§ Mrs. MayTo ask the Deputy Prime Minister what recent estimate he has made of the cost per household of improving sound insulation in houses affected by poor sound insulation. [60661]
§ Mr. McNultyThe Office of the Deputy Prime Minister has not made an estimate of the cost of improving sound insulation for the existing housing stock. However, in a House of Lords ruling on two Appeal Court cases determined in 1999, it was estimated that the average cost of installing sound installation in the flats in question was £8,000 per flat. The cost in any particular case would depend on the nature and extent of the work required.
