About WholeHouseGeneratorCost.com

A reference for the cost of whole-house standby generators in the US: equipment, installation, fuel-line work, automatic transfer switch, permits and ongoing maintenance. Operated by Digital Signet, founded by Oliver Wakefield-Smith.

The reason this site exists

Whole-house generator pricing varies by 3x for nominally similar systems: a Generac Guardian 22kW install can run anywhere from $9k to $20k+ depending on fuel-line scope, ATS class, electrical-panel readiness and local permit cost. Most top-ranking pages are written by national dealers or quote sites chasing a form fill. This site publishes defensible cost bands by generator size and install scope with the assumption set behind each. We do carry a labelled Angi link, and it pays us a little if you use it.

About Digital Signet, the operator

This site is operated by Digital Signet, an independent AI-development studio founded by Oliver Wakefield-Smith. It is part of a portfolio of consumer cost-reference and calculator sites we run as a live R&D lab for our Signet methodology, an autonomous AI development team that ships real software at scale.

Digital Signet does not sell generators, does not act as a Generac / Kohler / Cummins dealer, does not run a generator install practice, and does not accept paid placements from any generator manufacturer or dealer-network. Editorial direction is set by Oliver. Drafts are produced via Digital Signet's autonomous AI development methodology and reviewed against the editorial framework before publication.

Editorial principles and disclosures

  • Source pattern. Built on public reference material across the relevant publisher landscape.
  • How the site is funded. Some pages carry a labelled Angi link through the CJ affiliate network, and the site may earn a commission when a reader submits a request through it. That link never changes the cost figures, the brand comparisons or which brand a page favours. The site does not sell generators, is not a Generac, Kohler, Cummins or Briggs and Stratton dealer, and does not run an installation business.
  • Math is documented inline. Where the site has a calculator, inputs and assumptions are visible on the calculator page. Nothing is hidden behind opaque scoring.
  • Update only when underlying reality changes. Triggers: Manufacturer announces a published list-price change; Major hurricane / wildfire / grid-resilience season that materially shifts demand and pricing; Material movement in published electrician / gas-line install day rates over a 12-month sample; Updated NEC / IRC code requirements affecting generator install scope.
