People living in the Portsmouth area have been warned about cold callers offering to spray foam insulation for lofts.
Trading Standards officers from Hampshire County Council said the callers may claim they are working on behalf of local authorities, and make exaggerated claims about the foam’s ability to prevent heat loss.
They may also talk about the savings that can be achieved balanced against the cost of installation.
Claims that existing glass fibre insulation no longer meet current regulations are untrue.
Officers have warned that the spray foam can cause problems if not applied correctly, such as lack of ventilation to the roof space.
The foam may also be hard to remove so it is essential to research the suitability of the foam before having it installed.
Consumers are advised not to agree to work offered by cold callers , but first get at least three written quotes from businesses or traders who are either members of the Hampshire County Council Trading Standards Buy With Confidence Scheme or a recognised trade association.
If anyone has any information about traders who are cold calling or requires any advice on doorstep crime they can contact Hampshire County Council’s Quick Response Team on 01962 833666 (Monday – Friday 0900hrs to 1700hrs) where specially trained officers are on hand to provide advice.
