Ten people in Brighton and Hove could win home energy improvements worth up to £10,000.
The green prizes are being offered by Brighton and Hove City Council as part of the Green Deal Pioneer Places scheme.
To take part, people need to apply for a Green Deal energy assessment with no obligation to follow any of the energy-saving recommendations.
The council said that it would carry out 100 free energy assessments to help residents see how they could waste less energy and save money on gas and electricity bills.
The ten prizewinners could be in line for a free new boiler, wall and loft insulation, secondary glazing and draught-proofing.
The council is working with three partner organisations – Brighton and Hove 10:10, Low Carbon Trust and the Green Building Partnership.
They recently applied for and won £221,000 of government funding for Brighton and Hove to be one of the Green Deal Pioneer Places.
The Green Deal is the government’s scheme to allow people to pay for energy improvements to their homes through the savings on their energy bills.
The Green Deal Pioneer Places competition is open to all Brighton and Hove homeowners, landlords and tenants, although not council tenants.
Anyone interested in taking part should visit www.brighton-hove.gov.uk/greendeal and fill in the online application form by the deadline of Monday 11 February.
Alternatively call the Green Building Partnership on 01273 411143.
The council said that even those who aren’t selected for the home improvements can use the assessment, which is worth up to £150, to take part in the Green Deal.
The council will randomly select the homes for the 100 Green Deal assessments from completed application forms and ten homes will be chosen from the 100.
