7.1 On completion of the work, in accordance with regulation 40, the owner of the dwelling should be provided with sufficient information about the building, the fixed building services and their operating and maintenance requirements so that the dwelling can be operated in such a manner as to use no more fuel and power than is reasonable in the circumstances. This requirement applies only to
the work that has actually been carried out, e.g. if the work involves replacing windows, there is no obligation on the contractor to provide details on the operation of the heating system.
7.2 Where the work involves the provision of a new heating system, a way of complying would be to provide a suitable set of operating and maintenance instructions aimed at achieving economy in the use of fuel and power in terms that householders can understand
in a durable format that can be kept and referred to over the service life of the system(s). The instructions should be directly related to the particular system(s) installed as part of the work that has been carried out.
7.3 Without prejudice to the need to comply with health and safety requirements, any instructions should explain to the occupier of the dwelling how to operate the system(s) efficiently. This should include:
a. the making of adjustments to timing, temperature and flow control settings;
b. what routine maintenance is needed to enable operating efficiency to be maintained at a reasonable level through the service live(s) of the system(s).
