So far, 263 ratepayers have already received a rates advance through the Dunedin City Council's Warm Dunedin pilot.
There was enough funding for 700 homes in total, council energy manager Neville Auton said.
The pilot complemented the Energy Efficiency and Conservation Authority (EECA) Warm Up New Zealand: Heat Smart programme, which was still offering funding for installing insulation in medium-income homes.
Other funding and assistance programmes were also available to help people meet the costs of insulating and heating their homes.
The Warm Dunedin programme would stop either on August 31, when the council's fund ran out, or when the EECA grants ran out.
People told their applications were on hold pending an extension of the programme, would be contacted by their installers in due course, Mr Auton said.
Ratepayers who met the criteria could apply for upto $5000 towards insulation and/or heating, to be paid off over 10 years using a targeted rate.
