Landlords must also make sure the alarms are in working order at the start of each new tenancy.
Where properties are found to missing detectors the Council must serve a remedial notice on the landlord requiring them to be provided.
If a landlord fails to comply with a remedial notice the Council must do the works themselves and may serve a penalty charge notice of up to £5,000 (£1,000 for a first offence in Stafford).
The law requires that the Council publish a statement of reasons that will be followed when deciding the amount of a penalty charge. This statement can be found in the Smoke and Carbon Monoxide Alarm Regulations - Statement of Principles.
More information can be found in the Smoke and carbon monoxide: alarms explanatory booklet for landlords.
