The system is the search: heat pump, boiler replacement, underfloor, ducted. A page per system with an installed price range and the running cost answers the comparison people are genuinely making.
Grants and efficiency schemes decide when a replacement happens. Naming the current programme, what it requires and what it pays, with the date visible, turns a reader into a survey booking.
A breakdown in January and a planned replacement in May are two different jobs. Kept on one page, the urgent customer scrolls past the long explanation and the planner never sees the reassurance they needed.
