The council is offering low-priced or free home insulation in time for Christmas.
The offer is part of Energy Saving Week and the Brighton and Hove Warm Homes scheme.
Brighton and Hove City Council said that anyone who owns, leases or rents a home from a private landlord in the city, and has a suitable property, is eligible.
On offer is loft or cavity wall insulation supplied and fitted under the scheme for a typical price of £148.
This can vary depending on the size of the property.
For residents aged 70 or over the scheme offers free loft and/or cavity wall insulation.
The council said that even if a loft has been insulated in the past it may need a top up of insulation now.
Councillor Maria Caulfied, the council’s cabinet member for housing, said: “This is a great scheme that will help keep homes warmer, heating costs down and reduce CO2 emissions.
“At very little or no cost to private landlords suitable properties can have their lofts or cavity walls insulated or even both.”
Brighton and Hove Warm Homes is a partnership between the council, its managing partner Climate Energy and EDF Energy.
The scheme was set up almost three years ago.
Energy Saving Week is an annual national campaign run by the Energy Saving Trust and this year it runs from Monday (25 October) to Sunday 31 October.
