In March 2000 I increased the grant levels available for new group water schemes and the upgrading of existing substandard schemes from 75% of the approved cost, subject to a cost limit of £1,600 per house, to 85% of the approved cost, subject to a cost limit of £6,000 per house. In areas not served by either a group scheme or public supply, grant aid of 75% of the approved cost, subject to a grant limit of £1,600 per house, is available for the provision or necessary improvement of an individual water supply to a house.
