More than 200 homes had no contents insurance for their personal possessions and household items which were lost in the floods.
In data released by Boston Borough Council, it was revealed that 225 of 497 people who responded to a survey had no contents insurance.
A spokesman said the survey was sent out to affected properties following the floods and clean-up activities this week.
Initial results had appeared to show that just five of 424 properties had contents cover.
Lesley Draby, of Edwin Street, Boston, is one of those without cover for her possessions.
She said she simply hadn’t thought about it at the time: “I didn’t think any of it would have happened.
“I wish I had now. Everything downstairs was lost including all my kids’ stuff.”
She said that now she was in a new home she would be looking to getting insurance.
Ali Eryigit, also of Edwin Street, Boston was also without cover.
He said he simply couldn’t afford it because he only worked 24 hours a week and had to support two teenage children.
Mr Eryigit lost his tumble dryer, washing machine, fridge and carpets which only went in six months ago.
Boston Borough Council said there are 54 streets affected by the floods with 497 homes hit.
Of these, six are ‘high priority’, which could include residents who were vulnerable through age, health, pregnancy, children, no utilities – all receiving assistance.
There are also 61 at medium risk and being supported.
There are still thought to be eight families in temporary accommodation provided by Boston Borough Council.
There are also 64 people said to be in temporary accommodation of their own arrangement.
