The Building Regulations 2001
The Building Regulations (Part L) now govern the installation of both new and
replacement boilers.
In summary, a minimum level of efficiency has been set for boilers (in terms
of the proportion of useful heat energy extracted from the gas), and time and
temperature controls must be installed with an interlock to positively shut down
the boiler when demand is satisfied or turned off. Sleeping areas must also have
separate temperature control from the living areas.
Further requirements are that boilers are commissioned in accordance with the
manufacturer's instructions (which usually specify cleansing of the pipework and
radiator system), and the BenchMark
log book is completed to confirm compliance with the regulations and left with
the customer.
Detailed information about Part L of the Building Regulations 2001 is
