This invention generally relates to a system for estimating fuel consumption of a boiler in a building and to a method of estimating fuel consumption, in particular for estimating gas consumption. A system is disclosed for estimating fuel consumption of a boiler in a building, the system comprising at least boiler operating model configured to perform said estimating on the basis of at least one ON time of the boiler.

Fuel consumption estimation

A system to provide feedback for energy saving to a user of a property comprising a plurality of appliances, the system comprising: at least one sensor monitoring energy consumption of one or more appliances within the property; a user interface to provide feedback to the user; and a processor configured to receive input data from an energy bill for the property covering a predetermined period; receive input regional average statistics regarding energy consumption for a set of predetermined categories of energy usage; generate a model of energy usage within a plurality of categories over the predetermined period by combining the input data, energy consumption data from the at least one sensor and generic statistics regarding energy consumption and output, via the user interface, feedback to the user based on the generated model.
