The provision of adequate heating throughout a property is considered under Hazard 2 (excess cold) and Hazard 3 (excess heat) of the operational guidance of the HHSRS.
In assessing the deficiencies that may give rise to such hazards, an inspection of the property will examine the thermal efficiency of the building with regard to heat loss through the external walls and roof; the size, extent and design of any fixed heating and ventilation systems; and any disrepair that may contribute to these hazards.
Where the house is not provided with central heating to the whole of the dwelling, it must be adequately and efficiently heated with the provision of permanent, fixed heating appliances or space heaters. Any heating system should be appropriate to the design, layout and construction of the building and provide adequate heat output to efficiently heat the whole of the property.
Any heating system should be economical and capable of achieving a healthy indoor temperature of 21ºC for each habitable letting room, and 18ºC in all other rooms and common areas.
Any form of heating must be controllable by the occupier and safely and properly installed and maintained.
In properties where the heating is centrally controlled, such systems should be operated to ensure that occupants are not exposed to extreme indoor temperatures, and should be provided with controls to allow the occupants to regulate the temperature within their dwelling.
Coin-operated heating and/or hot water systems in common rooms and common parts are not acceptable.
