Halstead — an installer
Somebody comparing three quotes and a subsidy is not browsing. They are building a spreadsheet in their head, and the site that answers in that order wins the survey.
The signature is the installation index: completed jobs as full-width rows carrying the size, the date and the saving, so the page reads as a record rather than as a gallery. Forms handle the survey request; the installations are CMS entries.
Solar, heat pumps, glazing, insulation, kitchens, bathrooms, roofing, chargers — the shape is the same.

Every one of these was somebody’s Tuesday afternoon.
Twelve starting pointsYou are copying a site, not a wireframe.
Whichever one you pick, it lands in your account with its pages, its brand tokens, its content and every module the design depends on already configured. Nothing is shared with the original — change the prices on day one and no other site moves.
Three more, chosen by nobody.
The index is generated from the same twelve entries, so it is never out of date and nobody has to remember to update it.

Change the words.
Keep the machinery.
Or start from an empty page and build it yourself — by hand, or by describing it to an agent.
