This follows 70 notices which have already been served since the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 came into force.
The Council’s Housing Standards Team are currently working through phase two of the regulations to improve ensure properties legally have a minimum rating of E, irrespective of the tenancy start date.
All private rented properties are being reviewed and any that provide low levels of energy efficiency - including poor heating, lack of insulation, draughts, or single glazed windows - identified.
Fines will be enforced when works are not carried out.
Portfolio Holder for Communities, Councillor Wendy Bowkett, said: "The regulations were introduced to ensure that tenants can live in homes with adequate levels of heating and insulation, and whilst we will always assist landlords to comply with their obligations, we will also take robust action against those landlords that fail to provide their tenants with a property that is decent and safe."
