The voucher book scheme being run as the current part of "Wasting Energy Costs the Earth" is a welcome contribution by business to encouraging action on energy efficiency among domestic householders. It involves the provision of discounts or special offers by manufactures, suppliers and trade associations at their own expense to complement the Government's own spending on the campaign.The discount relating to cavity wall insulation is no longer to be provided solely by one company. It covers the major designers of fibre-based systems and installers who are members of the industry guarantee scheme or the National Cavity Insulation Association.In supporting the voucher scheme the Government took full account of the long-term benefits to all sectors of the energy efficiency industry from a stimulation of the market, and decisions on individual contributors were taken on a value-for-money basis throughout.
