Slide 2Download slide imagePolished
Slide 3Download slide imagePolished First KPI caption wraps awkwardly ('year)' orphan), so its number sits higher than the other two and the cards don't align
Slide 4Download slide imageAcceptable The right-hand panel is text-heavy, with closely stacked explanations that require sustained reading.Y-axis is truncated at 2,000, which visually exaggerates the October jump and the gap between the lines
Slide 5Download slide imageAcceptable The complaints comparison is repeated in the chart, table and explanatory panel, adding visual bulk without much additional emphasis.Large empty gap between the table and the callout box
Slide 6Download slide imageAcceptable The dominant chart compares annual running costs, but does not visually demonstrate the three-year payback highlighted in the title.Chart compares running costs but does not visualise the ~3-year payback named in the title; a cumulative cost line would carry the message better
