A system transfers data to and from a control and/or metering means for gas, water or electricity in or adjacent a premises, relating to a utility or combination of utility supplies to said premises, to and from a remote data monitoring station such as that operated by the utility provider to allow remote meter readings. In one embodiment the transfer of data is achieved via a power line carrier or radio signal from the control and/or metering means to a communication means in the premises and then via a telecommunications line to the remote data monitoring station thereby providing a suitable system which can utilise existing facilities to transfer data.
