
But last week it announced it was closing 40 stores, including the Spalding branch on March 29.
A spokesperson for Swinton said: “We are reducing our branch numbers because the majority of customers now buy insurance us over the phone or through the internet.
“As a result, our branch on New Road in Spalding will be closing on March 29.”
In a statement that announced the branch closures which affected 268 people across the country, Swinton said: “Our distribution model continues to evolve so that we meet the changing needs of our customers in an effective and efficient way.
“While these changes are always difficult for colleagues, especially those who are directly impacted by the proposals, they are vital if we are to remain competitive in a challenging insurance market.
“At the same time, we continue to invest in the business.
“This includes a £35m investment in the successful introduction of a new IT system to enhance our digital capabilities, and an increased marketing spend this year of £20m to improve our brand awareness.”
