The roof space, photographed from the hatch
- Today
- One frame among two hundred, kept because the estate agent wanted to show the attic could be converted. It never comes up again.
- With a system
- The report notes that the underside of the tiles is visible with nothing between the rafters, puts the roof insulation on the list with an order of cost, and links it to the label: this is usually the single cheapest step towards D, and it is the one a buyer can do without moving out.
