Iain McKenzie – 2014 Parliamentary Question to the Department for Energy and Climate Change

The below Parliamentary question was asked by Iain McKenzie on 2014-03-26.

To ask the Secretary of State for Energy and Climate Change, what estimate he has made of the average time it takes for householders who have installed energy efficient products in their property to recover their costs; and if he will make a statement.

Gregory Barker

The Department’s latest estimates for households installing energy efficient products in their property do not assume a single payback period. The time required to recover installation costs will depend on a large number of factors, specific to the household. Some of the main influencing factors are: the property’s type and size; the measures installed and their cost; the household’s pattern of energy use before the installation; the energy efficiency of the property before the installation; and whether or not there was a subsidy to contribute to the measure’s cost.

All the Department’s take-up projections for energy efficiency measures assume that the households installing measures will recover all the installation costs, with payback ranging from 0 to 25 years.
