BENCHMARK SCORE / OBSERVED EVIDENCE
These scores combine reputation, presence, credibility and review-count scale. Ordered comparisons require independently corroborated identity, primary-site electrical scope, a valid rating and at least ten reviews; a displayed score also requires at least 3 observed inputs. Companies with insufficient evidence remain unscored. They can include commercial firms; the residential ranking above uses its own disclosed eligibility and rating formula.
239 of 245 company listings have a displayed Benchmark score; 6 are unscored. Source observations: Oct 27, 2026; display rule corrected Oct 28, 2026. Unscored listings are excluded from score-summary denominators.

QUESTIONS / AS OF OCT 27, 2026
By volume-adjusted Google rating, the leading residential electricians in the Oct 29, 2026 Denver edition are Kappler Mechanical Heating & Air Conditioning (#1), Colorado Home Services (#2) and Sundog Electric LLC (#3). They lead 95 ranked listings; Google reviews were observed Oct 27, 2026. Ratings are customer opinions, not inspections.
95 of the 245 company listings evaluated in Denver are ranked in the Oct 29, 2026 residential edition. The other 150 have no residential rank because residential scope was not established from the company’s own pages, the listing’s branch identity was not corroborated with high confidence, or it had fewer than ten Google reviews.
Residential order uses (reviews × rating + 100 × 4.6) ÷ (reviews + 100), with at least ten reviews, corroborated branch identity and company-advertised residential electrical scope. The separate Benchmark score measures observed public evidence across reputation, presence, credibility and scale.
Colorado separates an electrician’s personal license from the electrical contractor’s business registration. For Denver-area work, check the DORA business record and then the permitting office for the property. Denver, Aurora and Arvada maintain their own project processes, so a state registration alone does not prove that local permit requirements are complete.
No. The 245 evaluated listings are a bounded search sample from principal-city and suburb queries. Search limits, hidden addresses, website access failures and withheld possible personal names affect coverage. The dated company records show what was established.
No. Reviews describe customer opinions, advertised services are company claims, and an issuing-authority record is a dated observation. Ask for written electrical scope, permit responsibility, insurance and a current license check for your address.
