Scam alerts across the district have been raised as individuals pretend to be from Thermotech to target residents.
Newark and Sherwood District Council took to its social media and alerted residents to the scams going on around the district.
The people claiming to be from Thermotech claim to be sent by the borough council and claim that the loft insulation foam in the residents’ houses is not right and needs to be replaced.
They quote a few thousand pounds and demand payment on the spot.
The Borough Council is reminding people to check the identity of anyone who comes to their door to ensure they work for who they say they do and not give them their bank details.
If in doubt, residents are advised to call 01636 650 000.
Another ongoing scam is fake texts to customers relating to cost of living payments and winter heating allowance, known to the Department for Work and Pensions.
The latest seen by the council include the text — Winter cold welfare reminder — and asks readers to update their details at the link provided.
People should not use the link to give out their personal details or respond to any suspicious text messages and to only go through official government websites.
